by Judy C. Colditz, OT/L, CHT, FAOTA 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.
In-depth 4.5 hour lecture on what muscles drive finger movement
52 video segments demonstrating movement on a fresh cadaver or clinical examination/movement of the hand
More than 300 custom illustrations, photos and schematic drawings produced especially for this video
110 interactive self-study questions with scoring feedback

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.
