Mild traumatic brain injuries usually require no treatment other than rest and over the counter pain relievers for headache. A person should be monitored closely for any persistent, worsening, or new symptoms. It is recommended to avoid physical activity and cognitive activities until symptoms have stopped. Other treatment techniques may be utilized to treat impairments such as dizziness, ocular motor function, decreased balance, and gait. Techniques most frequently provided in vestibular rehabilitation include gaze stabilization exercises including maintaining a fixed gaze while turning the head side to side; standing balance with and without eyes closed and with different stances and surfaces; walking with balance challenges including walking with head turns, tandem walking, and obstacle avoidance. Canalith repositioning maneuvers may also be used.
