Physical activity behavior change for older veterans after dysvascular amputation.
Determine the feasibility of using a physical-activity behavior-change (PABC) intervention for increasing physical activity and reducing disability in Veterans 1-5years following dysvascular lower-limb amputation (LLA).



Cross-over, feasibility trial SETTING: VA Geriatric Research Education and Clinical Center and Veterans Homes PARTICIPANTS: 32 Veterans with dysvascular LLA (1-5years after major LLA) INTERVENTION: The home-based study, using telerehabilitation technology, is intended to reduce participant burden by removing transportation and time barriers. Participants will be randomized into two participation periods of three months (Months 1-3 and 4-6). PABC intervention will occur Months 1-3 for GROUP1 and Months 4-6 for GROUP2. During PABC Intervention, participants engage in weekly video interaction with a physical therapist, who uses a collaborative approach to develop self-monitoring, barrier identification, problem solving and action planning skills to improve physical activity. GROUP2 will participate in a no physical activity intervention, attention control in Months 1-3. GROUP1 will have a no contact, intervention "wash-out" period in Months 4-6.



Feasibility will be determined using measures of 1) participant retention, 2) dose goal attainment, 3) participant acceptability, 4) safety, and 5) initial effect size. Effect size will be based on accelerometer-based physical activity and self-report disability using the Late-Life Function and Disability Index.



This study focuses on a prevalent and understudied population with low physical activity and high levels of disability due to dysvascular LLA. The results of this study will guide future development of targeted rehabilitation research to improve long term physical activity and disability outcomes.
