Effects of Local Vibrations Program of Dorsiflexor Muscles on Neuromotor Recovery in Subacute Stroke Patients - a Multicentric Randomized Controlled Study

Обзор

The aim of the vibration intervention proposed in the current study is to allow a better neuromotor recovery in subacute stroke patients when compared with standard rehabilitation alone. These last years, it has been proven that the solicitation of a muscle using vibrations may lead to positive effects on the neuromuscular function. Thus, the aim of the current study is to assess if the addition to a standard rehabilitation program of local vibrations sessions of the dorsiflexor muscles of the paretic limb of stroke patients may allow a better recovery of walking speed (primary outcome). One group using vibrations (i.e. experimental group) and one group with sham vibration (i.e. control group) will take part to this study.

Вмешательства

• Устройство Vibration
  The program will take place over 40 sessions : 5 sessions per week, for 2 months (40 sessions in total over 8 weeks during the hospitalization in the department); this group will benefit from an effective vibration of a frequency of 100Hz
• Устройство Sham vibration
  The program will take place over 40 sessions: 5 sessions per week, for 2 months (40 sessions in total over 8 weeks during hospitalization in the department); this group will not benefit from effective vibration.
• Другое 10 meters Walk Test
  Short-distance ambulation speed is measurement between 2 markers on the ground 10 meters apart in a corridor with flat ground, the patient starting his walk 3 meters before to have a launched march disregarding markers, and ends 3 meters After. The stopwatch is started when the markers are crossed.
• Другое 2 Minute Walk Test (2MWT)
  Long-distance ambulation speed is measured from a standing start and the test involves asking the patient to walk as far as possible in 2 minutes.
• Другое Fugl-Meyer (FMA-LE)
  The Fugl-Meyer (FMA-LE) assessment of motor skills : measurement of the intensity of reflexes, as well as an assessment of voluntary movements and motor coordination. Score from 0 to 34
• Другое Modified Ashworth scale
  The modified Ashworth scale allows the measurement of spasticity, that is to say the measurement of muscle tone by mobilizing the segment of the lower limb and by evaluating the resistance to stretching of the muscles. Score from 0 to 4
• Другое ABILOCO questionnaire
  The ABILOCO questionnaire evaluate the autonomy in the walking capacities of the patients (13-items)
• Другое Barthel index
  The Barthel index measure autonomy in daily life.
• Другое isometric ergometer
  Evaluate voluntary maximum force in isometric ankle dorsiflexion by Cybex isometric ergometer results.
• Другое Electromyograms (EMG)
  Assessment of neuromuscular fatigue by electromyograms (EMG). Surface electrodes is place on the tibial muscle anterior to non-invasively collect electromyograms (EMG). The intensity of stimulation will be gradually increased until a plateau in mechanical (strength) and electromyograms (EMG) responses is obtained.
