High-Frequency Transcutaneous Peripheral Nerve Stimulation Induces a Higher Increase of Heat Pain Threshold in the Cutaneous Area of the Stimulated Nerve When Confronted to the Neighbouring Areas

Table 1

Statistical significance of differences in heat pain thresholds recorded during and after the electrical stimulation when confronted to the basal values (post hoc test included).

	Session 1, radial nerve stimulation radial territory recording	Session 2, radial nerve stimulation ulnar territory recording	Session 3, no stimulation radial territory recording
𝑇1 versus 𝑇0	𝑃 = 0.001	NS	NS
𝑇2 versus 𝑇0	𝑃 < 0.001	NS	NS
𝑇3 versus 𝑇0	𝑃 < 0.001	NS	NS
𝑇4 versus 𝑇0	𝑃 = 0.008	NS	NS
𝑇5 versus 𝑇0	NS	NS	NS
𝑇6 versus 𝑇0	NS	NS	NS
Post hoc test
	Session 1 versus Session 3	Session 1 versus Session 2	Session 2 versus session 3
