Study on the Effects of an EMG-controlled Functional Electrical Stimulator for Upper Limb for Post-stroke Patients

Официальное название

Pilot Study on the Effects Induced by an Electromyographic-controlled Functional Electrical Stimulator (FitFES) for Upper Limb Rehabilitation in Post-stroke Patients

Обзор

Upper limb disabilities are among the most debilitating issues after a cerebral stroke. One promising approach in motor rehabilitation is the use of functional electrical stimulation (FES). This technique can be integrated into daily therapy to follow an adaptive approach, exploiting the residual capacities of patients. FES can help to stimulate the affected muscles, improve coordination and strengthen the weakened muscles, thus supporting the rehabilitation process.

Подробное описание

FitFES is a wearable and non-invasive device that provides continuous stimulation set according to the residual myoelectric activity of hemiparetic muscles. Its bioinspired functioning has been implemented to restore the neurophysiological feedback from the muscles to the central nervous system while performing voluntary movements. This study aims to assess the effects of FitFES device on upper limb motor rehabilitation of post-stroke subjects, compared to traditional rehabilitation treatment. 50 post-stroke subjects will be recruited and randomized into an experimental group and a control group.

All participants will follow a 15-session rehabilitation program, and in each session they will execute task-oriented exercises. The experimental group will be assisted by the FitFES device, while the control group will perform the tasks without the device support.

Each subject will be assessed before and at the end of the rehabilitation protocol. Collected data from both groups will then be compared.
