There are multiple approaches to joint mobilization and manipulation.  Each of these approaches has its own unique set of theories.  The techniques utilized in the Multi-system Approach are those taught by the American Academy of Manipulative Therapy & Spinal Manipulation Institute.  This approach to joint mobilization and manipulation is based on the most current scientific research.  When normal joint motion is not occurring in the spine or extremities, these techniques can be performed to allow normal joint movement by resetting the neuromuscular system.  With a reset of this system, exercise and other treatment modalities can provide a more total effect.
