Article Abstract

Background: Electrical stimulation (E-Stim) may offer a unique adjunctive treatment to heal complicated diabetic foot ulcers (DFU). Our primary goal is to examine the effectiveness of daily home-based E-Stim therapy to speed-up wound healing.

Methods: Patients with chronic DFUs and mild to severe peripheral arterial disease (PAD) were recruited and randomized to either control (CG) or intervention (IG) groups. The IG received 1-hour home-based E-Stim therapy on daily basis for 4 weeks (4W). E-Stim was delivered through electrical pads placed above the ankle joint using a bio-electric stimulation technology (BEST) platform (Tennant Biomodulator PRO). The CG was provided with an identical but non-functional device for the same period. The primary outcome included wound area reduction at 4W from baseline (BL).

Results: Thirty-eight patients were recruited and 5 were removed due to non-compliance or infection, leaving 33 participants (IG, = 16; CG, =17). At 4W, the IG showed a significant wound area reduction of 22% (BL: 7.4 ± 8.5 cm vs 4W: 5.8 ± 8.0 cm, = 0.002). Average of wound area was unchanged in the CG ( = 0.982). The self-report adherence to daily home-therapy was 93.9%.

Conclusions: Daily home-based E-Stim provides early results on the feasibility, acceptability, and effectiveness of E-Stim as an adjunctive therapy to speed up wound healings in patients with chronic DFU and mild to severe PAD.

Introduction: Electrical stimulation (E-stim) can reduce the impact of complications, like spasticity, bladder dysfunction in people with spinal cord injuries (SCIs), enhancing quality of life and health outcomes. With SCI prevalence high in regional Australia and a shift towards home-based community integrated care, the perspectives of people with SCI and healthcare professionals on current and future use of E-stim home-devices are needed.

Methods: A mixed-methods concurrent triangulation approach was used.

Transcranial direct current stimulation (tDCS) is a potential treatment strategy across some psychiatric conditions. However, there is high heterogeneity in tDCS efficacy as a stand-alone treatment. To increase its therapeutic potential, researchers have begun to explore the efficacy of combining tDCS with psychological and pharmacological interventions.
