Physical Activity Behavior Change for Older Adults After Dysvascular Amputation

Physical Activity Behavior Change for Older Veterans After Dysvascular Amputation

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 31 (actual)
• Sponsor: VA Office of Research and Development · Federal
• Sex: All
• Age: 50 Years – 85 Years
• Healthy volunteers: Not accepted

Summary

This pilot study will use mobile-health technology to deliver an intervention designed for lasting physical activity behavior change. The study will assess the feasibility of using the Physical Activity Behavior Change(PABC) intervention for Veterans with lower limb amputation. This intervention will be delivered using wrist-worn wearable activity sensors and a home-based tablet computer to allow real-time physical activity feedback and video interface between the participants and the therapist.

Detailed description

This pilot study will assess the feasibility of using the Physical Activity Behavior Change(PABC) intervention for Veterans with dysvascular lower limb amputation. In addition, preliminary efficacy of the PABC intervention will be assessed using a two-group randomized cross-over design. Testing will occur at baseline (pre-intervention), three months (end of intervention), and six months. The primary aim is to determine feasibility of using the PABC intervention with Veterans who have dysvascular amputation by measuring: 1. participant retention 2. dose goal attainment 3. participant acceptability 4. safety The secondary aim is to preliminary assess efficacy of the PABC intervention by measuring accelerometer-based physical activity and self-report disability effect sizes.

Conditions

• Amputation
• Diabetes Mellitus, Type 2
• Peripheral Artery Disease

Interventions

Type	Name	Description
BEHAVIORAL	Physical Activity Behavior Change (PABC)	Home-based weekly sessions (30 min) using behavior change methods for promoting physical activity. Sessions will occur using home-based computer tablets for real-time video interface between the participant and therapist. Participants will wear wrist-mounted activity sensors with direct physical activity feedback during the intervention period to allow for behavioral feedback and action planning.
