Electrochemical Skin Conductance as a Marker of Painful Oxaliplatin-Induced Peripheral Neuropathy

Table 3

(a) Neuropathic Pain Assessment. (1) Number of patients without neuropathic pain (null NPSI score). (2) Number of patients with neuropathic pain (positive NPSI score). (3-5) Number of patients with positive response at questions 10, 11 and 12. NPSI: Neuropathic Pain Symptoms Inventory.

Neuropathic Pain Assessment	n
(1) NPSI score = 0	16	44.4
(2) NPSI score > 0	20	55.5
(3) Pain caused by the contact with a cold object (Q10)	18	90
(4) Tingling (Q11)	9	45
(5) Swarming (Q12)	14	70

(b) Thermal Sensory Assessment. Thermal thresholds were measured with the MSA thermal stimulator on hands and feet (n = 36 patients): (i) Cold and Warm Detection Thresholds (CDT, WDT) are presented as relative values (expressed as variations of temperature from the basal temperature of 32°C). (ii) Cold and Heat Pain Thresholds (CPT, HPT) are presented as absolute temperature values.

Thermal Sensory Assessment	Hands (M ±ET)	Feet (M ±ET)
CDT ()	- 3.4 ± 2.2	- 7.0 ± 4.0
WDT ()	2.9 ± 2.0	11.6 ± 4.4
CPT ()	13.6 ± 6.7	12.8 ± 6.8
HPT ()	45.6 ± 4.1	48.6 ± 4.6
