Mild Compression Sock for Control of Lower Extremity Edema in Individuals With Diabetes
Mild Compression Sock for Control of Lower Extremity Edema in Individuals With Diabetes
The purpose of this study is to determine whether a specially designed sock for people with
 diabetes and swelling in the legs can reduce the swelling, improve blood flow to the legs,
 and improve physical activity patterns of those individuals by providing mild compression to
 their legs.
Peripheral arterial disease (PAD) is commonly associated with diabetes. Clinicians are often
 reluctant to apply compressive stockings to patients with diabetes and swollen legs due to
 fear of exacerbating the symptoms of PAD. The study sock is a newly formulated sock that
 offers mild compression (18-25mmHg). The sock is made especially for the diabetic patient who
 suffers from concomitant lower extremity edema.

 Eighty patients with diabetes and lower extremity edema will be recruited. Upon ensuring
 enrollment criteria are met, baseline edema (as measured by circumference of foot, ankle and
 calf), ankle brachial index (ABI), skin perfusion pressure, and cutaneous fluid level (as
 measured by MoistureMeter) will be assessed. Subjects will then be provided four pairs of
 socks. Subjects will be randomized in a 1:1 distribution to receive either the mild
 compression diabetic socks or a standard diabetic sock. They will return for four weekly
 follow up visits.

 Additionally a sub-set of 30 subjects will be monitored for changes in physical activity pre
 and post sock usage. Physical activity monitors will be used to assess daily physical
 activity for 48hrs prior to receiving the socks and after wearing the socks for four weeks an
 additional 48hrs will be monitored.
Inclusion Criteria:

 -  Male or female with lower extremity edema aged 18 or older with the ability and
 willingness to provide Informed consent

 -  Patient's ankle-brachial systolic pressure index > 0.6 and toe-brachial index > 0.3

 -  Patient is willing to participate in all procedures and follow up evaluations
 necessary to complete the study.

 -  Patient has diabetes type 1 or type 2 confirmed by patient's primary care physician.

 Exclusion Criteria:

 -  Patients with active wound infection, or untreated osteomyelitis, gangrene

 -  Patients with dementia, or impaired cognitive function that would prohibit study
 compliance

 -  Patients with wide spread malignancy or systemically immuno-compromising disease

 -  Patients who are unable or unwilling to participate in all procedures and follow up
 evaluations

 -  Patient with deep and/or large ulcers that require copious bandaging and may affect
 efficacy of socks. Patients with superficial ulcers that only require a light dressing
 are not excluded. The ulcer, if present, must be superficial and cannot exhibit any
 clinical signs of infection

 -  Patients with restless leg syndrome, Parkinson's disease, or other disease that will
 cause involuntary movement during microvascular assessment

 -  Patients with severe edema or calf circumference greater than 24" or 46cm

 -  Patients with severe lymphedema

 -  Patients with edema that in the opinion of the investigator requires higher
 compression than the 18-25mmHg provided by the compression socks

 -  Patients who are currently wearing compression hose. (Patients who have been
 prescribed compression hose but have not worn compression stockings for the past 6
 months can be included in the study)

 -  Patients unable to walk one hundred feet.
