The Effect of NeuroMuscular Electrical Stimulation on Quadriceps Strength and Knee Function in Professional Soccer Players: Return to Sport after ACL Reconstruction

Abstract EN

The aim of this study was to assess the clinical efficacy and safety of NMES program applied in male soccer players (after ACL reconstruction) on the quadriceps muscle.

The 80 participants (NMES = 40, control = 40) received an exercise program, including three sessions weekly.

The individuals in NMES group additionally received neuromuscular electrical stimulation procedures on both right and left quadriceps (biphasic symmetric rectangular pulses, frequency of impulses: 2500 Hz, and train of pulses frequency: 50 Hz) three times daily (3 hours of break between treatments), 3 days a week, for one month.

The tensometry, muscle circumference, and goniometry pendulum test (follow-up after 1 and 3 months) were applied.

The results of this study show that NMES (in presented parameters in experiment) is useful for strengthening the quadriceps muscle in soccer athletes.

There is an evidence of the benefit of the NMES in restoring quadriceps muscle mass and strength of soccer players.

In our study the neuromuscular electrical stimulation appeared to be safe for biomechanics of knee joint.

The pathological changes in knee function were not observed.
