    Opis:
    The aim of this study was to analyse absolute and relative reliability of a number of postural static stability measures obtained from a GYKO inertial sensor system in young adults. Methods: The study examined 29 healthy non-athlete young adults. A test was performed for 30 s while standing on one foot, without moving, with eyes open and arms relaxed along the sides of the body. The examinations were performed twice, with a one-week interval. Relative reliability was measured using the intraclass correlation coefficient (ICC) and the 95% confidence interval (95% CI), whereas the absolute reliability was evaluated based on the standard error of measurement (SEM) and the minimal detectable change (MDC). Results: The results of this study showed moderate to good relative reliability scores for all the postural stability measures, with ICC values ranging from 0.62 to 0.70. For most of the analysed variables, SEM% ranged from ca. 10 to 14%. Relatively high SEM% values were obtained only for two variables (Area, Convex Hull Area). Conclusions: The low costs of GYKO inertial sensor systems, the fast and easy installation, the mobility and high reliability of the measurement of postural stability show that it can be effective alternative to stabilographic platforms.

    Opis:
    The aim of this study was to investigate whether a single bout of core stability exercises improves body balance immediately after the bout of exercise and during a retention test. Methods: The study involved 16 women (age 22–25 years, body weight 60.5 ± 5.2 kg, height 166 ± 5.4 cm). Postural stability was assessed in the mediolateral (ML) and anteroposterior (AP) planes separately on a force plate (Kistler 9286 AA) during quiet standing on a soft support surface with the eyes closed. Subjects were measured 4 times: just before (T0), 1 minutes after (T1 m), 30 minutes after (T30 m), and 24 hours after the workout (T24 h). Postural balance was evaluated by five parameters based on the center of pressure (COP) signal: variability (VAR), mean velocity (VEL), sample entropy (ENT), frequency (FRE), and fractal dimension (FRA). Results: We observed a decrease in VAR and VEL in the ML plane at T30 m and T24 h, compared to T0. The COP entropy significantly increased in the ML plane at T24 h, compared to T0. Conclusions: A single bout of core stability exercises improved the control of the mediolateral body balance. This effect was evident within 30 minutes after exercise, and remained for at least 24 hours. In addition, 24 hours after exercise we observed an increased automaticity in the strategy to maintain a stable upright stance.

    The objective of this paper is to study the margin of stability when trying to lean out the body forward and backward. The centre of mass of the body, the velocity of the centre of mass and extrapolated centre of mass were calculated for four participants. The analyzed movement was recorded by using BTS Motion Capture system. Recordings, in which participants were unable to return to the upright position, were also observed. In these cases, it was verified the usefulness of extrapolated centre of mass for predicting the foot support area that enables maintaining the body balance. The relationship between the applied stability indicators and anthropometric parameters was determined. The preliminary results obtained confirm the validity of the use of selected parameters in tests and in assessment of the stability of the human body, and indicate the directions of further tests for a larger group of participants and other movement activities.

    Opis:
    The aim of this study was to evaluate the reliability of the novel posturographic procedure and to investigate the relationships between parameters of this procedure and clinical tests. We hypothesised the proposed step initiation procedure to be reliable method of balance and motor disability assessment, especially in patients with neurological deficits. Also, we assumed high significant correlation between parameters of step initiation procedures and clinical tests. Methods: The 35 subjects with idiopathic PD and 35 agedmatched healthy controls participated in this study. The gait initiation was measured using two force platforms. The procedure consisted of three phases: (1) quiet standing on a first platform (2) crossing on the second platform, (3) quiet standing on a second platform. Testing was carried out in four conditions: unperturbed trial, obstacle crossing, step-up and step-down. Results: In the proposed gait initiation procedure, the vCOP, raCOP and rmsCOP showed an excellent reliability (ICC > 0.80). For transit phase, reliability of all variables in all conditions also was excellent (ICC = 0.8–0.9). There were only a few associations between Tinetti scores and posturographic variables in controls, but in PD patients the significant correlations were found between the proposed measures and the UPDRS, Tinetti, FRT, TUG and with the BBS. Conclusions: The proposed gait initiation procedure is reliable and very suitable for the assessment of patients with Parkinson’s disease. It can be used as an objective assessment of the clinical condition and dynamic balance, and help in the designing and programming of the appropriate rehabilitation and treatment.

