About Essential Tremor
Over 10 million people in the United States suffer from Essential tremor (ET), a prevalent neurological disease that causes patients to suffer from rhythmic and unwanted motions in their upper limbs when they are voluntarily moving or positioning their upper extremities against gravity. Consequently, ET patients are unable to perform—or do so with difficulty—tasks that require use of their arms and hands (e.g. eating, drinking, typing, writing), which further affect them professionally and psychologically. According to neurologists, approximately 40% of patients do not respond to or are not candidates for current treatments for ET, such as heavy medication and Deep Brain Stimulation surgery. Therefore, these patients are forced to rely on assistive devices. There is currently no device on the market that subtly and comfortably suppresses tremor for multiple daily behaviors.
We are NoMor, a team of five biomedical engineering undergraduates seniors at Columbia University dedicated to tackle the effect of Essential tremor on the lives of million of patients. Chiara and Caroline are mostly in charge of business relations and management. With experience in finance and consulting, they create financial projections and constantly refine our business model. Walid, John and Hae Seong are in charge of building and testing the prototype. John has great data analysis skills and is in charge in quantifying tremor motions and their suppression with our device as well as the design of testing methods. Walid is our Mechanical Engineering expert and uses his 3D modeling skills to design most of our prototype models. Hae Seong brings his experience in process development and scientific thinking from his many years of scientific research. We all use our education in Biomedical Engineering to develop novel methods of tackling Essential tremor.
How does it work?
We want to ensure that our device stabilizes the hand so that patients can carry out daily activities. We also want to ensure that the device is subtle and sized appropriately to not cause any inconvenience for the user. After having performed testing last semester, we came to the conclusion that the mechanical suppression of tremor is a valid approach for designing our device. We are in our second iteration of prototyping. Our device currently consists of a long-sleeved glove that uses rigid as well as elastic components to suppress hand tremors while still allowing normal voluntary motion of the hand.
