Health Care Issue: Stroke
According to the CDC, approximately 795,000 people suffer from a stroke every year in the United States. A stroke is defined as a sudden disabling attack or loss of consciousness caused by an interruption in the flow of blood to the brain, especially through thrombosis. Strokes also happen to be the leading cause of death, as well as serious disability in America, reducing mobility in over half of stroke victims over the age of 65. Many people suffer from reduced motor function, or even complete paralysis of one side of their bodies after brain cells have been destroyed after a stroke, even minor ones. A problem most people report having is loss of function in one or both arms. This is because certain areas in the brain have been damaged and brain cells and neurons responsible for motor function have been destroyed. While our device is designed with stroke victims in mind, it could also work for anyone suffering from decreased muscle/motor function.

Competitors (Advantages vs Disadvantages)
A. Advantages Of Other Neuro-robotic/Myoelectric Braces Custom made for the wearer Fitted with high tech sensors
B. Disadvantages: Expensive (braces from Myomo being the cheapest, range from 5-8k) According to the University of California, Irvine, a brace could end up setting you back as much as 100,000 dollars Lots of time and money spent on multiple consultations with doctors Lots of time and money spent on multiple fittings with prosthetic specialists
C. Why our device is more marketable The current Myomo brace and other neuro-robotic competitors can cost anywhere from $5k-$110k (UC, Irvine), due to the highly customized nature of the devices. Our device would be a neuro-robotic/myoelectric prosthetic brace that would be available in a range of standardized sizes (XS, S, M, L, XL) and 3D printed, with stick on electrodes replacing the high tech sensors, thus eliminating the need (and massive amounts of money spent) on multiple fittings, consultations, and neurologists/orthopedic doctors (Halber). The cost for the patient would be around $1000.

Patent Number: US 20140142474 A1
Title: Powered orthotic device and method of using same
Summary: A wearable orthotic device that has a brace, an EEG sensor, and an electrically powered communication system that provides system parameters to control operation of the actuator assembly. The system is comprised of a control unit that uses a processor. This processor can adjust the systems parameters based on the user selection. The control unit includes an auto-calibration mode that can be used when the muscles are at rest. An initial EEG signal level is measured by the EEG sensor and is then used to adjust the EEG signal level.

Patent Number: US20130046394 A1
Title: Systems and methods of myoelectric prosthesis control
Summary: The invention was a myoelectric prosthesis control system that includes a gel liner. This liner has multiple layers and leads partially between each layer. There can also be multiple electrode coupled to the leads and also be positioned between the layers. Some of the electrodes have an electrode pole that contracts the residual limb to detect electromyographic signals.
