It will be hypothesized that~Age may significantly affect burn wound healing's response to low level laser therapy.~TBSA may significantly affect burn wound healing's response to low level laser therapy.~Depth of wound may significantly affect burn wound healing's response to low level laser therapy.~Wound healing stage may significantly affect burn wound healing's response to low level laser therapy. There will be only one intervention group. The duration of the study will be 6 weeks divided to 18 sessions (three sessions per week). Sixty patients (male and female) will be recruited from the burn units.~Low level laser therapy will be performed for 30 min 3 times per week for 8 weeks on the wound area.~Wound area was irradiated by a red 655 nm light, 150 mW, 2 J/cm2 at the bed of the wound.
The purpose of this study is to investigate whether patients' age, total burned surface area, wound stage and wound depth determine wound healing response to low level laser therapy in burn patients
