To compare the influence of laser and LED on tissue repair and neuropathic symptoms during treatment of diabetic foot. An intervention survey conducted in a health center located in Brazil, contemplating ten sessions, twice a week, with randomization in two groups. In one group, the wounds were treated with GaAlAs laser, with a wavelength of 830 nm, 30 mW, and power density 0.84 W/cm, the other group by LED 850 nm, 48 mW, and power density 1.05 W/cm. For the analysis of wound size, photographic records analyzed by the ImageJ® software were used, and the neuropathy evaluation card examined. With regard to the laser group, a reduction in wound extension of 79.43% was observed at the end of the 10th session; the patients in the LED group had a 55.84% decrease in the healing process; comparing the two therapies was observed a better healing in the participants of the laser group, with 81.17%, in relation to the LED after the end of the sessions; regarding the evaluation of the neuropathic condition, there was a significant improvement in both therapies. There was improvement of the neuropathic signs and symptoms, also improvement of the tissue repair in the two therapeutic modalities; however, the laser presented a higher rate of speed in relation to the LED.
比较激光和 LED 在治疗糖尿病足过程中对组织修复和神经病变症状的影响。在巴西的一个健康中心进行了一项干预调查，共进行十次治疗，每周两次，随机分为两组。一组伤口采用波长 830nm、30mW、功率密度 0.84W/cm 的 GaAlAs 激光治疗，另一组采用波长 850nm、48mW、功率密度 1.05W/cm 的 LED 治疗。对于伤口大小的分析，使用 ImageJ®软件分析照相记录，并检查神经病学评估卡。在激光组中，第 10 次治疗结束时观察到伤口扩展减少了 79.43%；LED 组的愈合过程减少了 55.84%；比较两种治疗方法发现，激光组的参与者在治疗结束后愈合情况更好，为 81.17%，而 LED 组为 76.03%；关于神经病变状况的评估，两种治疗方法都有明显改善。两种治疗方法都改善了神经病变的体征和症状，也改善了组织修复；然而，激光在速度方面比 LED 更快。
