Two previous presentations at the BIATX discussed ongoing use of a non-invasive medical device for early detection and screening for mTBI. This device provides a way to use physiological measurements measured by the Head Impact Trauma ScreenSM (HITS) to determine the presence and differentiation of subconcussive and concussive events. Measurements are based on changes in the fine motor control of the hands. Our case reports measured: 1) subconcussion observed and initially taken approximately 30 minutes after head impact from a fall and 2) repeated subconcussions from athletic activities. Both cases demonstrated fine motor and sensory control deficits, and both recovered completely and returned to their individual baseline measurements. HITS results for both cases are compared to 1) a control (no head injury), 2) a case of mTBI, and 3) a clinically documented brain-injured person to illustrate the graduated severity of mTBI, ranging from subconcussion to concussion based on non-invasive measurements.
