Brief summary

Two movement illusion techniques can currently be used in clinical practice for motor rehabilitation after stroke hemiplegia: visual illusion (mirror therapy) and proprioceptive illusion (tendon vibration). Mirror therapy, in its computerized version (IVS3, Dessintey, Saint-Etienne, France), is based on the substitution of the deficient visual feedback by a visual feedback of a correctly realized movement. The proprioceptive illusion is based on the external application of a vibrator on muscle tendons at a frequency between 50 and 120 Hz. These two techniques are currently used independently. They are, in theory, complementary and additive. No study has described the combinatorial properties of the illusions generated by these 2 techniques in hemiplegic subjects and healthy subjects.

Detailed description

The study hypothesis is that the administration of mirror therapy together with vibration will increase the perception of movement in a subjective scale.

Interventions

Computerized Mirror Therapy (CMT) will be realizing by the device Intensive Visual Simulation 3 (IVS3). The patient looks on a screen in front of him, mirroring the movements made by his hand, while attempting to perform the same movement with his other hand.

Transcutaneous vibrations are used. This device allows vibrations from 50 to 120 Hz with amplitude of 1 mm. This study the frequency used is 70 and 80 Hz.

Design outcomes

Primary

MeasureTime frameDescription
subjective measure of the intensity of the perception of movements: change from baseline impression of movement at day 7Day: 0, 7Measured impression of movement on conditions (visual and/or proprioceptive; yes/no/don't know)
subjective measure of the intensity of the perception of movements: change from baseline nature of this impression at day 7Day: 0, 7Measured nature of this impression of movement (flexion/extension)
subjective measure of the intensity of the perception of movements: change from baseline intensity of the movement felt at day 7Day: 0, 7Measured intensity of the movement felt by Visual Analogue Scale (VAS) results (0 = no sense of movement and 10 = like real movement.)

Secondary

MeasureTime frameDescription
To compare the Visual Analogue Scale (VAS) score with the Erasmus modified Nottingham Sensory Assessment (EmNSA) scoreDay: 0Erasmus modified Nottingham Sensory Assessment (EmNSA) score evaluated the level of sensory impairment. The Erasmus modified Nottingham Sensory Assessment (EmNSA) includes 2 subscales: somatosensory score (min 0 and max 44) and stereognosis (min 0 and max 20) for left and right members.
Objective measurement of the perceived movement angle reproduced without motor intention by the hemiplegic subjects with the healthy limbDay: 0, 7Measured by Kinovea software.
Brain activity according to different experimental conditions (with and without vibration or with and without visual illusion) in hemiplegic subjects.Day: 0, 7Multi Channel EEG Acquisition System
Intensity of the perception of movements using a visual analogue scale and the objective measurement of perceived movement angle reproduced by the healthy subjects with the vibrated armDay: 0, 7Measured by Kinovea software.
Measurement of motor intention in hemiplegic subjects by experimental conditionsDay: 0, 7Measured by Visual Analogue Scale (VAS) results (0 = no sense of movement and 10 = like real movement).
To compare the Visual Analogue Scale (VAS) score according to the level of motor impairmentDay: 0Level of motor impairment is measured by Medical Research Council (MRC) score. Medical Research Council (MRC) score evaluate motricity (0= paralyzed).
