“…These procedures allowed comparisons between different individuals and studies and reduced the inter-subject coefficients of variation 24 . Normalization by the maximum voluntary contractions was not chosen, as previously employed 25 , because this procedure could not have been trustworthy for individuals with LBP, as they would not be able to perform maximum contractions due to the pain [26][27][28][29] .…”

“…Seven complained of pain in the direction of extension, three in the direction of flexion, seven in both directions, and two did not show any specific patterns. Clinically, these individuals had a score of 28.58 [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] Figure 2 shows the muscular latencies of all investigated muscles for the asymptomatic (2a) and LBP (2b) individuals. For the asymptomatic group, the muscular activation patterns were initiated by the semitendinosus, followed by the ipsilateral erector spinae, contralateral erector spinae and finished by the gluteus maximus.…”

“…A systematic review that investigated exercise therapy for improving muscle activity onset times concluded that training involving selective muscle activation improves muscle activity onset times 8 ) , suggesting that training involving selective GM activation might improve GM activity patterns in people with low back pain. One exercise for suppressing HAM activity and activating GM that is often used clinically is prone hip extension with knee flexion (PHEKF) 9 ) . Kang et al 10 ) and Sakamoto et al 9 ) investigated the impact of muscle activity during PHEKF exercise using hip joint abduction and external rotation to discover a method for activating the GM.…”

[Purpose] This study investigated the selective activation of the gluteus maximus during a prone hip extension with knee flexion exercise, with the hip joint in different positions. [Subjects] The subjects were 21 healthy, male volunteers. [Methods] Activities of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using surface electromyography during a prone hip extension with knee flexion exercise. Measurements were made with the hip joint in each of 3 positions: (1) a neutral hip joint position, (2) an abduction hip joint position, and (3) an abduction with external rotation hip joint position. [Results] Gluteus maximus activity was significantly higher when the hip was in the abduction with external rotation hip joint position than when it was in the neutral hip joint and abduction hip joint positions. Gluteus maximus activity was also significantly higher in the abduction hip joint position than in the neutral hip joint position. Hamstring activity was significantly lower when the hip was in the abduction with external rotation hip joint position than when it was in the neutral hip joint and abduction hip joint positions. [Conclusion] Abduction and external rotation of the hip during prone hip extension with knee flexion exercise selectively activates the gluteus maximus.

“…For pelvic stability and safe and effective movement of the lower limbs, a GM strengthening exercise has been applied for rehabilitation training. The GM strengthening exercise, prone hip extension with knee flexion (PHEKF) exercise, is a well-known, effective method for activation of the GM muscle during lower limb extension [11]. Recent research on application of the PHEKF exercise has used electromyography (EMG) and measurement of the angle of the leg to assess the activation of the GM [12].…”

The aim of this study was to investigate the inter-rater and intra-rater reliability of rehabilitative ultrasound imaging (RUSI) for measurement of muscle thickness with changes in angles of the gluteus maximus (GM) at rest and during contraction. Design: Cross-sectional study. Methods: Twenty-two healthy men volunteered for this study. GM muscle images were obtained in the resting position and during prone hip extension with knee flexion at hip abduction angles of 0° and 30°, respectively. Two examiners randomly measured the thickness of the GM twice in three different positions. The first position was a comfortable prone position. The second position was prone hip extension with knee flexion (PHEKF) to 90°. The third position was achieved by hanging a 1-kg weight on the ankle of the lifted leg during PHEKF with the angle of the lifted leg the same as the second position. Intra-class correlation coefficients (ICCs), standard error measurements, and minimal detectable changes were used to estimate reliability. Results: The intra-rater reliability ICCs (95% confidence interval) of the GM were >0.870, indicating good reliability. Inter-rater reliability ICCs ranged from 0.668 to 0.913. The reliability of measurements of muscle thickness at each position was similar to the reliability of the angle change. Differences in muscle thickness and ratios for each position with 0° and 30° of hip abduction were not statistically significant. Conclusions: In the present study, the intra-rater reliability of muscle thickness measurements of the GM was good, and the inter-rater reliability was moderate to good. Reliable RUSI measurements of wide and large muscles, such as the GM muscle at rest and during contraction, are feasible. Further investigation is required to establish the reproducibility of the protocols presented in this study.
