Towards development of a core outcome set in proximal hamstring tendinopathy - A systematic review of measurement instruments and their clinimetric properties

Abstract

ObjectiveTo find measurement instruments for proximal hamstring tendinopathy, map them to outcome domains, and evaluate their measurement properties. MethodsThere were three phases. Phase one involved a search of MEDLINE, CINAHL, EMBASE, SPORTSDISCUS and PUBMED (February 2022) to identify measurement instruments used in proximal hamstring tendinopathy research. In phase two we mapped these measurement instruments to the International Tendinopathy Scientific Consensus (ICON) core outcome domains. The third phase involved conducting a second search (same databases/census date) to identify studies that evaluated measurement properties of measurement instruments in participants with proximal hamstring tendinopathy. Measurement properties were then evaluated following the Consensus-based-Standards for the Selection of Health Instruments methodology —including risk of bias assessment and synthesis of findings. ResultsTwenty-eight different measurement instruments were identified in phase one. These were mapped to six of nine ICON domains in phase two. In phase three, there was only one instrument that had been evaluated for its measurement properties (4 studies, n = 302) – the Victorian Institute of Sport Assessment – Proximal Hamstring Tendinopathy (VISA-H). For the VISA-H there was moderate-quality evidence of sufficient construct validity, low-quality evidence of sufficient responsiveness, reliability and measurement error, very low-quality evidence of sufficient relevance and comprehensibility and very low-quality evidence of insufficient comprehensiveness. ConclusionThe VISA-H – mapped to the ICON disability domain – is the only one of the 28 different measurement instruments identified that was validated in this population. Caution in applying it is warranted given it is supported by lower quality evidence.
