“…Muscle volume may be associated with disease severity or symptom duration, with muscle atrophy occurring with more advanced OA or longer duration of symptoms. 38 We do not know if OA existed in the women in our study, however, given their relatively young age the presence of OA is unlikely. Given the preliminary nature and small samples sizes of the previous studies and our current study, caution should be taken when interpreting these findings.…”

“…It is possible the older participants in previous studies may have some age-related muscle atrophy resulting in smaller muscle volume, however, muscle atrophy was reported in only those older individuals with advanced hip OA. 38 Older individuals with mild disease demonstrated no difference 38 or greater muscle volume 14 compared to controls. Visual assessment of our data suggests no relationship between age and gluteal muscle volume in our sample, however our sample is limited to those between 18 and 40 years old.…”

“…With close assessment of the individual studies cited in their review and another recently published study, there is some evidence to suggest that findings may be affected by the participant’s age, stage of disease, or symptom duration. 14, 25, 38 When comparing symptomatic limbs in those with hip OA to asymptomatic participants, Zacharias et al 38 found that individuals with advanced OA (K/L 3), had significantly smaller GMax, GMed, and GMin. However, those with mild hip OA (K/L 2), had similar muscle volume to that of asymptomatic people.…”

Study Design Secondary analysis, cross-sectional study Background Chronic hip joint pain (CHJP) can lead to limitations in activity participation, but the musculoskeletal factors associated with the condition are relatively unknown. Understanding the factors associated with CHJP may help develop rehabilitation strategies to improve quality of life of individuals with long-term hip pain. Objectives To compare measures of hip abductor muscle volume and hip abductor muscle strength between women with CHJP and asymptomatic controls. Methods Thirty women, 15 with CHJP and 15 matched asymptomatic controls (18–40 years of age), participated in this study. Magnetic resonance imaging was used to determine the volume of the primary hip abductor muscles, consisting of gluteus medius (GMed), gluteus minimus (GMin), a small portion of gluteus maximus (GMax), and tensor fascia latae (TFL), within a defined region of interest. Break tests were performed using a handheld dynamometer to assess hip abductor strength. During the strength test, the participant was positioned in sidelying with the involved hip in 15° abduction. Independent-sample t tests were used to compare muscle volume and strength values between those with CHJP and asymptomatic controls. Results Compared to asymptomatic controls, women with CHJP demonstrated significantly increased gluteal muscle volume (228±40cm3 versus 199±29cm3; p=.032), but decreased hip abductor strength (74.6±16.8Nm versus 93.6±20.2Nm; p=.009). There were no significant differences in TFL muscle volume between the two groups (p=.640). Conclusions Women with CHJP appear to have larger gluteal muscles, but decreased hip abductor strength compared to asymptomatic controls.

“…15,[37][38][39]52 There are many exercises described in the literature to strengthen the GMin and GMed musculature, 39 some of which may not be appropriate for the older population (eg, single-limb deadlift and single-leg squat, 16 lunge, 16,18,20 prone plank 18 ). Thus, maximizing gluteal activation with exercises that can be performed easily in the home environment may be useful in the rehabilitation of gluteal musculature in an array of pathologies.…”

“…Many of these conditions, such as hip osteoarthritis 52 and lateral hip pain, 51 are accompanied by marked atrophy of both muscles, with particular susceptibility of the GMin. Atrophy of specific GMed and GMin segments (eg, anterior portion) also has been reported in healthy aging, 12 as well as in a population following total hip replacement 36 and in a sample of elderly cadavers, 23 with the anterior GMin being principally affected.…”

Study Design Controlled laboratory study, cross-sectional. Background The gluteus medius (GMed) and gluteus minimus (GMin) provide dynamic stability of the hip joint and pelvis. These muscles are susceptible to atrophy and injury in individuals during menopause, aging, and disease. Numerous studies have reported on the ability of exercises to elicit high levels of GMed activity; however, few studies have differentiated between the portions of the GMed, and none have examined the GMin. Objectives To quantify and rank the level of muscle activity of the 2 segments of the GMin (anterior and posterior fibers) and 3 segments of the GMed (anterior, middle, and posterior fibers) during 4 isometric and 3 dynamic exercises in a group of healthy, postmenopausal women. Methods Intramuscular electrodes were inserted into each segment of the GMed and GMin in 10 healthy, postmenopausal women. Participants completed 7 gluteal rehabilitation exercises, and average normalized muscle activity was used to rank the exercises from highest to lowest. Results The isometric standing hip hitch with contralateral hip swing was the highest-ranked exercise for all muscle segments except the anterior GMin, where it was ranked second. The highest-ranked dynamic exercise for all muscle segments was the dip test. Conclusion The hip hitch and its variations maximally activate the GMed and GMin muscle segments, and may be useful in hip muscle rehabilitation in postmenopausal women.

Atrophy of hip abductor muscles is related to clinical severity in a hip osteoarthritis population

et al. 2018

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.
