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

[@agataryska2516]

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

[@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?

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.