    Opis:
    The aim of the study was to assess static balance after reconstruction of the anterior cruciate ligament (ACL), using gracialis tendons graft (GR) or semi-tendinosus (ST), compared to patients treated with the Ligament Advanced Reinforcement System (LARS). The study was performed within 36 to 48 months after the surgery. Methods: The study included 96 patients. The LARS group consisted of 44 patients, control group operated with ST/GR tendons included 52 patients. The stabilometric platform Alpha was used to assess the static balance. Two 30-second trials in the double-leg stance position with eyes opened and closed were performed. The distribution of loads in a free standing was also assessed. Results: In the test with open eyes the subjects from the LARS group had a significantly longer center of pressure (COP) path, a higher mean velocity, a greater mean COP sway in foot in the lateral direction and a larger path area occupied by the COP graph. During the tests with eyes closed, a significant difference occurred in the mean displacement of COP in lateral direction – greater in the LARS group. In addition, all parameters deteriorated during the tests with eyes closed in both groups. Conclusions: In static balance assessed with eyes closed, more proprioceptive deficits may appear in the LARS group.

    Opis:
    Purpose: The pain, motor and sensory deficits are common symptoms of the lumbar disc disorder, and they can significantly affect human postural control. The aim of this study was to assess postural stability in patients with severe symptoms of lumbar spine disc disease qualifying them for surgical treatment and to compare them with a control group. Methods The study involved 103 subjects: 54 patients and 49 healthy subjects. Patient’s mean age was 46.4 ± 11.3 years, mean body height 172.2 ± 10.3 cm, mean body mass was 83.1 ± 18.9 kg and mean body mass index (BMI) was 27.9 ± 5.2 kg m-2. The mean time of their recent pain episode was 9.7 ± 8.5 month. Results: We found statistically significant differences between postural stability in patients with lumbar spine disc disease and the control group. The measurements taken with eyes closed, as compared with the clinical control group, revealed higher and statistically significant values of the mean amplitude of COP, mean amplitude of COP on sagittal plane, and maximal sway in sagittal plane parameters. The analysis of pressure value differences between the right and left lower limbs in both groups revealed statistical significance. In the study population the difference was significantly greater in comparison to the control group. The patients has significantly greater asymmetry of lower limb load. Conclusions: 1. Patients with lumbar spine discogenic pain had decreased postural control. 2. The patients had significant asymmetry in foot pressure, resultant from pain radiating to a lower limb.

    Umiejętność utrzymywania równowagi spełnia ważne funkcje, nie tylko w życiu codziennym człowieka, ale również, odgrywa ważną rolę w wielu dyscyplinach sportowych. Jest to zdolność, która wymaga odpowiednich ćwiczeń, aby mogła jak najlepiej wpływać na wyniki osiągane w sporcie. Niestety niewiele osób uprawiających amatorsko Dart wie jak odpowiednio kontrolować równowagę, aby rzut w tarczę był jak najbliższy celu. Celem pracy jest przedstawienie podstawowych pojęć, koncepcji oraz metody umożliwiające analizę wpływu stabilności ciała na celność rzutu.
    The ability to maintain balance fulfills important functions not only in everyday life of man, but also plays an important role in many sport disciplines. It is an ability that requires appropriate exercises to influence on the success achieved in sport. Unfortunately, few people doing amateur Dart know how to properly control the balance to make throw the shield close to the target. The paper presents the basic concepts, approaches and methods of analyzing the influence of the stability of the body on throwing accuracy.

    Opis:
    The position of the trunk can be negatively influenced by many diseases. Several methods can be used for identifying defects in balance and coordination as a result of pathology of the musculoskeletal or nervous system. The aim of this article is to examine the relationship between the three methods used for analysis of trunk sway and compare two fundamentally different MoCap systems. We used a camera system and a 3DOF orientation tracker placed on subject’s trunk, and measured inclination (roll) and flexion (pitch) during quiet stance. Ten healthy participants in the study were measured with eyes open and closed. The pitch versus roll plots of trunk were formed, and the area of the convex hull, area of confidence ellipse and total length of the trajectory of the pitch versus roll plot were calculated. The statistical analysis was performed and strong correlation between the area of the convex hull and area of the confidence ellipse was found. Also, the results show moderate correlation between the area of the confidence ellipse and total length of the trace, and moderate correlation between the area of the convex hull and total length of the trace. In general, the different MoCap systems show different areas and lengths but lead to the same conclusions. Statistical analysis of the participants with eyes open and eye closed did not show significant difference in the areas and total lengths of the pitch versus roll plots.

