| Abstract: | 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. [ABSTRACT FROM AUTHOR] |
