supination

 [soo″pĭ-na´shun]
the act of assuming the supine position; placing or lying on the back. Applied to the hand, the act of turning the palm upward.

su·pi·na·tion

(sū'pi-nā'shŭn), [TA]
1. The condition of being supine; the act of assuming or of being placed in a supine position; rotation of the forearm such that the palm of the hand faces anteriorly to the anatomic position; rotation of the foot such that the plantar surface of rotated upward.
2. The opposite of pronation.

supination

/su·pi·na·tion/ (soo″pĭ-na´shun) [L. supinatio ] the act of assuming the supine position, or the state of being supine. Applied to the hand, the act of turning the palm forward (anteriorly) or upward, performed by lateral rotation of the forearm. Applied to the foot, it generally implies movements resulting in raising of the medial margin of the foot, hence of the longitudinal arch.

supination

[so̅o̅′pinā′shən]
Etymology: L, supinus, lying on the back
1 one of the kinds of rotation allowed by certain skeletal joints, such as the elbow and the wrist joints, which permit the palm of the hand to turn up.
2 assumption of a supine position, one of lying on the back, face up. Compare pronation. supinate, v.

su·pi·na·tion

(sū'pi-nā'shŭn) [TA]
1. The condition of being supine; the act of assuming or of being placed in a supine position.
2. Transverse plane motion at the radioulnar joint or transverse tarsal joint.

supination

The act of turning the body to a SUPINE position or of turning the horizontal forearm so that the palm of the hand faces upward. Compare PRONATION.

supination

(1) of the foot: during normal gait immediately before 'take-off' from the toes, the ankle tends to angle outwards and the foot is supported briefly on its outer side. oversupination can cause the ankle to roll over towards the outer side, with possible ligament damage; (2) of the forearm: twisting movement which brings the palm of the hand to face upwards or forwards. See also pronation.

supination

moving into a supine position

supination

triplanar foot movement; forefoot adduction and plantarflexes + ankle plantarflexion + subtalar joint internal rotation (inversions); directs entire plantar surface towards sagittal plane of the body (Figure 1) (contrast with pronation)
