abstract = {Rehabilitation is widely recognized as an essential
component in evaluating the effectiveness of a therapeutic
intervention in animal models of translational spinal cord
injury research. Ideally, the rehabilitation method used
should be optimized for the specific injury model and
severity to adequately compare the efficacy of the
investigational therapy. For studies utilizing thoracic
spinal cord injuries, rehabilitation primarily involves
bipedal or quadrupedal treadmill training aimed at restoring
hindlimb function. Previously, we reported modest
improvements to hindlimb motor recovery following forced
bipedal treadmill training after moderate 175 kilodyne
thoracic spinal cord contusion injury, which were further
enhanced when combined with the microtubule-stabilizing drug
epothilone B. However, during this and other studies we have
noted that B-TMT presents several potential limitations,
including brief periods of active rehabilitation for each
animal, variability between animal handlers, animal stress,
and the focus on a single movement pattern. To overcome
these limitations, we investigated the effects of an
environmental enrichment-based rehabilitation that differs
from a general environment enrichment strategy by including
task-specific training elements, something we have termed
'targeted environmental enrichment'. This method provides
longer periods of active rehabilitation, operates
independently of the animal handler, thereby involves less
animal handling, which minimizes stress, and encourages a
wide range of movements. Our findings indicate that targeted
environmental enrichment outperforms bipedal training across
several behavioural measures which produced a ceiling effect
that epothilone B could not overcome. Therefore, these
results suggest that targeted environmental enrichment may
be a more effective rehabilitation approach than B-TMT and
should be considered for application in models of severe
spinal cord injury.},
