Abduction vs. Adduction of the Fingers, Clinical Tests and an Easy Way to Remember

The video tutorial covers the concepts of finger abduction and adduction, explaining the muscle groups responsible for these movements: the dorsal interossei for abduction and the palmar interossei for adduction. A mnemonic, DABPAD, is introduced to help remember these muscle groups. The tutorial also demonstrates clinical tests to assess the strength of these muscles and the function of the ulnar nerve, which supplies them. The video concludes with a summary of the tests and a call to action for viewers to like and subscribe.

Describe the clinical test used to assess the strength of the dorsal interossei muscles.

How do both abduction and adduction tests assess ulnar nerve function?
