Study Protocol of “Find Technology”: a randomised control trial investigating the feasibility and efficacy of controller-free interactive digital technology in an inpatient stroke population

Background: Stroke is a frequently occurring event, often leaving a legacy of high burden. Activity in rehabilitation has the potential to improve physical outcomes, but the dose of such rehabilitation is typically poor. The aim of this study was to determine if new technology using controller-free games may increase client engagement, activity levels and physical outcomes.

Methods/design: In an RCT design, clients with recent stroke in an acute hospital setting will be allocated to either intervention (program based on stroke-specific software utilising controller-free motion capture software and commercially available hardware) and a 1:1 session of individualised therapy OR control situation (group exercise session) and a 1:1 individualised therapy session. Matched levels of time spent will be spent for the intervention and control. All participants will undergo a measurement session at study entry, and one after an 8-week period or prior to discharge if sooner, by a physiotherapist blinded to group allocation measuring upper and lower limb function, balance and mobility. As well, pain, fatigue, enjoyment, perception of benefits and ease of use of the system will be measured at each session.

Differences in activity during the week and while in therapy will be compared using t-tests. Repeated measures analysis of variance will be used to compare changes over time and between group (intervention versus control). Sample size calculations require recruitment of 74 participants.

Discussion: This study will provide quantifiable information regarding the differences in activity levels and outcomes from using controller-free video game technology in rehabilitation compared to usual rehabilitation.
