  1. SD Standard deviation; Th Thoracic; df Degree of freedom
  2. a The difference between sitting and standing measurements were evaluated with paired-samples t-test
  3. b Negative values represent thoracic extension
  4. c Negative values represent increased thoracic kyphosis (i.e. flexion) while trying to extend the thoracic spine
  5. d Negative values represent inability to extend thoracic spine (i.e. thoracic spine remains in flexion while trying to extend it)
