USF inventors have developed a new measurement tool to test for vibratory sense in lower and upper extremities with great accuracy. This novel invention consists of an electronic indicator with a push button for user input. Upon the first feeling of vibration, the person will push the button, and will again push the button when the vibration stops. Therefore, this device more accurately produces a measurement for vibration. The vibration amplitude will also follow a set pattern. Therefore, the time that the device runs for will be indicative of the amount of sensation transmitted. This test could determine the threshold of sensation more accurately than a tuning fork by honing in on the amplitude that is felt.
