West Sweden Parkinson Objective Measurement Registry Study

The following data will be collected at baseline:

Date of birth Handedness Family history of Parkinson's disease Time of first motor symptom onset Laterality of symptom onset Time of diagnosis Time of first pharmacological intervention (if applicable) First antiparkinsonian drug

The following data will be collected at every visit/update Current living conditions Current non motor complications Current medications Hoehn and Yahr staging Clinical Impression of Severity Index in Parkinson's disease (CISI-PD)

Patient self assessments: PDQ8, NMS-Questionnaire, EQ5D-5L, Patient Reported Outcome in Parkinson's Disease (PRO-PD)

Parkinson Kinetigraph (PKG) accelerometry based recording of spontaneous movement patterns over a 6x24h period. The following indices will be extracted: median bradykinesia score (BKS), median dyskinesia score (DKS), Fluctuation Dyskinesia Score (FDS), Percent daytime with Immobility (PTI%), Percent daytime with tremor (PTT%).

The primary analysis will be descriptive and include demographic composition of the population, clinical characteristics and objective measurement data. In addition to indices a standardized qualitative assessment of PKG recordings will be made to identify motor fluctuations. Correlations between clinical ratings, patient reported outcomes, disease duration, age, medication and objective measurement indices will be studied

In the prospective phase of the study the development of objective movement recordings will be studied along with the development of clinical ratings and patient reported outcomes.
