背景：臀肌活性减弱的患者和运动员被认为患有“臀肌抑制”。这可能是关节源性神经肌肉抑制的一个组成部分，这在膝关节中已得到充分记录，并推广到所有关节。虽然有关臀肌抑制的临床证据有所增加，但支持性研究并不存在。本研究调查了在功能性髋关节伸展任务期间，在关节内灌注液体后髋部是否发生关节源性神经肌肉抑制。方法：在生物力学实验室（对照）和医院环境（干预）中收集数据。九名健康个体（4M/5F）构成对照组。干预组包含 12 名患有髋关节病变的患者（4M/8F），需要进行磁共振关节造影（通过关节内液体注射进行关节囊扩张）手术。参与者在控制时间或注射前后进行骨盆桥（PB）和主动髋部伸展（EXT）。双侧收集臀大肌 (GM) 的峰值肌电图。结果：本研究的结果为功能性任务期间髋关节内液体滴注后的关节炎抑制提供了实质性支持。双向重复测量方差分析揭示了会话交互效应的显着分组（PB，EXT：受影响/未受影响 = 0.0192/0.9654 P=0.05，
Background: Patients and athletes with diminished gluteal muscle activation are thought to have 'gluteal inhibition'. This may be a component of arthrogenic neuromuscular inhibition, which has been well documented in the knee and generalized to all joints. While clinical evidence surrounding gluteal inhibition increases, supportive research is non-existent. This study investigated whether arthrogenic neuromuscular inhibition occurred about the hip following instillation of intra-articular fluid during functional hip extension tasks.Methods: Data was collected in a biomechanics laboratory (control) and hospital setting (intervention). Nine healthy individuals (4M/5F) comprised the control group. The intervention group contained twelve patients (4M/8F) with hip pathology requiring a magnetic resonance arthrogram (capsular distension via intra-articular fluid injection) procedure. The participants performed a pelvic bridge (PB) and active hip extension (EXT) before and after the control time or injection. Peak EMG from the gluteus maximus (GM) was collected bilaterally.Findings: The findings of this study provide substantial support for arthrogenic inhibition following hip intra-articular fluid instillation during functional tasks. Two-way repeated measures ANOVA revealed a significant group by session interaction effect (PB,EXT: affected/unaffected = 0.0192/0.9654 P=0.05,
