Conditions
Outcome Measures
Primary Outcomes (6)
Thermal induced heat pain
Thermal heat detection and pain thresholds will be measured following the standardized "Quantitative Sensory Testing" protocol
Immediately after assessment of ongoing pain (15 minutes)
Mechanical induced pain
Mechanical pain thresholds and suprathresholds will be measured by use of a handhold pressor algometer (Somedic, Hörby, Sweden) with a 1-cm2 probe placed on test muscle (gluteus medius muscle, tibialis anterior muscle, and infraspinatus muscle in a randomized order)
Immediately after assessment of thermal induced heat pain (15 minutes)
Chemical induced pain
Chemical pain will be induced by an injection of hypertonic saline (HS, 5,8% in 1 ml)
Immediately after assessment of mechanical pain (15 minutes)
Ongoing pain (Clinical pain in daily life)
Intensity and discomfort of ongoing pain in gluteus medius muscle, tibialis anterior muscle, and infraspinatus muscle will be assessed by use of 11- point Numeric Rating Scale (NRS)
After assessment of motor response latencies measure (15 minutes)
Ongoing pain (Sensory and affective verbal descriptions of pain and patient drawings)
Sensory and affective verbal descriptions of pain and patient drawings of pain size and distribution will be measured by use of the short-form McGill Pain Questionnaire (SF-MPQ).
After assessment of motor response latencies measures (15 minutes)
Ongoing pain (Pain in PD)
Pain in PD will be assessed by King´s Parkinson´s disease pain scale (KPPS)
After assessment of motor response latencies measures (15 minutes)
Secondary Outcomes (1)
Motor response latencies measure
Prior to assessment of ongoing pain (3 minutes)

Eligibility Criteria
You may qualify if:
- Group healthy volunteers: healthy subjects with no PD diagnosis
- Group PD patients levodopa: Include PD patients treated with levodopa
You may not qualify if:
- Known other neurological or medical disorders (e.g., stroke, neuropathy, diabetes) or other disorders with expected influence on experimental pain
- Known dementia (a score \<24 on the MoCA)
- Known untreated depression (a score ≥15 on the Beck Depression Inventory)
- Unable to cooperate
- Treated with painkillers except paracetamol and NSAID (except if pain and treatment is ad-equately stable as evaluated by a doctor)
