Preclinical models of pediatric post-traumatic epilepsy (PTE) are lacking. We hypothesized that traumatic brain injury (TBI), induced by controlled cortical impact, in immature rats would cause electroencephalographic (EEG) epileptiform activity and behavioral seizures. TBI or sham craniotomy was performed on postnatal day 17. Using video-EEG monitoring 4-11 months post-TBI, most TBI rats (87.5%) showed EEG spiking and one had spontaneous, recurrent seizures. Controls showed neither EEG spikes nor electrographic/behavioral seizures. Late seizures were rare after TBI, but EEG spiking was common and may represent a surrogate for PTE.

The results of this systematic review demonstrated that little is known about PALs of individuals with TBI. PALs of participants with TBI were less than required for health maintenance. Self-efficacy to exercise and motivation were the most frequently identified facilitators of PA in the TBI population.

PALs decreased significantly on discharge from hospital and remained below inpatient levels despite physical capacity for higher PALs. Motivation, fatigue and anxiety were important influencers of PALs during the transition home period.
