Opis:: It was explored whether three different applications of elastic tape on the lower limbs of active, healthy dancers influence their postural control performance. 15 active, healthy dancers randomly performed demi-pointes and sissone ouvertes on a force platform in four experimental conditions: 1. no tape application, 2. ankle joint tape application, 3. leg muscle tape application, and 4. control tape application. Four kinetic parameters were calculated in order to represent postural control performance: 1) variable error of force magnitude in forward-backward direction, 2) variable error of force magnitude in side to side direction. 3) peak impact force during landing phase and 4) episodes of overall duration. Results revealed a task-dependent performance-enhancing effect and an application-specific performance-influencing effect concerning vertical ground reaction force measurements. It is concluded that the application of elastic tape for healthy, active dancers may on the one hand enhance parameters of postural control, whereas the same elastic tape application may hamper other performance related aspects of typical modern and classical ballet dance routines. Conflicting scientific results may thus indicate that generalized effects are controversial and positive influences in one specific characteristic can induce a decrease in another performance influencing characteristic.

Opis:: The aim of the research was to assess the postural stability indicators of older women and men receiving institutional care. Methods: The study involved 123 people aged 65–85, living in residential care homes in Rzeszów district. The main research tool was the CQ-Stab 2P 2-platform posturograph. Results: There were statistically significant differences between women and men in the total statokinesiogram path length, the statokinesiogram path length in the anteroposterior direction, the mean COP displacement in the anteroposterior direction as well as the mean velocity of the COP point in the anteroposterior direction under eye control ( p = 0.04). In the case of absence of visual control, men were characterized by significantly worse parameters in the area of mean COP displacement in the anteroposterior and lateral directions as well as the maximal COP displacement in the anteroposterior and lateral directions. It indicated that without visual control body balance parameters in men significantly worsened along with increasing age. A statistically significant difference was found between both genders in terms of the statokinesiogram path length, the mean COP displacement and the mean COP velocity ( p < 0.05). Conclusions: Gender differences in postural stability of older people under institutional care were noticed. Men were characterized by a lower level of postural stability compared to women. Elimination of visual control significantly worsened the balance of the body. The results obtained indicate the necessity of introducing therapeutic programs in nursing homes, taking proprioceptive exercises and exercises without visual input into account.

Opis:: Purpose: The aim of the study was to determine whether 10- to 13-year-old, national-level, female acrobatic gymnasts present a different quiet standing postural control (with and without visual cues) than untrained female peers. Methods: The mean velocity of the center of pressure (in anterior-posterior and medial-lateral directions) was computed from 60-s long quiet-standing trials on a stationary force plate in fifteen 10- to 13-year-old female acrobatic gymnasts and thirteen sex- and age-matched non-athletes. A two-way repeated measures ANOVA (acrobatic gymnasts vs. non-athletes and eyes open vs. eyes closed) was used for the anterior-posterior and mediallateral COP mean velocity. The relation between subjects’ body mass and COP mean velocity was tested with the used Spearman’s Rank Correlation Coefficient. Results: Postural sway (represented by COP mean velocity) was not significantly different between the acrobatic gymnasts and the non-athletes ( p > 0.05), except for the faster medial-lateral sway in eyes-open conditions in the acrobatic gymnasts ( p < 0.05). The gymnasts’ body mass negatively correlated with their anterior-posterior sway velocity in both visual conditions (eyes open: r = –0.7; eyes closed: r = –0.6) and with medial-lateral sway velocity during eyes-closed trials (r = –0.5; p < 0.05). Conclusions: Results of the study indicate that in quiet standing postural control 10- to 13-year-old acrobatic gymnasts did not make use of their trained abilities. Heavier gymnasts might have been more stable than lighter ones during quiet standing.

Opis:: Purpose: Presentation of the results of clinical study on new supplementary method applied in the physical rehabilitation of patients who underwent total hip arthroplasty. The standard rehabilitation program was supplemented with the lower limb loading symmetry training based on the follow-up posturography with an adaptively modified visual biofeedback, performed on a double plate posturographic platform. Methods: The research involved 60 randomly selected patients included in prospective and comparative clinical study in the scheme of the parallel groups. The subjects were divided into two groups comprised of 30 patients each. In both groups a conventional 21-day rehabilitation was carried out. Additionally, in experimental group the limb loading symmetry restoration training based on the follow-up posturography with an adaptively modified biofeedback was implemented. The biofeedback coefficient reflected the distribution of loading exerted on a given patient’s legs and was evaluated during the static posturography examinations carried out before each symmetry training session. Results: The eyes-open static posturography examinations indicated significant improvement in the lower limb loading symmetry in 29 (97%) patients from the experimental group ( p = 0.000003). In the control group, such an improvement was observed in 20 (67%) patients ( p = 0.034796). In the eyes closed examinations correction in the limb loading symmetry was evident in 23 (77%) patients from the experimental group ( p = 0.000247) and 18 (60%) patients from the control group ( p = 0.043327). Conclusions: Significant improvement in the lower limb loading symmetry was observed in patients who underwent rehabilitation supplemented with the herein discussed training method.

