Background Virtual reality training (VRT) is engaging and may enhance rehabilitation intensity. Only one previous study has looked at its use to improve sitting balance after stroke. Objective To determine if supplemental sitting balance exercises, administered via VRT, improve control of sitting balance and upper extremity function in stroke rehabilitation inpatients. Design Assessor‐blinded, placebo‐controlled randomized controlled trial. Setting Stroke inpatient rehabilitation unit. Participants Seventy‐six participants (out of 130 approached) with subacute stroke who could not stand independently were randomized to experimental and control groups. Sixty‐nine completed the study. Interventions The experimental group did VRT that required leaning and reaching, whereas the control group had their trunk restrained and performed VRT that involved only small upper extremity movements to minimize trunk movement. Both groups performed 10‐12 sessions of 30‐45 minutes. Participants were assessed pre, post, and 1 month after the sessions by a blinded examiner. Outcome Measures Function in Sitting Test (FIST, primary outcome measure); Ottawa Sitting Scale; Reaching Performance Scale; Wolf Motor Function Test (WMFT). Results Thirty‐three participants completed the experimental intervention and 36 the control. Pre/post differences for FIST were 3.4 (confidence interval [CI] 0.5;6.3) for the experimental group and 5.3 (2.9;7.7) for the control group. There was a significant improvement over time (adjusted for multiple comparisons, P < .006) on most outcome measures except the WMFT Performance Time Scale (control group; P = .007) and grip strength ( P = .008); there were no differences between groups ( P > .006). Conclusions Siting balance outcomes were similar for both groups; therefore, this study does not support the use of sitting balance exercises provided via VRT for the rehabilitation of sitting balance after stroke. However, because it is only the second study to investigate VRT for sitting balance and upper extremity function, more research, using more challenging exercises and a greater treatment intensity, is required before definitive conclusions are made.
