Team Vision for Problem Definition Phase

During this project phase, the team focused on developing a thorough understanding of Essential Tremor, the work that was done by P17044, the efficacy of the existing prototypes, and understanding how our project relates to the Data Acquisition and Test Arm teams' projects.

Project Summary

A tremor mitigation device is a wearable assistive medical device that helps to control the patient's involuntary rhythmic muscle movement. Specifically, the device should diminish the intensity of the tremors and augment the patient's ability to perform daily tasks. Currently, prototypes include a proof of concept device with a testing platform for the integrated system. The prototype in place lacks some features and functionality that limit the device's readiness for implementation.

The efficacy of the device should be improved, specifically determining and refining the sensitivity of the system and addressing a wider range of movements.
