A dynamometer for measuring the strength of the femoral muscles (crus and femur flexors and extensors) was developed. Dynamometric parameters of femoral muscles in the norm and their dependence on age (7-40 years old) were determined. Two working modes of the muscles of the hip joint in patients with ankylosis were highlighted. The pathognomonic symptoms include the lack of hip joint mobility and fixed abnormal position of the extremity. Any extremity motion is performed at the expense of the healthy part of the hip joint. The results of the tests allowed therapy tactics to be elucidated and corrected.
