Arthrokinematics

Arthrokinematic Motion - Small amplitude motions between bone surfaces at a joint.  The arthrokinematic motions are roll, glide (slide or translation), spin, compression and distraction (traction). Arthrokinematic motions accompany osteokinematic motions to maintain joint congruence.

• Example, arthrokinematic motion of the talus includes posterior glide on the tibia during ankle dorsiflexion.

Synonyms include: arthrokinematics, passive accessory motion, joint play and component motion
