Active thoracic kyphotisation: modifications in the shape of the trunk

Results In NP, the average measure of thoracic kyphosis was 37.8°±11.2. In comparison to the normal position, the extent of thoracic kyphosis actually increases when the patient tries actively to emphasize it, both during an inspiratory (43.7±10.4), and an expiratory (45.6±39.7), phase. The average area of the hump doesn’t change significantly: 6.4±3.5 in NP, 6.5±3.5 in SC, 6.5±3.0 during KI, 6.5±3.1 during KE. The pattern of modification of the hump area is unclear. In 23% of subjects, we find the highest hump in NP, in 28% of patients in SC, in 28% during KI, and 21% during KE. The average value of lumbar plumbline distance (PD) is 40.3 in NP, 27.0 in SC, 61,4 during KI and 63.4 during KE. The average value of cervical PD is 29.4 in NP, 24.8 in SC, 27,9 during KI and 28.9 during KE.
