Whole-Body Vibration Improves Functional Recovery in Spinal Cord Injured Rats
2013
Abstract Whole-body vibration (WBV) is a relatively novel form of exercise used to improve neuromuscular performance in healthy individuals. Its usefulness as a therapy for patients with neurological disorders, in particular spinal cord injury (SCI), has received little attention in clinical settings and, surprisingly, even less in animal SCI models. We performed severe compression SCI at a low-thoracic level in Wistar rats followed by daily WBV starting 7 (10 rats) or 14 (10 rats) days after injury (WBV7 and WBV14, respectively) and continued over a 12-week post-injury period. Rats with SCI but no WBV training (sham, 10 rats) and intact animals (10 rats) served as controls. Compared to sham-treated rats, WBV did not improve BBB score, plantar stepping, or ladder stepping during the 12-week period. Accordingly, WBV did not significantly alter plantar H-reflex, lesion volume, serotonergic input to the lumbar spinal cord, nor cholinergic or glutamatergic inputs to lumbar motoneurons at 12 weeks after SCI.
