Patients with demyelinating polyneuropathy are arranged in a single treatment group and will be treated at a frequency of twice a week for five weeks. In each session, the PNF patterns will be repeated four times, on both sides, stimulating muscle irradiation and evoking the contraction of the tibialis anterior muscle. During the repetition of the patterns, the dorsiflexor muscle response of each patient will be obtained by an electromyography (EMG) surface.
