1 Trial of Wii TM in Stroke- TWIST

2 NIHR Statement This presentation summarises independent research funded by the National Institute for Health Research (NIHR) under its Research for Patient Benefit (RfPB) programme. (Grant reference: PB-PG ) The views expressed in this publication are those of the authors and not necessarily those of the NHS, NIHR or Department of Health. Trial registered with ISRCTN and UK CRN

3 Rationale for TWIST 70% arm weakness post stroke 1 Physical therapy: evidence for high intensity, repetitive and task specific training 2 50% of patients do not get PT needed 31% of patients do not adhere to exercises 4 1.Royal College of Physicians.

4 Virtual Reality (VR) and Arm Function after Stroke Systematic review 2014: 24 RCTs (N = 626) 4 Significant effect for body functions and activity for VR therapy compared to conventional therapy VR rehabilitation moderately improves outcomes in adults post stroke 1 trial using Nintendo Wii TM Sports for upper limb rehab: N=18, no adverse side effects, improvement on WMF mean motor function (7s) 5 4.

5 Design of TWIST 1. RCT (single-blinded, 10 centres) Primary objective: Does six weeks of daily Wii TM Sports exercise improve arm function after stroke in comparison arm exercises, both at home? Secondary objectives: Arm function at 6 months, Occupational performance, Quality of Life, Adverse effects 2. Qualitative study Factors that influence use of Wii TM for participants and carers in practice? 3. Cost Effectiveness Analysis

6 Intervention Wii TM sports games of participants choice for 6 weeks in seated position up to 45 minutes per day at home Control Participant tailored arm exercise for 6 weeks in seated position up to 45 minutes per day Both groups continued usual therapy and were followed up at 6 week and 6 months

Outcome measures RCT Primary Outcome Measure: Action Research Arm Test Secondary Outcome Measures Canadian Occupational Performance Measure

7 Outcome measures RCT Primary Outcome Measure: Action Research Arm Test Secondary Outcome Measures Canadian Occupational Performance Measure Stroke Impact Scale EQ 5D Motor Activity Log (6 month only) Baseline data: stroke severity, impairment, arm strength, demographic data, use of Wii TM

8 Inclusion Criteria New stroke within last 6 months Aged 18 years or older Living in suitable environment Weakness in affected arm (MRC<5 in any joint plane of movement) due to stroke Exclusion Criteria Co-morbidities which impair ability to participate Symptomatic Shoulder Subluxation Pacemaker or ICD device Consideration of other interventional studies in line with Stroke Research Network guidance Able to manipulate Wii TM control remote Able to understand and follow 2 stage commands and give written or verbal consent

10 Analysis Main RCT, groups stratified by ARAT, previous use of Wii TM and centre allocation Primary outcome ARAT analysis of covariance Minimum of 99 participants per group, 80% power, with 5% type one error and two-sided significance test Health Economics analysis- QALYs, annuitised cost of Wii TM over 3 years, therapy standard costs Qualitative study-thematic analysis

11 Participant numbers 6027 participants screened 338 met inclusion criteria (5.6%) 98 declined to participate (29%) 235 participants randomised 209 completed all 3 study visits

17 Safety 46 serious adverse events (SAEs) None were treatment related 13 were readmission with recurrent stroke event 22 admissions to hospital for other reasons (myocardial infarction, fast atrial fibrillation, urosepsis, cellulitis, fall, pacemaker insertion and fractures) 11 other significant medical events

18 Exercise Time Outcome Mean N of days completed Wii TM Control P value Minutes of exercise per day 37.3 (14.3) 31.7 (16.1) Total amount of exercise 1020 (721) 998 (554) 0.805

19 Cost effectiveness analysis Outcome in Mean (SD) Wii TM Control NIHS costs 660 (848) 495 (377) Social Care Package Cost 317 (1218) 207 (641) Aids and appliances 18 (87) 28 (105) Wii TM cost Total 1106 (1656) 730 (829) QALY in years (0.115) (0.101)

20 Conclusions: Wii Sports TM Improved arm function at 6 weeks but not superior to arm exercises in our study group No serious adverse events Well tolerated by participants More costly than arm exercises Limitations of study: Blinding of researchers and participants Relatively young study group ARAT ceiling effect Duration of exercise
