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.

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.

Study Groups

Active tDCS

During the first 20 min of training program, patient will have active tCDS (2 mA )

Group Type: EXPERIMENTAL

Active tDCS

Intervention Type: DEVICE

During the first 20 min of training program, patient will have active tCDS : 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.

sham tDCS

During the first 20 min of training program, patient will have sham tCDS

Group Type: SHAM_COMPARATOR

Sham tDCS

Intervention Type: DEVICE

During the first 20 min of training program, patient will have sham tCDS : the patient received a 2 mA anodal tDCS (only during the first and the last 30 seconds of the stimulation) and then, patient will have sham tDCS. The anodal electrode was positioned on the hotspot previously identified with TMS. The cathode was placed above the contralesional orbit.

Interventions

Active tDCS

During the first 20 min of training program, patient will have active tCDS : 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.

Intervention Type: DEVICE

Sham tDCS

During the first 20 min of training program, patient will have sham tCDS : the patient received a 2 mA anodal tDCS (only during the first and the last 30 seconds of the stimulation) and then, patient will have sham tDCS. The anodal electrode was positioned on the hotspot previously identified with TMS. The cathode was placed above the contralesional orbit.
