RESUMO
This randomised controlled and double-blinded pilot study evaluated if interactive virtual reality balance related games integrated within conventional rehabilitation sessions resulted in more superior retraining of dynamic balance compared to CR after stroke. 19 subjects diagnosed with a recent episode of stroke were recruited from a local rehabilitation hospital and randomly assigned to either a control or an experimental group. Subjects in the control groups underwent 60 minutes of conventional rehabilitation while those in the experimental groups underwent 40 minutes of convention rehabilitation and 20 minutes of self-directed virtual reality balanced rehabilitation. Functional Reach Test, Timed Up and Go, Modified Barthel Index, Berg Balance Scale, and Centre of Pressure of subjects in both groups were evaluated before and on completion of the rehabilitation sessions. Results indicate that the inclusion of interactive virtual reality balance related games within conventional rehabilitation can lead to improved functional mobility and balance after a recent episode of stroke without increasing treatment time that requires more health professional manpower.
RESUMO
OBJECTIVE: The prospective pre-post control study was designed to evaluate the effect of introducing balance-focused interactive virtual-reality games to community-dwelling older women to improve their agility, balance and functional mobility. METHOD: The study was set in a senior citizens' club in Cheras, Kuala Lumpur, Malaysia. The participants were 36 community-dwelling older women. Participants were randomly divided into either a group undertaking balance-focused virtual-reality games or a group doing therapeutic balance exercises. The program lasted 6 weeks and was conducted twice a week for 40 min during each session. As the main outcome measures, the results of the Ten Step Test (TST), postural sway (overall performance index, OPI) and the Timed Up and Go test (TUG) were measured pre- and post-intervention to evaluate agility, balance and functional mobility, respectively. RESULTS: Although both groups improved in OPI (F = 4.63, p < 0.001), TST (F = 46.15, p < 0.001) and TUG (F = 52.57, p = 0.03), combined time and group interaction only improved in the TUG (F = 4.54, p < 0.05). No significant differences between the two groups were found in terms of TST (F = 0.02, p = 0.86), OPI (F = 0.66, p = 0.42), and TUG (F = 0.11, p = 0.74). CONCLUSION: Older people could improve their agility, balance and functional mobility by complementing therapeutic balance exercises with active participation in interactive virtual-reality games at home or in the community.
