Electrical Stimulation to Enhance Wound Healing.

Area of Science:

• Biomedical Engineering
• Wound Healing Research
• Regenerative Medicine

Background:

• Chronic wounds present a significant clinical challenge due to impaired healing mechanisms.
• Electrical stimulation (ES) is explored as a therapeutic intervention to overcome these healing deficits.
• Understanding ES's cellular effects is crucial for optimizing wound treatment.

Purpose of the Study:

• To review the cellular mechanisms by which electrical stimulation influences wound healing.
• To evaluate the efficacy of ES in treating both acute and chronic wounds.
• To synthesize evidence from in vitro, in vivo, and clinical studies on ES for wound management.

Main Methods:

• Comprehensive literature search across major scientific databases (Cochrane, Medline, Web of Science, Google Scholar, PubMed).
• Inclusion of 30 full-text articles with no publication date restrictions.
• Analysis of in vitro, in vivo, and randomized controlled trial (RCT) data on ES effects.

Main Results:

• In vitro and in vivo studies show ES enhances epithelialization, fibroblast migration, and vascularity.
• ES exhibits bactericidal effects against pathogens in vitro.
• Twelve RCTs confirm pulsed current ES significantly reduces chronic wound size and accelerates healing compared to controls.

Conclusions:

• Electrical stimulation therapy is a viable option for improving chronic wound healing outcomes.
• ES may reduce the economic burden associated with complex wound care.
• Further systematic RCTs are needed to standardize ES parameters for diverse wound types and patient populations.
