Micro-mobile Foot Compression and Diabetic Foot

Diabetic foot ulceration (DFU) is a common and largely preventable complication. While most
of these ulcers can be treated successfully, some will persist and become infected.
Ultimately, nearly one fifth of patients with infected lower-extremity diabetic ulcers will
require amputation of the affected limb.Prevention by identifying people at higher risk is
the key for better clinical management of such patients. It is not uncommon for patients
suffering from diabetes to have concomitant lower extremity edema or even venous
insufficiency and they subsequently may benefit from graduated compression. However, because
of the common association of peripheral arterial disease (PAD) in patients with diabetes,
most clinicians are reluctant to apply compressive dressings in fear of exacerbating the
symptoms of PAD and the possible resulting gangrene.

A novel micro-mobile foot compression device named Footbeat (AVEX, Inc.) offers alternative
means providing lower extremity compression. This device is portable and can be used in a
standard diabetic shoes on daily basis, which in turn may improve venous blood and relief
from concomitant lower extremity edema. In addition, potential improvement in lower extremity
blood flow in response to regular foot compression, could improve balance, gait, skin
perfusion, plantar sensation, and overall daily physical activities (e.g. number of taken
steps per day, duration of standing, etc).

The purpose of this study is to conduct an observational study with N=30 ambulatory patients
with diabetes and loss of protective sensation to assess whether this micro-mobile foot
compression device can help improving motor function, lower extremity perfusion, and vascular
health.
