The aim of this study was to investigate the effect of a 4 week period of Power Plate training on the spasticity of the quadriceps muscle in Spinal Cord Injury (SCI) patients. 16 individuals with spastic quadriceps hypertonia due to chronic SCI participated in this study. All participants performed a Power Plate training 3 times a week for 4 week. The 12-session intervention of Power Plate training was found to be associated with a statistically significant reduction of quadriceps spasticity.
Conclusion: The results show that use of Power Plate is associated with decreased quadriceps spasticity in individuals with spastic hypertonia due to SCI, in individuals in whom spasticity interferes with function. The effects persist for several days, suggesting that Power Plate may be useful prior to motor rehabilitation interventions to enhance the effects of training.
