In radiocarpal volar glide joint mobilization, where is the stabilizing hand placed?

• A. On the proximal forearm
• B. At the distal forearm just proximal to the radiocarpal joint line
• C. On the distal humerus
• D. On the palm of the hand

Answer: (B)

In radiocarpal volar glide, the stabilizing hand should anchor the forearm so the movement is isolated to the radiocarpal joint. Placing the stabilizing hand on the distal forearm just proximal to the radiocarpal joint line fixes the radius/forearm, while the other hand moves the carpal bones anteriorly. This position prevents unwanted motion of the proximal segment and allows a clean volar glide of the carpal row relative to the radius. Placing the stabilizing hand on the proximal forearm, the palm, or the distal humerus would either fail to control the proper segment or engage a different joint, making the mobilization ineffective or unsafe.
