What is the wrist position described for gravity-minimized wrist extension testing?

• A. Wrist in Neutral
• B. Wrist Extended
• C. Wrist Flexed
• D. Wrist Deviated

Answer: (A)

Gravity-minimized testing aims to remove the influence of gravity so the true strength of the muscle can be observed. For wrist extension, placing the wrist in neutral with the forearm supported eliminates the gravitational torque that could either help or hinder the movement, giving a cleaner measure of the wrist extensor strength. If the wrist were extended or flexed, gravity would introduce additional torque that would confound the assessment; deviation from neutral would involve other muscle groups and joint motions, further biasing the result. So the neutral position is used to minimize gravity’s effects and isolate the test.
