The Effect of a Rehabilitation Program for Partial Tear of the Biceps Femoris Muscle on Muscle Electrical Activity in Injured Soccer Players

Abstract

This study is important because it addresses a common injury in soccer, namely the partial tear of the biceps femoris (hamstring) muscle, due to its direct impact on player performance and continuity. The study relies on measuring muscle electrical activity using (EMG) as an accurate scientific method to evaluate recovery, instead of relying only on traditional assessments.

The research problem lies in the limited use of such measurements during rehabilitation, which may lead to players returning before full recovery and increasing the risk of re-injury. The study aims to design a rehabilitation program for this injury, identify its effect on improving muscle electrical activity, and compare pre- and post-rehabilitation results. It is that there are significant differences in favor of post-tests.

The researcher used an experimental method on a sample of (6) injured players. An 8-week rehabilitation program was applied, including physical therapy modalities, stretching, strengthening, functional exercises, and balance training. Electrical activity variables were measured before and after using (EMG).

The results showed significant improvements in all variables: amplitude increased by (53%), frequency by (93%), and duration decreased by (37%), indicating improved muscle efficiency and functional recovery.

The study concluded that the rehabilitation program was effective in improving muscle electrical activity and restoring neuromuscular balance. It recommended adopting EMG measurements in rehabilitation, focusing on balance and stretching exercises, ensuring full recovery before returning to play, and emphasizing preventive exercises and continuous follow-up.
