Prevalence and Clinical Characteristics of Mirror Movements in a Chinese Cohort of Parkinson's Disease Patients.

ABSTRACT:

Background and objectives

Mirror movements (MMs) are involuntary movements produced by the contralateral homologous muscles during voluntary activity. MMs have been observed in age-related neurological movement disorders, including Parkinson's disease (PD), but they are not widely recognized. This study described the frequency and clinical features of MMs in PD patients from a tertiary care center in Eastern China.

Methods

A clinical scale was used to compare the amplitude, distribution, and proportion of mirroring between the suspended and supported positions.
