Q

List the 2 taught hand points and describe their location

A
  1. LI4

At the level of the midpoint of the second metacarpal, between the first and second metacarpal on the dorsum of the hand. Feel for a depression and a tender spot.

  1. HT7

On the wrist crease (palmar aspect) located between the ulnar styloid process and the pisiform bone, lateral to (on the radial side) of the flexor carpi ulnaris tendon.
