  Purpose
The objective of this study is to examine the feasibility of using a collaborative-care, home-based rehabilitation program to improve functional outcomes for people recovering from lower limb amputation caused by vascular problems and/or diabetes complications. The primary hypothesis is that the rehabilitation program will result in greater improvements in performance-based and participant-reported measures of physical function, compared to standard of care after outpatient rehabilitation.

Arms Assigned Interventions
Experimental: Exercise, activity, and self-management
Exercise, Walking Program, and Health Self-Management Support. Participants will be visited at home once monthly and contacted by phone once weekly over 12 weeks to deliver the interventions.
Behavioral: Exercise
Exercise will target muscle strength and joint mobility impairments and will be delivered over a 12 week period.
Behavioral: Walking Program
A walking program will be established with the goal of participants walking at least five days per week. Duration of program is 12 weeks.
Behavioral: Health Self-Management Support
Health self-management support will be delivered with weekly meetings between the researcher and participant over a 12-week period.
No Intervention: Home and phone visit
No intervention will be applied. Participants will be visited at home once monthly and contacted by phone once weekly over 12 weeks to monitor health status.
