Consideration-of-concept of the VirtualRehab Platform for Delivery of Upper Limb Rehabilitation at Home for People Late After Stroke
Consideration-of-concept of the VirtualRehab Platform for Delivery of Upper Limb Rehabilitation at Home for People Late After Stroke
This study will deliver a 12-week exercise-based upper limb virtual reality, non-immersive, rehabilitation programme for stroke survivors. The aims are to:1. to assess the acceptability and usability of the VirtualRehab platform for delivery of stroke rehabilitation at home:
2. to find if stroke survivors adhere to 'prescribed' use of the VirtualRehab platform over a 12-week period; 3. to assess the viability of using randomised length of baselines and repeated measures during the intervention period to inform subsequent study to find the optimum therapeutic dose 4. to estimate how a 12-week period of using the VirtualRehab platform could change motor impairment and functional capacity.
Background and objectives:
This study is driven by the hypothesis that provision of task-orientated training via a non-immersive virtual reality platform enhances upper limb motor and neural function more than current routine physical therapy for people with stroke. Before this hypothesis can be tested in a randomised controlled clinical trial. If evidence of concept is found, then the next step is identification of the optimum therapeutic dose of exercised-based therapy delivered via the Virtualrehab Platform as a precursor to a clinical efficacy trial. The specific objectives of the study reported here were:
Design:
A series of replicated single case studies with an AB design (2.1). During the A, control, phase participants will not receive the experimental intervention. Participants will receive the experimental intervention during the B phase. At the beginning of the control phase, participants will complete the measurement battery. These will be the baseline-one measures. The measurement battery will be repeated at the end of the baseline phase (baseline-two) and at the end of the intervention phase (outcome). Progress measures will be made at the end of every week of the intervention (B) phase.
Both sets of baselines and the outcome measures will be taken in the Movement and Exercise Laboratory (MovExLab) at the University of East Anglia (UEA). Progress measures will be made in participants' homes. The control phase will last for a randomised period of between one and four weeks. The time period for the control phase will be decided for each participant by a randomised sequence generated before the study begins, by a researcher independent of the research team for this study. The intervention phase will last for 12 weeks. During the intervention phase, each participant will undertake weekly progress measures in their home. These will be administered by the researchers prescribing and monitoring training. At the end of the control and the intervention phase, all participants will participate in a 1:1 semi-structured interview with the researcher.
A group of adults without any reported neurological damage undertook the measurement battery to provide reference values. The measurement battery and progress measures are described below.
Stroke participants:
Inclusion criteria:
(A) Adults (18+); (B) At least six months after stroke; (C) A score of at least 19/33 on the Motricity Index elbow flexion and shoulder abduction section but unable to complete the Nine Hole Peg Test (9HPT) in 50 seconds or less with their more paretic upper limb.
