Complex made simple: comprehensive analysis of how the muscles and tendons actively move the finger.
This DVD/CD self-study module presents an extensive look at what part of the finger is activated to achieve finger movement. This is a concentrated review of how the complex anatomy drives digital motion. This module, the second in our series on Digital Dynamics, concentrates on motion of the normal finger.

Learning Outcomes/Course Objectives 
Upon review of the video, completion of the self-study exercises, and review of the self-study questions, the learner will be able to:
-
Describe primary and secondary (if any) function of the anatomical components of the dorsal apparatus of the finger.
-
List the retinacular structures of the wrist and fingers and identify the role of the retinacular structures of the finger.
-
Explain three different examples of the interdependent motion between the PIP and DIP finger joints.
-
List the four insertions of the dorsal apparatus.
-
Explain the difference of strength in MP extension at neutral versus hyperextension.
-
Explain Bouvier’s maneuver.
-
Explain the function of the EDC during normal finger flexion.
-
Demonstrate the position of manual muscle testing for normal and weak EDC.
-
Indentify the fibers through which the interosseous muscles achieve MP joint flexion and PIP joint extension.
-
Describe how the position of the MP joint determines which interosseous muscle fibers are active.
-
Identify three finger motions contributed to by the interosseous muscles.
-
Describe the role of the interosseous muscles at the beginning of finger flexion from a position of full finger extension and at the end of finger flexion with power grip.
-
Demonstrate the difference in strength between finger adduction and abduction.
-
Demonstrate interosseous muscle pull at the end range of finger flexion.
-
Describe position 1 and position 2 of the interosseous muscle tightness test, identifying exactly what joints are included and the precise position of each joint in each position.
-
Describe how to manually muscle test the interosseous muscles.
-
Choose the position of maximum length and minimum length of the interosseous muscles.
-
Describe the role of the lumbrical muscle at all three finger joints.
-
Explain how the lumbrical muscle moves the finger.
-
Explain why one cannot manually muscle test the lumbrical muscle.
-
State the primary and secondary role of the lumbrical muscle in finger movement.
-
Describe the positions of the longest length of the lumbrical muscle.
-
Clarify the mechanics of a lumbrical-plus finger and how can it be treated.
-
Describe the lumbrical muscle tightness test and the result of a positive test.
-
Clarify the testing and stretching positions of the lumbrical muscle.
-
List seven differences between the lumbrical and interosseous muscles.
