Comparison of combined virtual reality combined with standing balance training vs. standard practice in patients with hemiplegia: A single-blinded, randomized controlled trial.

ABSTRACT

OBJECTIVE: To determine whether virtual reality (VR)-based dynamic standing balance training improves three elements of sensory integration and investigate whether VR-based dynamic standing balance training results in improved outcomes, especially regarding balance and gait, compared to the standard training method. DESIGN: This single-blinded, randomized, controlled trial involved 30 patients with hemiplegia. The experimental (EG, n = 15) and control (CG, n = 15) groups received VR augmented-standing balance training or standard standing balance training, respectively, for 20 minutes, 5 days a week, for 3 weeks. The patients were assessed for primary (Sensory Organization Test [SOT] and the Berg balance scale [BBS]) and secondary (the functional reaching test and timed up-and-go test [TUG]) outcomes before and after training. RESULTS: From preintervention to postintervention, the BBS score (F = 26.295, p < 0.05), TUG score (F = 18.12, p < 0.05), mean score of conditions 2 (F = 4.36, p < 0.05) and 6 (F = 5.61, p < 0.05), and composite score of the SOT (F = 5.385, p < 0.05) in both groups were significantly improved. However, there was no significant difference between EG and CG (time*group p > 0.05). CONCLUSION: VR combined with standing balance training improved sensory integration, postural control, balance, and gait ability in patients with hemiplegia, reducing fall risk. However, outcomes were comparable to general balance training regarding balance and gait.
