Concussion Pen Screening Tool

Use of the Concussion Pen in Evaluating Ocular-motor Function in the Concussed and Non-concussed Populations Ages 11 to 18 Years Old.

To compare the use of the Concussion Pen to current clinical care practice. This will be a prospective study of a maximum of 24 subjects, with a goal enrollment of 20 subjects (10 in each cohort). All subjects will undergo clinical evaluation for concussion and will also be evaluated using the Concussion Pen. Randomization to being evaluated using clinical care first then the Concussion Pen and vice versa will be utilized. This randomization will help to control for evaluation fatigue on the part of study participants.

This will be a prospective study of a maximum of 24 subjects, with a goal enrollment of 20 subjects (10 in each cohort). All subjects will undergo clinical evaluation for concussion and will also be evaluated using the Concussion Pen. All subjects (both controls and concussion patients) will undergo all eye tracking measurements. Randomization to being evaluated using clinical care first then the Concussion Pen and vice versa will be utilized.

This will be a multi-disciplinary team with members of Physical Therapy (PT)/ Occupational Therapy (OT), Medical Doctor (MD), Doctor of Osteopathic Medicine (DO), and Doctor of Philosophy(PhD)s who specialize in concussion assessment. This study will include a population of concussed patients as well as non-concussed patients (controls) who will be seen in CM clinics per standard of care.
