    Abstract

    Gluteal tendinopathy (GT) is common and can be debilitating and challenging to manage. A lack of condition specific and appropriate outcome measures compromise evidence synthesis for treatment and limits clinical guideline development. Our objective was to develop a core outcome measurement set for GT (COS-GT). Participants were patients with GT and expert health professionals (HPs). A scoping review identified measures used in GT research, which were mapped to the nine International Scientific Tendinopathy Symposium Consensus core domains, and included in two surveys of HPs. The first survey identified the feasible and true measures for each domain. The second survey refined the list which a patient focus group then considered. Meeting online, HPs reached consensus (agreement ≥70%) on the most appropriate COS-GT measures. 34 HPs and seven patients were recruited. 57 measures were mapped to the nine core domains. Six measures did not proceed past survey one. Of those that progressed, none had adequate clinimetric properties for a COS-GT. Thus, participants decided on interim measures: the global rating of change, pain at night, time to pain onset with single limb stance, pain with stair walking, pain self-efficacy and hip abduction strength. HP participants additionally recommended that pain over the last week, the European Quality of Life-5 dimensions-5 levels and the Victorian Institute of Sport Assessment-Gluteal be considered in clinical trials, as they currently provide best easures of the relevant tendinopathy domains. In conclusion this interim COS-GT should guide outcome measure selection in clinical practice and future research trials in patients with GT.
