Physical Activity Behavior Change for Older Adults After Dysvascular Amputation (PABC)
Physical Activity Behavior Change for Older Veterans After Dysvascular Amputation
Panoramica dello studio
Stato
Descrizione dettagliata
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:
- participant retention
- dose goal attainment
- participant acceptability
- 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.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Early PABC Intervention
GROUP 1 will participate in the Physical Activity Behavior Change (PABC) intervention phase during the first 3 months.
GROUP 1 will then participate in a non-exercise control phase during the second 3 months.
|
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.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Retention Rate
Lasso di tempo: 3 months
|
Retention rate will be measured as the percent of participants enrolled in the intervention who complete the intervention.
|
3 months
|
|
Dose Goal Attainment
Lasso di tempo: 3 months
|
Dose goal attainment will be measured as the percent of participants in the intervention phase of the study who meet the dose goal of an average 3% increase in daily steps.
|
3 months
|
|
Acceptability
Lasso di tempo: 3 months
|
Acceptability will be measured using the mean score of the Intrinsic Motivation Inventory - Interest / Enjoyment Subscale.
The scores range from 1 to 7, with higher numbers indicating higher acceptability, and a null value of 5.0.
|
3 months
|
|
Study-Related Adverse Events
Lasso di tempo: 3 months
|
Safety will be assessed as differences in rates of study-related adverse events between GROUP 1 and GROUP 2 during the first three months, when GROUP 1 is in the intervention phase and GROUP 2 is in the non-intervention control phase.

Accelerometer-Based Physical Activity
Lasso di tempo: 3 months
|
Physical activity counts will be measured using a waist-mounted accelerometer-based physical activity monitor (Actigraph).
The outcome will be average daily physical activity counts.

Late Life Function and Disability Scale, Frequency
Lasso di tempo: 3 months
|
The Late Life Function and Disability Scale (LLFDSI) will be used to assess the participant-reported disability at each test point.
Scores range from 0 to 100, with higher scores indicating higher disability.