    Opis:
    Identification of factors that affect postural stability may help to improve diagnostic accuracy and enhance the quality of treatment and rehabilitation. This study sought to assess the relationship between postural stability parameters and anthropometric factors of persons with hearing impairment (HI). Methods: The study included 128 individuals – 42 subjects with HI and 86 without HI (healthy controls). Research methodology included an interview and a medical examination, anthropometric measurements and stabilometric tests on platforms with stable and unstable surfaces. Results: In the group of female study participants with HI, significant correlations were only noted between body height and the Fall Risk Index (FRI). In the group of male subjects with HI, the study revealed significant correlations between FRI and body mass, BMI, % MM (muscle mass percentage) and % FAT (fat percentage). Moreover, moderate correlation was found between COP path with eyes open and body mass, while high correlation was observed between COP path with eyes open and BMI, % MM and % FAT. No significant correlation was noted between FRI and body height in men with HI. Conclusions: The examination of correlations between postural stability and body build of persons with HI did not confirm the effects of body height on postural stability in the examined group of individuals with HI, but revealed a greater influence of somatic parameters (body mass, BMI, % MM, % FAT) on postural stability in hearing-impaired men.

    Opis:
    The testing of dynamic balance involves tests that assess the muscle control of spatial changes of the position of the centre of gravity over the base of support. The purpose of this work was to determine the structure of the Y-balance test and its accuracy based on the measurements of strength performance of the muscles acting on the knee joint, as well as the flexibility and balance in boys aged 14 years. Methods: The study included 43 schoolboys regularly participating in physical education lessons. The examination of postural stability was conducted with the use of the Y-balance test. The measurements of muscle strength and of resistance to fatigue of the extensors and flexors of knee joints in isometric contraction were performed on a measurement stand in a standard position with the use of tensometric sensors. The measurement of mobility range of the lower extremity joints was performed according to the SFTR. The examination of balance was performed with the use of the modified ‘Flamingo balance test’. Results: The factor structure of the Y-balance test results for the left and right lower extremities is similar and includes five principal independent factors that characterise the structure of analysed variables. They explain 76% and 74% of communality in total for the left and the right extremity, respectively. Conclusions: The extracted factor structure points to a hybrid structure of the Y-balance test and shows its accuracy in the measurements of the lower limb joint mobility and strength performance of knee joint extensors.

    Streszczenie Wstęp: Ocena stabilności ciała przeprowadzona przy użyciu platformy stabilometrycznej stanowi obiektywną metodę diagnostyczną. Porównanie parametrów stabilogramów otrzymanych w badaniu z oczami otwartymi i zamkniętymi umożliwia umożliwia ocenę kontroli postawy z wyłączeniem informacji wzrokowej. Celem badań była ocena parametrów stabilogramu kobiet po 60 roku życia, w warunkach wyłączenia kontroli wzrokowej. Materiał i metody: Do badań zakwalifikowano 98 kobiet w wieku powyżej 60 lat (x = 71 lat). Przy użyciu platformy stabilometrycznej, oceniono równowagę pozycji stojącej w próbie z oczami otwartymi oraz zamkniętymi. Analizowano 6 różnych parametrów ruchu środka nacisku stóp (COP – center of pressure). Wyniki: 1. W warunkach wyłączenia kontroli wzrokowej, istotnemu wydłużeniu uległa długość ścieżki stabilogramu w płaszczyźnie strzałkowej. Wartości całkowitej długości ścieżki, średniego wychylenia, średniej prędkości oraz wielkości pola powierzchni zakreślonej przez COP uległy zmianie w badaniu z wyłączeniem kontroli wzrokowej, jednak zmiany te nie okazały się istotne statystycznie.2. Wyłączenie bodźców wzrokowych przyczyniło się do skrócenia (poprawy) długości ścieżki stabilogramu w płaszczyźnie czołowej. Wnioski: 1. Wyłączenie kontroli wzrokowej prowadzi do istotnego wydłużenia długości ścieżki stabilogramu w płaszczyźnie strzałkowej (SPAP); 2. Długość ścieżki w płaszczyźnie czołowej (SPML) ulega skróceniu w próbie z oczami zamkniętymi.
    Abstract Background: Assessment of the stability of the body performed by using stabilometric platform is an objective diagnostic method. Comparison of stabilograms’ parameters received from test with eyes open and closed, allows to assess the role of the visual senses involved in postural control. The aim of the study was to evaluate parameters of stabilogram of women over 60 years of age without visual control. Material and methods: 98 women (over 60 years of age, x = 71 years old) participated in the study. Standing balance was assessed in the trial with eyes open and closed, by using stabilometric platform. Six different motion parameters of center of pressure (COP) were evaluated. Results: 1. The results of this study indicate that in the trial without visual control, the path length in the sagittal plane was significantly longer. The values of: total path length, mean amplitude, mean velocity and sway area have worsened in the trial without visual control, but the result was not statistically significant. 2. Disabling visual control has contributed to reduction (improvement) of path length in the frontal plane.Abstract Background: Assessment of the stability of the body performed by using stabilometric platform is an objective diagnostic method.

