    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:
    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:
    Introduction: Postural instability in patients with Parkinson’s disease (PD) is one of the major factors contributing to an increasing number of falls and fall related complications. Diagnosis of balance disorder is based on assessment of postural control by the biomechanical assessment of the musculoskeletal system, coordinating speed and precision of movements. The condition for the performance of precise and smooth movement is coordination of motor activity and sensory signals fl owing to the motor system. Study aim: The aim of the study is to assess the impact of non-motor symptoms (depression and cognitive impairment) and the impact of the severity of motor symptoms on the process of course of movement planning and control in Parkinson’s disease. Material and methods: The study involved 40 patients with idiopathic Parkinson’s disease, diagnosed according to the criteria adopted by the United Kingdom Parkinson’s Disease Society Brain Bank (UKPDSBB), with stage II or III severity of symptoms of the disease according to the Hoehn-Yahr sclae. All the patients underwent physical examination with an evaluation using the UPDRS (Unifi ed Parkinson’s Disease Rating Scale) and screening clinical trials were performed, evaluating cognitive functions (Montreal Cognitive Assessment, MoCA) and depressive disorders (Beck Depression Inventory, BDI). Evaluation of mobility, stability and motor control was done using the Berg Balance Scale (BBS), the Tinetti test, the Up and Go test (TUG) and the Dynamic Gait Index (DGI). Results: There was a signifi cant correlation between the level of severity of movement disorders (according to UPRDS ON part III) and the parameters defi ning motor skills in the DGI (R= -0.49, p<0.001), the TUG test evaluating mobility (R=0.4, p<0.01), and static and dynamic balance disorder using BBS (R=-0.44, p<0.004). The level of cognitive functioning had signifi cant impact on the mobility and stability of patients, and the occurrence of depressive disorder did not affect the deterioration of basic postural reactions in the group of patients with PD.

    Wstęp: Niestabilność posturalna u osób z chorobą Parkinsona (PD) jest jednym z głównych czynników przyczyniających się do zwiększenia upadków i związanych z nimi powikłań. Diagnostyka zaburzeń równowagi opiera się na ocenie kontroli postawy przez ocenę biomechaniczną narządu ruchu, koordynującą szybkość i precyzję wykonywanych ruchów. Warunkiem wykonania precyzyjnego i płynnego ruchu jest skoordynowanie czynności ruchowych oraz bodźców czuciowych z sygnałami płynącymi do układu ruchowego. Cel pracy: Ocena wpływu zaburzeń pozaruchowych (depresji i zaburzeń poznawczych) oraz nasilenia objawów ruchowych na proces planowania i kontroli przebiegu ruchu w chorobie Parkinsona. Materiał i metody: Do badania zakwalifikowano 40 chorych z idiopatyczną chorobą Parkinsona, rozpoznaną zgodnie z kryteriami United Kingdom Parkinson’s Disease Society Brain Bank (UKPDSBB), w stadium II lub III zaawansowania objawów choroby wg Hoehn-Yahra. U wszystkich chorych przeprowadzono badanie fizykalne wraz z oceną w skali UPDRS (Unified Parkinson’s Disease Rating Scale) oraz wykonano przesiewowe testy kliniczne, oceniające funkcje poznawcze (Montreal Cognitive Assessment, MoCA) i zaburzenia depresyjne (Beck Depression Inventory, BDI). Oceny mobilności, stabilności i kontroli ruchu dokonano za pomocą testów: Berg Balance Scale (BBS), testu Tinetti, testu Up and Go (TUG), Dynamic Gait Index (DGI). Wyniki: Wykazano istotną zależność pomiędzy poziomem nasilenia zaburzeń ruchowych (wg UPRDS ON cz. III) a parametrami definiującymi zdolności motoryczne w DGI (R= -0,49, p<0,001), testem oceny mobilności TUG (R=0,4, p<0,01) oraz zaburzeniami równowagi statycznej i dynamicznej w BBS (R=-0, 44, p<0,004). Poziom funkcjonowania poznawczego miał istotny wpływ na mobilność i stabilność chorych, a występowanie zaburzeń depresyjnych nie wpływało na pogorszenie podstawowych reakcji posturalnych w badanej grupie chorych z PD.
