Curiel-Montero F, Alburquerque-Sendín F, Fernández-de-las-Peñas C, Rodrigues-de-Souza DP. Has the Phase of the Menstrual Cycle Been Considered in Studies Investigating Pressure Pain Sensitivity in Migraine and Tension-Type Headache: A Scoping Review. Brain Sci 2021; 11:1251. [PMID: 34573271 PMCID: PMC8472201 DOI: 10.3390/brainsci11091251] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 09/13/2021] [Accepted: 09/18/2021] [Indexed: 01/03/2023] Open
Abstract
OBJECTIVE The aim of this scoping review was to identify if the phase of the menstrual cycle was considered in observational studies comparing pressure pain sensitivity between women with migraine or tension-type headache (TTH) and headache-free women. METHODS A systematic electronic literature search in PubMed, Medline, Web of Science, Scopus, and CINAHL databases was conducted. Observational studies including one or more groups with TTH and/or migraine comparing pressure pain thresholds (PPTs) were included. The methodological quality (risk of bias) was assessed with the Newcastle-Ottawa Scale. Authors, objectives, inclusion/exclusion criteria, size sample, female sample, tool to assess PPTs, mean age, and the use of any medication were extracted and analyzed independently by two authors. RESULTS From a total of 1404 and 1832 identified articles for TTH and migraine, 30 and 18 studies satisfied the criteria and were included. Nineteen (63.4%) studies assessing TTH patients and eleven (61.1%) assessing migraine patients showed a high risk of bias. The most common flaws were attributed to improper selection of control and control over other additional factors. Based on the systematic review, just one study including TTH and one including migraine patients considered the menstrual cycle. CONCLUSION The results of this scoping review identified that the phase of the menstrual cycle has been rarely considered in studies investigating sensitivity to pressure pain in primary headaches, such as TTH or migraine, although there is evidence showing the relevance of the phase of the menstrual cycle in pain perception.

Abstract
Abstract
Objective
The aim of this study was to thoroughly phenotype a group of chronic tension-type headache (CTTH) patients.
Methods
Fifteen CTTH patients diagnosed according to the International Classification of Headache Disorders–3 and 15 healthy controls were included in this study. Furthermore, 70 healthy controls were included to establish normative values. Quantitative sensory testing (QST), including temporal summation of pain (TSP), conditioned pain modulation (CPM), and psychological and sleep variables, was assessed in a single session. TSP and CPM were then combined to build pain modulation profiles (PMP) for each individual.
Results
No difference was found between groups for PMP, TSP, and CPM. However, 10 CTTH patients showed a pronociceptive PMP, with 8 related to a deficient CPM and 2 to both a deficient CPM and increased TSP. Increased cold detection thresholds were the most common sensory disturbance found in CTTH patients. Significant differences were seen between groups for pain catastrophizing, depression, and sleep quality although not all patient’s scores were above the clinically meaningful cutoffs.
Conclusions
In summary, CTTH patients presented with different PMP. These PMP may be related to increased TSP, deficient CPM, alterations in thermal detection that may be related to autonomic dysregulation, or a combination of all three. Overall, this suggests that due to their heterogeneous pathophysiology, CTTH patients should be managed according to their underlying pathophysiology and not with a one-size-fits-all approach.

