Each direction (lordosis and kyphosis) and system (ST=ShapeTape and O=Optotrak) indicated by posture. Data presented as: mean ± standard deviation (range).

1

Not all participants had a detectable lordosis in each posture; therefore, ‘n’ indicates the number who did. Kyphosis was always present.

2

Only one participant had detectable lordosis in slouched posture, values provided.

3

One participant’s data was not included in the extension analysis due to the lack of visibility of an Optotrak marker.
