Objectives: The goal of this study was to systematically review the effect of augmented reality (AR) rehabilitation in the recovery of upper and lower limb function in stroke patients.
Materials and Methods: Three electronic databases were searched from January 2010 to June 2019 using selecting keywords in English language, namely: PubMed (Medline), Web of Science (WOS), and Science Direct. Eligible studies included both randomized controlled trials and observational studies which evaluated the change of outcome.
Results: Twelve studies met the inclusion and exclusion criteria. Nine trials were conducted to patients of chronic periods (7 months to 5 years after stroke) and 3 ones were executed to patients of subacute stages (2 months to 3 months following stroke). All of the recruited patients are much older than 18 years old (mean age: 52.17 years old). ARs were provided in variety of interval and number, ranged from 60 minutes to 1200 minutes over 2 weeks to 8 weeks. Among them, there are 8 observational studies with pre/post intervention design for upper limb recovery and 4 studies including 2 randomized controlled trials and 2 non-randomized controlled trials for lower limb rehabilitation. First, in the pooled analysis of 8 observational studies, the effect of AR rehabilitation on the upper limb function was 0.557 (95% CI, 0.316 to 0.799, p < 0.05). The significant improvement was observed for motor impairment and upper extremity function (28.5%, p < 0.05 and 35.6%, p < 0.05, respectively) after using AR intervention. Second, the combined effect of AR rehabilitation on the lower limb function including both balance and gait function was 0.520 (95% CI, 0.039 to 1.001, p < 0.05). However, no significant difference was observed for only Berg Balance Scale and only Time Up and Go Test, respectively.
Conclusions: The current findings of this systemic review indicate that the AR rehabilitation is moderately more effective on improving function than conventional rehabilitation does for upper and lower limb in subacute to chronic stroke adult patients. |
