Reliability of “MB-Ruler Software” to Measure Craniovertebral Angle Using the Photographic Method

Abstract Background The craniovertebral angle (CV angle) measurement is a convenient and easy clinical method for the cervical posture assessment. “Markus Bader (MB) ruler software” assists to measure angles distances on computer screen. MB-ruler protractor almost transparent; hence, it can be easily used Many studies in physiotherapy have this software postural assessment with photographic method, but reliability of not available our knowledge Indian population. Aim aim study was find inter-rater intra-rater reliabilities “MB-Ruler software”, by using CV Study Design This an observational healthy young Subjects Method Total 30 student volunteers no symptoms were enrolled study. A single standard lateral view image sitting position “MB software.” Three readings taken three different observers (A, B, C) separately at intervals time. measured compared. Results Cronbach's ɑ coefficient value (ICC 0.999) (intra-class correlation coefficient) as well 0.892) measuring very high. Conclusion MB demonstrates high evaluation assessing angle.
