What are the neurophysiological effects of SMT in symptomatic & asymptomatic humans?
- RRS Education
High-velocity, low-amplitude spinal manipulation (HVLA-SMT) is frequently used for the management of many musculoskeletal and neurological conditions. Although SMT’s effectiveness in decreasing pain and disability has been found similar to analgesics, physical therapies and exercises, the mechanism(s) of action are not yet well understood. Neurophysiological effects are thought to play a primary role and certainly represents a fruitful area for existing and future research.
First thing’s first - we have to assess where we are with the literature! Existing studies have suggested the mechanical input of HVLA-SMT primarily affects afferent neurons in the paraspinal tissue and triggers neurophysiological responses in the peripheral and central nervous system, leading to pain inhibition. Other studies have suggested HVLA-SMT may increase pain-pressure thresholds and result in changes in Substance-P, neurotensin, oxytocin, interleukin, and cortisol levels.
The aim of this systematic review was to summarize the current state of the literature regarding the neurophysiological effects of HVLA-SMT in asymptomatic and symptomatic humans…LOG IN OR SUBSCRIBE TO ACCESS THIS REVIEW!
