“…Greater focus on these two muscles in the early management of hip OA could influence outcomes positively. Many therapeutic hip exercises focus on GMed (Reiman et al, ) and there has been limited evaluation of exercises for GMin (Ganderton et al (published ahead of print, )). While high resistance exercise programs result in improved strength in a population with knee OA (Zacharias et al, ), further research is needed to identify whether a high resistance strength training program could reverse muscle atrophy and improve strength in a population with hip OA.…”

Osteoarthritis mainly affects weight-bearing joints such as the hip and knee and is the most common form of arthritis. Greater muscle atrophy with fatty infiltration of gluteal muscles and decreased hip abduction strength has previously been identified with increasing severity of radiological hip OA. However, it is well documented that radiographic findings of OA do not always correlate with clinical severity. The aim of this secondary analysis was to examine whether atrophy and strength of gluteus maximus (GMax), medius (GMed), minimus (GMin), and tensor fascia lata (TFL) is associated with the clinical severity of OA. Twenty participants with unilateral hip OA and 20 age- and sex-matched asymptomatic controls were classified on the basis of clinical severity (mild, moderate-severe and asymptomatic groups) using the Oxford hip score. Muscle volumes of GMax, GMed, GMin, and TFL were determined using magnetic resonance imaging and expressed as asymmetry between limbs. A hand-held dynamometer was used to identify hip rotation and abduction strength. Regression analyzes were used to identify the association between muscle asymmetry and patient-reported severity of hip OA. Both symptomatic groups (mild and moderate-severe) demonstrated significant asymmetry in GMax (P < 0.01) and GMin (P < 0.01). GMed asymmetry was associated with only the moderate-severe symptomatic group. Hip abduction strength was reduced in both symptomatic groups. Gluteal muscle atrophy was associated with the clinical severity of OA. Clinical severity could be a useful tool for clinicians interpreting likely gluteal muscle changes and planning rehabilitation strategies for hip OA patients. Clin.

“…A program incorporating targeted GMax and GMin muscle strengthening may therefore be of clinical value. Weight-bearing single limb exercises in neutral foot alignment can be considered for increased GMin activation (Ganderton et al, 2017a). Strengthening protocols may consider progressive resistance loading to achieve muscle hypertrophy.…”

Greater trochanteric pain syndrome (GTPS) is prevalent in women and severely impacts quality of life. A key muscle group demonstrating reduced strength are the hip abductors. An understanding of specific muscles affected will help guide targeted rehabilitation. Objectives of this case–control study were to compare gluteal and tensor fasciae latae (TFL) muscle size and quality (fatty infiltration) in women with symptomatic GTPS to asymptomatic age‐matched female controls. Magnetic resonance imaging of 16 women with GTPS (mean age 55.75 years, range 23–69) and 15 asymptomatic controls (mean age 55.60 years, range 31–66) was undertaken. Muscle volumes of the gluteus maximus, gluteus medius, gluteus minimus, and TFL were calculated. Fatty infiltration was rated using the Goutallier classification system for all muscles in their entirety, as well as anterior and posterior segments of gluteus medius and minimus. Muscle volumes and fatty infiltration were compared between groups. Significantly smaller muscle volumes were identified in the symptomatic group for the upper (P = 0.01) and lower (P = 0.04) portions of gluteus maximus, gluteus medius (P = 0.03), and gluteus minimus (P = 0.02). There was no difference in TFL (P = 0.18). Symptomatic participants displayed significantly greater fatty infiltration in gluteus maximus upper (P = 0.021) and lower (P = 0.049) when adjusted for BMI, and gluteus minimus (P = 0.018), particularly in the posterior portion (P = 0.04). Anterior gluteus minimus demonstrated high amounts of fatty infiltration in both groups. Gluteal muscle atrophy and fatty infiltration in women with GTPS suggests gluteus maximus and minimus may be an important target for rehabilitation. Clin.

“…The results of this study compare favorably with a recent study on healthy older women that investigated 3 different stance-leg, hip-hitch exercises with high to very high activity levels generated for all 3 GMed segments. 5 The single-leg bridge is a popular rehabilitation exercise that has been reported to generate high GMed activity. 1 With a substantial external torque created from the unsupported leg, moderate to high activity levels in all 3 GMed segments were required presumably to contribute to a hip extension and internal rotation torque for maintaining a neutral pelvic position throughout the exercise.…”

Context: Many different rehabilitation exercises have been recommended in the literature to target the gluteus medius (GMed) muscle based mainly on single-electrode, surface electromyography (EMG) measures. With the GMed consisting of 3 structurally and functionally independent segments, there is uncertainty on whether these exercises will target the individual segments effectively. Objective: To measure individual GMed segmental activity during 6 common, lower-limb rehabilitation exercises in healthy young adults, and determine if there are significant differences between the exercises for each segment. Method: With fine-wire EMG electrodes inserted into the anterior, middle, and posterior segments of the GMed muscle, 10 healthy young adults performed 6 common, lower-limb rehabilitation exercises. Main Outcome Measures: Recorded EMG activity was normalized, then reported and compared with median activity for each of the GMed segments across the 6 exercises. Results: For the anterior GMed segment, high activity was recorded for the single-leg squat (48% maximum voluntary isometric contraction [MVIC]), the single-leg bridge (44% MVIC), and the resisted hip abduction–extension exercise (41% MVIC). No exercises recorded high activity for the middle GMed segment, but for the posterior GMed segment very high activity was recorded by the resisted hip abduction–extension exercise (69% MVIC), and high activity was generated by the single-leg squat (48% MVIC) and side-lie hip abduction (43% MVIC). For each of the GMed segments, there were significant differences (P < .05) in the median EMG activity levels between some of the exercises and the side-lie clam with large effect sizes favoring these exercises over the side-lie clam. Conclusions: Open-chain hip abduction and single-limb support exercises appear to be effective options for recruiting the individual GMed segments with selection dependent on individual requirements. However, the side-lie clam does not appear to be effective at recruiting the GMed segments, particularly the anterior and middle segments.
