Dr. Catena’s first research line in his graduate studies directly addressed motor performance (typically balance control) deficits that individuals with concussion display. Prior to our research, clinicians placed more significance on cognitive deficits in diagnosis and treatment. These publications showed that there are significant motor performance deficits following a concussion and these deficits typically result from certain cognitive impairments. This body of work was significant toward our understanding of how cognitive impairments can increase the risk to subsequent concussions by altering motor skills.
