Preserved capacity to detect low-force monofilaments following preferential block of myelinated fibres. Monofilament detection thresholds (mN) were measured in the ulnar territory of the glabrous (finger and palm) and hairy skin of the hand prior to, and following, conduction blockade of myelinated fibres. Threshold data are shown for each subject (S1S7) with an arrow linking the intact and compression values. In all subjects, the capacity to detect weak monofilament contacts was preserved in hairy and glabrous regions despite the blockade of myelinated fibres. In fact, with the exception of one subject (S5), all of them could reliably detect contact forces below 6 mN in both skin types, and in three of them (S1, S3 and S6) the post-compression threshold was below 2 mN in the glabrous region
