A new tool in the field of neurological examinations

For over 100 years, reflex hammers have been used for performing routine neurological examinations. However, the force of each tendon strike and the resulting reflex is subjective to how hard the clinician swings the hammer. Even professional athletes have trouble duplicating the same swing twice in a row! This is a problem for establishing reflex trends over time or when multiple practitioners are examining one patient. RFX Corporation set out to disrupt the industry with real-time force measurement that eliminates measurement ambiguity. The tool needed to be inexpensive to manufacture, achieve the required measurement range and accuracy, and not impact the hammer's weighting or how it is used. Working closely with the RFX team, WTI performed months of testing to validate the concept on a custom-built test rig.
