Research summary
Chronic groin pain is a common clinical entity. There are many potential causes of chronic groin pain, muscular and articular, which often co-exist. There are a number of publications reporting the femoroacetabular impingement, a common articular pathology of the hip joint, being one of the common causes of groin pain.
There have been a small number of publications suggesting that pelvic girdle muscle imbalance follows a consistent pattern in participants with chronic groin pain. The aim of this study is to analyse the kinematic and electromyographic data of patients diagnosed with femoroacetabular impingement to establish the biomechanical characteristics of injured subjects with respect to controls and to patients with muscular groin symptoms, whose data have previously been collected and database built.
The participants will be recruited from NHS Orthopaedic Surgeries and will include approximately 20 adult and adolescent patients diagnosed with femoroacetabular impingement and healthy controls. They will be asked to sign a written consent, complete the medical history questionnaire and undergo clinical tests. They will then be asked to perform a series of simple movements, while the kinematic and electromyographic data will be collected by the Coda Motion System (Codamotion Cx1 sensor units, Charnwood Dynamics, Rothely, Leicestershire) and surface EMG device (Noraxon Telemyo 2400T, Scottsdale, Arizona, USA).
The outcome data will include muscle activity of relevant pelvic girdle muscles as well as information about the lower limb movements. It is expected, that we will observe a common pattern in muscle activation in symptomatic participants, which might be associated with alterations of the lower limb kinematic and will significantly differ from healthy controls. The group outcomes will help to better understand the underlying mechanisms of CGP and, particularly, femoroacetabular impingement as well as developing an effective and holistic rehabilitation protocols for these patients.REC name
