Interventions

OTHER

Photon Therapy Combined with Ultrasonic Debridement Group

Participants in this arm received the combined intervention of ultrasonic debridement followed by photon therapy in addition to standard moist wound care and systemic management. Ultrasonic debridement was performed using a handheld device held at a 45-degree angle approximately 0.5 cm from the wound surface to selectively remove necrotic tissue. Subsequently, photon therapy was administered with the light source positioned 10 cm from the wound for 15 minutes per session, using blue light (for infected wounds) followed by red light as indicated. This combined physical therapy regimen aimed to enhance wound bed preparation, reduce bacterial load, promote tissue repair, and accelerate healing in elderly patients with stage 3 or 4 pressure injuries.

OTHER

Standard Wound Care Group

Participants in this arm received standard moist wound care guided by the TIME principle (Tissue management, Infection/inflammation control, Moisture balance, and Edge advancement) and systemic interventions. Wounds were cleansed with 0.9% normal saline, and appropriate dressings were selected based on wound stage and exudate level. Dressing change frequency was determined according to clinical need. Systemic factors affecting wound healing were addressed, and comprehensive health education was provided, including guidance on repositioning, nutrition, and home care. This arm served as the control to evaluate the added benefit of the combined physical therapy intervention.