    Opis:
    Postępujący charakter stwardnienia rozsianego pogłębia ubytki neurologiczne oraz niepełnosprawność, która w niektórych przypadkach przybiera postać znacznego inwalidztwa. Do naj-częstszych problemów osób z SM (multiple sclerosis) należą zaburzenie chodu i równowagi. Różnorodność i zmienność objawów oraz trudny do przewidzenia przebieg choroby powodują, że rehabilitacja chorych jest skomplikowanym zadaniem. Celem pracy było określenie wpływu ćwiczeń równoważnych oraz ćwiczeń koordynacji wzrokowo-ruchowej (biofeedback) na stabilność postawy osób ze stwardnieniem rozsianym, zobrazowaną wielkością marginesu stabilności. Badaniami objęto 20 osób z SM w wieku od 22 do 67 lat. Efektem zastosowanych ćwiczeń było uzyskanie istotnie większego przedniego marginesu stabilności (p = 0,00004). Natomiast tylny margines stabilności uległ nieistotnej statystycznie zmianie. Uzyskany istotny wzrost parametru koordynacji wzrokowo--ruchowej (p = 0,0003) wskazuje na większą skuteczność świadomej autokorekcji postawy z zastosowaniem wzrokowego sprzężenia zwrotnego. Uzyskane wyniki dowodzą większej sprawności kon-troli postawy u osób chorych na SM po fizjoterapii.
    Progressive nature of the multiple sclerosis (SM) results in the increase of neurological defects and the intensification of disability which in some cases turns into notable invalidity. The most regnant symptoms of SM are gait disorders and impaired balance. Rehabilitation of patients suffering from SM is complicated due to the variability and changeability of symptoms and difficulties in predicting illness course. The aim of the study was to examine the influence of the stability training and visual-motor coordination exercises (biofeedback) on the body stability. 20 patients between 22 and 67 years of age were enrolled into this study. The result of exercises was significance improvement of front stability margin (p = 0,00004). However, back stability margin insignificantly changed insignificantly only. The significancet improvement of visual-motor coordination (p = 0,0003), was observed, it means the improvement of the effectiveness of self correction of posture based on a conscious visual control of own posture (biofeedback). This study has shown that physiotherapy resulted in better postural control of patients with SM.

    Opis:
    Celem pracy była ocena stabilności posturalnej podczas strzelenia z łuku. W badaniach wzięły udział dwie grupy: zawodowi łucznicy oraz amatorzy, tzn. osoby, które nigdy nie strzelały z łuku. Badania zostały przeprowadzone przy użyciu systemu Vicon i platform Kistler. Do obliczeń zostały eksportowane położenia środka masy ciała. Następnie została policzona długość drogi CoM w przestrzeni 3D oraz współczynniki entropii próbkowej. Wykazano, że długość drogi CoM w przestrzeni 3D jest istotnie (p = 0.0001) dłuższa u łuczników podobnie jak współczynnik entropii próbkowej wzdłuż osi pionowej (p = 0.0117).
    The aim of the work was to assess postural stability during archery. Two groups participated in the study: professional archers and amateurs, i.e. people who never shot a bow. The tests were carried out using the Vicon system and Kistler platforms. Body mass center positions were exported to calculations. Next, the CoM distance in 3D space and sample entropy coefficients were calculated. It was shown that the distance of the CoM path in 3D space is significantly (p = 0.0001) longer in archers, similarly as the sample entropy coefficient along the vertical axis (p = 0.0117).

