Low-load Resistance Training With Blood Flow Restriction in People With

Status Recruiting

Clinical Trial Summary

The study's objective is to determine the feasibility of low-load resistance training with blood flow restriction in people who have advanced Parkinson's disease and impaired mobility using a mixed-methods convergent parallel design in a single cohort. The study's long-term goal is to develop clinically feasible exercise interventions that are effective at improving mobility, participation, and quality of life for people with advanced Parkinson's disease.

Clinical Trial Description

This study will use a mixed-methods convergent parallel design to determine the feasibility of low-load BFR training in 20 people with advanced PD symptoms and impaired mobility (Hoehn and Yahr Stage [H&Y] 3-4). All participants will receive low intensity resistance training (20-30% of 1RM) with BFR targeting knee extensor, ankle plantarflexor, and elbow extensor muscles 2x/week for 8 weeks. Intervention will be delivered by a physical therapist with specialized training in BFR. Pre-defined feasibility criteria will be assessed in the primary aim. Outcomes assessed before and immediately after the 8-week intervention will include quantitative muscle strength and mobility assessments, and quantitative and qualitative data on health-related QOL. Aim 1: Determine low-load BFR training feasibility based on the following quantitative and qualitative criteria: 1) enrolling 20 participants, 2) retaining ≥80% participants, 3) obtaining ≥80% intervention adherence, 4) having no serious intervention-related adverse events, and 5) quantitatively and qualitatively measured acceptability. Aim 2: Determine changes in 1) knee extensor, ankle plantarflexor, and elbow extensor muscle strength using fixed myometry and 2) instrumented functional mobility (30-second Sit-to-Stand, Timed up and Go, self-selected walking speed, and Berg Balance Scale) using a system of inertial measurement unit wearable sensors. Exploratory Aim: Understand health-related QOL changes using the Parkinson's Disease Questionnaire-39 (PDQ-39) and semi-structured interviews to elucidate how components of the intervention translate into QOL changes through a mixed-method analysis of PDQ-39 constructs of mobility, activities of daily living, emotional well-being, social stigma, social support, cognition, communications, and bodily discomfort. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
