Which statement about stabilization during gravity-minimized wrist extension testing is true?

• A. The Clinician Stabilizes the Forearm Against the Table Top
• B. The Elbow Is Stabilized by a Strap
• C. Gravity Provides Stabilization
• D. There Is No Stabilization

Answer: (A)

In gravity-minimized testing, the goal is to isolate the movement to the targeted joint by preventing nearby segments from moving. For wrist extension, stabilizing the forearm against the table keeps the radius and ulna from shifting, and stops movements at the elbow or shoulder from contributing to the motion. This lets the wrist extensor muscles be evaluated or resisted specifically, without leverage from the forearm or other joints. Gravity isn’t relied on for stabilization in this setup, and a strap on the elbow isn’t the standard stabilization method here. There is stabilization, unlike option indicating no stabilization.
