During MMT wrist extension in anti-gravity, which describes the direction of resistance?

• A. Upward to the Palm of the Hand
• B. Downward to the Dorsum of the Hand
• C. Horizontal Lateral
• D. Diagonal to the Radial Side

Answer: (B)

The ability to test wrist extensors in anti-gravity hinges on applying resistance in the opposite direction of the movement. When the wrist extends, the movement is wrist dorsiflexion (the back of the hand moves upward). To challenge these extensors, you press on the dorsum (back) of the hand and direct the force downward toward the palm, resisting the extension. This forces the extensor muscles to generate force to maintain the position against the resistance. Pushing upward on the palm would not oppose the motion, and directions like horizontal or diagonal would either test different motions or deviate from pure wrist extension, so they don’t isolate the wrist extensors as effectively.
