Induced Motion Illusions Through Vision and Tendon Vibrations: Study of Interactions in Hemiplegic Subjects
- Conditions
- Hemiplegia
- Interventions
- Device: Computerized Mirror Therapy (CMT)Device: Tendon vibration
- Registration Number
- NCT04449328
- 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.

Group Intervention Description Patient with first stroke causing hemiplegic Computerized Mirror Therapy (CMT) Patient with first stroke causing hemiplegic will be included. They will have Computerized Mirror Therapy (CMT) associated at tendon vibration: * Visit 1: wrist flexion (right and left arms) with 5 randomized experimental conditions (vision+vibration, vision alone, vibration alone, static image+vibration, vision of extension+vibration(incongruence)) * Visit 2 (1 week later): wrist extension (right and left arms) with 5 randomized experimental conditions (vision+vibration, vision alone, vibration alone, static image+vibration, vision of flexion+vibration (incongruence)) These conditions will be recording by the Kinovea software, which allows the measurement of angles and amplitudes. healthy subjects Computerized Mirror Therapy (CMT) Healthy subjects will be included. They will have Computerized Mirror Therapy (CMT) associated at tendon vibration: * Visit 1: wrist flexion (right and left arms) with 5 randomized experimental conditions (vision+vibration, vision alone, vibration alone, static image+vibration, vision of extension+vibration(incongruence)) * Visit 2 (1 week later): wrist extension (right and left arms) with 5 randomized experimental conditions (vision+vibration, vision alone, vibration alone, static image+vibration, vision of flexion+vibration (incongruence)) These conditions will be recording by the Kinovea software, which allows the measurement of angles and amplitudes. healthy subjects Tendon vibration Healthy subjects will be included.

- Primary Outcome Measures
Name Time Method subjective measure of the intensity of the perception of movements: change from baseline impression of movement at day 7 Day: 0, 7 Measured 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 7 Day: 0, 7 Measured 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 7 Day: 0, 7 Measured intensity of the movement felt by Visual Analogue Scale (VAS) results (0 = no sense of movement and 10 = like real movement.)
- Secondary Outcome Measures
Name Time Method Brain activity according to different experimental conditions (with and without vibration or with and without visual illusion) in hemiplegic subjects. Day: 0, 7 Multi Channel EEG Acquisition System
Objective measurement of the perceived movement angle reproduced without motor intention by the hemiplegic subjects with the healthy limb Day: 0, 7 Measured by Kinovea software.
To compare the Visual Analogue Scale (VAS) score according to the level of motor impairment Day: 0 Level of motor impairment is measured by Medical Research Council (MRC) score. Medical Research Council (MRC) score evaluate motricity (0= paralyzed).
To compare the Visual Analogue Scale (VAS) score with the Erasmus modified Nottingham Sensory Assessment (EmNSA) score Day: 0 Erasmus 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.Measurement of motor intention in hemiplegic subjects by experimental conditions Day: 0, 7 Measured by Visual Analogue Scale (VAS) results (0 = no sense of movement and 10 = like real movement).
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 arm Day: 0, 7 Measured by Kinovea software.
