N2 - OBJECTIVE: To elucidate the effect of step-synchronized vibration training using PDShoe on balance, gait, and quality of life in patients of Parkinson's disease (PD) with freezing of gait (FOG).MATERIALS AND METHODS: In a pilot study, 17 patients of PD with FOG were recruited for step-synchronized vibration training. The training involved 10 sessions of gait training over 2 weeks. Each session included three 6-min bouts of walking with step-synchronized vibration applied to the second metatarsal head and medial surface of calcaneus. Participants were assessed with the Unified Parkinson's Disease Rating Scale-III (UPDRS III), Timed Up and Go (TUG) test, Berg Balance Scale (BBS), Timed 10-Meter Walk Test, Freezing of Gait Questionnaire (FOG-Q), Falls Efficacy Scale-International (FES-I), and Parkinson's Disease Questionnaire-39 (PDQ-39). Measurements were collected pre-intervention, post-intervention, and at a 2-week follow-up. Friedman test followed by Wilcoxon signed-rank test were used for statistical analysis.RESULTS: All participants completed the intervention without any adverse effects. Fifteen participants reported for a follow-up evaluation 2 weeks after intervention. There was statistically significant improvement in UPDRS III (P = 0.044) and significant improvement in TUG test (P = 0.005), BBS (P = 0.026), FES-I (P = 0.041), and PDQ-39 (P = 0.021) scores between pre and follow-up evaluations. No significant changes were seen in FOG-Q and Timed 10-Meter Walk Test.CONCLUSION: Step-synchronized vibration is a novel intervention to improve balance, gait, motor features, and quality of life in patients of PD with FOG. Further research is warranted to confirm the results found in this pilot study.
