Pain Sensitivity Comparison Between Individuals with Signs and Symptoms of Carpal Tunnel Syndrome and Healthy Controls

	s/s CTS	Healthy	Mean Difference (SE)	p- value	Cohen’s d
Thermal Threshold	43.70 (2.40)	44.88 (2.22)	1.18 (0.73)	0.12	0.51
Thermal Tolerance	48.70 (1.39)	49.06 (1.02)	0.36 (0.38)	0.36	0.30
Ramp and Hold	39.05 (24.46)	27.10 (24.37)	1.20 (0.77)	0.13	0.49
Temporal Summation	8.10 (16.86)	−2.35 (8.13)	10.45 (4.19)	0.02*	0.79
After Sensation	25.70 (23.86)	10.50 (6.66)	15.2 (12.4)	0.24	0.87
MP flexor retinaculum	11.80 (16.31)	3.60 (6.79)	0.82 (0.40)	0.05*	0.66
MP brachioradialis	28.80 (31.67)	10.75 (14.87)	1.81 (0.78)	0.03*	0.73

Presented in means (standard deviation). Thermal threshold and tolerance are provided as the temperatures at which the participant first indicated pain perception (threshold) and reported the inability to tolerate any greater temperature (tolerance). SE= standard error of difference. MP= mechanical pain sensitivity to 2.2 kg of force. χ² was used to determine between group differences in after sensation with a significantly greater proportion of individuals with signs and symptoms of carpal tunnel syndrome (s/s CTS) reporting after sensation (10/20) than healthy participants (4/20). Ratings for after sensation reported in the table are only for the participants who reported persistent pain 15 seconds following the final pulse in the temporal summation protocol (n=12).
