To achieve maximum compression of structures in the carpal tunnel, how should the client position their wrist?

To achieve maximum compression of structures in the carpal tunnel, positioning the wrist in a flexed position is effective because this alignment narrows the space within the tunnel. The carpal tunnel is formed by the carpal bones on the bottom and the transverse carpal ligament on the top. When the wrist is flexed, the tension on the ligament increases, effectively reducing the space for the median nerve and other structures within the tunnel.

This increased compression can help simulate conditions like carpal tunnel syndrome and allows practitioners to understand better the impact of wrist positions on nerve and muscle functionality. Flexion alters the anatomy and biomechanics of the wrist, influencing how structures within the carpal tunnel interact and potentially leading to greater insight into treatment and diagnosis related to wrist pain or dysfunction.

In contrast, a neutral position maintains the anatomical alignment with minimal compression, while fully extending or radially deviating the wrist could create more space within the tunnel, which is contrary to the goal of compressing these structures.
