- The Defense and Veterans Brain Injury Center
- Brief Summary
Context: Traumatic brain injury (TBI) is a common condition associated with significant long-term cognitive, behavioral, and functional morbidities. There are minimal controlled efficacy data of various acute rehabilitation intervention approaches.
Objective: To determine the relative efficacy of two different acute TBI rehabilitation approaches - cognitive-didactic versus functional-experiential. Secondarily to determine relative efficacy for different patient subpopulations based on baseline cognitive functioning.
- Detailed Description
A randomly assigned, intent-to-treat model of two different comprehensive treatment programs conducted between July 19 1996 and May 16, 2003 in 360 adult participants with moderate to severe TBI treated in four participating Veterans Administration TBI rehabilitation centers.
All patients admitted to the Commission for Accreditation of Rehabilitation Facilities (CARF) accredited acute inpatient rehabilitation brain injury programs at 4 participating Veterans Administration Medical Centers (VAMCs) (Minneapolis, Palo Alto, Richmond, and Tampa) during the study enrollment period were screened for eligibility.
The design was a randomized-controlled trial with two treatment arms (cognitive-didactic and functional-experiential), both embedded within an interdisciplinary TBI rehabilitation program. All treatment was hospital based. The interactive nature of the experimental conditions precluded subject blinding. Since each participating site serves a wide geographic area, the protocol permitted post-hospital outcome assessments by structured telephonic interview, to minimize drop out.
Participants completed baseline assessment then received by random assignment one of the two standardized protocol rehabilitation programs (summarized below and described in detail elsewhere). Participants received 1.5 to 2.5 hours daily of protocol-specific therapy plus another 2 to 2.5 hours daily of occupational and physical therapy. Independent teams of therapists functioned at each site to deliver the separate treatments and by necessity were not blinded to treatment. Protocol monitoring site visits, biweekly conference calls, and biannual investigator meetings were conducted to ensure uniformity of protocol treatment over time.

Group Intervention Description Cognitive-Didactic Rehabilitation Developed by Sohlberg \& Mateer to target four cognitive domains often impaired by TBI: attention, memory, executive functions, and pragmatic communication. Subjects practiced progressively more difficult paper-and-pencil or computerized cognitive tasks in 1:1 cognitive therapy sessions (1.5-2.5 hours daily). Functional-Experiential Rehabilitation The works of Giles and Clark-Wilson and Hartley guided the basic concepts and treatment of the functional-experiential arm (Functional). The objective of the functional protocol was to use real life performance situations and common tasks to remediate or compensate for functional deficits after brain injury. Functional protocol treatment interventions (1.5-2.5 hours daily) typically occurred in group settings and natural environments (hospital recreation areas, group rooms, simulated home environments in the dining room, community outings, etc.).
- Primary Outcome Measures
Name Time Method (1) Functional independence (i.e., ability to live independently with less than 3 hours of assistance per week) (2) Return to work/school (i.e., paid employment or school enrollment, either full or part time) One-year Follow-up
- Secondary Outcome Measures
Name Time Method The Functional Independence Measures (FIM)33, 34 consisting of motor and cognitive scores and the Disability Rating Scale Score (DRS)35 were measured. Discharge from Protocol Treatment Quality of life, psychosocial function, behavioral, and mood state measures One-year Follow-up
