What is the most appropriate joint mobilization technique for a patient with wrist extension limitations post-surgery?

• A. Grade I mobilization of the distal carpal row
• B. Grade II mobilization of the radioulnar joint
• C. Grade IV mobilization of the proximal carpal row
• D. Grade III mobilization of the metacarpophalangeal joint

Answer: (C)

In the context of addressing wrist extension limitations following surgery, selecting the proper joint mobilization technique is crucial for promoting flexibility and restoring function. The emphasis on the proximal carpal row reflects an understanding of the anatomy and biomechanics involved in wrist movement.

The wrist consists of multiple joints, with the proximal carpal row, including the scaphoid, lunate, and triquetrum, playing a significant role in wrist extension. Grade IV mobilization, characterized by a high-velocity, low-amplitude thrust, is designed to increase accessory motion and improve the overall joint mechanics. This technique is typically effective in helping to restore full range of motion after surgical interventions, especially when stiffness results from scar tissue or other adhesions that may have formed postoperatively.

Utilizing this mobilization technique specifically targets the area where restrictions are most likely to occur, thereby helping to promote recovery and enhance the quality of motion in wrist extension. Additionally, the other joint mobilization options, while beneficial in other contexts, do not directly address the primary limitation of wrist extension. Grade I and II are typically used for pain relief or maintaining movement in the absence of extensive restrictions, while Grade III is more geared toward improving mobility at joints other than the primary focus of extension.