    Opis:
    Celem pracy była ocena stabilności posturalnej w różnych warunkach podparcia: stanie obunóż, jednonóż i w tandemie przy oczach otwartych. W badaniach wzięła udział grupa trzydziestu trzech zdrowych osób w wieku 21.88 ± 1.65 lat. Badania zostały przeprowadzone przy użyciu platformy AMTI AccuSway (30 sekund – każda próba). Do obliczeń eksportowano położenia środka nacisku stóp na podłoże (CoP) w płaszczyznach x i y. Następnie została policzona długość drogi CoP i współczynniki dynamiki nieliniowej: entropia próbkowa, wymiar fraktalny i wykładnik Lapunowa. Wykazano, że zmniejszenie pola powierzchni podparcia powoduje istotny wzrost współczynnika entropii próbkowej i wymiaru fraktalnego.
    The aim of the study was to assess postural stability under different base of support: both foot standing, one-leg standing and tandem with eyes open. A group of thirty-three healthy persons aged 21.88 ± 1.65 years participated in the study. The tests were carried out using the AMTI AccuSway platform. The locations of the center of foot pressure (CoP) in the X and Y planes were exported. Then the CoP path length and nonlinear dynamics coefficients were calculated: sample entropy, fractal dimension and Lapunov exponent. It has been shown that the reduction of the support surface area causes a significant increase in the sample entropy factor and the fractal dimension.

    Opis:
    The number of primary hip arthroplasties is growing every year. One of the most common long complications is the aseptic loosening of the prosthesis leading to serious complications in patients life, pain and following surgeries. In the literature, there is a lack of studies regarding balance impairment in this group of patients, which is why there was a need to conduct the study in order to find possible falling risk factors and simple functional, diagnostic test. The aim of the study was to assess functional state and static balance disorders in patients admitted to orthopaedic department due to loosened hip prosthesis prior to its replacement or removal. Methods: The study population were 30 patients (15 women and 15 men) admitted to Orthopaedic Department for diagnosis and treatment of loosened hip prosthesis. Patients’ mean age was 71.67 ± 9.21, body height 169.20 ± 8.75 cm, body weight 77.83 ± 12.96 kg. The clinical control group consisted of 30 healthy subjects age-, body height- and weight-matched, without degenerative disorders of lower extremities. Function was assessed with Harris Hip score. The static balance test was conducted in the mornings, in quiet separate room on bi-modular stabilometric platform CQStab2P, registering the movement of centre of foot pressure (COP). Results: Measurements with eyes open and closed showed significant differences in limb loads – the load to the healthy limb was several times greater. Results of tests on the platform with eyes closed showed significantly worse balance in patients group. Their total statokinesiogram path was longer, and their COP sways number was greater. Similarly to the test with eyes open, the load of the healthy limb was much greater. Conclusion: Hip replacement loosening results in significant worsening of balance parameters. Balance assessment could be an additional useful diagnostic tool for hip replacement loosening available for physiotherapists.

    Opis:
    The osteoarthritis of the hip dominant symptom is pain that leads to disability and to postural and gait disorders. The aim of this study was to analyze postural stability and its impact on disability and pain. The study population consisted of 60 patients and control group of 30. Group 1 (n = 30) included patients with unilateral coxarthrosis, aged 56.2 (±12.3) years, BMI 25.17 (±2.87) kg/m2. There were 16 men (53.3%). The mean age of patients in group 2 (n = 30) with bilateral coxarthrosis was 62.3 (±12.1) years; the mean BMI was 24.87 (±2.06) kg/m2. There were 15 men in this group (50%). The patients were evaluated using the WOMAC, the Harris Hip Score, VAS and the Biodex Balance System. Both study groups had stability index results different than the control group. There was a significant correlation between the stability indexes and BMI. VAS correlated with the M-L plane variance. In group 2, there were significant differences related to disability for the disability scales for all measured parameters. Balance disorder is a basic parameter found in coxathrosis. There is a statistically significant correlation between balance disorders and BMI, VAS and functional scales.

    Opis:
    Purpose: The aim of the study was to analyze postural stability in Parkinson's disease patients. A total of 32 subjects were tested, including 26 (81.25%) women and 6 (18.75%) men. These were patients with advanced, idiopathic Parkinson’s disease. The disease duration was over 5 years. Methods: The study was conducted in the Posturology Laboratory at the Department of Medicine and Health Sciences, Jan Kochanowski University in Kielce (Poland). The Biodex Balance System was used for evaluation of postural stability. Postural Stability Testing was performed with both feet positioned on a stable surface with the eyes open. Results: The Overall Stability Index in the whole group was 0.5°. The higher Overall Stability Index in women is indicative of slightly worse postural stability compared to men, although in both groups, it was within norms (Z = 2.0545, p = 0.0399). Anterior-Posterior Overall Stability Index (A/P) was an average of 0.35°. The Medial-Lateral Overall Stability Index (M/L) was an average of 0.27°. Both women and men were observed to have higher postural sway in the sagittal plane than the frontal plane. The vast majority of the subjects maintained in Zone A during testing (99.94%), and was slightly bent backwards to the right and in Quadrant IV (61.53%). Conclusions: Regular control of postural stability in Parkinson's disease patients is significant due to the risk of falls.

