The authors wish to clarify and correct two comments made in the discussion section of this article.
1. | It was remarked that spinal height (SH) recovery after performing chair-care exercise (supported dynamic lumbar extension posture) reported by Fryer, Quon, and Smith (Citation2010) (+ 198.46%,+ 12.9 mm, 95% CI: 6.4, 19.3 mm) was much higher than SH recovery obtained from the present study (+ 22.48%, + 0.78 mm, 95% CI: 0.03, 1.54 mm) . It is clarified that the percentage SH recovery was calculated as follows: |
2. | The article suggested that this finding might be due to the stadiometry configuration in the Fryer et al. study being different from the present study. This comment was inaccurate and a result of the authors inadvertently referring to the methods in Fryer and Zhang (Citation2010) instead of Fryer, Quon, and Smith (Citation2010). The commentary in the online version of the original article has now been amended as follows: |
The authors apologise for this error and wish to acknowledge Jerome Fryer DC for drawing it to attention.
