Peripheral nerve injury (PNI) can lead to sensory and/or motor impairment. As a treatment photobiomodulation (PBM) has demonstrated positive effects in terms of the maintenance of muscle activation and trophism. Wistar rats were divided into five groups: control, injury, injury + PBMn (irradiation over injured nerve), injury + PBMm (irradiation over affected muscle) and injury + PBMnm (irradiation over nerve and muscle). The left sciatic nerve was submitted to a crushing injury. Treatment was administered with low‐level laser (780 nm, 0.04 cm2, 1 W cm−2, 3.2 J) over the injured nerve and/or the tibialis anterior muscle. The effects of PBM were favorable on muscle morphology and gene expression of calcineurin, myogenin and acetylcholine receptors. PBM led to an acceleration on muscle repair process, and effects were more evident in 2 weeks after PNI. Thus, PBM is indicated for the area over both the injured nerve and the affected muscle.

低强度激光光生物调节对Wistar大鼠周围神经损伤后肌肉修复的影响
周围神经损伤 (PNI) 可导致感觉和/或运动障碍。作为一种治疗，光生物调节 (PBM) 在维持肌肉激活和营养方面显示出积极作用。Wistar大鼠分为五组：对照、损伤、损伤+PBMn（损伤神经照射）、损伤+PBMm（受影响肌肉照射）和损伤+PBMnm（神经和肌肉照射）。左侧坐骨神经受到挤压伤。用低强度激光 (780 nm, 0.04 cm2, 1 W cm−2, 3.2 J) 对受伤的神经和/或胫骨前肌进行治疗。PBM 对肌肉形态和钙调神经磷酸酶、肌细胞生成素和乙酰胆碱受体的基因表达有好处。PBM 导致肌肉修复过程加速，PNI 后 2 周效果更明显。因此，PBM 适用于受伤神经和受影响肌肉上方的区域。
