Electrostimulation: Current Status, Strength of Evidence Guidelines, and Meta-Analysis

Area of Science:

• Wound healing research
• Biomedical engineering
• Clinical practice

Background:

• Delayed skin wound healing presents significant challenges for patients and healthcare systems.
• Effective interventions to accelerate wound healing are crucial for improving patient outcomes.
• Standard wound care (SWC) is the current baseline treatment for most wounds.

Approach:

• Systematic analysis of 15 randomized controlled trials on electrostimulation (ES) as an adjunct to SWC.
• Evaluation of healing rates using percentage area reduction in 4 weeks (PAR4).
• Presentation of results in forest plots, comparing SWC + ES versus SWC alone or with placebo ES.

Key Points:

• Adding ES to SWC increases PAR4 by an average of 26.7% across all wound types.
• Unidirectional ES boosts PAR4 by 30.8% when added to SWC.
• Unidirectional ES applied to pressure ulcers increases PAR4 by 42.7%.

Conclusions:

• Electrostimulation is a proven effective adjunct therapy for accelerating wound healing.
• A gap exists between ES efficacy and its clinical application due to perceived complexity and resource needs.
• Enhanced clinician training in ES application is recommended for optimal patient care in delayed wound healing.
