Standing, sitting or lying supine
Anterior to the patient.
May I touch your hand? ( or point to the demonstrated area ).
Please bend your elbow and turn your palm up. Bring your little finger toward your body (or demonstrate, which is easier). (If needed, hold in this position while I try to move your little finger.)
This muscle may be referred to as the abductor digiti quinti or the abductor digiti minimi.
Guide the patient to bend the elbow and supinate. With the muscle relaxed, palpate the medial side of the little finger and guide the patient to abduct the metacarpophalangeal joint of the little finger. To palpate the tendon, move your finger to the proximomedial aspect of the proximal phalanx of the little finger and perform the same motion. The tendon of this muscle joins the tendon of the flexor digiti quinti. With unclear muscle activity, provide added resistance by having the patient ìholdî while you gradually produce a push on the proximal phalanx of the little finger in the direction of adduction.
Both the flexor carpi ulnaris and the abductor digiti quinti attach to the pisiform bone. When the abductor digiti quinti is activated to move the little finger, the flexor carpi ulnaris is activated to stabilize the proximal attachment of the abductor digiti quinti.

TAKEN OUT:
Observe the technique of the palpation in one video. In the other video, observe the activation of the flexor carpi
ulnaris during activation of the abductor digiti quinti muscle.
