An adjustment with the Sigma Pro Adjuster produces a quick thrust similar to the way a chiropractor uses their hands to adjust the vertebrae in your back. The benefit of the instrument is that it performs a high-velocity, low-amplitude motion that is targeted to a very small area, releasing trigger points that are often the cause of muscle spasms.
As opposed to traditional chiropractic adjustment techniques, the Sigma Pro Adjuster does not cause the same popping and cracking noises that can make some people feel uncomfortable. It is a gentle, mechanical method of easing the joints back into alignment, and it works on a wide range of body areas, not only on the spine.
Several studies have shown that instrument adjusting is just as effective as traditional chiropractic techniques for easing pain and increasing range of motion in patients who have sought chiropractic care. Its speed, gentleness and accuracy are also recommended for populations that may have trouble with the use of traditional chiropractic techniques, such as children and the elderly. The use of instrument adjusting, such as with the Sigma Pro Adjuster, allows for fewer side-effects and less post-treatment muscle soreness.
