A multi-direction operable massage chair includes a seat positioning device; a seat sensor of a limit member; a neck massaging device; a shoulder massaging device, and an arm massaging device together configured to move along a main rail in the y-axis direction; a back massaging device; a leg positioning device; a vibrational massaging seat including an adjustment member and two adjustment cylinders; a plurality of roller members configured to roll in different directions; first, second, third, and fourth infrared temperature sensors configured to sense temperatures of the arms, the neck, the back, and the legs of the user respectively; a board adjustment member of the leg massaging device configured to extend or retract; a board of the leg massaging device configured to rotate; and a pivotal armrest link.

The invention is embodied in an apparatus for extending the human back. The preferred apparatus has a frame of transverse and longitudinal members, and a roller 20 rigidly supported from below by a transverse member. The space above the roller and frame is open so that a user can lie face up on the roller and grab the longitudinal members with each hand to extend the back over the top of the roller. The user then lowers his hips to extend the spine as much as desired. The user can roll the spine, vertebrae by vertebrae, from the base of the occipital to the sacrum.

A massage ball assembly is for a massage chair. The massage ball assembly includes: a main frame; one or more tilting frames mounted to be rotatable with respect to the main frame; massage balls each mounted on the one or more tilting frames; and heating balls each mounted on the one or more tilting frames.
