Thoracic rotation measurement techniques: clinical commentary.

Abstract

A number of sporting and daily activities involve rotation of the spine. The ability to quantify motion of the spine in a clinical setting usually relies on the use of a device to measure angles (goniometer or inclinometer) or visual assessment. Standardized measurement criteria exist for measuring rotation at the cervical and lumbar spine. Little has been written regarding established methods for measuring thoracic spine rotation. Thoracic rotation may be measured in a seated position, half-kneeling position, or quadruped position. Steps should be taken to minimize motion of surrounding segments such as the shoulder and hips, which may improve measurement accuracy. Key words: inclinometer, goniometer, range of motion.
