“…Gottschalk et al [17] proposed in their muscle modeling studies that the main function of the TFL is hip abduction. Sidorkewicz et al [43] found that the activity of the TFL does not vary significantly during hip abduction exercise with neutral hip and internal and external rotations, which was in agreement with our findings.…”

Study Design: Controlled laboratory cross-sectional study. Background: Hip abductor muscle weakness is associated with various lower extremity injuries. Side-lying hip abduction exercises to strengthen the hip abductor muscles is frequently used in rehabilitation and injury prevention programs without scientific evidence regarding their ability to activate the targeted muscles. In addition, previous studies have not quantified the activity of hip abductor muscles during side-lying hip abduction exercises in different directions. Objectives: To measure the T2 values of hip abductor muscles during side-lying hip abduction exercises in different directions using magnetic resonance imaging and to clarify variations in the activity of each segment of the gluteus medius, upper fiber of the gluteus maximus, gluteus minimus, and tensor fasciae latae. Methods: The T2 values measured using magnetic resonance imaging were used to quantify the activity level of the hip abductor muscles in 10 healthy young males during side-lying hip abduction with different directions (neutral hip, internal rotation and flexion, external rotation, and extension). The two-way repeated measures analysis of variance analysis was used to determine differences between the groups over time. Results: The T2 values of all muscles, excluding the upper fiber of the gluteus maximus, significantly increased after exercise with all motor tasks over time. The anterior segment of the gluteus medius was significantly increased with side-lying abduction with internal rotation and flexion compared to that with side-lying abduction with external rotation and extension. In contrast, the posterior segments of the gluteus medius and upper fiber of the gluteus maximus were significantly increased with side-lying abduction with external rotation and extension compared to that during other tasks. Conclusions: The results suggest that side-lying hip abduction exercise with different directions influences the difference in muscle activity between hip abductor muscles and reflects differences in the function of the hip abductor muscles.

“…The BKFO and CLAM are used as hip joint exercises in a non-load environment. Electromyography activities of the gluteus medius during performance of the CLAM are lower than those during crotch ABD exercises conducted in the hip and knee extension positions 9 , 10 ) . Moreover, the authors reported that the activity of the gluteus medius during the CLAM is lower than that during hip ABD exercises conducted in the hip and knee extension positions.…”

[Purpose] This study aimed to investigate the relatedness, reliability, and validity of isometric muscle strength measurements of hip abduction and abduction with an external hip rotation in a bent-hip position using a handheld dynamometer with a belt. [Subjects and Methods] Twenty healthy young adults, with a mean age of 21.5 ± 0.6 years were included. Isometric hip muscle strength in the subjects’ right legs was measured under two posture positions using two devices: a handheld dynamometer with a belt and an isokinetic dynamometer. Reliability was evaluated using an intra-class correlation coefficient (ICC); relatedness and validity were evaluated using Pearson’s product moment correlation coefficient. Differences in measurements of devices were assessed by two-way ANOVA. [Results] ICC (1, 1) was ≥0.9; significant positive correlations in measurements were found between the two devices under both conditions. No main effect was found between the measurement values. [Conclusion] Our findings revealed that there was relatedness, reliability, and validity of this method for isometric muscle strength measurements using a handheld dynamometer with a belt.

“…In total, 438 asymptomatic subjects were evaluated within these studies with a varied underlying activity history. Apart from 2 studies that included males only, 22,23 1 study that included females, 13 and 1 study which did not report gender distribution, 11 the remaining 16 studies evaluated exercises in a spread of males and females. The range of subject ages was generally not reported within studies, though the group means of each study ranged from 21.0-31.2 years.…”

Context: Gluteus medius rehabilitation is of critical importance given its role in pelvic and lower limb stability, and the known link between gluteus medius weakness and many lower limb conditions. Objective: To systematically review the literature and present an evidence-based graduated series of exercises to progressively load gluteus medius. Evidence Acquisition: A systematic literature search was conducted in January 2016 to identify studies reporting gluteus medius muscle activity as a percentage of maximal volitional isometric contraction (MVIC), during rehabilitation exercises. Studies that investigated injury free participants were included. No restrictions were placed on the type or mode of exercise, though exercises that could not be accurately replicated or performed within an independent setting were excluded. Studies that did not normalize electromyographic activity to a side lying MVIC were excluded. Exercises were stratified based on exercise type and %MVIC: low (0% to 20%), moderate (21% to 40%), high (41% to 60%), and very high (> 61%). Evidence Synthesis: 20 studies were included in this review, reporting outcomes in 33 exercises (and a range of variations of the same exercise). Prone, quadruped, and bilateral bridge exercises generally produced low or moderate load. Specific hip abduction/rotation exercises were reported as moderate, high, or very high load. Unilateral stance exercises in the presence of contralateral limb movement were often high or very high load activities, while high variability existed across a range of functional weight-bearing exercises. Conclusions: This review outlined a series of exercises commonly employed in a rehabilitation setting, stratified based on exercise type and the magnitude of gluteus medius muscular activation. This will assist clinicians in tailoring gluteus medius loading regimens to patients, from the early postoperative through to later stages of rehabilitation.
