Continuous activity monitoring in persons at high risk for diabetes-related lower-extremity amputation

This study evaluated the magnitude and location of activity of diabetic pat ients at high risk for foot amputation. Twenty subjects aged 64.6 +/- 1.8 y ears with diabetes, neuropathy, deformity, or a history of lower-extremity ulceration or partial foot amputation were dispensed a continuous activity monitor and a log book to record time periods spent in and out of their hom es for I week. The results indicate that patients took more steps per hour outside their home, but took more steps per day inside their homes. Althoug h 85% of the patients wore their phys ici an-approved shoes most or all of the time while they were outside their homes, only 15% continued to wear th em at home. Focusing on protection of the foot during in-home ambulation ma y be an important factor on which to focus future multidisciplinary efforts to reduce the incidence of ulceration and amputation. The ability to conti nuously monitor the magnitude, duration, and time of activity ultimately ma y assist clinicians in dosing activity just as they dose drugs.
