Upper Limb Electromyographic Responses to Motor Imagery and Action Observation in Acquired Brain Injury

TL;DR

This study explores how muscle activity in the forearm changes during motor imagery and action observation in stroke patients, aiming to improve rehabilitation techniques.

Contribution

The study introduces a novel protocol using electromyography to compare muscle activation during motor imagery and action observation in acquired brain injury patients.

Findings

Electromyographic responses will be analyzed under three experimental conditions.

The protocol aims to inform future rehabilitation strategies for upper limb motor impairment.

Findings may enhance understanding of neuronal plasticity mechanisms in stroke recovery.

Abstract

Acquired Brain Injuries are one of the leading causes of mortality and disability worldwide. One of the most frequent sequelae is motor impairment of the upper limbs, which affects people’s functionality and quality of life. Following the discovery of mirror neurons, new techniques were developed based on the mechanisms of neuronal plasticity, such as motor imagery (MI) and action observation (AO). We propose a protocol using electromyographic recordings of forearm muscles in people who have suffered a stroke during an MI task and an AO task. Three different experimental conditions will be studied during the electromyographic recordings: control recording, recording during MI, and recording during AO. Understanding the muscle activation in each technique will allow us to develop future protocols and intervention plans, improving the quality of care for people who have suffered a stroke.
