On the Move: Center and Home-Based Exercise to Enhance Mobility in Diabetic Foot Ulcer Recovery

Обзор

Foot ulcers and amputations are a common and feared complication for people with diabetes. People with a diabetic foot ulcer have a higher risk of dying within five years than people with diabetes without an ulcer. At least one in four people with a new diabetic foot ulcer will die within five years, largely due to cardiovascular causes. The reasons for this increased mortality involve decreased mobility. People with a recently healed diabetic foot ulcer are considered "in remission" as opposed to "cured" because the underlying medical problems (e.g., peripheral neuropathy, peripheral arterial disease) which led to their ulcer are still present. Once in remission, the current standard of care is to slowly increase ambulation with appropriate footwear so as not to promote ulcer recurrence. The problem is that people rarely return to the recommended level of mobility. The ability to safely maintain mobility with aging is critical, as immobility is the leading cause of nursing home admissions. This is a clinical trial to test the feasibility and acceptability of an exercise regimen that transitions from in-person to home-based. The investigators will also assess if this exercise regimen can increase mobility and function without increasing diabetic foot ulcer recurrence by improving mobility, lower extremity strength, lower extremity tissue perfusion and glycemic control.

Подробное описание

Population: 60 Veterans with a healed foot ulcer in the last 3-15 months

Site: VA Maryland Health Care System (VAMHCS)

Study Duration: Approximately 3 years

Study Design: Randomized, outcome assessor blinded, clinical trial comparing a) a 12-week exercise regimen to b) standard of care

Objectives:

Primary: To assess the feasibility and acceptability of the intervention and estimate the effect of the intervention on 6-minute walk distance.

Secondary:

The effect of the intervention on other measures of mobility and function including gait speed, the Modified Physical Performance Test, steps per day and community mobility following the 12-week intervention and 6-months after to assess retention of the intervention.

The effect of the intervention on lower extremity strength, perfusion of the foot and glycemic control.

Treatment Regimens: 12-week exercise regimen to standard of care

Duration of Participant's Participation: Up to 10 months

Вмешательства

• Поведенческое 12-week exercise regimen
  Consistent with current physical activity recommendations for older adults, participants randomized in this arm will be prescribed 5 days/week of exercise, with seated cycling exercise performed on 3 days a week, and strength/balance exercise performed 2 days a week.
• Поведенческое 12-week standard of care
  Participants in this group will be provided with guidance on the current standard of care. This includes guidance that these patients should slowly increase ambulation with appropriately fitted footwear.
