(p < 0.02). Granulation tissue, not present prior to treatment, was present in all PEMFT ulcers by
day 15, whereas seven sham group ulcers showed new granulation tissue. The other RCT (Stiller
et al., 1992) investigated 27 patients with recalcitrant VU. Patients were treated for 8 weeks at home
for 3h per day with a wearable portable EMF device that delivered a 22 Gauss bidirectional pulse of
3.5 ms at a 25% duty cycle. All received compression bandaging and daily 3h leg elevation. At week
8, the PEMFT group (N = 17) had a 47.7% decrease in wound surface area vs. a 42.3% increase for
sham (p ...
