“…19 Furthermore, simply considering the role of the GM as a homogeneous muscle does not reflect findings on anatomical dissection. 22,25,26 These anatomical studies suggest that the GM consists of distinct functional subdivisions (anterior, middle, and posterior), similar to other muscle groups-for example, the trapezius and gluteus maximus. 27,28 Consequently, many rehabilitation programs for the GM are based on the presence of these functional subdivisions.…”

“…We hypothesized that there would be a significant difference in the activation pattern of the GM subdivisions, with the anterior and middle subdivisions contributing more to abduction and internal rotation of the thigh because of their almost vertical anatomical alignment. 22,25,26 Conversely, we hypothesized that the posterior aspect of the GM would contribute more to external rotation of the thigh because of its more horizontal alignment. 22,25 …”

Context: Functional subdivisions are proposed to exist in the gluteus medius (GM) muscle. Dysfunction of the GM, in particular its functional subdivisions, is commonly implicated in lower limb pathologies. However, there is a lack of empirical evidence examining the role of the subdivisions of the GM. Objectives: To compare the activation of the functional subdivisions of the GM (anterior, middle, and posterior) during isometric hip contractions. Design: Single-session, repeated-measures observational study. Setting: University research laboratory. Participants: Convenience sample of 15 healthy, pain-free subjects. Intervention: Subjects performed 3 maximal voluntary isometric contractions for hip abduction and internal and external rotation on an isokinetic dynamometer with simultaneous recording of surface electromyography (sEMG) activity of the GM subdivisions. Main Outcome Measures: sEMG muscle activity for each functional subdivision of the GM during each hip movement was analyzed using a 1-way repeated-measures ANOVA (post hoc Bonferroni). Results: The response of GM subdivisions during the 3 different isometric contractions was significantly different (interaction effect; P = .003). The anterior GM displayed significantly higher activation across all 3 isometric contractions than the middle and posterior subdivisions (main effect; both P < .001). The middle GM also demonstrated significantly higher activation than the posterior GM across all 3 isometric contractions (main effect; P = .027). There was also significantly higher activation of all 3 subdivisions during both abduction and internal rotation than during external rotation (main effect; both P < .001). Conclusions: The existence of functional subdivisions in the GM appears to be supported by the findings. Muscle activation was not homogeneous throughout the entire muscle. The highest GM activation was found in the anterior GM subdivision and during abduction and internal rotation. Future studies should examine the role of GM functional subdivisions in subjects with lower limb pathologies.

“…Gluteus maximus and minimus are important in the role of frontal stability of the pelvis and should work synergistically rather than in isolation in assessment and rehabilitation of frontal plane stability of the injured athlete [68]. Jae-seop et al [69] demonstrated that the amplitude of gluteus maximus contraction increased by performing an abdominal drawing in manoeuvre.…”

Hip and Groin Pain: Physiotherapy and Rehabilitation Issues

Groin and hip injuries are common in sport. The diagnosis, treatment and rehabilitation of these injuries has long been identified as a complex and challenging area for all clinicians involved in the management of such injuries. While our knowledge increases steadily the challenge still remains for appropriate and successful treatment strategies. Rehabilitation has been identified as an important factor in the management of hip and groin pain. Rehabilitation can occur prior to and after surgery or can be a stand alone treatment for long standing or acute pain. Due to the number and complexity of injuries in the hip and groin area, the physiotherapist must have a strong anatomic and biomechanical knowledge base in order to identify possible aggravating structures or movement abnormalities during the assessment process. Often there is not one single cause for the symptoms but multiple causes. If rehabilitation is appropriate the physiotherapist must put in place a progressively graded rehabilitation programme appropriate to a given sport. There are still gaps in the literature on the provision of the specifics of successful rehabilitation. Therefore the physiotherapist must use sound principles of healing, exercise physiology, manual therapy and rehabilitation, in addition to knowledge of specific stresses and strains that the pelvic area is exposed to within a given sport, in order to provide a successful outcome for the athlete.

“…It is composed of three distinct sections: the anterior, middle and posterior GM fibers 4,5) . The actions of these segments differ: the anterior GM fiber is involved in hip abduction and internal rotation and assists flexion; the middle GM fiber is involved only in abduction of the hip; and the posterior fiber is involved in hip abduction and external rotation, and assists extension 6,7) .…”

Abstract.[Purpose] The purpose of this study was to investigate the activation of subdivisions of the gluteus medius during modified unilateral weight-bearing exercises using a pressure-biofeedback unit in order to suggest the most effective exercise method.[Subjects] We recruited 15 healthy adult females with no pain in the gluteus medius and no other orthopedic problems in the lower limbs.[Methods] The enrolled individuals performed four modified unilateral biofeedback exercises: wall-press with adduction force, WP-ADD; wall-press with abduction force, WP-ABD; wall-squat with adduction force, WS-ADD; and wall-squat with abduction force.[Results] The anterior and middle fibers of the gluteus medius were highly activated during WP-ADD, and the posterior fiber of the gluteus medius was activated during WS-ABD.[Conclusion] These results suggest that weight-bearing exercises for gluteus medius strengthening should be more specific, and chosen based on the characteristics of each subdivision.
