This study investigated 238 consecutive admissions to an adult head trauma unit during six years. Eighty-seven patients with posttraumatic epilepsy (PTE) were identified. Rehabilitation outcome was measured by a locally developed rating scale obtained at admission and discharge for all head trauma patients. The PTE and non-PTE groups were comparable in terms of demographic and medical characteristics except for proportion of men, which was higher in the PTE group (84% vs 66%, p less than .05). Both groups demonstrated significant functional gains on all measures during the course of their hospitalization (p less than .01), although the PTE patients demonstrated lower levels of function at admission and discharge on items rated by physical, occupational, speech, and recreation therapists, and by psychologists. Furthermore, PTE patients required a higher level of nursing care on discharge (p less than .05). It appears that PTE does not impede the rehabilitation process but significantly impacts posthospital rehabilitation plans of patients with blunt head injuries.
