Electromyography-biofeedback on the Motor Activation of the Extension of the Hand

Overview

Background: Biofeedback-Surface electromyography (BIO-SEMG) is a relatively recent physiotherapy technique. Although its use is widespread in sports science and sports performance, its use for the rehabilitation of patients with neurological pathologies is less studied.

Objective: The purpose of this research was to determine the changes that occur in the application of BIO-SEMG in the muscles responsible for the extension and the dorsiflexion of the hand and the foot in subjects with cerebrovascular damage.

Design: A randomized, double-blind, two-arm parallel group study was performed.

Patients: A sample of 28 subjects with limited extension of the hand and dorsiflexion of the foot as a consequence of a stroke was randomized divided in intervention or control groups.

Methods: The subjects of the intervention group underwent 12 sessions of BIO-SEMG, of 15-minute duration each of them, in the upper and lower members. On the other hand, the control group underwent another 12 sessions of 15-minute duration, in which manual physiotherapy techniques were performed.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Supportive Care
    • Masking: Double (Participant, Investigator)
  • Study Primary Completion Date: November 30, 2017

Interventions

  • Device: surface electromyography-biofeedback
    • Two electrodes were putted on the motor point of the extensor muscle of the hand and the foot. The positive electrode was placed on the distal zone of the hand or the foot, while the negative electrode was placed on the proximal zone.

Arms, Groups and Cohorts

  • Experimental: INTERVENTION
    • A group that underwent a neurological physiotherapy program with electromyography-biofeedback on the hand and the foot
  • Active Comparator: CONTROL
    • A group that underwent a conventional physiotheraphy intervention

Clinical Trial Outcome Measures

Primary Measures

  • Extension Degree
    • Time Frame: 3 months
    • Change in the extension ability of the upper an lower members depending on the activity of the extensor muscles

Secondary Measures

  • Fugl Meyer Test
    • Time Frame: 6 months
    • Severity degree of the stroke-derived consequences
