The article presents the results of a study of the reflex mechanisms of reciprocal and presynaptic inhibition at rest and when performing an isometric reduction of 5% of MPS against the background of twenty-minute non-invasive electrical stimulation of the spinal cord. It was found that at rest against the background of electrical stimulation, reciprocal and presynaptic inhibition was inverted to their relief, and when performing plantar flexion of the foot, on the contrary, reciprocal and presynaptic inhibition increased, but the severity of presynaptic inhibition was greater.
 Key words: percutaneous electrical stimulation of the spinal cord, reciprocal inhibition, presynaptic inhibition, isometric contraction.
