Proximal control and lower extremity (LE) movement related to foot function may be an important factor for plantar fasciitis (PF) during running. This study aimed to investigate hip muscle activity and frontal plane LE kinematics during running between long-distance runners with and without PF. The electromyographic amplitude of the hip muscles (tensor fascia latae, gluteus medius, gluteus maximus) and frontal plane LE joint angles (ankle, knee, and hip range of motion during stance phase) of 30 habitually shod long-distance runners (15 with acute PF and 15 healthy controls) were simultaneously recorded using surface electromyography, 8 infrared cameras, and force plates while they ran barefoot at a speed of 3 to 3.67 m·s-1. Independent t test and 2-way analysis of variance were used to analyze the differences for dependent variables. The PF group had significantly lower tensor fascia latae (P = .040, effect size = 0.259) and gluteus medius (P = .014, effect size = 0.197) activation during the swing phase and gluteus maximus (P = .012, effect size = 0.207) activation during the stance phase compared with the control group. Moreover, the PF group showed significantly greater joint angular excursions of the contralateral pelvic drop (P = .049, effect size = 0.75), hip adduction (P = .019, effect size = 0.91), knee abduction (P = .040, effect size = 0.79), and rearfoot eversion (P = .004, effect size = 1.14) during the stance phase than the control group. Adding assessment of hip muscle activity and LE joint angles during running would be beneficial for evaluating runners with PF.
近端控制以及与足部功能相关的下肢运动可能是跑步过程中足底筋膜炎（PF）的一个重要因素。本研究旨在调查有和没有PF的长跑运动员在跑步过程中的髋部肌肉活动和额状面下肢运动学。使用表面肌电图、8台红外摄像机和测力板，同时记录了30名习惯穿鞋的长跑运动员（15名急性PF患者和15名健康对照者）在以3至3.67 m·s-1的速度赤脚跑步时髋部肌肉（阔筋膜张肌、臀中肌、臀大肌）的肌电幅度以及额状面下肢关节角度（站立期踝关节、膝关节和髋关节活动范围）。采用独立样本t检验和双向方差分析来分析因变量的差异。与对照组相比，PF组在摆动期阔筋膜张肌（P = .040，效应量 = 0.259）和臀中肌（P = .014，效应量 = 0.197）的激活明显较低，在站立期臀大肌（P = .012，效应量 = 0.207）的激活也明显较低。此外，PF组在站立期对侧骨盆下降（P = .049，效应量 = 0.75）、髋关节内收（P = .019，效应量 = 0.91）、膝关节外展（P = .040，效应量 = 0.79）和后足外翻（P = .004，效应量 = 1.14）的关节角度偏移明显大于对照组。在跑步过程中增加对髋部肌肉活动和下肢关节角度的评估，将有助于评估患有PF的跑步者。