    Opis:
    Purpose: The purpose of this paper was an attempt to evaluate changes in the level of static equilibrium and the impact of visual information on the effectiveness of postural reactions of women in geriatric age. Methods: 36 senior female residents of L.A. Helc Nursing Home in Cracow, Poland, were examined. Considering the age, 2 groups were distinguished: group I – women at the age 71– 80 and group II – women aged 81–87. Their balance was assessed with stabilographic platform CQ Stab 2P. Measurements of the body stability were made in free standing position, with eyes open and eyes closed. Comparison of selected indicators of stability between the groups of the women was made with the Mann–Whitney U test. To assess the significance of differences between the results obtained in the test with eyes open and without visual control the Wilcoxon test was used. Results: Statistically significant differences between the results obtained in the groups concerned the length of the statokineziogram path on the X-axis, as well as the average speed of the COP movement on the X-axis. In the test without the visual control both groups showed statistically significant deterioration in most indicators of stability. Conclusions: Loss of postural control as a result of progressive involutional changes in the aging process is characterized by the intensity of the body instability in the frontal plane. These results indicate the need of applying in the rehabilitation programmes for elderly people adequate solutions, including the exercises directed at developing new or enhancing the decaying adjustment mechanisms.

    Opis:
    The purpose of this work was to assess the differences of the values of body posture indices, measured with the Moire’s method, between girls and boys aged 13 and the relationships of these values with the results of the Y-Balance Test. Methods: The study involved a group of healthy volunteers attending junior high schools in Cracow. The group consisted of 20 girls and 35 boys. Basic somatic parameters were measured within this work: body height and weight. Body posture was assessed according to the general methodology of the Moire’s technique and 14 body posture indices were obtained as a result: 6 in the sagittal plane, 1 in the axial plane and 7 in the coronal plane. Postural stability was assessed with the Y-Balance Test (YBT). Results: The studied girls and boys had practically the same body posture – statistical differences were found only in 3 out of 14 assessed indices measured with the Moire’s technique. Scoliosis was found in as many as 51% of the subjects, however, mean values of deviations from the C7-S1 line were not large. Conclusions: In the group of girls, the set of blades (below – above) was statistically significantly correlated with the global YBT result for the right inferior extremity, and in the group of boys – the set of the waist triangles (below – above) was statistically significantly correlated with the global YBT results for the right and left inferior extremities.

    Opis:
    The goal of this study was to quantify the effect of experience and handrail presence on trunk muscle activities, rotational spinal stiffness and postural stability of construction workers. We evaluated spinal stability, and objective and subjective postural stability in 4 expert and 4 novice construction workers who were performing a manual task in a standing position on a scaffold, with and without a safety handrail. Center of pressure was computed using measurements taken with insole pressure transducers. Muscle activity was monitored usingsurface electrodes placed on 8 trunk muscles that predicted active trunk rotational stiffness. Standard deviations of the center of pressure, back muscle activity and spinal stiffness were greater in novices and in the absence of a handrail. We infer that the risk of a fall due to postural and spinal instability may be greater with a lower level of experience and in the absence of a safety handrail.

    Opis:
    Purpose: Correct foot structure is important due to locomotion and postural stability. The aim of this study was to determine the relationships between morphological foot structure and balance indices in a quiet standing position in women over 65 years of age. Methods: The study included 116 women aged 65-90 years. The mean age was 70.6±8.4 years and BMI 29.1±3.4 m/kg2. The measured indices included postural control while standing on both feet and photogrammetric foot evaluation. An analysis was performed of the selected foot and balance indices. Results: There were no significant differences observed in the feet structure. Certain correlations between some foot indices and the indices of postural control were noted. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis. Conclusions: The differences between the indices and morphological indices for the right and the left foot are not significant, which indicates the proportionate formation of feet in the individual life. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis.

