OHSU # 2782 — Two point discrimination lanyard device
A small wearable device for two-point discrimination testing of sensory nerve function.
Two-point discrimination is a standard objective assessment of hand sensory nerve function. It is a non-invasive test performed by hand surgeons using a simple, hand-held device. The device has two prongs a measured distance apart, and physicians move the prongs closer together until a patient reports feeling only one point of contact, thereby allowing for an assessment of sensory nerve sensitivity. 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.
The current device is an improved compact and wearable tool for administering the two-point discrimination test (see Figure). Benefits of the device include:
- Small overall size creating increased portability.
- Reduced number of sharable sensory pins to make the device easier to hold and store.
- Ability to connect to ID badge or lanyard to prevent user loss.
- Visual scale of angles to also allow for improved range of motion measurements.
This technology is available for licensing.
