Glossary Term

Distraction

Distraction (traction): Distraction is an arthrokinematic motion. A force applied that separates two surfaces; that is, a force that increases the space or decreases the pressure between two surfaces. Similar to the way a suction cup is pulled from a window. An anatomical example would include forces that pull one bone surface apart from another, increasing intra-articular volume.

An anatomical example would include forces that pull one bone surface apart from another, increasing intra-articular volume. For example, hanging from one's hands (e.g. in preparation for a pull-up) results in a traction force on the glenohumeral joint (shoulder).
