Summary

In clinical practice, it is sometimes difficult to establish whether a patient's tremor is due to Parkinson's disease or essential tremor. The distinction is crucial as the health implications differ significantly between the two conditions. Therefore, the present study aims to develop a diagnostic method based on machine learning techniques to help differentiate whether a patient's tremor is due to one condition or the other. To achieve this, 110 patients with tremor, correctly diagnosed with either Parkinson's disease or essential tremor, will participate. They will undergo two diagnostic tests (tapping test and Archimedean spiral) to capture data that can be processed using machine learning techniques.

Conditions

• Tremor
• Essential Tremor
• Parkinson Disease

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Tapping Test	For the administration of the tapping test, a computer application installed on a Tablet will be used. The test will be administered up to 3 times, with a 15-minute interval between each administration. Each tapping test trial will last 15 seconds. At the beginning of the session, the patient will perform 2 practice attempts.
DIAGNOSTIC_TEST	Archimedes Spiral	For the administration of the Archimedean spiral, a computer application installed on a Tablet will be used. The Tablet screen will display a drawing of the spiral, serving as a reference for the participant. The test will be administered up to 3 times, with a 15-minute interval between each administration. At the beginning of the session, the patient will perform 2 practice attempts.
