Effects of a Novel, Inexpensive Device “Striker” On Spatio-Temporal GaitParameters in Individuals with Parkinson’s Disease

Abstract

Purpose: Problems with foot mechanics (insufficient heel strike) that are seen in individuals with Parkinson’s Disease (PD), result in landing with either the middle or front of the foot.  This altered pattern contributes to instability. Proper dorsiflexion of the foot resulting in heel strike can improve gait mechanics in PD, therefore the purpose of this research is to quantify the effects of a novel device on spatiotemporal gait parameters in individuals with PD. Methods: 11 individuals diagnosed with Parkinson’s disease (H & Y I -III) were recruited and screened using predetermined inclusion/exclusion criteria. Each participant wore a novel device, “Striker”. All participants were tested both with and without the device in a randomly chosen order during a Six Minute Walk Test and GAITRite Mat. A researcher developed a patient survey that was provided at the end of testing to assess feasibility and confidence using the “Striker”. Results: The Wilcoxon Sign Rank test was utilized to compare within-group differences indicating an improvement in cadence (p = 0.003) and the associated decline in gait velocity (p = 0.004) while using Striker. Conclusion: Significant change in cadence, while using “Striker” was associated with better biomechanics of the foot, initiating with a heel strike, thus decreasing the number of steps taken to cover the same distance. Additionally, most of the post-research surveys provided positive qualitative feedback. “Striker” may be used to improve heel strikes to decrease fall risk in individuals with PD.
