FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to a method of controlling an amortization change in an artificial knee joint of an orthosis, an exoskeleton or a prosthesis. Artificial knee joint has an upper part and a lower part, which are fixed on each other with the possibility of rotation around the axis of rotation. Between the upper part and the lower part a resistance unit is fixed to provide resistance against flexion or extension of the artificial knee joint. With the resistance unit, a control device is matched, by means of which the resistance is changed, if the signal of the sensor of the control unit coordinated with the control device activates the adjustment device. For bending phase, bending resistance decreases. During walking or standing, change of at least one load parameter is registered, which influences orthosis or prosthesis. Maximum value of change of load parameter during stop or standing phase is set. After reaching the maximum when the threshold value of the load parameter is lower than the maximum, the bending damping is reduced during the stop phase to the level of damping of the fly phase.
EFFECT: invention provides, at increased protection against unintentional flexion, the possibility of flexible adaptation of launching of the fly phase at various situations during walking or various walking speeds, as well as under load of bending.
