Directions
The subject will receive a single pulse to the right finger, starting a timer. As soon as the pulse is detected, click the left mouse button*. Once the subject has clicked, the timer will stop and the software will record and display the result. This test is a direct measure of reaction time, and it is essential that the subject responds as quickly as possible to the stimulus.
Testing Notes
If the patient does not feel the pulse (either because they weren’t prepared or took their finger off the stimulator), you may instruct them to simply click and move on to the next trial. For proper accuracy in reaction time measurement, please use a two-button computer mouse*, not a wireless mouse or laptop/external trackpad.
*When hardware response is enabled, you may respond to each question by depressing the corresponding stimulus tip.