Opis:: Introduction: The authors present the influence of two physiotherapy programmes on the re-education of motor behaviour in patients after ischemic stroke. One of them is a programme based on exercises combining PNF and NTD Bobath elements, while the other is a deep trunk muscle exercises with the use of the PUM armchair. Material and methods: The study material was a group of 60 patients of both sexes who suffered ischemic stroke resulting in hemiparesis. They were divided into two groups. Group I consisted of 18 women (60%) and 12 men (40%) who followed the author’s programme of deep muscle activation exercises using the PUM armchair. Group II consisting of 15 women (50%) and 15 men (50%) followed the exercise programme using standard methods, i.e. based on PNF and Bobath methods. Results: They indicate the effectiveness of both methods, with the predominance of the author’s programme. Conclusion: The improvement of deep muscle activity in the examined group of patients has positive influence on their muscle tone, balance and postural control, which in turn, reduces muscle tension, improves gait stereotype and load characteristics of lower limbs. ischemic stroke, postural control, deep muscles Article received: 30.01.2018; Accepted: 30.03.2018

Opis:: Wstęp. Piłkarze nożni narażeni są na częste urazy supinacyjne stawu skokowo-goleniowego, który, wielokrotnie powtarzany, sprzyja powstaniu przewlekłej niestabilności (CAI). Dotychczasowe badania wskazują, iż CAI nie wpływa istotnie na stabilność posturalną w warunkach statycznych, jednakże istnieją przypuszczenia, że w warunkach dynamicznych może mieć istotne znaczenie. Z tego powodu celem naszych badań była analiza stabilności posturalnej w warunkach dynamicznych, z uwzględnieniem dominacji kończyny dolnej. Materiał i metody. W badaniu wzięło udział 28 piłkarzy nożnych (w wieku 26,1±5,4) zakwalifikowanych do grupy CAI zgodnie z kryteriami kwalifikacji International Ankle Consortium oraz 37 piłkarzy (w wieku 27,3±5,2), bez wcześniejszej historii urazu supinacyjnego, tworzących grupę kontrolną (CTRL). Do oceny stabilności posturalnej w pozycji stania obunóż oraz jednonóż w warunkach dynamicznych wykorzystano platformę Biodex Balance System. Wyniki. W postawie obunóż zaobserwowano różnice istotne statystycznie (p<0,05) między grupami CAI (OSI 7,01±2,43; APSI 5,18±1,85) i CTRL (OSI 5,27±1,42; APSI 3,98± 1,42). W postawie jednonóż zauważono podobne trendy, gdzie CAI uzyskała istotnie statystycznie (p<0,05) wyższe wyniki w analizowanych parametrach. Funkcja kończyny dolnej odgrywała istotną rolę w grupie CTRL w parametrach OSI (dom. 7,23±1,48; n-dom. 5,64±1,51) oraz MLSI (dom. 3,8±0,64; n-dom. 3.07±0,97). Wnioski. CAI upośledza stabilność posturalną u piłkarzy nożnych w warunkach dynamicznych zarówno w postawie obunóż, jak i jednonóż, jednakże funkcja kończyny dolnej istotnie wpływa na kontrolę posturalną jedynie w grupie CTRL.
Background. Football players are exposed to frequent supination injuries of the talocrural joint and repeated injuries lead to chronic ankle instability (CAI). Previous study results indicate that CAI do not significantly affect postural stability under static conditions, however, it is suspected that it may aggravate under dynamic conditions. Therefore, the goal of this study was analysis of postural stability under dynamic conditions with regard to dominance of the lower limb. Material and methods. The sample comprised 28 football players (age = 26.1±5.4), included in CAI group according to the Ankle Consortium inclusion criteria and 37 football players (age = 27.3±5.2) with no history of supination injuries, included in the control group (CTRL). Biodex Balance System platform was used for postural stability assessment during single leg standing under dynamic conditions. Results. During single leg standing statistically significant between-group differences were noted (p<0.05). The following values were obtained in CAI and CTRL groups respectively: CAI: (OSI 7.01±2.43; APSI 5.18±1.85), CTRL: (OSI 5.27±1.42; APSI 3.98±1.42). During single leg standing similar trends were observed. CAI group obtained statistically significant (p<0.05), higher values of the studied parameters. Lower limb function played an important role in CTRL group as for OSI (dom. 7.23±1.48; n-dom. 5.64±1.51) and MLSI (dom. 3.8±0.64; n-dom. 3.07±0.97) parameters. Conclusions. CAI impairs postural stability in footballers under dynamic conditions, both during single and double leg standing, however, the lower limb function significantly affects postural control only in CTRL group.

