Low Back Pain (LBP) is one of the most common skeletal disorders, with an incidence possibility of up to 80% during one's life. Before planning a rehabilitation program, an accurate evaluation seems to be necessary in people with LBP. With regard to the kinetic chain of human body, any problem or dysfunction in any part of the chain can cause abnormal function in other parts. Abnormal hip kinematics and impaired hip muscle performance have been associated with LBP. So, the purpose of the current study was to compare electric activity ratio of gluteal muscles to tensor fascia lata in males with and without non-specific chronic LBP.
A total of 15 healthy males and 15 males with non-specific chronic LBP participated in the present semi-experimental study. Electromyography signals were obtained from the gluteus medius, superior gluteus maximus, and TFL muscles at 1000 Hz frequency as participants performed some selected exercises and the gluteal-to-TFL muscle activation indices were calculated. Repeated measures analysis of variance and independent t-test were run for data analysis.
The results of the present study demonstrated that, compared with the low back pain group, in launch, squat, hip abduction, clam in side lying, lateral step down, hip extension with extend knee, hip extension with flexed knee, one-side bridge, two-side bridge, and cutting maneuver with elastic resistance, gluteal muscles were significantly more active in healthy group (P The result of the present study shows that the electromyography activity index differs between the gluteal muscles and the tensor fascia lata in people with non-specific chronic LBP and healthy people. In order to plan rehabilitation exercise, the clam in side lying, cutting maneuver with resistance elastic, unilateral, and bilateral bridge exercises can be suggested to people with LBP, with the exception of lunch and squat exercises.
