Cervical traction. A comparison of sitting and supine positions.

Eight students were studied todetermine the position which provided the greatest amount of posterior intervertebral separation during a cervical traction treatment. A standard angle of 45 degrees with traction apparatus set at zero, 14 Kg (30 pounds), and 18 Kg (40 pounds) were used in both sitting and supine positions. Measurements of posterior intervertebral separation taken from lateral roentgenograms of the C4-C7 vertebrae revealed greater separation in the supine positions. The results suggested that the supine position was more beneficial in treatment of the cervical spine with traction. The investigators concluded that the increased separation in the supine position was related to the patient's increased comfort and relaxation.
