Quantifying Effects of Non-Invasive Interventions to Reduce Low Back Dysfunction

Five normal subjects (two females, three males) were evaluated twice on the same day, and five patients with low back problems (four females, one male) were evaluated with the A-ATM before and after each of two treatments, with approval by NJIT IRB. The ATM rotates a passive supine subject’s pelvis, collecting torsion data that plots a hysteresis loop. By measuring the displacement as the loads are added and removed the rotational stiffness can also be determined using this device. This rotational motion is shared among numerous structures such as myofascial tissues, sacroiliac joints, thoracic, and the lumbar spine [1]. This device was developed to mimic the pelvic roll technique used by osteopathic physicians.
