From: Ultrasonographic median nerve cross-section areas measured by 8-point "inching test" for idiopathic carpal tunnel syndrome: a correlation of nerve conduction study severity and duration of clinical symptoms

Figure 1

The 8-point for recording in both "inching test" and ultrasonography. The i4, i3, i2, i1 represent levels at 4, 3, 2, and 1 cm distal to the wrist crease in the inlet of the carpal tunnel; w represents the level of the wrist crease and o1, o2, and o3 represent levels at 1, 2, and 3 cm proximal to the wrist crease in the outlet of the carpal tunnel.
