ABSTRACT
Every articulating joint of the body has a normal range of motion. Working with the body positioned in a neutral posture means that no parts of the body are bent, twisted, or otherwise contorted away from a normal, relaxed, and comfortable position. For specific body segments, this means that a neutral posture conforms to the following guidelines (note that these positions are not absolute and a task may require intermittent excursions beyond them, but sustained postures outside of the neutral posture can cause discomfort and injuries):
• Neck-The neck is balanced and aligned with the top of the spine with minimal forward flexion or backward extension (dorsiflexion), and not laterally bent or twisted.
