Standing, sitting or lying supine
Anterior or medial to the patient.
May I touch your forearm? ( or point to the demonstrated area ).
Please turn your palm up and then bring your hand up and in toward your body
(or demonstrate, which is much easier). (If needed, hold in this position while I try to move
your hand.)
Guide the patient to supinate. With the patient relaxed, place the fingers on the medial and
slightly anterior aspect of the forearm, where the muscle belly is located. Guide the patient
to ulnarly deviate and flex the wrist. Palpate the muscle on the medial forearm during this combined and diagonal motion. This palpation is not demonstrated on the video. With unclear muscle activity, provide gradually increasing resistance by having the
patient ìholdî while you produce a push on the hand in the diagonal direction of wrist
extension and radial deviation.
With the patient relaxed, place the fingers on the tendon located at the distal medial forearm, just proximal to the pisiform bone. Follow the same procedure and palpate the tendon.
Note that the flexor carpi ulnaris and the abductor digiti minimi both attach to the pisiform bone. Contraction of each muscle pulls the pisiform toward that muscle.
