We developed a motor-driven joint exerciser for the hip and knee incorporating three-dimensional load sensors in the thigh and calf supports of the machine. The machine can memorize and replay exactly the same exercise as therapists teach with three degrees of freedom of motion in the median plane. The present investigation focuses on the virtual mechanical impedance control which enables soft and elastic movement like the ROM by the human therapists. To demonstrate effects of the exerted impedance the torque of the joints was measured in the normal and spastic subjects during passive ROM exercises. The results indicate less torque; therefore, smoother motion, in the presence of such impedance. It was also suggested the ROM exercise free of mechanical stress on the joints was accomplished by the machine with multi-degrees of freedom of motion.
LOCAL DECOMPRESSION IN COMPLEX TREATMENT OF WOMEN WITH THE BENIGN EPITHELIAL OVARIAN TUMORS

Today generally acknowledged method of the benign epithelial ovarian tumors (BEOT) treatment is surgical. However, in far-off period after the radical or conservative operation in operated or intact ovary the relapses of tumor are found along with the tumors in hormonaldependent organs (uterus, breast) due to the preservation of the tumor's growth background in patients after the operation, that proves the necessity of the II stage treatment. With this aim in different clinical groups of women with BEOT after the operation we used local decompression (LD) and its combination with hormonal therapy (HT).
Using clinical, instrumental, biochemical, radioimmune methods and enzyme multiplied immunoassays we examined 502 women of fertile age with BEOT as well as 37 healthy non-pregnant women as a control group to determine serum levels of hypophyseal and sex hormones, proteases (P) and their inhibitors (PI) along with differential rheography of pelvic organs. LD and HT was performed according to the worked out methodics.
The activation of proteolysis system, the normalization of hormonal homeostasis figures and the improvement of the ovarian haemodynamics occur through the influence of local decompression. Treatment effectiveness obviously is connected with the ischemia liquidation in pelvic organs. The use of local decompression on the II stage of BEOT treatment is pathogenetically approved and effective.
