Feasibility of a Low-Intensity, Technology-Based Intervention for Increasing Physical Activity in Adults at Risk for...

Area of Science:

• Podiatry and Diabetes Management
• Behavioral Science and Health Technology
• Preventive Medicine and Public Health

Background:

• Diabetic foot ulcers (DFUs) affect 19-34% of adults with diabetes, increasing amputation risk and healthcare costs.
• Gradual increases in physical activity may help prevent DFUs.
• A low-intensity, technology-based intervention was developed to promote physical activity in adults at risk for DFUs.

Purpose of the Study:

• To examine the feasibility and acceptability of a technology-based behavioral intervention designed to increase physical activity in adults at risk for diabetic foot ulcers (DFUs).
• To assess the intervention's impact on physical activity levels, daily mobility, and glycemic control (A1C).

Main Methods:

• A mixed-methods study involving 12 participants at risk for DFU (66% female, mean age 59.9 years).
• Participants received in-person counseling and used an activity monitor and text messages for 2-3 weeks, followed by 8 weeks of monitoring.
• Assessments included accelerometer-measured activity, daily mobility, A1C, and treatment acceptability via questionnaires and interviews.

Main Results:

• The intervention demonstrated feasibility, with high attendance, activity monitor usage, and text message response rates.
• Treatment acceptability was high (average rating 4.79/5).
• Participants increased daily steps by 881.89 steps/day and showed a decrease in A1C by 0.33%; daily mobility did not significantly change.

Conclusions:

• A minimally intensive, technology-based intervention may be beneficial for increasing physical activity in individuals at risk for DFUs.
• Future research should compare this intervention to usual care.
• Participant feedback suggested improvements such as providing more physical activity information and addressing pain.
