the lab/clinic: 3D motion capture video § Out the lab: self-reported subjective measures • Potential for [near] continuous, unobtrusive monitoring of movement: § Inertial measurement § Marker-less video tracking § Fabric sensors § Smartphone/watch integration
(less obtrusive) § Low power § More variables/measures • Leads to a challenge on the data side: § Data can be ’abstract’ – e.g. acceleration, pressure, bend angle § Lacks context – no observations § Data translated to clinically (or behaviourally) meaningful measures Movement Analytics: Overcoming these challenges to Monitor, Measure and Model Movement
in the UK have osteoarthritis [Versus Arthritis]. • Over 250,000 joint replacements are performed each year, primarily hip and knee [National Joint Registry]. Research projects: 1. OATech Network Data scoping project: Barriers and Opportunities for data sharing 2. Measuring compensatory movements using smartphone sensors (PhD project) 3. Pre-surgical planning for Total Hip Replacement.

and environments which act as exercise cues to help adherence to exercise • Use motion capture to map real movements onto an avatar • Biomechanical modelling that will adapt the exercise based on patient performance • Initial study: How accurately can people follow an avatar’s movements • Used step-timing and synchronisation.
