  1. a Evaluated in three categories: decreased thoracic kyphosis (flat back), normal kyphosis or hyperkyphosis
  2. b Sum of all thoracic spine motion segments recorded as hypomobile
  3. c The Bland Altman plots for each item are presented in the additional electronic files of this study; none of the linear regression for proportional bias were statistically significant
