![]() ![]() compared a variety of proposed exercises to find the GMd activation and gluteus minimus muscles using surface electromyography ( 24). Nevertheless, researchers have reported controversial results with respect to the level of GMd activation ( 22, 23). Hip abduction has gained several regards among the exercises with different ranges of motion (ROM) from 25 to 45 degrees ( 16- 18) because it is easy to do and appropriately involves the GMd muscle ( 19- 21). lunge, single-limb squat, pelvic drop, and hip abduction, have been proposed to strengthen the GM ( 12- 15). Prescription of physical therapeutic exercise is an influencing route to recover the ability of contraction of a certain muscle ( 12). Several disorders such as low back pain ( 8, 9), fracture of the tibia ( 10), and injury to the anterior cruciate ligament ( 5, 11) are related to malfunction of the GM. It was reported that the GM frailty might influence other muscles, joints, and soft tissues in the vicinity of the pelvic region in addition to constraining hip joint kinesiological maneuvers ( 7). Furthermore, the stability and right positioning of the femur rely on the appropriate activation of the GM ( 5, 6). The most important activities of the gluteal muscles (GM), mainly gluteus maximus and gluteus medius (GMd), are to extend and abduct the hip joint during human gait ( 1, 2), and also to provide stability for the pelvis the standing position and during some phases of the gait ( 3, 4). Muscular weakness may adversely affect several functionalities that are expected to perform by gluteal muscles. The side-lying exercise may extremely involve the muscle, specifically in weaker individuals.Įxercise Hip Abduction Muscle Activation Strength Biomechanics 1. The rehabilitation of the weak hip abductor muscles may start with standing no-weight cases and continue by adding extra weights.
