I am little bit confused about direction of rolling. I thought if it is extension shoulder moves posteriorly and roll should be anteriorly?

[@randMcnally16]

i love your channel but correct me if i am wrong, in a convex on concave rule the distal segment moves in opposite direction from the proximal segment so wouldn't the roll be in the opposite direction of the osteokinematic movement? shoulder extension = anterior roll of the glenohumeral joint?

[@CatalystUniversity]

Thank you, Randy. The roll is always in the same direction as the joint movement. The slide (or glide, sometimes it's called) is what you have to figure out - opposite or same. So for shoulder flexion, roll is anterior. For shoulder extension, roll is posterior. Then for open-chain glenohumeral movement, slide (glide) is opposite of roll.

[@agataryska2516]

In flexion and extension is not te movement of the head of the humerus a spin movement towards the glenoid?
