Study Notes
Finger Motion and Tests
- Major substitution for flexor digitorum superficialis motion is flexor digitorum profundus.
- In the DIP test, Grade 3 instructs the patient to actively flex the DIP joint.
- In Grade 1 of the DIP test, the forearm is in a neutral position.
- Extensor digitorum communis and extensor indicis proprius are prime movers for FINGER MP EXTENSION ROM.
- A 'tenodesis' action in the context of finger motion refers to the flexion of the fingers when the wrist is extended.
- Flexor digitorum profundus and flexor digitorum superficialis are prime movers for finger MP flexion.
- The range of motion (ROM) for finger PIP flexion is 100-110 degrees.
- Intrinsic muscles (interossei and lumbricales) may substitute for the lumbricales during finger MP flexion.
- A grade of 5 is given when a patient completes full range of motion in a gravity-eliminated position for finger flexion.
- In the PIP test, the patient is instructed to actively flex the PIP joint while the examiner resists the movement.