Opis:: This study aimed to determine the characteristic features of handstand posture control associated with a high level of ability among male gymnasts. Methods: 8 acrobatic gymnasts (4 more and 4 less experienced) participated in the study. They performed a 10-second handstand five times with each hand positioned on one AccuSway (AMTI) force platform and the other hand on the second. Body sway changes were recorded in time series: centre of pressure (COP) and components of the ground reaction force (GRF) (vertical, medial-lateral and anterior-posterior). The COP amplitude and average of GRF components, the index of frequency (by Fast Fourier Transform) for the right and left hand were calculated. Results: More experienced gymnasts performing a handstand concentrate mainly on minimizing anterior-posterior body sway with minimum medial-lateral body sway. Less experienced gymnasts’ pressure exerted on a surface by the hands is irregular in a medial-lateral direction. More experienced gymnasts control body position in the handstand and show less variation of body sway compared to less experienced gymnasts. More experienced gymnasts revealed lower frequency of body sway in the handstand compared to less experienced gymnasts. Conclusion: The stabilometric profile of more experienced gymnasts means the better posture control in handstand. The minimizing of body sway is compensated by exerting more force on a floor surface and the less experienced athletes cannot do that even after several years of training. The gymnasts of both groups, during standing on their hands, put more load on the right hand.

Opis:: Yoga is known as a type of exercise that combines physical, mental and spiritual aspects. There has not been much research on the postural control in various yoga poses. The aim of this study was to examine CoP regularity in both yoga instructors and novices during the performance of four yoga poses, and to verify the sensitivity of linear and nonlinear methods for assessing postural stability. Methods: The dynamic characteristics of CoP fluctuations were examined using linear and nonlinear methods on a group of 22 yoga instructors (Y) and 18 age-matched non-practitioners of yoga (NY). The study involved maintaining a balance for 20 seconds while performing four yoga poses. Results: Conventional analysis of CoP trajectories showed that NY and Y exhibited similar control of postural sway, as indicated by similar CoP path-length and area values observed in both groups. These results suggest that the special balance yoga training received by Y may not have an impact on less challenging balance conditions, such as the poses used in this experiment. Interestingly, nonlinear dynamical analysis of CoP showed that Y exhibited less CoP regularity and more complex signal than NY, as evidenced by higher values of sample entropy and fractal dimension. Conclusions: The results shed light on the surplus values of CoP trajectories in the nonlinear dynamical analysis to gain further insight into the mechanisms involved in posture control.

Opis:: Chronic ankle instability (CAI) is a common sequence of ankle sprain. Conservative treatment of CAI is currently accepted as a primary mean of managing the condition and preventing of recurrence. Objectives: The purpose of the current study was to evaluate the effect of Weight-bearing Exercise for Better Balance (WEBB) program and unilateral balance training exercises on postural control in females with CAI. Methods: Thirty-five females with CAI participated in this study. The participants’ mean values of age, body mass, height, and body mass index were 21.76 ± 1.96 y, 64.82 ± 9.37 kg, 161.85 ± 7.24 cm, and 24.76 ± 3.76 kg/m², respectively. They were randomly assigned into three groups: experimental group A (n = 13) who received WEBB program, experimental group B (n = 12) who received unilateral balance training, and control group C (n = 10) using statistical random tables. Balance parameters were measured for all participants via Biodex Balance System (BBS) before and after four weeks of balance training. They included overall stability index (OASI), antero-posterior stability index (APSI), and medio-lateral stability index (MLSI). Results: There was a significant improvement in the post testing mean values of OASI and APSI, compared with the pre testing values in both experimental groups (A and B). There was no significant difference between the pre and post testing mean values of MLSI in the experimental group (A). Conclusions: Both WEBB program and unilateral balance training have positive effects on postural control in females with CAI.

Opis:: Properties of supporting surfaces of a seat have an influence on postural control. Centre of pressure (COP) displacement parameters reflect both the balance controlling process and movements of the centre of a mass of entire body. The subjects of the study were 9 healthy men. A seat cushion was examined with a 2-force platform setup. Force exertion at a seat pan and feet and COP displacement at a seat pan were measured to analyse postural control. Analysis of variance determined the differences in postural control depending on a cushion type among the subjects. Significant differences in COP displacement parameters were in COP trajectory length, medio-lateral COP displacement and COP velocity. The results of the study showed that foam cushion ensures better postural control.
