Figure 4. Subjects with ideal posture (A) reported the least amount of pain in the lumbar region.

Subjects were asked to rate pain in the cervical, lumbar and thoracic regions on a scale of 0–10, with 10 signifying the most painful condition. There was no significant correlation between cervical and thoracic pain with posture. All other subjects, except for those in ideal posture, experienced more pain in all the observed areas. (A, Ideal posture; B, Kyphosis-lordosis posture; C, Flat back posture; D, Sway-back posture).
