Comparison of Two Handheld Digital Dual Inclinometry Techniques in the Measurement of Lumbar Flexion Active Range of Motion.

Context: An accurate assessment of lumbar spine active range of motion (AROM) is clinically important. Dual inclinometry is recommended as the optimal technique for measuring lumbar flexion AROM; however, the procedures differ in the literature.

Objective: To compare 2 different handheld digital dual inclinometry (HDDI) techniques for evaluating lumbar flexion AROM.
