  • Have the client seated
  • Partially flex forearm and have the forearm half way between pronation and supination.
  • Place palpating hand on the proximal anterior medial forearm
  • Have the client further flex or pronate the forearm and feel for contraction of the pronator teres
  • The proximal attachment is the medial epicondyle of the humerus and the distal attachment is the lateral radius underneath the brachioradialis

84.

  • Client seated
  • Place palpating hand across anterior wrist
  • Have client actively flex and radially deviate the hand at the wrist joint and feel for the distal tendon on the radial side just lateral to the palmaris longus
  • Palpate proximally toward the medial epicondyle
  • It is difficult to palpate the proximal tendon because it blends with the common flexor tendon of the elbow

85.

  • Have client seated
  • Place palpating hand on anterior wrist
  • Ask the client to cup the hand (bring thenar and hypothenar eminence together)
  • Ask client to flex the hand at thewrist joint against resistance with the fingers fully extended; feel for the distal tendon of the palmaris longus in the center of the wrist.
  • Palpate proximally to the common flexor tendon of the elbow

86.

  • Have client seated
  • Place palpating hand across anterior wrist
  • Have client actively flex and ulnar deviate the hand at the wrist joint and feel for the distal tendon on the medial side of the anterior wrist.
  • Palpate proximally toward the medial epicondyle and the common flexor tendon of the elbow.

87.

  • Have client seated with forearm flexed at the elbow 90 degrees, and in a position halfway between pronation and supination.
