Abstract: To produce relaxation of paravertebral muscles exhibiting contracture a relaxation device is used having several principal horizontal parallel strips (1) of adhesive tape that are joined together in pairs by several secondary or traction vertical parallel strips (2) of adhesive tape. The self-adhesive side of the principal and secondary strips (1,2) is protected by a removable sheet of siliconized paper (4). The vertical strips (2) are designed to be fixed to the patient's back in equal numbers on either side of the spinous processes and in line with the subjacent paravertebral muscles exhibiting contracture and said horizontal strips (1) being designed to ensure correct anchorage of the device to the patient's trunk.
