Evaluating Pelvis Dynamics in Patients With Acetabular Labral Tears

Common forms of hip disease include labral tears, synovitis, chondromalacia, or femoroacetabular impingement [1, 2]. Most patients with one of these medical conditions seek treatment to alleviate the pain. However, in addition to the pain, dynamic control of hip joint movement may also be impaired. This impairment may result from damage to proprioceptive organs or alterations in sensory capability caused by inflammation. Reduced biofeedback can lead to a loss of joint control that may result in additional injuries due to excessive tissue strain or falling due to a loss of balance. Our hypothesis is that acetabular labral tears alter normal pelvic movement and reduce subject balance control placing the patient at increased risk for additional injuries.
