Table 6.

Medians and interquartile ranges of total inclination and lumbar, thoracic and sacrum/hip inclinations in degrees measured before and after the intervention in sitting position in the sagittal plane: upright (U), flexion (F), extension (E), and estimated ROM from upright to flexion (U–F), upright to extension (U–E) and extension to flexion (E–F) (n = 76).
