  1. * The confident level of significance is 95% (p < 0.05) for repeated measures ANOVA
  2. The angles (mean ± standard deviation) of the thoracic and lumbar curves in the sagittal and coronal planes. (Positive value represents flexion or right side bending; negative value represents extension or left side bending; NF: without feedback, F: with feedback)
