Projection moiré as a modern tool for diagnosis of body posture
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2012, Vol 22, Issue 60
Abstract
Diagnosis of body posture should be based on a set of strict criteria typical of a particular method. Each method is subject to an error which results from temporal and unequivocal individual values. Taking measurements of a particular characteristic should be based on an assumption that the measurement will differ from its value during the second measurement. Assuming the reliability and validity of a method used for body posture diagnosis, the difference results from errors and accuracy of measurements, lack of standard conditions and the patient’s posture which is continuously adapting to the stressors present in the external and internal environment human body is exposed to. The end of the 20th century saw dynamic progress in technical sciences. This allowed for utilization of electronics for measuring spinal curvatures. After solving a variety of problems of technical and methodological nature, the assessment of body posture was rested on the phenomenon of projection moiré discovered in 1935. This study discusses the advantages and drawbacks of this method. The normative ranges developed by Iwanowski, Łubkowska, Mrozkowiak, Nowotny, Wolański, Zeyland-Malawka i Żołyński were also presented. The authors of the present study determined angles of thoracic kyphosis and lumbar lordosis and the types of body posture according to Wolański.
