Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
227

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients with Parkinson Disease (PD)
  • Patients who have chronic pain (for at least 3months) moderate to severe (intensity ≥ 4/10 on visual analogue scale from 0 to 10) specific or unspecific to PD
  • Patients who have one type of pain or different type of pain: in this case, patients should suffered from one predominant pain and be able to identify it
  • Patients who have stable analgesic medication during the study
  • Patients who understand and speak fluently French
  • Patients with health insurance
  • Patients who signed the written informed consent form

Exclusion Criteria:

  • Patients with severe depression according to Diagnostic and Statistical Manual (DSM) V criteria
  • Analgesic medication modified recently (less than 1month)
  • Patients with psycho-actives substances or alcohol abused
  • Patients with cognitive impairment (MoCA score < 25)

How is the study designed?

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary Parkinsonian Pain Questionnaire (3PDQ questionnaire)
Time Frame: 4 months

Develop and validate a French self-questionnaire to diagnose parkinsonian primary pain, this symptom questionnaire will be called 3PDQ for Primary Parkinsonian Pain Questionnaire. This questionnaire present 5 items: Location of the most embarrassing pain, Characteristics of pain, if the pain is associated in the same area with one or more of the symptoms, by what is the pain caused or increased, what criteria does the pain correspond to.

It is sufficient for each item to check the corresponding boxes
