Studying Tremors with Electronic Sensoring
Body
The purpose of this study is to understand the neurophysiological mechanisms of peripheral electrical stimulation (PES) in modulating supraspinal tremorogenic input to motoneurons.
For this purpose, the investigators will use smart electronic testing equipment such as transcutaneous PES, high-density electromyography (HD-EMG), transcranial magnetic stimulation (TMS), electroencephalography (EEG), magnetic resonance imaging (MRI), and neuromusculoskeletal modelling.
This study will be carried out in both healthy participants and patients with essential tremor (ET) and Parkinson's disease (PD).
Healthy participants without motor disorders and medications influencing brain functions will be scanned with MRI and undergo PES and/or single pulse TMS during several visits, each with different stimulation patterns, while HD-EMG is recorded.
Participants with Parkinson's Disease or essential tremor will be scanned with MRI and undergo PES and/or single pulse TMS during several visits, each with different stimulation patterns, while HD-EMG and EEG are recorded.
The purpose of this study is to understand how motor activation can be reduced.
For this purpose, it will be examined how some muscles of the arm respond to electric and magnetic stimulation. The effects of the electric and/or magnetic stimulation will be recorded non-invasively with HD-EMG equipment.
