Abstract

Greater trochanteric pain syndrome (GTPS) is common, resulting in significant pain and disability. There is no condition specific outcome score to evaluate the degree of severity of disability associated with GTPS in patients with this condition. Objective To develop a reliable and valid outcome measurement capable of evaluating the severity of disability associated with GTPS. Methods A phenomenological framework using in-depth semi structured interviews of patients and medical experts, and focus groups of physiotherapists was used in the item generation. Item and format clarification was undertaken via piloting. Multivariate analysis provided the basis for item reduction. The resultant VISA-G was tested for reliability with the inter class co-efficient (ICC), internal consistency (Cronbach s Alpha), and construct validity (correlation co-efficient) on 52 naive participants with GTPS and 31 asymptomatic participants.
