Propriospinal myoclonus (PSM) is a rare segmental movement disorder characterized by repetitive irregular myoclonic jerks of the trunk and/or axial limbs at the resting state. It is imperative to make a correct diagnosis as other movement disorders can be mistaken for or mask PSM. Therefore, a battery of neuroimaging and neurophysiological testing must be undertaken. In our case report, we discuss a patient who was diagnosed with PSM concurrently with cervical degenerative stenosis and then had a successful outcome via surgical decompression and arthrodesis of the cervical spine. We documented the patient's postoperative course and achievement of complete remission, sustained at a 41-month follow-up. We then grouped our case together with five other PSM cases in the literature to offer readers a broader context of the role of surgical spinal intervention in ameliorating PSM.
脊髓性肌阵挛（PSM）是一种罕见的节段性运动障碍，其特征是在静息状态下躯干和/或轴性肢体出现重复性不规则肌阵挛性抽搐。由于其他运动障碍可能被误诊为PSM或掩盖PSM，因此做出正确诊断至关重要。因此，必须进行一系列神经影像学和神经生理学检查。在我们的病例报告中，我们讨论了一名同时被诊断为PSM和颈椎退行性狭窄的患者，该患者通过颈椎手术减压和融合术获得了成功的治疗结果。我们记录了患者的术后病程以及完全缓解的情况，并在41个月的随访中得以维持。然后，我们将我们的病例与文献中的其他五个PSM病例进行了汇总，以便为读者提供关于脊柱手术干预在改善PSM方面作用的更广泛背景。
