ECMC Outpatient Rehabilitation
The Erie County Medical Center includes an advanced academic medical center with 602 inpatient beds, on-and off-campus health centers, more than 30 outpatient specialty care services and Terrace View, a 390-bed long-term care facility. ECMC is the regional center for trauma, burn care, behavioral health services, transplantation, and rehabilitation and is a major teaching facility for the University at Buffalo. Our amputee program includes pre-prosthetic training, prosthetic prescription, and prosthetic training. The prosthetic team includes a rehabilitation medicine physician, prosthetist, and physical therapist who meet regularly to evaluate patients and make recommendations.

Project lead (if different from primary):
- Project Title: Rapid Design of a Pre-prosthetic for Upper Extremity Amputee
- Project Background
The design and final configuration of a permanent prosthetic typically takes multiple months (up to a year) to be finalized. In the meantime, it is critical for patients to rehab using a “pre-prosthetic” device as soon as possible. Rehab includes the ability to perform basic functions like, eating with a fork and spoon, brushing teeth, baking and performing a variety of exercises using weights. In addition to recent amputation patients, there are increasingly individuals seen at ECMC that have been without a prosthetic for months or years. The ability to provide an inexpensive pre-prosthetic to rehab or retrain is an important capability that ECMC does not have the ability to provide.
The objective of this project is to rapidly design and build a pre-prosthetic for two patients who have amputation sites above and below the elbow. The new design should be an improvement over the design shown in the figure, which is representative of the pre-prosthetics that ECMC is limited to producing. The design solutions should give consideration to the following attributes: • An adjustable cuff that provides a sufficient holding force • An elbow joint that is easy to loosen/tighten and holds without slipping during activities that include lifting up to fifty pounds • A joint which provides functionality/motion similar to a wrist joint, but can be locked into position for each activity • End-effector(s) that support various activities, like: using fork/spoon, brushing teeth, holding weights, squeezing a ball between both hands/arms
- Expected Deliverables
The expected short term deliverable is the design and fabrication of a pre-prosthetic, inclusive of CAD models, basic analysis, technical documentation and fabrication of the devices. The final design documentation must be developed in accordance with the standard represented in the design catalog [http://designcatalog.eng.buffalo.edu/index.php/Prosthetic_Design_Catalog]. All design documentation will be uploaded to the catalog for future use and additional development.
- Tentative Timeline
Total time is about 10 weeks. Ideally the initial pre-prosthetics would be delivered to the patients in late June or early July. This assumes leveraging existing design concepts be developed during the Spring 2017 semester. Final designs should be uploade
