Abstract:

Rapid fine motor control measurements of the hands can be used to indicate the presence of concussions/mild traumatic brain injury (mTBI) events without requiring baseline measurements. By comparing the individual reaction times of the hand's digits, a strong correlation can be shown to exist with variations between the fingers and thumb and concussion/mTBI. Receiver operating characteristic curve analysis provides a 97% predictive probability for mTBI without requiring a baseline measurement for the reaction times. These measurements are made every 1 millisecond for 3 digits (thumb, index, and small fingers) simultaneously, and they appear to indicate severity of injury as well as rate of recovery, which would provide an objective "return-to-play" scale in sports.
