IntroductionStroke survivors are commonly at risk of functional decline, which increase their dependency in activities of daily living and eventually affects their motivation level, self-efficacy, and quality of life. Circuit exercise has been shown to be useful in enhancing functional performance and quality of life of chronic stroke survivors. There is a need to review the existing "usual circuit exercise" and develop a better approach, such as game-based circuit exercise. Training in enriched and fun environment may possibly further promote neuroplasticity. However, evidence on inducing fun element in the existing circuit exercise among stroke survivors is limited. Also, no studies are available to date which report the benefit of circuit exercise on stroke survivors' self-efficacy and motivation level. Therefore, this study aims to assess the effectiveness of game-based circuit exercise in comparison to conventional circuit exercise on functional outcome (lower limb strength, postural stability and aerobic endurance), motivation level, self-efficacy and quality of life among stroke survivors. This study also aims to assess whether the outcomes gained from the 2 interventions could be sustained at week 12 and 24 post-trial.MethodsThis is an assessor-blinded randomized control trial comparing 2 types of intervention which are game-based circuit exercise (experimental group) and conventional circuit exercise (control group). Based on sample size calculation using GPower, a total number of 82 participants will be recruited and allocated into either the experimental or the control group. Participants in the experimental group will receive a set of structured game-based exercise therapy which has the components of resistance, dynamic balance and aerobic exercises. While participants in the control group will receive a conventional circuit exercise as usually conducted by physiotherapists consisting of 6 exercise stations; cycling, repeated sit to stand, upper limb exercise, lower limb exercise, stepping up/down and walking over obstacles. Both groups will perform the given interventions for 2 times per week for 12 weeks under the supervision of 2 physiotherapists. Outcomes of the interventions will be measured using 30-second chair rise test (for lower limb strength), Dynamic Gait Index (for postural stability), 6-minute walk test (aerobic capacity), Intrinsic Motivation Inventory questionnaire (for motivation level), stroke self-efficacy questionnaire (for self-efficacy) and Short Form-36 quality of life questionnaire (for quality of life). All data will be analyzed using descriptive and inferential statistics.DiscussionThis study will provide the information regarding the effectiveness of including game elements into circuit exercise training. Findings from this study will enable physiotherapists to design more innovative exercise therapy sessions to promote neuroplasticity and enhance functionality and quality of life among stroke survivors under their care.Trial RegistrationAustralian New Zealand Clinical Trials Registry, ACTRN 12621001489886 (last updated 1/11/2021).Copyright © 2022 the Author(s).
