To evaluate the effectiveness of a transcutaneous electric nerve stimulation (TENS) device typically used for pain suppression (analgesia) during pressure injury (PI) healing, peripheral vascularization, and secondary pain in older adults with chronic PIs and cognitive impairment.
This pilot clinical trial followed patients from 6 nursing homes.
Twenty-two patients with PIs in the distal third of their lower limbs (7 men, 15 women) were included in this study. The control group completed standard wound care (SWC), whereas the experimental group received SWC and TENS. A total of 20 sessions were conducted for each group over 2 months, 3 times a week.
PI area, PI healing rate, blood flow, skin temperature, oxygen saturation, and level of pain at baseline and posttreatment.
Significant improvements were achieved in PI area (mean difference, 0.92; 95% confidence interval [CI], 0.15–1.67; P =.024), healing rate (3; 95% CI, 1–4.99; P =.009), skin temperature (1.82; 95% CI, 0.35–3.28; P =.021), and pain (1.44; 95% CI, 0.49–2.39; P =.008) in the experimental group, whereas none of the variables revealed a significant change in the control group.
The effect of local and spinal TENS combined with the SWC for PI produced a significant improvement in size, healing, skin temperature, and pain levels.
