Figure 6

Images taken from a single strain measurement trial and a schematic of the system. Image definitions are as follows: (A) no cuff present, relaxed position; (B) no cuff present, extended position; (C) cuff present, relaxed position; (D) cuff present, extended position. Double headed arrow shows rotation of the nerve seen through the marker position (left side in (B), left to center in (C)). Brackets highlight differences in the impact of nerve contact with the cuff, and dotted lines highlight the cuff-nerve interface. (C) shows increased compression not present in (D). The line on the right of the nerve in (C) and (D) show alteration of the natural nerve path. (E) shows a schematic of the nerve movements seen in images (C) and (D).
