Abstract
Objectives:
This double-blind crossover-controlled trial aimed to verify the effect of electrical
stimulation therapy on pressure injuries with undermining.
Methods
: In this trial, we compared the healing rates between a sham period and a treatment
period using monophasic pulsed microcurrent therapy. The participants were randomly
assigned to the sham or treatment group and received stimulation for 2 weeks. All the
participants, physical therapists, and researchers were blinded to the allocation. For
the main analysis, data on the effect of the intervention on changes in weekly healing
and contraction rates of the wound areas, including undermining, were analyzed based on
a two-period crossover study design. The intervention effect was estimated by examining
the mean treatment difference for each period using Wilcoxon’s signed-rank test.
Results
: The reduction of the entire wound area, including the undermining area, resulted in
significantly higher healing and contraction rates in the treatment group (overall wound
area reduction rate: contraction rate, P=0.008; period healing rate, P=0.002).
Conclusions
: Electrical stimulation therapy for pressure injuries, using conditions based on the
findings of an in vivo culture study, was effective in reducing the wound area.
