Summary

Neuropathic ulcers are common sequelae of leprosy. The objectives of this study are to analyze the clinic-epidemiological characteristics of patients attended at one specialized dressing service from a leprosy-endemic region of the Brazilian Amazon and to evaluate the effect of Low Level Laser Therapy on wound healing of these patients.

Conditions

• Leprosy

Interventions

Type	Name	Description
PROCEDURE	Routine treatment	Subjects from the Control Group received routine treatment, including daily simple dressings with sterile gauze after wound cleaning with a 0.9% physiologic solution, use of 1% hydrophilic silver sulfadiazine cream (Prati Donaduzzi Laboratory, Toledo, Brazil) and orientation about the use of adapted footwear, self-care and the prevention of disabilities. Surgical debridement was done whenever indicated by nursing or orthopedic services from UREMC.
RADIATION	Low level laser therapy (LLLT)	The LLLT equipment was an indium-gallium-aluminnium-phosphide (InGaAlP) semiconductor laser with a maximum output power of 40 mW, continuous radiation emission of visible red light with 660 nm wavelength (+/- 10 nm) and a spot area of 0.04 cm². The energy density used was 4 J per point in the wound edges and 2 J/cm² in the wound bed with a power density of 1 W/cm2. Wound beds were irradiated using a scanning technique with no direct contact.
