Perceived Pain Extent is Not Associated With Widespread Pressure Pain Sensitivity, Clinical Features, Related Disability, Anxiety, or Depression in Women With Episodic Migraine

Abstract: Pain extent within the trigeminocervical area was not associated with any of the measured clinical outcomes and not related to the degree of pressure pain sensitization in women with episodic migraine. Further research is needed to determine if the presence of expanded pain areas outside of the trigeminal area can play a relevant role in the sensitization processes in migraine.

“…These findings would agree with the hypothesis that the presence of extra-median symptoms (14)(15)(16) that we did not find any significant association between pain extent and psychophysical outcomes of sensitization, i.e., widespread pressure pain or thermal pain hypersensitivity (except CPT over the carpal tunnel). Current findings would agree with the results previously found in some primary headaches such as migraine (40) or tension-type headache (41) but contrast with those previously reported in painful knee osteoarthritis (18) where larger pain extent was associated with higher pressure pain sensitivity. Similarly, the current study did not find any significant association between pain extent and clinical, psychological, and related-disability outcomes in women with CTS which is also in disagreement with previous findings found on painful knee osteoarthritis (18), whiplash-associated disorders (19), and fibromyalgia (20) where larger pain extent was associated with higher intensity of pain or worse psychological variables.…”

“…From the thirteen studies that were examined, two were excluded, the first one because it included asymptomatic individuals [ 11 ], and the second one because it was a randomized controlled clinical trial [ 19 ]. A total of eleven cross-sectional cohort studies [ 10 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ] were included in the final literature data mapping ( Figure 3 ).…”

“…All studies used digital software-based computation for calculating pain extent with six of them collecting data with digitalized PDs on a tablet [ 10 , 20 , 21 , 24 , 27 , 28 ] and five using a pen-to-paper approach [ 22 , 23 , 25 , 26 , 29 ]. Across all studies, the pain extent ranged from 6.7% to 22% (mean ± SD: 12.1% ± 5.3%), and in all cases its computation was software-based as per the inclusion criteria.…”

“…Pain drawings offer a practical way of quantifying pain extent and have been used to quantify the distribution of pain in patients with hip and knee OA, greater trochanteric pain syndrome, low back pain, fibromyalgia, carpal tunnel syndrome, chronic spinal pain, whiplash‐associated disorder, migraine, and tension‐type headaches . To date, only 1 study has examined the association between pain extent and clinical features of central sensitization in patients with OA .…”
