[Muscle parameters in coxarthrosis].
The aim of this study was to investigate the muscular condition around the hip joint in osteoarthritis (grades of reduction of motion range and muscle strength). We analyzed a group of 64 patients with diseased hips and definite clinical and radiological signs of degenerative hip alterations. The control group consisted of 32 persons with healthy hips who matched the examined group by age and sex. All subjects underwent the quantitative assessment of hip motion range and muscle strength. The study of comparative kineziometric parameters showed a decreased muscle function of all examined hip motions for all measured parameters, being the most distinctive in case of medial rotation of hip (73.48%). Mean values of muscle strength were also decreased in all examined muscles. The biggest value decrease was registered for abductors (musculus gluteus medius). In comparison with the control group results it was a decrease of 55.30%. The results we obtained in our study indicated the reduction of muscle performance in patients with osteoarthritic hips.
