Abstract
Given the importance of validity and reliability of measurement instruments, determining the validity and reliability of the photogrammetric method as an alternative to radiography is of great importance. Therefore, the purpose of this study was to evaluate the validity and reliability of digital photogrammetry in determining the degree of thoracic hyperkyphosis in Iranian adolescent girls and boys.
This study was a cross-sectional research with a reliability and validity study design. The participants were 40 girls and boys with thoracic hyperkyphosis who diagnosed by a spine specialist and refereed to the Integrated Rehabilitation Center of the Red Crescent for receiving corrective exercise or bracing services. In order to determine validity of photogrammetry for determining of hyperkyphosis degree, the measures compared with radiography of the subjects. Furthermore, to study the reliability of photogrammetry, all the measurements were done within 24-48 hours after the first imaging and the results have been compared. The correlation test was used for the analyzing of the reliability and Inter-rater correlation used for validity analysis.
The result of the current study showed that the photogrammetry method for determining the degree of thoracic hyper-kyphosis had accepted validity (P=0/001, r=0/64) comparing with Radiography. Also, this method had a high inter-examiner reliability (P=0/001, r=0/96).
The current study showed that all the relative specialists (Orthopedics, Spine, Physical Medicine along with therapists in the areas of physiotherapy and Corrective Exercises) can use the photogrammetry data as the complementary information when measuring the degree of hyperkyphosis in order to decrease the X-Rays damages.
