Movement Disorders Clinical Trials

The goal of this clinical trial is to learn to what extent daily stimulation of the brain with transcranial pulsed electromagnetic fields (T-PEMF) works to treat persons with Parkinson's Disease. The main questions it aims to answer are: * How does 6 months of daily treatment (30 minutes/day) with T-PEMF affects neuro-mechanical and molecular biological factors compared with placebo treatment in persons with Parkinson's disease? * How does 12 months of daily treatment (30 minutes/day) with T-PEMF affects neuro-mechanical and molecular biological factors in persons with Parkinson's disease an does 12 months of T-PEMF alters the need for medication intake? The neuro-mechanical outcomes are compared with the natural progression of the disease as well as with a healthy reference group. Furthermore, it will be examined whether 12 months of T-PEMF treatment alters the need for medication intake. Participants in the intervention group will: * receive one 30 min treatment session daily for 12 months * receive either T-PEMF or sham treatment for the first 6 months * receive active T-PEMF treatment the last 6 months * visit for tests before treatment initiation, after 6 months of treatment and after 12 months of treatment.
