The psoas muscle is the largest muscle in the lower lumbar spine and is innervated by the ipsilateral lumbar spinal nerve roots (L2-L4). Here, we present a 44-year-old female with left hip pain in the posterolateral aspect of the left hip radiating to the ipsilateral hamstring, and psoas atrophy (based on imaging). She is now reported to have over 50% improvement in pain scores after underdoing temporary peripheral nerve stimulation of the psoas muscle as well as significant improvement in muscle atrophy based on an electromyography (EMG) study. This case study is the first to report documented improvement in muscle atrophy based on EMG after peripheral nerve stimulation of the targeted area.
腰大肌是腰椎下部最大的肌肉，由同侧的腰椎脊神经根（L2-L4）支配。在这里，我们介绍一位 44 岁的女性，她的左侧臀部后外侧有疼痛，放射到同侧的腘绳肌和腰大肌萎缩（基于影像学）。据报道，她在接受腰大肌周围神经刺激后，疼痛评分降低了超过 50%，并且根据肌电图（EMG）研究，肌肉萎缩也有显著改善。本病例研究是首例报告的基于目标区域周围神经刺激的 EMG 后肌肉萎缩改善的病例。
