A Novel Digital Music-based Autonomous Personalized Walking Intervention to Improve Gait and Walking Automaticity in Parkinson Disease
Purpose
The purpose of this research study is to examine the effects of a 3-month personalized community-based walking program called MyMusiQ. The study uses music cues delivered through a digital device in people with Parkinson disease (PD). The investigators want to know if personalized music cueing through the digital device can improve walking quality, walking ability, daily walking amount and intensity, and quality of life, while helping walking feel more automatic and require less mental effort. Participants will take part in this research study for approximately 18 weeks in total. During this time, participants will complete 4 study visits at designated research centers at Boston University, Washington University in St. Louis, or the University of Utah, depending on the site of enrollment.

Detailed Description
The overall goal of this 3-month single-arm multi-center repeated baselines study (N=162) is to examine the effects of a personalized closed-loop music-based digital gait intervention on improving gait quality, capacity, real-world walking performance, and gait automaticity in Parkinson disease (PD). This study builds on a stepwise investigation beginning with a proof-of-concept feasibility study (N=23) followed by a 6-week randomized controlled trial (RCT; N=44). This mechanistic-focused study will examine the substrates of a personalized approach that underlie changes in walking outcomes, as well as identify determinants that determine responsiveness to the intervention. This study is a critical next step to elucidate mechanistic understanding of closed-loop personalized gait approaches and to determine those with PD who benefit most. The main aims of this mechanistic study seek to examine whether a personalized closed-loop gait intervention improves gait quality, walking capacity, and real-world walking performance beyond baseline variability, and to assess how personalized features influence targeted gait outcomes (Aim 1). Additionally, this study will investigate the effects of the intervention on improving gait automaticity (Aim 2), and identify baseline determinants that predict responsiveness and durability to the intervention on walking capacity (Aim 3). The investigators hypothesize that the intervention will meaningfully improve gait quality (speed, stride length), walking capacity (6-Minute Walk Test), and real-world walking performance (walking intensity and amount) during cued and uncued walking during and after intervention. Furthermore, they hypothesize improvements in gait automaticity (reduced gait variability, dual-tasking costs) following the intervention, and that individuals with worse baseline cognitive-motor capacities may benefit more. This study will utilize a digital music device (MedRhythms, Inc., Portland, ME). To examine the effects of the intervention, the investigators will use clinical measures of motor and gait function, and quantified movement data on walking using wearable sensors. This study will be implemented by carrying out the following study visits: (1) Primary screen over the phone, (2) In-Person Screening and Baseline Assessment #1, (3) Baseline Assessment #2 (2-3 weeks after Baseline Assessment #1) (4) Personalized, Closed-Loop Music-Based Gait Intervention (3 months) (5) Post-Intervention Assessment (immediately after the intervention, about 3 months), and (6) Durability / Follow-Up Assessment (about 1 month post-intervention). Altogether, these procedures may take about 4 months.
