Subgrouping and targeted exercise programmes for knee and hip osteoarthritis

Background

Therapeutic exercise is a recommended core treatment for people with knee and hip osteoarthritis (OA), however, the observed effect sizes for reducing pain and improving physical function are small to moderate. This may be due to insufficient targeting of exercise to subgroups of people who are most likely to respond, and/or sub-optimal content of exercise programmes. This study aims to identify a) subgroups of people with knee and hip OA that do/ do not respond to therapeutic exercise, and to different types of exercise, and b) mediators of the effect of therapeutic exercise for reducing pain and improving physical function. This will enable optimal targeting and refining the content of future exercise interventions.

Methods

Systematic review update and individual participant data meta-analyses (PROSPERO: CRD42017054049). A previous review will be updated to identify randomised controlled trials that compare the effects of therapeutic exercise for people with knee and hip OA on pain and physical function, to a non-exercise control. Lead authors of eligible trials will be invited to share individual participant data. Trial- and participant-level characteristics (for baseline variables and outcomes) of included studies will be summarised. Meta-analyses will use a two-stage approach, where effect estimates are obtained for each trial and then synthesised using a random effects model (to account for heterogeneity). All analyses will be on an intention-to-treat principle and all summary meta-analysis estimates will be reported as standardised mean differences with 95% confidence intervals.

Status

Ongoing. 114 RCTs included in the systematic review, 61 trial leads have agreed, in principle, to share data.
