Background Environmental enrichment (EE) is a complex living milieu that has been shown to enhance functional recovery vs. standard (STD) housing after experimental traumatic brain injury (TBI) and therefore may be considered a rodent correlate of rehabilitation. However, the typical EE paradigm consists of continuous exposure to enrichment after TBI, which is inconsistent with the limited time frame in clinical rehabilitation. Objective To determine whether abbreviated EE (i.e., rehabilitation-relevant dose response) confers benefits similar to typical EE after TBI. Methods Adult male rats received either a controlled cortical impact (2.8 mm depth at 4 m/sec) or sham injury and were then randomly assigned to TBI + EE, TBI + EE (2hr), TBI + EE (4hr), TBI + EE (6hr), TBI + STD, and respective sham controls. Motor (beam-balance/beam-walk; BB/BW) and cognitive (Morris water maze; MWM) performance was assessed on post-operative days 1-5 and 14-19, respectively. Results The TBI + EE (2hr) and TBI + EE (4hr) groups were not statistically different from the TBI + STD group in any behavioral assessment. In contrast, the TBI + EE (6hr) group exhibited significant enhancement of motor and cognitive performance vs. the TBI + STD group, as well as the TBI + EE (2hr) and TBI + EE (4hr) groups (p < 0.003), and did not differ from the TBI + EE (typical) group. Conclusions These data demonstrate that abbreviated EE (6hr) produces motor and cognitive benefits similar to continuous EE after TBI and thus may be considered a dose-relevant rehabilitation paradigm.
