DESCRIPTION (provided by applicant): Effect of femoroacetabular impingement (FAI) on hip motion in young adults Femoroacetabular impingement (FAI) is an increasingly recognized source of hip pain in young adults and has been implicated as a cause of labral injury and hip osteoarthritis (OA). FAI is a structural abnormality of the acetabulum ("pincer" FAI) or femur ("cam" FAI) which results in impingement between the acetabulum and femur during hip flexion and internal rotation. Current treatment for FAI includes surgical procedures to resect or reorient the femur or acetabulum or both. The number of FAI surgeries being performed in the US is estimated at 50,000 per year, with an annual growth rate of 15%, indicating that FAI is a growing health concern. While structure does contribute to hip pain, increasing evidence suggests that movement patterns also play an important role. The overall goal of this line of research is to improve treatment for hip pain, especially in young adults, prevent or slow the progression of chondral damage, and reduce the need for hip arthroplasty. The purpose of this project is to assess the movement patterns of people with painful FAI compared to people without hip pain and to test for pathology-specific and limb-specific differences in these patterns Identification of differences in movement patterns which may contribute to hip pain can improve non- invasive treatment for people with hip pain. To test for these differences, we will assess movement patterns using kinematic data collected during tasks including walking, running, stepping down and up, single leg squat, supine straight leg raise and prone hip extension in subjects with painful FAI and subjects without hip pain. We hypothesize that subjects with painful FAI will display movement patterns which are closer to the end of their available range of hip flexion, adduction and internal rotation than subjects without hip pain. We believe that these movement patterns contribute to a subject's hip pain. Based on the distinct patterns of joint damage between the two types of FAI, we hypothesize that people with pincer FAI will display different movement patterns than people with cam FAI. The knowledge gained from this research has the potential to redirect treatment for people with FAI by identifying movement patterns that could be targeted by inexpensive and non- invasive therapeutic interventions such as neuromuscular retraining.

描述（由申请人提供）：股骨髋臼撞击（FAI）对年轻成人髋关节运动的影响股骨髋臼撞击（FAI）是越来越多地被认为是年轻成人髋关节疼痛的原因，并被认为是盂唇损伤和髋关节骨关节炎（OA）的原因。FAI是髋臼（“钳形”FAI）或股骨（“凸轮形”FAI）的结构异常，其导致髋关节屈曲和内旋期间髋臼和股骨之间的撞击。目前FAI的治疗包括外科手术切除或重新定向 股骨或髋臼或两者。在美国进行的FAI手术数量估计为每年50，000例，年增长率为15%，表明FAI是一个日益增长的健康问题。虽然结构确实会导致髋关节疼痛，但越来越多的证据表明运动模式也起着重要作用。这一系列研究的总体目标是改善髋关节疼痛的治疗，特别是年轻人的治疗，预防或减缓软骨损伤的进展，并减少髋关节置换术的需要。本项目的目的是评估疼痛性FAI患者与无髋关节疼痛患者相比的运动模式，并测试这些模式中的病理特异性和肢体特异性差异。识别可能导致髋关节疼痛的运动模式差异可以改善髋关节疼痛患者的非侵入性治疗。为了测试这些差异，我们将使用在任务期间收集的运动学数据来评估运动模式，这些任务包括行走、跑步、下台阶和上台阶、单腿下蹲、仰卧直腿抬高和俯卧髋关节伸展，受试者患有疼痛性FAI和没有髋关节疼痛。我们假设，疼痛FAI的受试者将显示的运动模式更接近他们的髋关节屈曲，内收和内旋的可用范围比没有髋关节疼痛的受试者的结束。我们认为这些运动模式有助于受试者的髋关节疼痛。基于两种FAI之间关节损伤的不同模式，我们假设钳形FAI患者的运动模式与凸轮FAI患者不同。从这项研究中获得的知识有可能通过识别可以通过廉价和非侵入性治疗干预（如神经肌肉再训练）针对的运动模式来重新定向FAI患者的治疗。
