During MMT wrist flexion in anti-gravity, which statement about stabilization is correct?

• A. The patient stabilizes the forearm.
• B. The clinician stabilizes the forearm.
• C. Stabilization is provided by the table.
• D. No stabilization is used.

Answer: (B)

When testing a wrist flexor muscle against gravity, you must isolate the wrist motion from the rest of the arm. The forearm is the proximal segment being stabilized, so any movement at the elbow or shoulder could create apparent wrist flexion and mask the true strength of the wrist flexors. The clinician provides that stabilization by holding the forearm steady during the test, preventing substitutions from the elbow or shoulder and keeping the motion confined to the wrist. The table may support the forearm, but it does not actively stabilize against the testing movement the way the clinician does. No stabilization would allow compensatory movements, making the measurement unreliable.
