Weight Loss Intervention for Individuals With Lower Extremity Amputation (MOVE-LEAP)
The purpose of this study is to pilot test a program to help overweight and obese individuals with a lower extremity amputation (LEA) lose weight and become more physically active. The investigators will randomize approximately 30 individuals to either a self-directed weight loss program (n=15) or a coached weight loss program (n=15). The primary purpose of this pilot study is to determine if a home-based weight loss/physical activity (PA) intervention is feasible in individuals with a LEA. MOVE-LEAP is a 20-week program that involves 11 phone calls from a health coach and a single home visit by a physical therapist.
This pilot study aims to:
- test the feasibility of recruiting overweight/obese individuals with LEA into a randomized trial;
- assess whether the intervention can be delivered with high fidelity, and
- evaluate whether the intervention is acceptable to and safe as determined by participant feedback, participation and retention for outcome measures.

Behavioral: Coached group
Behavioral: Self-directed control group

Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment

- Feasibility (recruitment) [ Time Frame: During recruitment (expected duration of 12-15 months) ]Specific components include yield by method, recruitment rate, refusal rates and reasons, eligibility criteria (sufficient or too restrictive), staff time to compile mailings, respond to phone calls, etc.
- Feasibility (adherence) [ Time Frame: Baseline and follow-up assessments (all participants) and during intervention (intervention group only) (weekly, for 20 weeks) ]Specific components include % of randomized individuals who complete baseline and study exit visit (both groups), % of phone calls completed (intervention group), % goals completed (intervention group), completion of eating and activity logs (intervention group), amount of missing data on questionnaires (both groups), pedometer wear time (both groups)
- Fidelity and acceptability [ Time Frame: During intervention (weekly for 20 weeks, intervention group only) and at follow-up assessment (20-weeks follow-up) ]Fidelity will be assessed during coaching calls via fidelity checklists including key concepts covered, duration of phone sessions, audiotape review of calls. Acceptability of intervention will be assessed via a brief satisfaction survey and qualitative interviews. Acceptability in terms of safety will be assessed by the number of injuries and adverse events compared to expected rates.
- Secondary measures related to program effectiveness, including weight change, physical functioning, etc. [ Time Frame: Baseline and follow-up assessments (20-weeks, 12-months, and 18-months after randomization) ]Measures include weight, waist circumference, body composition (as measured by DEXA), diet (via a focused dietary recall), physical activity (via objective physical activity monitors and self-report measures), and physical functioning (e.g., 6-minute walk, get up and go, and self-report measures)
- Physical functioning [ Time Frame: Baseline and at follow-up assessments (20-weeks, 12-months, and 18-months after randomization) ]Physical functioning will be measured via a 2- and 6-minute walk, get up and go, and self-report measures
- Diet and physical activity [ Time Frame: Baseline and follow-up assessments (20-weeks, 12-months, and 18-months after randomization) ]Diet will be measured via focused 24-hour dietary recalls. Physical activity will be measured via objective physical activity monitors and self-report measures.

Participants randomized to the coached arm will receive the same educational and self-monitoring materials as the self-directed group. In addition, participants in the coached arm will receive 11 calls from a health coach and a single visit to their home by an exercise specialist.
Behavioral: Coached group
Participants randomized to the coached arm will receive 1) education and self-monitoring materials [e.g., a booklet, calorie count book, pedometer, and scale (if they do not have one)], 2) a home visit by an exercise specialist, and 3) 11 telephone calls (over a 20-week period) by a health coach who will utilize motivational interviewing techniques to help the participant set eating and activity goals and trouble shoot problems when they occur
Active Comparator: Self-directed
Participants randomized to the self-directed arm will receive the same educational and self-monitoring materials as the coached group, but no home visit and no coaching calls. They will be encouraged to make behavior changes on their own.
Behavioral: Self-directed control group
Participants randomized to the self-directed arm will receive the same educational and self-monitoring materials as the coached group [e.g., a booklet, calorie count book, pedometer, and scale (if they do not have one)], but no home visit and no coaching calls. They will be encouraged to make behavior changes on their own.
Participants randomized to the intervention arm will receive (1) a home visit by an exercise specialist and (2) a 20-week telephone-delivered weight loss program, modeled on the VA's Telephone Lifestyle Coaching Program (MOVE!TLC). All participants (both the coached arm and self-directed arm) will be mailed a MOVE-LEAP packet [containing eating and physical activity logs, information on how to set weight loss goals, suggestions for physical activity/exercise, dietary guides, etc.), a MOVE-LEAP handout booklet, calories counting book, a pedometer, exercise DVD, and a flip-booklet with exercises ("Exercise Guide for Persons with Limb Loss"). A bathroom scale will be provided for participants who do not already own one.
Participants in the coached arm will receive a home visit by an exercise specialist. This visit will occur 1-3 weeks after randomization. The exercise specialist will assess the participant's capabilities and interest regarding physical activity as well as his/her home environment for physical activity. Since each participant may have different physical capabilities and limitations, the type and intensity of physical activity will be tailored to each participant's preferences and their home and neighborhood/community environment and resources. If the participant is interested in performing physical activity outside their home, study staff will provide them with information about community resources for physical activities.
Participants in the coached arm will receive 11 calls by a study health coach. During the phone calls (weekly initially and then every other week), the health coach will review progress and help the participant to set "SMART" goals (Specific, Measurable, Attainable, Relevant and Time-limited) and will use motivational interviewing techniques to help the participant achieve those goals. Motivational interviewing is a style of counseling meant to increase participant engagement through strategic use of open-ended questions, reflective listening and positive affirmations. The study staff will review the participant's progress on his or her goals and help him or her problem solve to resolve challenges and modify goals as needed. During each session, the coach will discuss an educational topic relating to weight loss. Written materials on each topic are included the booklet.
