Fig. 1From: Evaluation of the pathophysiology of classical trigeminal neuralgia by blink reflex study and current perception threshold testingComparisons of the values of 5 Hz CPT between painful and non-painful sides at different times. There is a trend that the values of 5 Hz CPT on the painful side are lower than the non-painful side within the first month, but they evolved to be higher than the non-painful side after one month.
