ABSTRACT
OBJECTIVE:
To study effectiveness of and satisfaction with a virtual reality-based balance rehabilitation system (BioTrak) for patients with acquired brain injury (ABI). MATERIAL ANDMETHODS:
Ten patients with chronic hemiparesis (chronicity>6 months) following an ABI completed a 20-session programme using the balance reaching-task module of the BioTrak system. All patients were assessed at baseline, at the end of treatment, and one month later with the Berg Balance Scale (BBS), the Tinetti Performance-Oriented Mobility Assessment (POMA), and the computerised posturography tool NedSVE/IBV. The posturography study included analysis of sensory indexes, limits of stability, and rhythmic weight shift. The usability study was conducted using an ad hoc questionnaire.RESULTS:
Repeated measures ANOVA showed a significant improvement in BBS (P<.01), TBS (P<.01), vestibular index (P<.05), and anterior-posterior weight shift (P<.05); a trend in the same direction was also found for medial lateral weight shift (P=.059). The post-hoc analysis revealed significant improvement between the initial and final assessments for BBS, POMA and anterior-posterior weight shift control; gains remained a month after completing the programme. The system showed a high degree of usability in terms of presence, immersion and user-friendliness, and there was a significant absence of adverse effects.CONCLUSION:
Our results confirm the utility of virtual reality systems for balance rehabilitation in this population. Usability data suggest that BioTrak could be adapted for use in multiple rehabilitation settings by a high number of patients.
