Electric
Current Helps Diabetic Foot Ulcers
NEW
YORK (Reuters Health) - A device that delivers high-voltage electric
stimulation to the skin can help diabetic foot ulcers heal, preliminary
study findings suggest.
People with
diabetes may develop foot ulcers as a result of poor circulation
and a reduced ability to fight infection. Usually, ulcers are
treated by cleaning and dressing the wound to keep it moist and
resting the affected limb, but in some cases, damage can be severe
enough to require amputation.
According
to a report in the June issue of the Archives of Physical Medicine
and Rehabilitation, patients who used an electric stimulation
device in addition to standard treatment were more likely to heal.
The study
of 35 diabetic patients compared high-voltage, pulsed galvanic
electric stimulation every night for 8 hours with an inactive
placebo treatment that felt the same but delivered no current.
Patients also underwent weekly removal of dead tissue, topical
treatment and rest.
Over 3 months,
65% of patients who received electric stimulation healed, compared
with 35% of patients in the placebo group.
It is not
clear how electric stimulation aids in wound healing, but the
researchers suggest that it may enhance blood flow and immune
system cell function.
``It's not
a silver bullet,'' study author Dr. Lawrence A. Lavery of the
University of Texas Health Sciences Center in San Antonio, told
Reuters Health, noting that the device should be used in combination
with other measures. However, he added, ``it is more promising
than some pharmaceuticals that I've seen.''
There was
no difference in the amount of time it took for wounds to heal
among groups, the study found.
Still, ``the
results of this study are quite promising and compare favorably
with several recent reports in the medical literature on wound
healing in persons with diabetes mellitus,'' Lavery and colleagues
conclude.
They add that
larger trials should be conducted to further investigate whether
electric stimulation can help diabetic foot ulcers to heal.
