Textured Foot Orthotics on Dynamic Stability and Turning Performance in Parkinson's Disease.

Textured Foot Orthotics on Dynamic Stability and Turning Performance in Parkinson's Disease. J Mot Behav. 2019 Jul 17;:1-8 Authors: Robb KA, Perry SD Abstract The purpose of this study was to facilitate sensory feedback, with textured foot orthotics, to evaluate dynamic stability and turning behavior in Parkinson's disease individuals. Seven participants with a diagnosis of idiopathic Parkinson's disease, aged 55-80 years old, participated in this study. Participants completed three testing sessions; baseline, 4 weeks post-baseline, and 5 weeks post-baseline. Three experimental conditions were tested: footwear only (F), footwear + non-textured orthotic (FO), and footwear + textured orthotic (FOT). Kinematic, kinetic, and video data were collected during the steps preceding a turn task. Variables of interest included dynamic stability (maximum mediolateral (ML), minimum ML, and ML range of the center of mass (COM)-base of support (BOS) relationship) and turning performance (gait velocity and step count). There was a statistically significant increase in maximum ML COM-BOS distance (week 4 [0.1298 m ± 0.054] compared to week 0 [0.1069 m ± 0.050] p = .0076), and a significant decrease in step count (week 0-F [5.52 steps ± 1.08] to week 0-FO [5.23 steps ± 0.87] p = .0296) and (week 4-FO [5.24 steps ± 1.31] to week 4-FOT [4.67 steps ± 0.76] p = .0004). Textured foot orthotics modified dynamic stability and turn...
