The Influence of EMG-triggered Robotic Movement on Function and Mobility of Stroke Patients

Rehabilitation of lower limbs after a stroke supported by robots aims to return to independence and minimize disability caused by the incident, but the results have been mixed. Objective of the study was to assess the changes in gait capabilities, muscle tone and daily activities in patients after a recent stroke who underwent a 6-week supervised rehabilitation process using exercises on the LUNA EMG neurorehabilitation robot. A total of 60 participants with impaired motor function and gait after subacute stroke were included in the study. Each patient was randomly assigned to an intervention (robot) or control group (RG or CG). All patients, except standard therapy, underwent 1 session of therapy per day, 5 days a week for 6 weeks. People with RG had 30 minutes of training sessions on the Luna EMG robot, while CG received exercises on the lower limb rotor. Patients were evaluated before the start of the study, and then after 2, 4 and 6 weeks of therapy using the Ashworth scale, Rivermead mobility index (RMI), Repty functional index, Time Up and Go test (TUG) and muscle circumference on the thigh.
