Little is known about muscle morphology in people with hip-related pain, without signs of femoro-acetabular impingement syndrome (FAIS). Identifying changes in hip muscle volume, fatty infiltrate and establishing relationships between muscle volume and strength, may provide insight into potential early treatment strategies.
To: (i) compare the volumes and fatty infiltrate of gluteus maximus, gluteus medius, gluteus minimis, tensor fascia latae and quadratus femoris between symptomatic and less-symptomatic sides of participants with hip-related pain; (ii) compare the volumes and fatty infiltrate of hip muscles between healthy controls and symptomatic participants; and (iii) explore relationships of hip muscle volumes to muscle strength and patient-reported outcome measures in people with hip-related pain.
Cross-sectional study.
Muscle volume and fatty infiltrate (from magnetic resonance imaging), hip muscle strength, patient-reported symptoms, function and quality of life (QOL) were determined for 16 participants with hip-related pain (no clinical signs of FAIS; 37±9 years) and 15 controls (31±9 years). Using One Way Analysis of Co-Variance tests, muscle volume and fatty infiltrate was compared between the symptomatic and less-symptomatic sides in participants with hip-related pain as well as between healthy controls and symptomatic participants. In addition, hip muscle volume was correlated with hip muscle strength, hip-reported symptoms, function and QOL.
No differences in all the studied muscle volumes or fatty infiltrate were identified between the symptomatic and less-symptomatic hips of people with hip-related pain; or between people with and without hip-related pain. Greater GMED volume on the symptomatic side was associated with less symptoms and better function and QOL (ρ=0.522-0.617) for those with hip-related pain. Larger GMAX volume was associated with greater hip abduction and internal rotation strength, larger GMED volume was associated with greater hip extension strength, and larger QF volume was associated with greater hip abduction strength (rho=0.507-0.638).
People with hip-related pain and no clinical signs of FAIS have hip muscle volumes that are not significantly different than those of matched pain-free controls or their less-symptomatic hip. Larger GMED muscle volume was associated with fewer symptoms and greater strength.

对于患有髋部相关疼痛但无股骨髋臼撞击综合征（FAIS）体征的人群，其肌肉形态的了解甚少。识别髋部肌肉体积、脂肪浸润的变化，并建立肌肉体积与力量之间的关系，可能有助于深入了解潜在的早期治疗策略。
（i）比较患有髋部相关疼痛的参与者有症状侧和症状较轻侧的臀大肌、臀中肌、臀小肌、阔筋膜张肌和股方肌的体积及脂肪浸润情况；（ii）比较健康对照组与有症状参与者的髋部肌肉体积及脂肪浸润情况；（iii）探讨患有髋部相关疼痛人群的髋部肌肉体积与肌肉力量及患者报告的结局指标之间的关系。
横断面研究。
对16名患有髋部相关疼痛（无FAIS临床体征；年龄37±9岁）的参与者和15名对照组（年龄31±9岁）测定肌肉体积和脂肪浸润（通过磁共振成像）、髋部肌肉力量、患者报告的症状、功能和生活质量（QOL）。使用协方差单向分析测试，比较患有髋部相关疼痛的参与者有症状侧和症状较轻侧之间以及健康对照组与有症状参与者之间的肌肉体积和脂肪浸润情况。此外，将髋部肌肉体积与髋部肌肉力量、髋部报告的症状、功能和QOL进行相关性分析。
患有髋部相关疼痛的人群中，有症状髋部和症状较轻髋部之间，以及有髋部相关疼痛者与无髋部相关疼痛者之间，在所研究的所有肌肉体积或脂肪浸润方面均未发现差异。对于患有髋部相关疼痛的人群，有症状侧更大的臀中肌体积与更少的症状、更好的功能和QOL相关（ρ=0.522 - 0.617）。更大的臀大肌体积与更大的髋外展和内旋力量相关，更大的臀中肌体积与更大的髋伸展力量相关，更大的股方肌体积与更大的髋外展力量相关（rho=0.507 - 0.638）。
患有髋部相关疼痛且无FAIS临床体征的人群，其髋部肌肉体积与匹配的无疼痛对照组或其症状较轻的髋部相比无显著差异。更大的臀中肌体积与更少的症状和更大的力量相关。
