Purpose: The paper aimed to assess the gait pattern in children and adolescents with juvenile idiopathic arthritis (JIA) treated at the rehabilitation center and to assess changes in this pattern after the end of treatment and 9 months later. Methods: 50 children with JIA were enrolled into the study. 35 healthy volunteers were enrolled into the study for a comparison. Spatiotemporal and kinematic gait parameters were obtained using a movement analysis system. The Gait Deviation Index (GDI) was calculated. The assessment was performed three times: on the day of admission to the rehabilitation center, after the end of a 4-week treatment period and 9 months later. Results: With regard to the majority of spatiotemporal and kinematic parameters, differences in their distribution were highly statistically significant between the study group and the control group (p < 0.001). In two subsequent tests, differences were less significant when compared to the control group (p < 0.01). In the study group, ranges of motion in the sagittal plane in the hip (p < 0.01), knee (p < 0.001) and ankle joints (p < 0.01) increased significantly between tests 1 and 2, and 1 and 3. A significantly lower value of GDI was observed in the study group (right limb; p = 0.036). Conclusions: The gait pattern of children with JIA is significantly different from the one observed in healthy children. A rehabilitation program significantly improved gait in children with JIA, but differences compared to healthy children were still observed, and it indicates that the abnormal gait pattern became permanent in this group of subjects.

SummaryStudy aim: the aim of the study was to compare the postural stability and ability to control balance in active women who attend fitness classes versus inactive women. Material and methods: the study included 41 women who exercise regularly (mean age 28.64±5.26 years). The control group consisted of 42 women not engaged in regular physical activity (mean age 28.55±5.05 years). In each subject, postural stability testing was performed using the Stabilometric Platform CQStab2P (the 2-platform version). Authors analysed the mean, median and standard deviation for each parameter of the stabilogram and statokinesiogram. Results: for most of the studied parameters, the statistical analysis showed a positive effect of exercising on the level of fitness compared to the control group, for both the test with eyes open and the test with eyes closed. Conclusions: attending fitness classes significantly affects postural stability and balance control in young women, and leads to lesser dependence on sight to maintain it.

Introduction. Endoprosthetics is currently most common method of the treatment of advanced osteoarthritis, including knee joint osteoarthritis. Its main goal is to restore patients functional independence in activities of daily living through reducing pain and disability. Objective. The aim of this study was functional assessment of the patients after total knee replacement (TKR) considering subjects age and gender, BMI and mean duration of the disease. Material and methods. 70 patients (59 females and 11 males), qualified for total knee replacement surgery due to the primary knee osteoarthritis (KO), participated in this study. Mean age of the patients in the study group was STRESZCZENIE Wstęp. Endoprotezoplastyka jest obecnie najbardziej rozpowszechnioną metodą leczenia zaawansowanych zmian zwyrodnieniowych stawów, w tym stawu kolanowego. Jej głównym celem jest przywrócenie funkcjonalnej niezależności pacjentów w czynnościach dnia codziennego poprzez zmniejszenie natężenia bólu i niepełnosprawności. Cel pracy. Ocena funkcjonalna pacjentów po całkowitej endoprotezoplastyce stawu kolanowego z uwzględnieniem płci, wieku, BMI oraz czasu trwania choroby. Materiał i metoda. W badaniu udział wzięło 70 pacjentów (59 kobiet, 11 mężczyzn), którzy zostali zakwalifikowani do zabiegu całkowitej endoprotezoplastyki stawu kolanowego w wyniku pierwotnych zmian zwyrodnieniowych.
