Table 2. Representation of VAS of pain in rheumatoid arthritis patients before and after motor imagery and mental calculations.

This table shows the comparison in resting motor threshold at baseline in the motor imagery and the mental calculation groups (P = 0.430). Data were checked for normality using the Shapiro-Wilk normality test. A two-group comparison was done by standard t-test. Data have been expressed as mean ± SD.

VAS, visual analogue scale.

VAS	Motor imagery	Mental calculation
Pre-procedure	5.5 ± 0.97	5 ± 1.24
Post-procedure	5.1 ± 0.87	4.9 ± 1.1
P-value	0.103	0.342