    Introduction: The upright posture uniquely characteristic of humans is dependent upon many factors. Kinesio Taping is used to enhance ankle joint stability, but its effectiveness in relation to body stability in a standing position has not yet been verified in scientific research. Objectives: Assessment of the effect of ankle Kinesio Taping on stabilometric parameters in young, healthy women. Material and Methods: The study included 50 healthy women (mean age 21.12 ±1.83 years) who were randomly assigned to two groups: the taping group (group T) and control group (group C). In the taping group Kinesio Taping was applied according to the method used in ankle sprains (both inversion and eversion). The women performed the Romberg test four times with each trial lasting two minutes on an Alfa AC International East stabilometric platform: two tests without Kinesio taping intervention and two further tests with (group T) or without taping (group C). Results: Significant differences between the groups were observed in the following parameters: mean speed in the sagittal plane with eyes open; 0.06 cm/s (p=0.0002), mean speed in the frontal plane with eyes open; 0.07 cm/s (p=0.0001), total path length with eyes open; 5.78 cm (p=0.0001) and sway area with eyes open; 0.58 cm2 (p=0.0002) and in parameters: mean velocity in the sagittal plane with eyes closed; 0.10 cm/s (p=0.0004), mean velocity in the frontal plane with eyes closed; 0.11 cm/s (p=0.0004) and in total path length with eyes closed; 0.43 cm (p=0.0004). Conclusions: In young, healthy women who received Kinesio Taping, favourable changes in stabilometric parameters were found indicating better ankle stability than in the group without taping.
    Wprowadzenie: Pionowa postawa ciała stanowi unikalną cechę człowieka, zależną od wielu czynników. Kinesiotaping jest stosowany w celu poprawy stabilności stawu skokowo-goleniowego, natomiast skuteczność takiej aplikacji, jak się wydaje w odniesieniu do stabilności ciała w pozycji stojącej nie została wystarczająco zweryfikowana w badaniach naukowych. Cele: Ocena wpływu kinesiotapingu stawu skokowo-goleniowego na parametry stabilometryczne u młodych, zdrowych kobiet. Materiał i Metody: W badaniu wzięło udział 50 zdrowych kobiet (średni wiek 21,12 ±1,83). Badane zostały losowo podzielone na dwie grupy: tejpowaną (grupa T) i kontrolną (grupa K). W grupie badanej wykonano aplikację kinesiotapingu w formie stosowanej po skręceniach stawu skokowo-goleniowego zarówno inwersyjnych, jak i ewersyjnych. Badane kobiety zostały poddane 4-krotnej próbie Romberga trwającej 2 minuty na platformie stabilometrycznej Alfa AC International East. Dwie próby przeprowadzono przed naklejeniem aplikacji kinesiotapingu i kolejno dwie próby: z plastrowaniem (grupa T) bądź bez oklejania (grupa K). Wyniki: Istotne statystycznie różnice pomiędzy grupami stwierdzono w parametrach: średnia prędkość ścieżki X przy oczach otwartych; 0,06 cm/s (p=0,0002), średnia prędkość Y przy oczach otwartych; 0,07 cm/s (p=0,0001), długość ścieżki przy oczach otwartych; 5,78 cm (p=0,0001) i pole powierzchni przy oczach otwartych; 0,58 cm2 (p=0,0002) oraz w parametrach: średnia prędkość X przy oczach zamkniętych; 0,10 cm/s (p=0,0004), średnia prędkość Y przy oczach zamkniętych; 0,11 cm/s (p=0,0004) oraz w długości ścieżki przy oczach zamkniętych; 0,43 cm (p=0,0004). Wnioski: U młodych, zdrowych kobiet poddanych aplikacji kinesiotapingu stwierdzono korzystną zmianę parametrów stabilometrycznych wskazującą na większą stabilność stawu skokowo-goleniowego w porównaniu do grupy, u której metoda ta nie była stosowana.

    Opis:
    The purpose of this study was to assess if 65 dB and 4000 Hz stimuli affect postural stability of young normal hearing people. Methods: Posturography examinations belong to clinical tests which evaluate the motor skills. Posturography can be divided into static posturography and dynamic posturography. In both, static posturography and dynamic posturography, patient stays on the platform with opened and closed eyes, but in the case of dynamic one, platform is unstable. In this study the Multitest Equilibre platform produced by FRAMIRAL was used. Patients took part in tests with opened and closed eyes, on stable and unstable platform. Additionally patients were exposed to 65 dB and 4000 Hz acoustic stimuli. The sound pressure level, and frequency was belonging to the best audibly frequency range. Results: Parameters such as velocity and surface were examined. The difference between velocity measured with acoustic stimuli and without acoustic stimuli was observed. On the other hand there was no difference in surface results. Conclusions: The statistically significant difference between velocity of patients center of gravity movements, measured on unstable platform, in the presence of 4000 Hz, 65 dB acoustic stimulus and without additional disturbances was observed.