Abstract
OBJECTIVE This meta-analysis evaluates pressure pain sensitivity values in symptomatic and distant pain-free areas comparing individuals with tension-type headache to controls. DATABASES AND DATA TREATMENT Electronic databases were searched for cross-sectional or prospective case-control studies comparing pressure pain thresholds in patients with tension-type headache to headache-free controls. Data were extracted by three reviewers. The methodological quality was assessed by the Newcastle-Ottawa Quality Assessment Scale. Meta-analyses of trigeminal, extra-trigeminal (neck) and distant pain-free areas in tension-type headache were compared to headache-free controls. Frequency of tension-type headache and gender were taken into account. RESULTS Twenty studies were included. Patients with tension-type headache exhibited lower pressure pain thresholds than headache-free controls: Trigeminal (MD -49.11 kPa, 95% CI -66.05 to -32.17), cervical spine (MD -88.17 kPa, 95% CI -108.43 to -67.92) and distant pain-free areas (MD -98.43 kPa, 95% CI -136.78 to -60.09). Differences were significant for chronic, episodic, and mixed episodic and chronic tension-type headache within the trigeminal and neck (symptomatic areas), but only significant for chronic tension-type headache (MD -102.86, 95% CI -139.47 to -66.25 kPa) for distant pain-free areas. In general, women had lower pressure pain thresholds than men. The methodological quality ranged from fair (45%) to good (40%). The results showed a high heterogeneity and publication bias. CONCLUSION This first meta-analysis addressing pressure pain thresholds differences in symptomatic and distant pain-free areas between patients with tension-type headache and controls found low to moderate evidence supporting the presence of pressure pain hypersensitivity in the trigeminal and neck areas in tension-type headache in comparison with headache-free controls. Sensitivity to pressure pain was widespread only in chronic, not episodic, tension-type headache (moderate evidence).Registration number: https://doi.org/10.17605/OSF.IO/R29HY.

Abstract
INTRODUCTION The purpose of this study was to clearly characterize the intramuscular nerve distributions of the splenius capitis and splenius cervicis muscles that are both responsible for the onset of a chronic tension type headache and to use this information to identify the effective botulinum toxin (BoNT) injection sites. MATERIALS AND METHODS Ten splenius capitis and splenius cervicis specimens were subjected to Sihler's staining to reveal intramuscular nerve arborization patterns and determined the optimal location for BoNT injection. RESULTS Nerve distribution patterns in the splenius capitis were identified as nerve pathways that travel down toward the origin point and others that travel up toward the insertion point. This neuromuscular innervation from the central (50%) point was distributed evenly in these two directions. The neural pathways of splenius cervicis traveled vertically from the insertion point to the origin point. If the length from the muscle origin point to the insertion point is normalized to 100%, motor neurons innervate the muscle from around the 30% to the 70% point. CONCLUSIONS The safest and most-effective BoNT injection sites for the splenius capitis and splenius cervicis were found at around the 50% point and the 30% to the 70% point, respectively.

Abstract
BACKGROUND Sensitivity of tissues can be measured by algometry. Decreased pressure pain thresholds over the cranio-cervical area are supposed to reflect signs of sensitization of the trigemino-cervical nucleus caudalis. A systematic review was conducted to assess the current scientific literature describing pressure pain threshold (PPT) values over the cranio-cervical region in patients with migraine, tension-type headache (TTH), and cervicogenic headache (CeH). A literature search was executed in three databases. The search strategy included the following keywords: migraine, TTH, CeH, PPT and algometry. A total of 624 papers was identified of which relevant papers were subsequently assessed for methodological quality. Twenty-two selected papers were assessed by two independent reviewers and the majority of studies scored low risk of bias on the selected items. Mean PPT values of several sites measured in the cranio-cervical region in patients with migraine, chronic TTH and CeH scored lower values compared to controls. The trapezius muscle (midpoint between vertebrae C7 and acromion) was the most frequently targeted site and showed significantly lower PPT values in adults with migraine (pooled standardized mean difference kPa: 1.26 [95%CI -1.71, -0.81]) and chronic TTH (pooled standardized mean difference kPa: -2.00 [95%CI -2.93, -1.08]). Most studies found no association between PPT values and headache characteristics such as frequency, duration or intensity. Further standardization of PPT measurement in the cranio-cervical region is recommended.

