Peripheral electrical stimulation on neuroplasticity and motor function in stroke patients: a systematic review and meta-analysis.

INTRODUCTION

The use of electrotherapy has been presented as a great resource for the professional physiotherapist in the most diverse pathologies. Stroke is a neurological condition responsible for sequelae such as hemiplegia that directly impair the quality of life of patients.

OBJECTIVE

This study aimed to review the literature on the effects of electrotherapeutic resources on motor function and neuroplasticity in individuals with post-stroke sequelae.

MATERIALS AND

METHODS

2427 articles were found in databases according to search criteria for each base according to the included descriptors (EndNote Web). After exclusion of duplicate articles, automatically and manually, Phase 1 was performed - reading of titles and abstracts of 1626 articles according to eligibility criteria by two blinded reviewers using the programme Rayyan QCRI (Qatar Computing Research Institute), conflicts were resolved in consensus between the two reviewers. Thus, 13 articles were selected for Phase 2-13 articles were selected for reading in full, leaving 8 articles in this review. To assess the quality of bias of the selected studies, the PEDro Scale was used.

RESULTS

In the assessment of neuroplasticity, statistically significant results were found in two studies (p < 0.05). However, the effects of electrostimulation stood out significantly in the motor function of these individuals (p < 0.05). It can be considered with neuroplasticity, since improved functionality can be related to electrostimulation-induced neuroplasticity. Conclusions Electrostimulation is able to promote neuroplasticity and increase motor function, generating positive effects in the treatment of individuals with post-stroke sequelae.
