the Prevalence of "Wearing-off" in Patients With Parkinson's Disease in Shanghai
- Conditions
- Parkinson DiseaseWearing Off Effect
- Interventions
- Diagnostic Test: Wearing-off 9 questionnaire
- Registration Number
- NCT03792204
- Brief Summary
The study would be designed as a multi-center cross-sectional investigation on the prevalence of Wearing-off in Parkinson's patients in Shanghai as well as related influencing factors.
- Detailed Description
PD patients would be randomly recruited into this investigation from around thirty hospital covering the 16 districts of Shanghai. The wearing off would be defined by two methods: the doctors' judgement or the WOQ-9 questionnaire which was a patient-determining tool. The investigation also includes the medicine, the severity of PD symptoms, the demographic factors. The study would be designed with the purpose of clarifying the prevalence of the "wearing-off" and its related influencing factors.

Group Intervention Description PD patients with wearing-off effect Wearing-off 9 questionnaire people who have been clinically diagnosed with Parkinson's disease (PD) and have received anti PD therapy would be recruited into the study. The anti -PD treatment would not be changed in the population of the participants. We would use the tool of 'Wearing-off 9 questionnaire' to determine the prevalence of Wearing-off phenomenon in Parkinson's patients in Shanghai
- Primary Outcome Measures
Name Time Method the prevalence of wearing off effect in Parkinson's patients that received stable anti Parkinsonian therapy in Shanghai of China 1 year every participant receives a clinical assessment of the wearing-off symptoms by a physician and completes a self rating scale of the wearing-off 9 questionnaire (WOQ-9) to obtain a prevalence of wearing-off positive individuals( wearing-off would be diagnosed by physicians during the clinical assessments)
- Secondary Outcome Measures
Name Time Method the sensitivity and the specificity of the wearing-off 9 questionnaire in the diagnosis of wearing-off effect in Parkinson's disease. 1 year The physician assessment served as the standard for comparison with the WOQ-9 questionnaire. Sensitivity was defined as the probability that a PD patient, classified as having wearing-off (WO) according to physician assessment, would be classified as having the WO using the WOQ-9 questionnaire. The specificity was defined as the probability that a PD patient without the WO by physician assessments would be classified as being without the WO using the WOQ-9 questionnaire
the risk factors of wearing-off in Parkinson disease 1 year assess patients clinical characteristics and medical treatments, including the onset age, disease duration and daily levodopa dosage in the subsets of Parkinson patients with wearing-off diagnosed by physician assessment.
