Sigma Instrument
The Sigma Instrument utilizes a precise oscillating force with uninterrupted motion. It is able to increase the mobility of the spinal vertebrae and other joints by reducing or eliminating the fixations.
It makes use of soft tips, which are comfortable to the human body, to exert a tapping force that decreases local muscle tension and "unstick" the joint. It is comfortable and precise, and occurs faster than the muscles can contract in response to the test.
