Use of Shiatsu Massage chairs are a good way to dissolve the knots in your back by melting away a trigger point with mechanical pressure. Trigger points tighten and cause back pain from overuse, working out or even stress. The newer electronic massage chairs have kneading robotic hands and massage heads that have been engineered to target, massage and decompress certain points on your back. These robotic massage chairs are very effective if you have trigger point pain from tension or overuse.
Most people that sit at a keyboard and desk for extended periods of time, hold tension in their upper and middle back which can create these knots of pain and tightness. Because their back muscles are held in an unnatural position for an extended time, the blood flow becomes stagnant. Stiffness and tightness begin to form from lack of oxygen and movement. Use of the massage chair can help get the blood flow and movement into the back. Many people who perform repetitive lifting or carrying activities at work or during exercise have pain in their lower back and can also develop these tender points. The pressure applied to these areas by mechanical manipulations of a massage chair break up the stiffness and gelling effects of these tight knots.
