However, shoes made for supinators
, who excessively roll their foot outward during midstance, should emphasize shock-absorption over motion control in order to cushion the lateral (outside) edge of the foot.
It bifurcates at the level of the elbow joint into the superficial nerve, which courses dorsally under the extensor carpi radialis brevis, and the PIN, which dives under the superficial head of the supinator muscle and continues along with the posterior interosseous artery to supply all of deeper lying extensor muscles.
A second arm of the study likewise included cadaveric dissection that revealed the button was separated from the radial nerve by a layer of supinator muscle superficial to the button and deep to the nerve.
It is speculated that the short head is positioned in such a way that it acts as a more powerful elbow flexor, while the long head acts as a more powerful supinator
14) The biceps is both a strong flexor and supinator
of the elbow.
The PIN runs around the posterolateral radial neck before it enters the supinator
It originates at the lateral epicondyle with the radial collateral ligament and inserts at the supinator
crest of the ulna.
Over time, supinators
stress the outside of their feet and ankles, which can lead to sprains, tendinitis, and stress fractures.
It provided cushioning suitable for supinators
and normal feet.
Hypertonia was measured in nine muscle groups (shoulder internal rotators, elbow extensors, elbow flexors, pronators, supinators
, wrist flexors, wrist extensors, digit flexors, digit extensors) with the Modified Ashworth Scale [23-24].
, wrist flexors/extensors, and finger flexors/extensors), for which scores range from 0 to 5, with a score of 0 for a subject with no movement or excitation and a score of 5 for a subject able to hold a position against test-applied resistance.
The modified Ashworth scale scores for individual joints were grouped into a proximal score (maximum [max] = 15: shoulder internal rotators, elbow extensors, elbow flexors), and a distal score (max = 30: pronators, supinators
, wrist flexors, wrist extensors, digit flexors, digit extensors).
