Participants in this group will receive routine care for the management and treatment of concussions

Participants who are randomized into the OMT group will receive OMT in addition to their usual care.

Osteopathic manipulative treatment (OMT) is hands-on care provided by an osteopathic physician (D.O.). During osteopathic manipulative treatment, an osteopathic physician may move participants' muscles and joints using osteopathic techniques including stretching, gentle pressure and resistance, as well as thrust techniques that apply a quick, therapeutic force of brief duration that travels a short distance.

Symptom evaluation score is a self-reported measure of the participants' post-concussion symptoms. Participants are scored on Total Number of Symptoms (ranges 0 to 22) and Symptom Severity Score (ranges 0 to 132). Higher scores represent worse outcome.

Participants will be seated in an upright position with their upper body secured to a backrest and will wear a head harness with an attached position sensor. The angular position of the head will be displayed on a monitor 1 meter in front of the participants and they will be asked to follow a moving target by moving their head. Accuracy will be determined by taking the difference between the target position signal and the actual head position.
