Early-Stage Diabetic Neuropathy Reduces Foot Strength and Intrinsic but Not Extrinsic Foot Muscle Size

Figure 4

Example comparison of muscle size between DPN (left) and CON (right) subjects. The top row is a comparison of the size of the AH. The bottom row is a comparison of QP and FDB muscles, with FDB being shown above the QP. Values of the circumference (C) and cross-sectional area (A) of the muscles can be seen in the bottom left of each image. (Note that images were only approximately scaled; see numbers in the bottom left corner for area comparisons).

(a) AH-DPN

(b) AH-CON

(c) FDB and QP-DPN

(d) FDB and QP-CON
