Shadow Moiré technique for postural assessment: qualitative assessment protocol by intra- and inter-rater evaluation

Abstract

[Purpose] This study aimed to develop and validate an assessment tool for Moiré topogram made specifically with the Shadow Moiré technique of the dorsum. [Subjects and Methods] In the analysis of topograms, frontal, sagittal, and transverse planes of individuals’ dorsal were considered. Two instructor evaluators analyzed the topograms at different times in the day and on different days. The measurements of intra- and inter- (intra- and interday) reliability were calculated. [Results] Of the three planes analyzed, in all analyses, good (0.61 to 0.80) and/or excellent (0.81 to 1) concordances were observed. [Conclusion] This analysis framework can be recommended to evaluate the topograms obtained with SMT.

Moiré topography as a screening and diagnostic tool—A systematic review

“…However, the assessment of the generated topograms on the basis of visual inspection and marking specific points on the patient’s bone body, may affect the accuracy of the measurements [ 7 , 19 , 44 ]. Due to the fact that the topogram is made in strictly defined conditions (i.e., constant distance, the exact position of the level, constants lighting conditions, the same parameters of the optical system) [ 8 ], this measurement should be repeatable.…”

“…These less reliable measurements of the spine in the sagittal plane can be justified, as most indirect methods are concerned with the univariate assessment and spine lesions are usually three-dimensional [ 45 , 47 ]. Although the MT does perform a three-dimensional analysis, it may be difficult for the assessor to see asymmetries in the sagittal plane due to the smaller sharpness of the fringes, especially in the cervical and lumbar regions [ 7 ].…”

“…This problem’s significance and its universality suggest the need to develop objective methods for diagnosing body posture. The gold standard in identifying changes in the spine position is the radiographic examination [ 7 – 9 ]. However, the disadvantage of radiographs is that repeated exposure to ionizing radiation may be harmful to patients [ 10 ].…”

Somatic determinants of changes in selected body posture parameters in younger school-age children

“…It is known and used mainly in Japan (the most advanced country in using this method), Poland, Brazil, Iran and eastern European countries (Bosnia and Herzegovina, Serbia) ( Grabara, Bieniec & Nawrocka, 2017 ; Silva et al, 2014 ; Kuroki et al, 2018 ; Taheri Tizabi et al, 2012 ; Kapo et al, 2018 ). Moreover, it is a reliable and repeatable method of posture evaluation ( Filho et al, 2017 ).…”

Physical Activity and Parameters of Body Posture in the Frontal Plane in Children

“…It is extremely necessary to create an image of children's body posture at a very early stage that contributes to overall growth and development and quality of life. In order to determine the condition of the body posture, it is necessary to use screening tests, which play an important role in the quick and reliable assessment of the proper development of children and adolescents [13]. Good posture is one of the basic requirements for good health, normal growth, and development as a whole [14].…”
