A behaviour change intervention promoting physical activity following dysvascular amputation: Protocol for a pilot...

Area of Science:

• Rehabilitation Medicine
• Physical Therapy
• Behavioral Science

Background:

• Diabetes-related lower limb amputation (LLA) significantly impairs quality of life and leads to sedentary behavior.
• Physical activity is crucial for managing chronic diseases and improving well-being, but individuals with LLA face challenges in participation.
• Existing interventions lack a peer-led approach for physical activity behavior change in this population.

Purpose of the Study:

• To assess the feasibility and optimize the design of a peer-led physical activity intervention for individuals with dysvascular LLA.
• To inform the development of a definitive randomized controlled trial (RCT).

Main Methods:

• A pilot randomized controlled trial (RCT) with a qualitative component.
• Intervention group received virtual peer coaching, web-based modules, and activity monitoring for 8 weeks.
• Feasibility, process, resource, management, and treatment indicators were collected, alongside primary outcomes (physical activity, self-efficacy) and secondary outcomes (mobility, quality of life).

Main Results:

• Feasibility data collection is ongoing.
• Primary outcomes (physical activity counts, self-efficacy) and secondary outcomes (mobility, quality of life) will be measured at baseline, post-intervention, and one month later.
• Qualitative interviews will explore intervention acceptability and feasibility.

Conclusions:

• This pilot study is essential for designing a definitive RCT.
• Findings will guide the effectiveness evaluation of a peer-led physical activity intervention for individuals with dysvascular LLA.
