Hand works as a foot

... and wrist as an ankle.

Although the hand and foot are located at opposite ends of the body, their functions involve similar mechanics.

Just as the ankle moves through dorsiflexion and plantar flexion, causing the foot to shift into supination or pronation, similar movements also occur in the upper limb.

When the knee moves past the toes, the tibia must internally rotate. If the tibia’s rotation is limited, the knee’s forward movement becomes restricted, sometimes resulting in a pinching or blockage sensation at the front of the ankle.

A similar rotation occurs in the radius when, for example, placing the hands in a push-up position. If the radius lacks the ability to rotate inward relative to the hand, discomfort in the wrist, similar to that of the ankle, can occur.
