LUNA-EMG to Enhance Motor Functions in Neurological Disorders

The aim of the present study is to evaluate the effects of training performed with the LUNA-EMG system to enhance motor functions of the upper limb in stroke This is a randomized open-label trial. Patients will be randomized into the intervention group (LUNA-EMG) or in the control group (standard care).

The effect of the training will be measured with the EMG, the upper limb motor function and the quality of life.

Treatment and study plan

LUNA-EMG

Device

The LUNA-EMG (Samcom) system is a robot that allows the evaluation of muscular strength through the recording of muscle activity (electromyography - EMG) in order to provide precise objective data on the patient's muscle function. In addition to the diagnostic aspect (evaluation of muscle strength, range of motion and proprioception), the LUNA-EMG robot allows the adaptation of movements during rehabilitation sessions according to the individually generated strength.

Primary outcomes

  1. muscular strength in mV

    Time frame: 12 weeks

    muscular strength will be measured with the EMG

Secondary outcomes

  1. Fugl-Meyer

    Time frame: 12 weeks

    The scale evaluates motor capacities of the upper limb following a stroke. Scores range from 0 to 66 (the higher the better).

  2. Modified Ashworth Scale

    Time frame: 12 weeks

    This scale measures spasticity. The results are scored from 0 to 4 (the higher the more spastic).

  3. Lovett

    Time frame: 12 weeks

    This scale measures muscular strength. The scale ranges from 0 to 5 (the higher the better).
