Neurotrophin expression with acute or delayed exercise after SCI. (A) Western blot data demonstrates the presence of comparable levels of BDNF in the lumbar spinal cord when cycling exercise was initiated 5 days after injury (acute) or 28 days after injury (delayed). (B) Frequency dependent depression of the H reflex was restored in spinalized rats that received acute or delayed cycling exercise. Together these observations demonstrate the potential for exercise dependent plasticity in the injured spinal cord at short and long intervals after SCI.
