Circumduction is moving a limb slowly in a circle to visit the whole range.
In 📝Articular Mobility it is a small, slow orbit inside the range the joint already has, not a windmill and not a thrust at the bottom of the circle. The circle maps comfort in every direction. Pinch, catch, or brace in one quadrant is information, not a cue to push that corner.
Clients feel a slow tour. Dizziness or a catch that does not ease is a stop.
