Abstrakt

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.

Experimental: Avex Footbeat
Subjects will receive a new pair of diabetic shoes with BOA shoelace closure and a pair of AVEX Footbeat insoles, which include a micro-mobile compression pump. The entire system is named 'intervention shoes' for simplicity. They will be instructed to wear the intervention shoes on daily basis for 4 weeks for duration of at least 4 hours per day.
Device: Avex Footbeat
Subjects will receive diabetic shoes equipped with Boa Technology shoelace system and Footbeat compression insoles, which for simplicity will be named intervention shoes. All participants will be asked to wear the intervention shoes for duration of 4-weeks on daily basis (minimum 4 hours per day). Daily use of the intervention shoes will be assumed to improve balance, mobility, plantar sensation, lower extremity edema, and lower extremity skin perfusion.

Resultat

Primära resultatåtgärder

1. Change in Balance From Baseline to 4 Weeks [baseline and 4 weeks.]

Balance will be quantified by measuring body sway in medial-lateral direction using a validated wearable sensors technology (Balansens, Biosensics LLC) and body sway change after 4-weeks of daily use of AVEX Footbeat will be assessed compare to baseline. Th unit of measurement is cm.

2. Change in Skin Perfusion From Baseline to 4 Weeks [Baseline and 4 weeks]

Skin perfusion was quantified using Skin Perfusion Pressure Test (SPP) at the lower extremities at baseline and at 4-week (end point). The measurement of SPP was done using a device called Sensilase PAD-IQ (VASAMED). The unit of measurement is mmHg.

Sekundära resultatåtgärder

1. Change in Lower Extremity Edema From Baseline to 4 Weeks [Baseline and 4 weeks]

Edema will be measured by traditional circumference change of ankle. The unit of measurement is cm.

2. Change in Plantar Sensation From Baseline to 4-week [Baseline to 4 weeks]

The change in plantar sensation after 4-weeks use of AVEX Footbeat will be assessed using vibratory perception threshold (VPT) test. The unit of this measurement is volt.

3. Change in Stride Velocity From Baseline to 4-week [Baseline to 4 weeks]

The change in stride velocity was quantified by gait speed measured using a validated wearable sensor (LEGSys, Biosensics, LLC). The unit of measurement is meter per second (m/s)
