This talk will summarize over a decade of research into muscle spindle response to spinal manipulation. We will discuss the relationship between biomechanical characteristics of SM (i.e. thrust duration, thrust amplitude, tissue preload, and thrust contact site) and trunk muscle spindle discharge. We will also discuss muscle spindle response to the use of commercially available SM devices that deliver manipulative thrusts over extremely short durations of 2-3ms, compared to manually delivered thrust durations of 100-150ms. Finally, we will discuss the latest research findings related to how chemosensitized muscle pain environments (induced by nerve growth factor) impact muscle spindle response to muscle stretch and spinal manipulation.
