# Neuromuscular Rehabilitation of the Brachioradialis Muscle after Distal Radius Fracture in Two Professional Soccer Players Using Electromyographic Biofeedback

## TL;DR

Two professional soccer players recovering from wrist fractures used EMG biofeedback to improve muscle control, showing promising results.

## Contribution

This study demonstrates the efficacy of EMG-BF in neuromuscular rehabilitation of brachioradialis muscle after sports injuries.

## Key findings

- EMG-BF intervention led to a statistically significant increase in brachioradialis muscle activity.
- The ABA design showed improved voluntary control of electromyographic activity after six sessions.
- Follow-up session confirmed sustained improvement in muscle activity.

## Abstract

The use of electromyographic biofeedback (EMG-BF) in the rehabilitation of injuries has been widely referenced in the psychological literature. However, despite some pioneering work in the field of sports, its use in the rehabilitation of sports injuries has hardly been explored. A case of two professional soccer players who each suffered a distal radius fracture is presented here. Parallel to the rehabilitation plan established by medical services, an intervention strategy using EMG-BF was established. An EMG-BF intervention was performed on the brachioradialis muscle with the aim of improving the voluntary control of its electromyographic activity. The study protocol was registered with the identifier NCT05376072. An ABA design was used. In each session, a pre- and postline was recorded to determine the EMG gain acquired at each point of the session. After six sessions, the intervention was terminated. One more follow-up session was performed. The results obtained indicated the efficacy of the intervention; a statistically significant increase in muscle activity in the brachioradialis muscle was observed.
