Of the approximately 1.3 million (1) people, diagnosed annually with a mild traumatic injury, like concussion, 80% to 90% follow a normal recovery course with full symptom resolution within 3 months of injury.(2,3) The remaining 10% to 20% who are refractory to conventional care may have persistent post-concussion impairments lasting months to years.(4,5) These impairments can include poor performance on divided-attention and dual-tasks activities that combine physical demand (ie, balance and gait) with cognitive loads.(6,7)
Mild traumatic brain injury can compromise reaction time, visual perception, memory, attention, balance, and gait. These deficits, especially if persistent, can restrict participation in daily activities and the resumption of personal and profession roles. (8)
Treatments for motor vehicle accident injury concussion, slip and fall concussion or mild traumatic injury concussion consisted of clinical techniques including optokinetic stimulation, vestibular rehabilitation and postural stability exercises, targeting specific impairments.
After a month treatment, most patients demonstrated significant increases in postural and gait balance with a near complete resolution of all post-concussion symptoms. They successfully returned to normal daily life.
