Finco MG, Cay G, Lee M, Garcia J, Salazar E, Tan TW, Armstrong DG, Najafi B. Taking a Load Off: User Perceptions of Smart Offloading Walkers for Diabetic Foot Ulcers Using the Technology Acceptance Model. Sensors (Basel). 2023 Mar 2;23(5):2768.
Design: Randomised Control Trial Subjects: 21 adults with DFUs (age 61.5 ± 11.8 years; 85.7% male). Methods: Participants were randomized to wear either: • Irremovable cast walker (Reference group) (n=11) • Removable cast walker (Control group) (n=8) • Smart removable walkers (smart boot) that provided feedback on adherence, walking steps and walking cadence (Intervention group) (n=9). Results: • Smart boot users reported that learning how to use the boot was easy (ρ =- 0.82, p≤ 0.001). • Participants who had lower cadence (ρ = 0.74, p < 0.001) or deeper ulcers (ρ = −0.55, p < 0.001) reported that the smart boot helped them follow physician orders. • Non-fallers, compared to fallers, reported the design of the smart boot made them want to wear it longer (p = 0.04) and it was easy to take on and off (p = 0.04) and would like to use it more in the future (ρ = 0.55) (all p < 0.001).
Key message: Smart offloading devices with a remote patient monitoring solution may help promote adherence among older adults to wear offloading boots prescribed for Diabetic Foot Ulcers.
