Detailed Description

The aim of this study is to develop and validate a French self-questionnaire to diagnose parkinsonian primary : the "Primary Parkinsonian Pain Diagnostic Questionnaire" (3PDQ). It will allow clinicians to distinguish this pain from the other pain of the parkinsonian patient (whether or not related to Parkinson's disease).

The development and validation of the 3PDQ self-questionnaire will take place in 3 sequential steps:

  1. design of the self-questionnaire
  2. appearance validity study
  3. validation of the self-questionnaire

Participants :

Appearance validity study: 40 painful parkinsonian patients Validation study: 200 painful parkinsonian patients (10 patients per item)

Duration of the study :

Duration of the inclusion period:

  • Appearance validity study : 6 months
  • Validity study : 20 months

Duration of participation for each patient:

  • Appearance validity study : about 30 min
  • Validity study : 3 days maximum Total duration of the study: (with results analysis): 3 years

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 3PDQ self-questionnaire validation
200 patients will be included for this step in 10 French Parkinson expert centers.
Diagnostic test: Self-questionnaire 3PDQ

Visit 1 : - The patient will have to complete the 3PDQ self-questionnaire. - The investigator will conduct an interrogation and a neurological examination in order to ask or not the diagnosis of parkinsonian primary pain, without knowing the result of the 3PDQ.

Visit 2 : - The patient will have to complete the 3PDQ self-questionnaire.

- An investigator, obligatorily different from the investigator of the visit 1, will conduct to the same interrogation and the same neurological examination in order to ask or not the diagnosis of parkinsonian primary pain, without knowing the result of the 3PDQ.

Visits 1 and 2 can be made on the same day. In this case the patient will fill the 3PDQ self questionnaire only once.
