Health Care Issue

The health care issue we decided to study is Cerebral Palsy. Cerebral Palsy is a common disorder, affecting roughly 500,000-800,000 people in the U.S. alone. Cerebral Palsy is a disease in which abnormal brain development causes motor disabilities in childhood. The effects range anywhere from small motor disabilities to a required 24-hour assistance.1 The health issue we would like to solve is the process of eating as a child experience issues with Cerebral Palsy. We would hook up an exoskeleton to the patient's arm, the exoskeleton would detect how the patient is trying to move and would in turn move a robotic arm the right way with perfect stability. This would allow the patient to eat without the need of help, as well as perform tasks that they may otherwise be unable to complete. Not only would this create a level of self-independence, but it would also create the opportunity for the patient to feel accepted in the social realm as he/she would be able to complete the actions that others perform seamlessly.

Current Solutions Advantages Disadvantages
Neuromuscular Electrical Stimulation & Kinesio Taping Applications "Improves postural control and sitting balance in children" Only works for early stages of CP and loses its function after motion becomes more confined (usage)
Orthosis Improves children's ability to walk Doesn't always work (effectiveness)

Only useful for specific extremities (usage)

Lower Extremity Exoskeleton Improves/enables ability to walk Only works for a given amount of time (effectiveness)

Expensive (financial)

Medications such as Valium or Baclofen Can control symptoms such as spasms or stiff muscles Negative side effects such as fatigue, dizziness, and nausea (practicality)

Costly over time (financial)

Based on the current solutions, our technology would be more effective in treating CP because it can be used by both children and adults, will stimulate the nerves/muscles in the patients and help them improve their movement, and is intended to be more affordable.

Fundability Worksheet Scores


Our Score: 2

We believe we scored a two on the competitor Fundability Worksheet Score because there are competitors out there, however the other products that are aimed to help in the areas we are focused on are fairly new with very few on the market. Most competitors have products aimed at helping in areas like walking.

Customer Validation

Our Score: 1

We believe we scored a one on the competitor Fundability Worksheet Score because there is no customer feedback.

IP Position

Our Score: 1

We believe we scored a one on the competitor Fundability Worksheet Score because we have not filed a patent application yet, however we are able to patent our design.
