Laser Photobiomodulation for Hard-to-heal Ulcers in Frail Older Adults

Summary

The aim of this quasi-experimental prospective study is to evaluate the effectiveness of photobiomodulation treatment on hard-to-heal ulcers of various diagnosed aetiologies in frail older adults, admitted to municipal home healthcare. The study also include evaluation of cost-effectiveness, and healthcare providers experiences of treating frail older adults hard-to-heal ulcers with photobiomodulation treatment in home healthcare.

Conditions

• Hard-to-heal Wounds
• Venous Leg Ulcer (VLU)
• Arterial Leg Ulcer
• Pressure Ulcer (PU)

Interventions

PROCEDURE

Photobiomodulation

Photobiomodulation treatment in addition to standard-of-care ulcer dressings for hard-to-heal ulcer according to aetiology. * 904 nm Infrared PBM applied to lymphatic area and ulcer area. * Starting at shoulder/neckline (120 s, dose 7.2 J/cm2 bilateral). * Local lymphatic area closest to the ulcer (120 s, dose 7.2 J/cm2). * Intact skin close to the ulcer (30 s per location above, below, each side of the ulcer. Dose 1.8 J/cm2, contact application). * Ulcer surface irradiated at a distance of 1 cm with projection application (120 s per position, dose 7.2 J per laser diode). * The 635 nm Red PBM treatment applied to ulcer edges and ulcer surface. * Starting at ulcer edges (30 s per position and a dose of 2.25 J/cm2) and stepwise moved 1cm covering the total ulcer edge with contact application. * The ulcer surface was irradiated at a distance of 1 cm with projection application, (120 s per position emitting 9 J from the laser diode)

PROCEDURE
