Intertester Reliability Using The Cybex Edi 320® Inclinometer, Schawnn M. Decker

Physical Therapy Scholarly Projects

The American Medical Association (AMA) currently accepts range of motion measurements, particularly spinal measurements obtained by an inclinometer, as reliable and accurate. Reproducibility of intra-subject results are considered high, but intertester reliability has not been addressed.

With the help of three physical therapists trained in the use of the Cybex EDI 320® inclinometer, 10 subjects were tested on three consecutive days by each tester to obtain measurements of lumbar flexion, corresponding hip flexion, lumbar extension, corresponding hip extension, and lateral flexion. Straight leg raise measurements were also obtained for validity measurements as requested by the AMA.
