Where is the L4 dermatome?
Medial leg to behind the ankle and into the arch of the foot to the medial aspect of the big toe
37
How is a muscle test for tibialis anterior for an L4 MRS performed?
Placement of the foot is up and in and the doctor pulls foot down and out
38
How is a muscle test for the quadriceps for an L4 MRS performed?

41
What reflex is tested first for an L5 MRS?
Medial hamstring tendon
42
How is an extensor digitorum test for an L5 MRS performed?
Place toes into extension and have doctor push toes down
43
How is an abductor muscle group test for an L5 MRS performed?
Patient is side-lying, doctor presses top leg into adduction stabilizing above the iliac crest
44
What is the secondary muscle test for the L4 MRS?
Quadriceps
45
What is the action of the quadriceps?
Hip flexion and knee extension
