ABSTRACT

Introduction: Posture analysis software Matlab 7.11 R2010b is commonly used as a tool for postural assessment. It is easy to use. Nonetheless, reliability studies are lacking.

Methods: The study sample consisted of 25 pictures from 25 subjects, and each subject was assessed (1 day interval) by 3 blinded raters and by 1 blind rater for 3 times. Photographs of subject were coded and two variables (Lumbar lordosis and Pelvic tilt) were analyzed. Inter- and intra-rater reliabilities were calculated using intra-class correlation coefficient.

Results: The intra-class correlation coefficient (ICC) was calculated. We found excellent inter-rater reliability and intra-rater reliability of Posture analysis software Matlab7.11 R2010b for both variables.

Discussion: Observation posture analysis is easy but it is less reliable method. It cannot be used to measure progression of posture corrections and for research purpose. Photography method is most reliable method to evaluate posture. There are many softwares available for analysis of posture and Matlab 7.11 R2010b is one of them. In this study we found excellent inter-rater reliability and intra-rater reliability of the software.

Conclusion: The postural assessment software Matlab 7.11 R2010b is having excellent inter-rater reliability and intra-rater reliability and should be considered as a reliable tool for postural assessment.

KEYWORDS: Matlab, Posture, Reliability, Lumbar lordosis, Pelvic Tilt.
