If the armrest height is too high, which is a consequence?

Explanation:
When the armrest is too high, the body compensates by lifting the shoulder girdle to keep the forearm supported at that height. This causes the scapula to elevate, driven by upward pull from muscles like the upper trapezius and levator scapulae. With the scapula in an elevated position, full scapular depression and stable scapulohumeral rhythm become harder to maintain, which can lead to neck and shoulder tension over time. If the armrest were too low, you’d more likely see scapular depression, not elevation. An armrest that’s too high also doesn’t improve propulsion or reach to drive rims; it typically hinders comfortable, efficient movement.
