Study Arms:
- Osteopathic Manipulative Therapy (OMT) Treatment Group (Type: EXPERIMENTAL): Initial concussion treatment will involve OMT in addition to standard of care treatment. The OMT practitioner, using a strong anatomic knowledge base, applies specific genital forces in the dysfunctional area, thus providing aid to the body's innate mechanisms of healing. During OMT, a patient's muscles and joints are moved using techniques that include stretching, gentle pressure, and resistance.
- Standard of care concussion treatment group (Type: ACTIVE_COMPARATOR): Standard of care concussion treatment without OMT
