Abstract

Background &Purpose: Patellofemoral pain syndrome (PFPS) is one of the most common disorders of the knee in active individuals and athletes. Poor neuromuscular control of the glutus medius muscle is important in patellofemoral pain syndrome. The aim of this study was to investigate the EMG activity of gluteus medius muscle in response to dynamic postural perturbation in athletes with and without PFPS.
Methodology: 12 male athletes with PFPS (age 23/75 ± 3/27 years, height 1/79 ± 7/71 m, weight 74/87 ± 8/62 kg) and 12 healthy male athletes (age 22/91 ± 2/67 years, height 1/77 ± 5/03 m, weight 69/52 ± 6/34 kg) participated in the study. EMG activity of gluteus medius measured using a 16-channel BTS-FREEEMG 300; EMG System during dynamic postural perturbation. To data Analysis Descriptive statistics and Independent t-test were used to compare two groups. The α level was set at 0.05.
Results: The results showed that no significant difference between two groups of PFPS and controls in Peak-RMS and Average-RMS (PConclusion: Regarding participating athletes in numerous training programs, it is likely that the physiological characteristics, neuromuscular factors and motor unit recruitment pattern of muscles be different in athletes and non-athletes.