    Wstęp. W pracy dokonano ilościowej analizy wpływu wskaźnika BMI na stabilność posturalną kobiet w okresie wczesnej starości. Materiał i metody. Badania przeprowadzono w grupie 41 kobiet w wieku 60-74 lata. Stabilność posturalną kobiet oceniano za pomocą komputerowej dynamicznej posturografii (CDP). Oceniano użyteczność sygnałów pochodzących z narządów zmysłów biorących udział w kontroli równowagi ciała oraz prawidłowość doboru odpowiedniej strategii motorycznej. Określano wychylenia środka ciężkości ciała w kierunku przednio-tylnym i łączny wynik analizy równowagi ciała. Wyniki. W wyniku przeprowadzonych badań stwierdzono ujemną korelację wskaźnika BMI badanych kobiet z wynikami analizy równowagi oraz wynikami analizy strategii motorycznej. Wnioski. Wraz ze wzrastającą wartością wskaźnika BMI zwiększa się zakres wychwiań środka ciężkości kobiet w kierunku przednio–tylnym. U osób z nadwagą stwierdzono gorsze wykorzystanie informacji somatosensorycznych i strategię stawu biodrowego. Otrzymane ilościowe zależności pomiędzy parametrami układu równowagi ciała ocenianymi w badaniu CDP a BMI wskazują na niekorzystny wpływ nadwagi i otyłości na stabilność posturalną kobiet w okresie wczesnej starości.
    Introduction. In this study, a quantitative analysis of the BMI index on the postural stability of women in early old age was conducted. Materials and methods. The study was conducted in a group of 41 women aged 60-74. The postural stability of women was assessed using computerized dynamic posturography (CDP). The usefulness of signals coming from sensory organs involved in the control of the body’s balance and the correctness of choosing the appropriate motor strategy were assessed. The deflections of the centre of gravity of the body in the anteroposterior direction and the combined result of body balance analysis were determined. Results. As a result of the conducted research, a negative correlation between the BMI index of the studied women and the results of the balance analysis, as well as the results of the motor strategy analysis was found. Conclusions. Along with the increase in the BMI index, there increases the range of deflections of women’s centre of gravity in the anteroposterior direction. In overweight people, worse use of somatosensory information and hip joint strategy was found. The obtained quantitative relationships between the parameters of the body balance system assessed in the CDP examination and BMI indicate the adverse effect of excessive weight and obesity on the postural stability of women in early old age.

    Opis:
    Celem pracy była ocena stabilności ciała i jej mechanicznej kontroli przy staniu swobodnym na boso i staniu w ortozach kończyn dolnych u dzieci z mózgowym porażeniem dziecięcym. Badaniami objęto 40 dzieci z mózgowym porażeniem dziecięcym (MPDz) - pacjentów Mazowieckiego Centrum Neuropsychiartii w Zagórzu koło Warszawy. Grupę badawczą podzielono na dwie podgrupy ze względu na postać kliniczną MPDz: 20 osób z niedowładem połowiczym i 20 osób z niedowładem obustronnym. Wiek badanych mieścił się w przedziale 2-15 lat. Do oceny stabilności ciała i jej mechanicznej kontroli wykorzystano metodę stabilograficzną przy użyciu sprzętu AMTI NetForce OR6-7-1000. Pomiar równowagi przeprowadzono w dwóch pozycjach: stojącej swobodnie na boso i stojącej swobodnie w ortozach kończyn dolnych. Wyniki badań wskazują, że do poprawy stabilności ciała w pozycji stojącej po założeniu ortoz kończyn dolnych dochodzi w obu grupach badawczych, co objawia się zmniejszeniem wartości parametrów stabilograficznych. Istotne zmiany wykazano jedynie w grupie dzieci z niedowładem połowiczym, w zakresie: przemieszczenia COP lewo-prawo, średniej prędkości oraz długości całkowitej stabilogramu.
    The aim of the work was the evaluation of differences in the postural stability and its mechanical control between free bare feet standing position and standing position in lower limbs’ orthoses of children suffering from cerebral palsy. The examination included 40 children with cerebral palsy from Mazowieckie Centre of Neuropsychiatry in Zagórze, near Warsaw. The research group was divided into two subgroups: 20 persons with hemiparesis and 20 with diparesis. The examined children were aged between 2-15. The examination of body stability and its mechanical control was carried on with the help of the stabilographic method by means of AMTI NetForce OR6-7-1000 equipment. Balance was measured in these two tests: free standing, bare feet and standing with orthotics of lower limbs. An improvement in terms of lowering the values of stabilographic parameters of the body stability in both research groups after using lower limbs’ orthotics, was stated. Significant changes were observed only in the group of children with hemiparesis in the range of: left-right COP movement, mean speed and length of stabilogram.
