title: Camptocormia in Chinese patients with Parkinson's disease.
abstract: To investigate the frequency and clinical characteristics of camptocormia in Chinese PD patients, we included 705 patients with PD and studied the clinical features and prevalence of camptocormia. Forty-six (6.5%) patients presented with camptocormia at the time of evaluation. The mean disease duration of PD patients with camptocormia was significantly longer than that without camptocormia (P < 0.01). After adjusted for age and disease duration, compared with patients without camptocormia, PD patients with camptocormia presented with higher score of UPDRS part III (P < 0.01), higher H&Y stage (P < 0.01), higher score of Non-Motor Symptoms Scale (P < 0.01) and lower score of Mini-Mental Status Examination (P < 0.01). Binary logistic regression models indicated that camptocormia is associated with higher H&Y stage and UPDRS part III score. Camptocormia is not rare (6.5%) with the disease progression of PD in Chinese PD population and is associated with more advanced PD.
