The effect of soft tissues in measurement of thoracic kyphosis by Iranian kyphometer

The aim of this study was to evaluate the effect of soft tissues in measuring thoracic kyphosis by Iranian kyphometer through placement on the body and on the X-Ray and also comparing the results with with Cobb method.
The method of this study is Descriptive – correlation and it's sampling was targeted and vailable. The number of subject formed 18 persons. The measurements of each subject were Cobb angle with X-ray and kyphosis angle with putting kyphometer on the body and on the X-ray.
The result of this study showed, the high Validity and high correlation between measurement with kyphometer on body and on X-ray and Cobb method (p≤0.05), and also reported high correlation between measurement with kyphometer on body and measurement with kyphometer on X-Ray (p≤0.05). The comparison of the three methods in terms of mean; there was no considerable difference between the result of kyphometer on body and kyphometer on X-Ray and also between measurement with the kyphometer on X-Ray and Cobb method (P=0.34).
Based on the high correlation between the three measurement methods (kyphometer on the body, kyphometer on the X-Ray, cobb method) and also lack of significant difference between these three methods, we can say Iranian kyphometer is a valid device in measurement of thoracic kyphosis and soft tissues of the spine have no effect on the measurement by kyphometer.
