Abstract
Purpose: to evaluate the therapeutic efficacy of the Light Emitted Diode irradiation on chronic non healed wound after below knee amputation Methods:- 12 females and 18 males patients with chronic non healed ({u2265} 4 weeks) wound after below knee amputation. were divided into two groups. group (A) received the Light Emitted Diode irradiation for 24 sessions in addition to the standard medical treatment, the second experimental group (B) received the standard medical treatment for 8 weeks consisting of systematic antibiotic, irrigation with saline and wound dressing. Methods of evaluation (wound surface area: for tracing the wound perimeter using a computerized software) Results:- Result showed that both Light Emitted Diode irradiation therapy and standard medical treatment were effective in healing the chronic non healed wound .but the Light Emitted Diode was more effective than standard medical treatment alone. Conclusion:- A clear improvement in the results of wound healing was found in the group (A) which the improvement percentage was 50.63% than group (B) using the standard medical treatment alone with improvement percentage 43.96%.
