ABSTRACT
Objective To survey the prevalence and distribution of dyskinesia and motor fluctuations, and to investigate the factors related to the dyskinesia and motor fluctuations. Methods The detailed information were recorded, patients were rated by Unified Parkinson's disease rating scald (UPDRS) and Hoehn-Yahn stage. The occurrence of dyskinesia and motor fluctuations were recorded according to UPDRS Ⅳ. Results One hundred and twenty-two patients receiving levodopa treatment for at lease 6 months were involved. Fifteen (12.3%) were experiencing dyskinesia and 41(33.6%) motor fluctuations. The age of onset(OR=0.907,P<0.01) and daily levodopa dose (95% CI 1.000-1.004, OR=1.002, P<0.05) were independent factors with dyskinesia; while the age of onset (OR=0.922, P<0.05), levodopa treatment duration (OR=1.234, P<0.05), daily levodopa dose (95% CI 1.002-1.008, OR=1.005, P<0.01) and Hoehn-Yahn stage (OR=1.869, P<0.05) were independent factors of motor fluctuations. Conclusions The rate of motor complications was lower than the results surveyed in European countries. The likelihood of occurrence of dyskinesia and motor fluctuations is increased in those on high daily levedopa dose. The concomitant use of other medication to reduce levedopa dose might delay the motor complications.
