Physical impairments and activity limitations in FAI
Femoroacetabular impingement (FAI) results from morphological hip abnormalities that abut the proximal femur against the acetabular rim. Impingement typically occurs in sports such as football and hockey where combined movements of hip flexion, adduction and internal rotation are commonplace. Whilst the jury is still out regarding surgical intervention, non-operative treatments outcomes need to be evaluated in order to guide the development of rehabilitation strategies. The following systematic review aimed to establish whether people with symptomatic FAI demonstrate physical impairments and/or disability, and whether treatment affects these parameters.
The most commonly reported physical impairment was decreased range-of-motion (ROM) into the direction of hip impingement. Furthermore, deficits in sagittal and frontal plane hip ROM during gait and stair climbing were reported, along with reductions in hip flexor and adductor muscle strength. Surgical interventions, whilst inconsistent, appeared to improve hip ROM during gait, along with increasing squatting depth.
Further studies investigating physical impairment are required to evaluate outcomes from surgical and non-operative interventions to inform rehabilitation protocols.
