Fig 2 Tracing of spinal curves from C7 to S2, in slump supported sitting and upright unsupported sitting, in an asymptomatic subject. Measurements of the depth of (a) thoracic and (b) lumbar curves from the vertical alignment were made as indicated by the horizontal lines. Legend: a1, depth of the thoracic kyphosis in upright unsupported sitting; a2, depth of the thoracic kyphosis in slump supported sitting.

Fig 3 Changes in electromyographic (EMG) muscle activity in 3 different sitting postures—slump supported, upright unsupported, and very tall sitting—in asymptomatic (black box) and symptomatic subjects (white box). Abbreviations: LOE, left obliquus externus abdominis; LOI, left obliquus internus abdominis and transversus abdominis; RA, rectus abdominis; ROE, right obliquus externus abdominis; ROI, right obliquus internus abdominis and transversus abdominis. *P<.05 comparison between postures; †P<.05 for comparison between groups.
