Manual Muscle Testing: Elbow Extension
Prone with test side shoulder in ~90 degrees abduction
Patient's test side forearm is hanging over side of plinth; upper arm supported on plinth to elbow.
For grades 0-2, the gravity minimal position is supported sitting with feet flat on the floor. The shoulder remains in the same position.
At test side
Provide stabilization support just above elbow
- Patient is to extend elbow to full available range
- Grades 4 and 5 - The therapist will apply resistance over the dorsal forearm in the direction opposite to extension
- To satisfy grade 5 'normal muscle' performance criteria, the patient must have the ability to move through complete range of motion (active resistance testing) OR maintain an end point range (break testing) against maximum resistance.
