When testing motor function as part of PMS, which statement best describes how to test?

• A. Test motor skills in all four extremities with active movements by the patient, including wrist/finger extension and flexion, and foot plantar and dorsiflexion
• B. Test motor skills with passive movements only
• C. Test motor skills in only one limb
• D. Do not test motor skills

Answer: (A)

Testing motor function in PMS relies on having the patient actively move their joints to judge strength and nerve/muscle function. By asking the patient to perform movements with all four extremities, you can compare sides and detect weakness or paralysis that indicates a neurovascular issue. Active movements—like wrist and finger extension and flexion, and ankle plantar and dorsiflexion—test the major muscle groups and their nerve pathways, giving a true read on motor integrity. Passive movements don’t require the patient to activate muscles, so they can miss weakness or nerve injury even when the limb isn’t functioning properly. Testing only one limb could miss problems in the other limbs, and not testing motor at all leaves you without crucial information about limb function.
