Cullen, NK, Crescini, C, & Bayley, MT (2009). PM&R, Vol. 1 (12), pp 1069-1076.
Two groups of patients were compared: one of patients with traumatic brain injury (TBI) and one of patients with anoxic brain injury (AnBI) — damage caused when the brain receives inadequate oxygen for several minutes or longer (brain cells begin to die after approximately four minutes without oxygen). The two groups were matched for age, severity of injury, and length of acute care hospitalization. Patients who had an AnBI had a slower recovery rate compared with those who had a TBI. Physical recovery was also slower than cognitive recovery during inpatient rehabilitation for an AnBI.
