Use of Noninvasive Techniques for Quantification of Spinal Range-of-Motion in Normal Subjects and Chronic Low-Back Dysfunction Patients

Abstract

Quantitative measures of physical function (range of motion, strength, stability) are critical to musculoskeletal care of the extremities, yet such objective measures in the spine are currently unavailable. In this paper, the authors present a simple, single inclinometer modification of the method of Loebl, which offers the opportunity to separate the components of the compound motion of hip and spine. Analysis of the motion in normal and chronic low-back pain patients allows differentiation of the groups, demonstration of progress in rehabilitation programs, determination of impairment, and provides tests of patient compliance and level of motivation.
