Common distortions due to tightness is a median and ulnar nerve entrapment. It is important to
assess these muscles, along with other soft tissues in the forearm and wrist, with carpal tunnel
syndrome.


PRONATOR TERES


Joint Action performed by the Forearm



  1. Secondary pronator

  2. Flexes


For example it turns the palm of the hand downward

Origin: 1. Humerus – Medial epicondyle



  1. Ulna – Coronoid process


Insertion: Radius (midway along lateral aspect)


Common distortions due to tightness is a median nerve entrapment mimicking or contributing
to carpal tunnel syndrome


PRONATOR QuADRATuS


Joint Action performed by the Forearm



  1. Primary pronator


For example it helps to turn the palm down

Origin: Ulna – Anterior aspect of distal quarter


Insertion: Radius - Anterior aspect of distal quarter


Common distortions due to tightness is a lateral epicondylosis caused by overloading
of the supinator
