Chronic nonhealed wound after below-knee amputation is a serious problem that is faced by the health care team; therefore, there is a need to find an adjuvant therapy to address this problem. The aim of the study is to evaluate the therapeutic efficacy of light-emitting diode (LED) irradiation on chronic nonhealed wound after below-knee amputation using a digitalized method of evaluation by Adobe Photoshop CS5 aided by magnetic lasso tool. Thirty patients with chronic nonhealed wound (≥4 weeks) after below-knee amputation were randomly divided into 2 equal groups, with 15 participants in each. Group A received the LED irradiation for 24 sessions (3 sessions per week) in addition to the standard medical treatment, and the second experimental group (group B) received the standard medical treatment for 8 weeks. Methods of evaluation included the wound surface area: for tracing the wound perimeter using a computerized software. Results showed that both LED irradiation therapy and standard medical treatment were effective in healing the chronic nonhealed wound, but the LED was more effective than standard medical treatment alone. A clear improvement in the results of wound healing surface area was found in group A, with an improvement percentage of 50.63%, when compared with group B, which used the standard medical treatment alone, with an improvement percentage of 43.96%.
膝下截肢术后慢性不愈合伤口是医疗团队面临的一个严重问题；因此，需要找到一种辅助治疗方法来解决这个问题。本研究的目的是使用Adobe Photoshop CS5辅助磁性套索工具的数字化评估方法，评估发光二极管（LED）照射对膝下截肢术后慢性不愈合伤口的治疗效果。30例膝下截肢术后慢性不愈合伤口（≥4周）患者被随机分为两组，每组15人。A组除接受标准药物治疗外，还接受24次LED照射（每周3次），第二实验组（B组）接受8周的标准药物治疗。评估方法包括伤口表面积：使用计算机软件追踪伤口周长。结果表明，LED照射疗法和标准药物治疗对慢性不愈合伤口的愈合均有效，但LED比单独的标准药物治疗更有效。与仅使用标准药物治疗的B组相比，A组伤口愈合表面积结果有明显改善，改善率为50.63%，B组改善率为43.96%。
