Using a tap test and spiral drawing to diagnose tremors
Part of Brain & nervous system clinical trials.
This study uses a simple tapping test and drawing a spiral (like on paper) to tell the difference between tremors caused by Parkinson's disease and essential tremor. It may help you get a more accurate diagnosis without extra procedures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have a confirmed diagnosis of either Parkinson's disease with tremor or essential tremor.
- You need to be followed by the Movement Disorders clinic at Hospital Sant Camil in Barcelona.
- You cannot be taking antipsychotic or antidepressant medications.
- You cannot be taking dopamine agonists or primidone (a common tremor medication).
- You must not have severe tremor that prevents drawing a continuous line, or certain other conditions like alcoholism, neuropathy, dystonia, or a past stroke.

This study uses a device on your body to detect internal tremors (tiny vibrations you may feel inside) in Parkinson's disease. It helps researchers understand these tremors better and compare them to people without Parkinson's.
This study tests a special glove designed to reduce hand shaking in people with essential tremor. It may help you feel steadier with daily tasks like drinking.
This trial tests whether a non-invasive brain stimulation method called Temporal Interference can help reduce tremors in people with essential tremor. It may offer a new way to calm hand shaking without surgery or medication.
This study uses a simple eye movement test to see if it can help tell the difference between Parkinson's disease, Essential tremor, and healthy people. The goal is to find a better way to diagnose and track these conditions.
This study looks for biological markers to better understand different types of essential tremor and how the condition changes over time. It may help identify who has which subtype and predict disease progression.
This study uses a small skin sample to look for a protein linked to Parkinson's disease. It aims to help people with essential tremor understand their risk of developing Parkinson's, which could guide future care.
