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:
Maintaining the body underwater in the so-called vertical position, where the body is inverted (head down) and balanced, is made possible by performing the support scull movement by the upper limbs. In synchronized swimming, the main criteria for judging this vertical position are maintaining body stability and the maximum height of the lower limbs one is able to extend out of the water. Therefore, it seems important to examine for any correlations between the symmetry of the upper limb’s movement (sculling) and the ability to maintain balance of the body. The aim of this study was to use a dynamical asymmetry index (DAI) to assess the symmetry of the upper limb movements performed in synchronized swimming. The use of the dynamical asymmetry index is considered to be advantageous over the asymmetry coefficient, which is better known in literature on the subject and has been used by numerous authors, as it not only evaluates the magnitude of the asymmetry, but also indicates in which phases of movement asymmetry is the greatest or where it is the least significant.

Opis:
The aim of the study was to compare the values of selected stability indices registered in the trials in standing with eyes open and without visual control, and in handstand in athletes practicing artistic gymnastics at the highest level of advancement. Methods: The study included 20 athletes practicing artistic gymnastics. The research tool was posturograph CQ-Stab 2P. The results obtained in individual trials were compared using Friedman repeated measures analysis of variance by ranks and then subjected to Dunn post-hoc test with Bonferroni adjustment. Results: Statistically significant differences in the values of stability indices recorded in individual samples were found. Exceptions are the results obtained in the trials with eyes open and without visual control with regard to the size of the surface area delineated by the COP ( p = 0.173) and the frequency of corrective reactions ( p = 0.464), as well as the length of the statokinesiogram path in the mediolateral direction ( p = 0.342), mean velocity of COP movement in the mediolateral direction ( p = 0.246), maximal amplitude of the COP in the mediolateral direction ( p = 0.342) and number of COP displacements in the mediolateral direction ( p = 0.246). Conclusions: In seniors, disabling visual control during free standing as well as adopting a handstand position result in deterioration of the stability indices, which is a resultant of the COP displacement in both directions as well as in the anteroposterior direction. Lack of differences in the values of stability indices in the mediolateral direction suggest that in a free standing position, seniors practicing artistic gymnastics control the movement of the center of foot pressure in the mediolateral direction and eye control is not important for the stability of the body in the frontal plane.

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.

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 aim of this study was to compare gait stability and variability between walking conditions and age groups. Methods: Twenty-six healthy younger and older females participated. Trunk acceleration in the vertical (V), medial-lateral (ML) and anteriorposterior (AP) directions during 5 minutes walking overground and 3 minutes walking on the treadmill at self-selected speed were recorded. Root mean square and standard deviations of acceleration, stride time and its variability, Lyapunov exponents (LE), multiscale entropy (MSE) and harmonic ratios (HR) were computed. Results: Both age groups showed significantly higher stride time variability and short-term LE in all directions during overground walking. For the older group, overground walking showed higher V and AP standard deviation. Significantly lower values for overground walking were observed for long-term LE (V and ML for the younger group, ML for the older group), HR (ML for the older group) and MSE (V for the older group). Significant age-related differences were found for V long-term LE for overground walking. Conclusions: The present findings suggest that both linear and advanced computational techniques for gait stability and variability assessment in older adults are sensitive to walking conditions.

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 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.

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:
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.

Purpose: It is still not clear which parameters of sound are the most significant for body reactions and whether the way of sound reception plays a role in body control. The purpose of this study was to determine the influence of frequency, spectrum and loudness of sounds on posture control in healthy women and men. Methods: The study subjects were 29 young adults who were submitted to a 60-second standing test in the bipedal stance on the force platform (AMTI). During the tests, 3 sinusoidal sounds with various timing and 2 musical sounds (guitar and piano) of the frequency 225 Hz, 1000 Hz and 4000 Hz were applied through headphones. The centre of pressure (COP) amplitude was registered. The sway area and COP mean velocity were computed. Results: It was found that high frequency sounds contributed to a significant decrease of sway area values. No significant influence of low frequency sounds on posture control was observed. The influence of the sound spectrum (timbre) on posture control is limited; only the crescendo spectrum improves the body stability in the bipedal stance and not the music spectrum as guitar and piano. The loudness of sound, although extremely high, is not the cause of postural control changing in relation to lower loudness. No effect of gender was found in terms of body stability under different sound conditions. Conclusion. Based on the results, it can be argued that, in general, in a bipedal stance in terms of stability high sound frequency improves posture control, whereas sound spectrum and intensity show a limited impact.

Opis:
The present study aimed at investigating the control of upright quiet standing in pregnant women throughout pregnancy, and whether low-back pain exerts influence on this motor task. Methods: Myoelectric signals from postural muscles and stabilometric data were collected from 15 non-pregnant and 15 pregnant women during upright quiet standing. Electromyogram envelopes and center of pressure metrics were evaluated in the control group, as well as in pregnant women in their first and third trimester of pregnancy. A correlation analysis was performed between the measured variables and a low-back pain disability index. Results: Pregnant women exhibited a decreased maximum voluntary isometric activity for all postural muscles evaluated. Additionally, the activity of lumbar muscles during the postural task was significantly higher in the pregnant women in comparison to the non-pregnant controls. The soleus muscle maintained its activity at the same level as the gestation progressed. Higher postural oscillations were observed in the anteroposterior direction while mediolateral sway was reduced in the third trimester of pregnancy. No correlation was detected between the lowback pain disability index and neuromechanical variables. Conclusion: This study provides additional data regarding the functioning and adaptations of the postural control system during pregnancy. Also, we provide further evidence that postural control during quiet standing cannot be used to predict the occurrence of low-back pain. We hypothesize that the modifications in the neural drive to the muscles, as well as in postural sway may be related to changes in the biomechanics and hormonal levels experienced by the pregnant women.

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:
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:
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.
