Massage airbags enable massage chairs to expertly imitate physical compression techniques used by professional masseuses. Massage therapists grip and tightly squeeze muscles before releasing them to prompt these tense muscles to relax, the primary objective of compression massage.
Most airbags tend to be located in the foot and calf rest, as compression massage promotes better circulation and reduce swelling, which are normally treated with passive methods like compression socks. By extension, shoulder and arm airbags produce comparable effects as they too stimulate blood-flow in a wave-like motion towards the heart.
High end models of massage chairs have acquired the ability to manipulate the movement of the body with the incorporation of waist airbags, which alternatively inflate and deflate on each side of the lower back to enhance rotation and motion.
This major advancement has been advocated to have a real remedial benefit for the soft tissues of the lower back. Nevertheless, airbag massage tends to be an issue of personal preference, as decisions regarding the desired placement and intensity of compression airbags is a highly individual one.
