Do Tonic Itch and Pain Stimuli Draw Attention towards Their Location?

Table 2

Means ± standard deviations of NRS itch, pain, and unpleasantness scores at baseline and during the pain, itch and control blocks of the somatosensory attention task (SAT) .

	NRS itch	NRS pain	NRS unpleasantness
Baseline itch stimulus	3.5 ± 2.2	0.6 ± 1.1	2.3 ± 2.0
Baseline pain stimulus	0.9 ± 1.3	3.9 ± 1.7	3.4 ± 1.8
SAT itch blocks	1.8 ± 1.6	0.2 ± 0.4	1.2 ± 1.5
SAT pain blocks	0.5 ± 0.8	3.0 ± 1.7	2.7 ± 1.7
SAT control blocks	0.1 ± 0.2	0.0 ± 0.1	0.0 ± 0.1

Note. The electrical current at which the itch and pain stimuli were applied was tailored to individual sensitivity and was identical during baseline measurements and the SAT. NRS: numerical rating scale.
