Supination
movement that turns the palm up
Supination is a movement of the foot or hand that involves turning the sole of the foot or the palm of the hand upward or outward.
In the foot, supination is a combination of three movements – inversion, plantarflexion, and adduction. This movement involves the foot rolling outward, resulting in weight being placed on the outside edge of the foot as the heel lifts off the ground. This movement is important for shock absorption during activities such as running and jumping.
In the hand, supination involves the rotation of the forearm and the outward rotation of the hand and wrist. This is important for tasks such as turning a doorknob, throwing a ball, or reaching for an object.
Supination is important for proper joint function and stability, and deficits in supination can result in injuries or problems such as ankle sprains, plantar fasciitis, and tennis elbow. Therefore, it is important to include exercises that promote supination in rehabilitation and strength training programs. Examples of exercises that promote supination include calf raises, heel walks, and wrist curls.
