Correlation of Motor Metrics and Neurological Data

Study Overview
=================
Brief Summary
-----------------
This is a pilot study to collect data with the Ceraxis product and standard movement disorders tests in order to prove and codify potential correlations.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Collection of data with Ceraxis product (stylus product with a built-in Inertial Measurement Unit (IMU) which includes a 3-axis accelerometer, gyroscope, and magnetometer, as well as a force sensing tip) | Patients will be guided through a set of actions while the sensors record movement data on their upper and lower extremity motor symptoms. This data will be correlated with the secondary outcome measures post hoc. | Day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| UPDRS-I, UPDRS-II, and UPDRS-III assessment for patients with Parkinson's disease |  | Day 1 | 
| TETRAS tremor rating scale for patients with Essential Tremor |  | Day 1 | 
| Upper extremities motor strength, assessed by neurological examination |  | Day 1 | 
| Coordination test for the upper extremities to evaluate dysdiadochokinesia |  | Day 1 | 
| Archimedes Spiral task |  | Day 1 | 
| Freezing of Gait questionnaire |  | Day 1 | 
| Usage Survey | Custom survey given to patients to collect their impressions of the Ceraxis product | Day 1 |
