MECHANISMS AND EFFECTS OF MANIPULATION:PREVIOUS THEORIES

This is a nice review of the theories of manipulation. Read it through and see how it helps you to develop your understanding of the role of manipulation.

MECHANISMS AND EFFECTS OF SPINAL HIGH-VELOCITY, LOW-AMPLITUDE THRUST MANIPULATION:PREVIOUS THEORIES

Evans, David, 2015

Objectives:

To discuss previous theories and research of spinal HVLAT manipulation, highlighting reported neurophysiologic effects that seem to be uniquely associated with cavitation of synovial fluid.

Data Source:

Medline and Embase

Data Synthesis:

The main hypotheses for lesions that respond to HVLAT manipulation were discussed: (1) release of entrapped synovial folds, (2) relaxation of hypertonic muscle, (3) disruption of articular adhesions, and (4) unbuckling of motion segments.

Results:

2 modes of action from zygapophyseal HVLAT manipulation. Intraarticular “mechanical” and “neurophysiologic” effects. Cavitation should not be an absolute requirement for the mechanical effects to occur but may be a reliable indicator for successful joint gapping.
