Min F latency, ms	26.38 ± 1.56	26.96 ± 1.61	25.63 ± 1.74*	27.08 ± 1.57	0.711	0.008

SP Duration, ms	182 ± 13.8	182 ± 11.6	188 ± 12.9	189 ± 17.6	0.262	0.907

Values are means ± SD. Overall RM ANOVA results illustrate Group effects (across HS and TN conditions) and Treatment effects (across groups). Post hoc within-group differences between conditions are indicated. CMAP, compound muscle action potential; Min F, minimum F-wave latency of 20 trials; NCV, nerve conduction velocity; SP, cortical silent period; RMT, resting motor threshold.

^*Significant within-group difference from TN condition, determined by post hoc analysis.
