Introduction The purpose of the study was to assess the functional abilities of patients after stroke and to identify factors that affect it. Material and methods The study was performed on 40 patients after stroke. To assess functional ability the Rivermead Motor Assessment (RMA), Barthel Index (BI), Tinetti test, and Up&Go test were used. The maximum muscle power (Pmax), optimal shortening velocity (Vopt), muscle strength, one-leg standing test, Geriatric Depression Scale (GDS), pain assessment (Numeric Pain Scale), nutrition assessment (Mini Nutritional Assessment Scale - MNA) were also performed. Results Functional performance was influenced by: knee flexors on the affected side (correlations respectively: RMA rho=0,37; p=0,04; Tinetti test rho=0,44; p<0,01; Up&Go test rho=-0,56; p<0,001), balance time on a non-affected leg (RMA rho=0,38; p=0,03; BI rho=0,41; p=0,01; test Tinetti rho=0,64; p<0.001; Up&Go test rho=-0.47; p=0.003), Pmax (RMA rho=0,35; p=0,04; Tinetti test rho=0,49; p<0,01; Up&Go test rho=-0,63; p<0.001), reporting problems with sitting and standing up (RMA p=0,003; Tinetti test p=0,02; Up&Go test p=0.049), using orthopedic assistance (RMA global functions p=0,01; RMA lower limb and torso p=0,04; BI p=0,003; Tinetti test p<0,001, Up&Go test p<0,001). The MNA result was correlated with RMA (rho=0,36; p ,0.04), no correlation was obtained for any of the functional tests with the extensor muscle strength on the non-affected side, GDS and pain level. Conclusions The functional ability of stroke patients is affected by knee flexors on the affected side, the ability to maintain balance, and maximum muscle power. People, who reported problems with sitting and standing up and using orthopedic assistance, are characterized by worse ability.

Introduction The purpose of the study was to assess the occurrence of deficits in strength and power of lower limb muscles and functional performance of patients with back pain syndromes and to identify the factors that affect them. Material and methods The clinical material consisted of 43 patients (28 women with back pain syndrome, the control group - 15 people). Up & go test, Barthel Index, five - time standing up test, Tinetti test, assessment of power (Pmax), strength and optimal shortening velocity (Vopt), Geriatric Depression Scale (GDS), pain assessment were performed in all patients. Results The patients from the control group achieved better results in the five - time standing - up test (p = 0,006), in the Tinetti test (p = 0,04) and had higher knee extensors muscle strength (p = 0,005). Functional performance in patients with lumbosacral spine pain syndromes was determined by the strength of the knee extensors muscles (Up & go test Rho = 0,54; p = 0,005; five - time standing up test Rho = 0,39; p = 0,04; Tinetti for gait Rho = 0,4; p = 0,04). Age and height influenced the parameters of muscle function. Conclusions Patients with back pain syndromes are characterized by reduced functional performance and have knee extensors muscle deficit in relation to people without back pain. Knee extensors muscle strength has the greatest impact on functional performance in patients with back pain. Younger and taller people have better results in muscle function tests.
