Introduction of short-term disturbances into the biomechanical structure of the human gait with simultaneous recording of the muscle electrical activity has been used to demonstrate that the human body has an intraspinal locomotor program consisting of an inhibition period, when afferent stimuli cause no response, and an excitation period, when the(More)
The main functions of a method of functional electrical stimulation of muscles (FES) are described: diagnostic, prognostic, and therapeutic. The main indication for using the FES method is a deficiency of muscle function, which may be organic (due to lesions to neuromuscular structures) or functional (associated with relaxation of the muscular apparatus).(More)
The electrical activities of some muscles of the lower extremities have been studied by the method of presentation of an acoustic signal for a change in walking speed. It has been established that the motor response to a signal has two stages, at which (1) the ratio of muscle activities facilitating acceleration or deceleration of walking is formed and (2)(More)
Electromyograms (EMGs) of subjects with different gait pathologies have been used to analyze the most typical forms of transformation of the muscle EMG profile: (1) a decrease in the muscle electrical activity during a locomotor cycle, either uniform or with a predominant reduction in the region of maximum values (the Mx zone); the former variant is(More)
The relative contributions of program and afferent factors to the control of human locomotion were studied using physical modeling of abnormalities of the biomechanical structure of walking and simultaneous recording of the parameters of movement and muscle electrical activity. During walking, three zones of activity were observed in electromyograms: Mx(More)
