Research summary
Femoroacetabular impingement (FAI) is increasingly recognized as a cause of groin/hip pain in young active adults (Reiman & Thorborg, 2015). This is thought to be due to differing shapes of either the hip ball and/or socket causing damage to the surrounding soft tissues \n\nLoss of strength has been identified as an impairment with patients with Femoroacetabular impingement, along with pain and loss of movement. (Casartelli et al., 2011; Nepple et al., 2015a), \n\nThe relationship between strength and symptoms in people with Femoroacetabular impingement compared to people without femoroacetabular impingement has not yet been described. In order to assist in the development of more effective rehabilitation/conservative treatment strategies, this relationship needs defining\n\nCurrently, surgery is the most commonly reported intervention although conservative measures, of which physiotherapy is the most common have been reported. This often consists of strengthening exercises of the hip muscles (Emara et al., 2011; Loudon & Reiman, 2014). \n\nThis study will give more detailed information on which muscles are weak around the hip in people with Femoroacetabular impingement and how this links to their symptoms. This research would inform physiotherapists on which muscles need targeting in conservative management sessions and future studies could compare the effectiveness of conservative and surgical approaches.\n\nWe propose to recruit patients with Femoroacetabular impingement to a case controlled study to evaluate if strength deficits exist in patients with Femoroacetabular impingement compared to matched controls. The relationship between any strength deficits and symptoms, measured on patient reported outcome scores will be explored. \n\nThe primary outcome will be strength using a hand held muscle dynamometer, using a standardized testing procedure (Thorborg et al., 2010) of the symptomatic limb in people with Femoroacetabular impingement. A secondary outcome will measure the degree of symptoms experienced, using the International Hip Outcome Tool (IHOT) 12 questionnaire.
