Mechanical latency of sensory fibres following nerve injury. Latencies of RAM and SAM (Aβ), D-hair and AM (Aδ), and C fibres to nanomotor stimulation were not significantly altered by nerve injury (P > 0.05; 2-way RM ANOVA) (A-E). In uninjured nerves, the number of fibres from sham-operated and nonoperated nerves is as follows: RAM (4 and 14), SAM (12 and 11), D-hair (4 and 7), AM (8 and 18), and C fibres (4 and 7). Data are expressed as means ± SEM. N, number of fibres.
