Photobiomodulation therapy (PBMT) has been used to improve the physical performance of individuals with advanced age; however, there are no studies in the literature that support the application of light-emitting diode (LED) therapy for the muscular performance of individuals with diabetes mellitus who show a decline in functionality. The aim of the study was to analyze the acute effects of PBMT on strength and functional performance in type 2 diabetic individuals. Sixty-three volunteers were recruited and randomized into five groups: control (C), sham (S), red LED (R), infrared LED (IR), and red LED + infrared LED (R + IR). On the first day, the volunteers were evaluated using the time up and go (TUG), the 6-min walk test (6MWT), and isokinetic dynamometer of the ankle. In the following 3 days, groups R, IR, R + IR, and S returned for application of PBMT bilaterally, with 180 J of energy on each leg. On the fifth day, a reassessment was performed. There was no statistical difference between groups for the variables of the isokinetic dynamometer, TUG, and 6MWT. Analysis of the size of the clinical effect for the isokinetic variables showed that there was no pattern among the effects observed. There is a moderate effect in favor of R, IR, and R + IR in relation to C for the TUG and a moderate effect of R + IR in relation to C for the 6MWT. The PBMT applied for a short period does not bring important gains for the muscular performance and functionality of diabetic individuals.
光生物调节疗法（PBMT）已被用于提高高龄个体的身体表现；然而，目前尚无文献支持将发光二极管（LED）疗法应用于糖尿病患者的肌肉表现，这些患者的功能出现下降。本研究旨在分析 PBMT 对 2 型糖尿病个体的力量和功能表现的急性影响。招募了 63 名志愿者，并将其随机分为五组：对照组（C）、假照组（S）、红光 LED 组（R）、红外线 LED 组（IR）和红光 LED + 红外线 LED 组（R + IR）。在第一天，志愿者们接受了时间起身和行走测试（TUG）、6 分钟步行测试（6MWT）和踝关节等速测力计评估。在接下来的 3 天里，R、IR、R + IR 和 S 组返回进行双侧 PBMT，每条腿的能量为 180J。在第五天进行了重新评估。在等速测力计、TUG 和 6MWT 等变量方面，各组之间没有统计学差异。对等速变量的临床效果大小进行分析表明，观察到的效果之间没有模式。与 C 相比，R、IR 和 R + IR 对 TUG 有中度影响，R + IR 对 6MWT 有中度影响。短期应用 PBMT 不会给糖尿病患者的肌肉表现和功能带来重要收益。
