Two point discrimination lanyard device

Case ID:
Web Published:

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.

Patent Status: A US design patent was filed June 3, 2020.
