OHSU # 2782 — Two point discrimination lanyard device
Technology Summary: A new tool for evaluation of hand sensory nerve function.
Problem: For the objective assessment of hand sensory nerve function, two-point discrimination has been the standard. It is a non-invasive test performed by hand surgeons using a simple, hand-held device. Current devices are large, and difficult to carry and store due to multiple small pins extending from all sides. The cumbersome current device has led practitioners to use a bent paper clip leading to inaccurate examinations.
Solution: The new OHSU device has a reduced size with shared sensory pins incorporating a loop for a lanyard or ID badge. The addition of a visual scale of angles improves range of motion measurements. The ability to carry the device on a lanyard reduces the chances of accidently piercing the provider when carried in a pocket.
Potential advantages of the OHSU device includes:
Small overall size creating increased portability;
Ability to connect to ID badge;
Visual scale of angles to improve range of motion measurements.
License Status: Available for non-exclusive or exclusive licensing.
