Abstract

For spinal flexibility measurements to be meaningful to clinicians or researchers, they musthave a normative information and an understanding of how different variables affect spinalrange of motion (ROM). Normal spinal ROM measurements are influenced to differing degreesby many factors. These factors include age, gender, time of day, leisure activities, previoushistory of low back pain, warming up, and the techniques with which normative data are collected. The additional variables of standing height, ratio of standing height to sitting height, andobesity had not been previously studied extensively and were shown to have a significanteffect on flexibility in the sagittal plane. These relationship cannot be explained easily. Thus, the purpose of this study was to determine the relationship between spinal flexibilityand individual factors (weight, standing height, and ratio of standing height to sitting height)that influence it. Fifteen healthy subjects between the ages of 20 and 27 years were studied. Two physical therapists measured independently the spinal forward bending ROM in the sagittalplane by Remodified Schober test and Finger-to-floor test. In order to determine the statisticalsignificance of the result the Pearson's correlation was applied at the .05 level of significance. The results of this study were as follows: 1) Significant relationship was not identified betweenspinal flexibility and weight. 2) Significant relationship was not identified between spinalflexibility and standing height. 3) Significant relationship was not identified between spinalflexibility and ratio of standing height to sitting height.
