Moving Mindfully for Freezing in Parkinsons

The investigators will modify and evaluate the feasibility of a mindfulness intervention among people living with Parkinson disease (PD) and freezing of gait (FOG). FOG is a severe motor disturbance that prevents people from stepping normally and is associated with anxiety, frustration, sedentary behaviors, poorer quality of life, and falls. Mindfulness-Based Stress Reduction (MBSR) is an evidence-based practice that creates a culture to reduce stress and anxiety by increasing conscious awareness and self-compassion. In this study, the investigators will develop a mindfulness-based walking intervention to address both mental health and mobility challenges that constitute FOG. This R34 feasibility study includes three aims to permit the development of a mind and body approach for FOG among people living with PD.

Aim 1: Create a Mindfulness-Based Walking Therapy (MBWT) program by modifying the MBSR standard protocol based upon feedback from an advisory group. An advisory group consisting of physical therapists, mindfulness instructors, research team members, 3-5 people with PD+FOG and care partners will modify the standard MBSR program over a twelve-week period to make it acceptable and feasible for people with PD+FOG and shift the focus from sitting, standing, or lying meditations to walking mediations.

Aim 2: Refine and standardize the MBWT protocol to ensure feasibility and acceptability through open pilot testing. Twelve participants with PD+FOG will participate in an open pilot of the MBWT program. The MBWT program will then be modified based on participant feedback to produce a standardized MBWT to use in Aim 3. Feasibility elements include meeting benchmarks for: 1) recruitment and randomization; 2) retention and satisfaction; 3) delivery of the intervention; 4) participant adherence using technology; 5) evaluating clarity and burden of outcome assessments; and 6) monitoring adverse events.

Aim 3: Conduct pilot randomized clinical trial to evaluate feasibility and acceptability of the standardized MBWT program. Using the standardized MBWT protocol produced from Aim 2, the investigators will randomize 24 people with PD+FOG to MBWT or usual care (i.e., medical management and FOG education), examining feasibility elements listed in Aim 2. The investigators will also conduct follow-up evaluations to monitor burden and continued usage of mindfulness. Aim 3 is under NCT05923229.
