Study Description

Brief Summary

Transcortical direct current stimulation (tDCS) is an emerging technique in the rehabilitation of hemiplegic patients after stroke.

This study aims to assess the observance and the tolerance of repeated tDCS stimulation over the primary motor cortex of the lower limb coupled to a motor training program, among hemiplegic patients at the sub-acute stage. This is a prospective, randomized, double-blind, study with two parallel groups of 15 subjects each. The study will analyze first, the patient's observance considered good if 75% of the patients completed the entire protocol duration and the tolerance through a questionnaire. The secondary end point will try to estimate, if possible, the effect size of the walking performance measured with the six-minute walk test and aerobic performance measured with VO2peak of this training program compared to the same program combine with placebo stimulations. These evaluations are performed before, during and after the rehabilitation program.

Condition or Disease	Intervention/Treatment	Phase
Hemiplegia Stroke	Device: Active tDCS Device: Sham tDCS	N/A

Detailed Description

During the initial 20 min of each session, the patient received a 2 mA anodal tDCS over the lower limb ipsilesional motor area. The anodal electrode was positioned on the hotspot previously identified with TMS. The cathode was placed above the contralesional orbit. The pseudo stimulation reproduces during the first and the last 30 seconds of the stimulation, tingling feelings due to current flow experienced during tDCS. In this way there is no possibility for the patient to recognize the difference between the real and the placebo stimulation.
