OBJECTIVES: To determine whether 12-week home-based exergame step training can
improve stepping performance, gait and complementary physical and
neuropsychological measures associated with falls in Parkinson's disease. DESIGN:
A single-blinded randomised controlled trial. SETTING: Community (experimental
intervention), university laboratory (outcome measures). SUBJECTS: Sixty
community-dwelling people with Parkinson's disease. INTERVENTIONS: Home-based
step training using videogame technology. MAIN MEASURES: The primary outcomes
were the choice stepping reaction time test and Functional Gait Assessment.
Secondary outcomes included physical and neuropsychological measures associated
with falls in Parkinson's disease, number of falls over six months and
self-reported mobility and balance. RESULTS: Post intervention, there were no
differences between the intervention ( n = 28) and control ( n = 25) groups in
the primary or secondary outcomes except for the Timed Up and Go test, where
there was a significant difference in favour of the control group ( P = 0.02).
Intervention participants reported mobility improvement, whereas control
participants reported mobility deterioration-between-group difference on an
11-point scale = 0.9 (95% confidence interval: -1.8 to -0.1, P = 0.03).
Interaction effects between intervention and disease severity on physical
function measures were observed ( P = 0.01 to P = 0.08) with seemingly positive
effects for the low-severity group and potentially negative effects for the
high-severity group. CONCLUSION: Overall, home-based exergame step training was not effective in improving the outcomes assessed. However, the improved physical
function in the lower disease severity intervention participants as well as the
self-reported improved mobility in the intervention group suggest home-based
exergame step training may have benefits for some people with Parkinson's disease.
