Axial myopathy is a rare neuromuscular disorder characterised by selective involvement of the paraspinal muscles, and presenting either as a bent spine and/or dropped head syndrome. The axial muscles can be involved in various conditions, including neuromuscular disease, movement disorders, spinal disease and metabolic disorders. There have been recent descriptions of disorders with selective axial muscle involvement, but overall axial myopathy remains under-recognised. Here, we review disorders of axial muscle function, provide guidance on interpreting axial muscles imaging and suggest a diagnostic algorithm to evaluate patients with axial muscles weakness.

 轴向肌无力


轴性肌病是一种罕见的神经肌肉疾病，其特征是选择性累及椎旁肌肉，并表现为脊柱弯曲和/或低头综合征。轴肌可能涉及多种疾病，包括神经肌肉疾病、运动障碍、脊柱疾病和代谢紊乱。最近有关于选择性轴肌受累疾病的描述，但总体轴肌病仍然未被充分认识。在这里，我们回顾轴向肌肉功能障碍，提供解释轴向肌肉成像的指导，并提出评估轴向肌肉无力患者的诊断算法。
