INTRODUCTION
An isolated asymmetric arm swing can represent the beginning of Parkinson's disease (PD) but also be related to physiological or non-specific musculoskeletal pathology.
PATIENTS AND METHODS
In this brief clinical observation including 15 patients with asymmetric arm swing, we provide a new clinical clue to evaluate the risk of subjacent parkinsonism.
RESULTS
Among non-parkinsonian subjects, the immobilization of the contralateral arm, by asking the patient to put his hand on the contralateral shoulder, induced a clear increase in the amplitude of the arm swing, whereas in PD patients, the arm swing amplitude did not significantly vary when the contralateral upper limb was immobilized.
CONCLUSIONS
This novel clinical sign may be helpful when approaching patients with gait abnormalities and specifically reduced arm swing.
引言
孤立的不对称摆臂可能是帕金森病（PD）的起始表现，但也可能与生理或非特异性肌肉骨骼病变有关。
患者与方法
在这项纳入15例不对称摆臂患者的简短临床观察中，我们提供了一条评估潜在帕金森综合征风险的新临床线索。
结果
在非帕金森病受试者中，让患者将手放在对侧肩部以固定对侧手臂，会导致摆臂幅度明显增加，而在帕金森病患者中，固定对侧上肢时摆臂幅度无显著变化。
结论
这一新颖的临床体征在诊治步态异常尤其是摆臂减少的患者时可能会有所帮助。
