The photogrammetric method and inclinometer-based measurements are commonly employed to assess the anteroposterior curvatures of the spine. These methods are used both in clinical trials and for screening purposes. The aim of the study was to compare the parameters used to characterise the anteroposterior spinal curvatures as measured by photogrammetry and inclinometry.Material and methods. The study enrolled 341 subjects: 169 girls and 172 boys, aged 4 to 9 years, from kindergartens and primary schools in Rzeszów. The anteroposterior spinal curvatures were examined by photogrammetry and with a mechanical inclinometer.Results. There were significant differences in the α angle between the inclinometric and photogrammetric assessment in the Student t test (p=0.017) and the Fisher Snedecor test (p=0.0001), with similar differences in the β angle (Student's t p=0.0001, Fisher Snedecor p=0.007). For the γ angle, significant differences were revealed with Student's t test (p=0.0001), but not with the Fisher Snedecor test (p = 0.22).Conclusions. 1. Measurements of i...

Concurrent validity of photogrammetric and inclinometric techniques based on assessment of anteroposterior spinal curvatures

“…The presented findings are not consistent with the research results reported by Walicka-Cupryś et al who assessed spinal curvatures with liquid-based inclinometer and photogrammetric technique [12,23]. These authors did not find the two methods to be compatible.…”

“…The results reported by various researchers are difficult to compare due to the fact that different methods and measuring tools are applied; therefore, it is necessary to continue studies designed to compare results obtained with specific methods. Among the specialist publications we can encounter articles discussing concurrent validity of various techniques designed for assessing body posture [12,[23][24][25]], yet no research has previously been reported to compare the methods based on photogrammetry and gravitational inclinometer, which has been done in the present study. The two methods were used in assessing the same subjects, which made it possible to verify the assumption regarding the concurrent validity of these measurements.…”

“…Additionally, this is the first study focusing on senior citizens with increased BMI, which made it possible to verify the accuracy of these methods in this group of patients. Previously conducted comparisons related to younger individuals with no excess weight [12,16], while measurements of spinal curvatures are necessary in older people or overweight individuals, and in fact assessments are more error prone in such cases. The inclinometer applied in this study is a small and affordable measuring tool.…”

“…In the literature, we can find studies designed to compare concurrent validity of two methods, e.g. Metrecom System and Saunders mechanical inclinometer [5], X-ray with photogrammetry [10], liquid-based inclinometer and phone application [11], photogrammetry and liquid-based inclinometer [12], or computer-assisted magnetic tracking device compared to inclinometer [13]. The first three reported high concurrent validity, contrary to the latter study.…”
