Abstract
The measurement of the flexion range of motion of the lumbar spine is a common practice in clinical settings. Many methods are used to carry out these measurements, such as the Back Range of Motion Inclinometer (BROMII ) and the Flexible Ruler methods. Objective and methods: The aim of this study was to analyze the interexaminer reliability for the measurement of the lumbar spine flexion by using the BROMII and the Flexible Ruler methods. Thirty-seven physical therapy students were recruited as volunteers and a double-blind test-retest study design was carried out. Results: The results showed moderate reliability of the BROMII measurements [ICC (2.1) 0.71 (95%CI 0.49-0.84) p<0.000]; however, the reliability of the Flexible Ruler measurements was poor [ICC(2.1) 0.37 (95%CI 0.06-0.62), p<0.012]. Conclusion: The BROM II presented sufficient reliability to be performed in clinical practice.