Abstract
Background: Chronic primary headache disorders are associated with frequent, severe pain and significant functional impairment, with treatment remaining challenging. Objective: We examined the feasibility and safety of a novel brain [transcranial direct current stimulation (tDCS)] and spinal cord stimulation [trans-spinal cord direct current stimulation (tsDCS)] treatment in chronic headache. Methods: Nine participants (3 males; aged, 40 ± 15 years) suffering from chronic daily headache, chronic tension-type headache, or chronic migraine received the combined brain and spinal cord intervention for 5 consecutive days. Stimulation was applied for a total of 40 minutes (20 minutes of tDCS followed by 20 minutes of tsDCS) at 1 mA. Pain sensitivity and headache symptoms (frequency, severity, duration, and medications recorded via a headache diary, 4 weeks before and after treatment) were assessed. Results: The treatment was safe, feasible, and well tolerated. Headache frequency was reduced following the treatment (p = 0.026) in chronic tension-type headache and chronic migraine, but not in chronic daily headache. Headache severity was reduced immediately post-treatment in 67% of sessions. A trend towards a reduction in medication use was observed (p = 0.075). No changes in headache severity (p = 0.16) or duration (p = 0.34) were present. Conclusion: These data suggest that combined tDCS and tsDCS intervention is safe and feasible, and may improve headache frequency in patients with chronic primary headache disorders.

Abstract
BACKGROUND A wide range of physical tests have been published for use in the assessment of musculoskeletal dysfunction in patients with headache. Which tests are used depends on a physiotherapist's clinical and scientific background as there is little guidance on the most clinically useful tests. OBJECTIVES To identify which physical examination tests international experts in physiotherapy consider the most clinically useful for the assessment of patients with headache. DESIGN/METHODS Delphi survey with pre-specified procedures based on a systematic search of the literature for physical examination tests proposed for the assessment of musculoskeletal dysfunction in patients with headache. RESULTS Seventeen experts completed all three rounds of the survey. Fifteen tests were included in round one with eleven additional tests suggested by the experts. Finally eleven physical examination tests were considered clinically useful: manual joint palpation, the cranio-cervical flexion test, the cervical flexion-rotation test, active range of cervical movement, head forward position, trigger point palpation, muscle tests of the shoulder girdle, passive physiological intervertebral movements, reproduction and resolution of headache symptoms, screening of the thoracic spine, and combined movement tests. CONCLUSIONS Eleven tests are suggested as a minimum standard for the physical examination of musculoskeletal dysfunctions in patients with headache.

Abstract
OBJECTIVES The jaw-stretch reflex (JSR) was studied in both patients and healthy participants in order to investigate the possible long-term impact of orthognathic surgery on the motor function of the masticatory system. DESIGN JSR was measured in patients before surgery (PC), 1year after surgery (PS) and in healthy controls (HC) (N=31 in each group). JSR was evoked by a standardized stretch device and recorded bilaterally from masseter and anterior temporalis muscles using surface electromyography (EMG). RESULTS The peak-to-peak amplitude (which was normalized to pre-stimulus EMG activity) of JSRs in PC and PS were significantly smaller than in HC (P<0.001; P<0.001). The onset latency in PS was significantly longer compared with HC (P<0.05). The duration of JSR in PS was significantly longer than in HC and PC (P<0.001; P<0.05). CONCLUSION Patients with dentofacial deformities are characterized by reduced JSR amplitude. The delayed onset and elongated duration of JSR might be potential indicators of a long-term surgical impact on the motor function of the masticatory system.

Abstract
Introduction Individuals with tension-type headache (TTH), in addition to headache pain, typically suffer from pericranial muscle tenderness and increased cervical muscle tone. Physical and physiological outcomes related to musculoskeletal function, however, are not commonly assessed in clinical studies and not systematically proposed as outcome measures in headache-related practice guidelines. Objectives To review which musculoskeletal outcomes are used in the clinical assessment of patients with TTH and which are associated with headache pain and related dysfunction. Methods: Literature searches were performed in MEDLINE, PubMed, the Cochrane databases and EMBASE using terms relating to musculoskeletal physical outcomes in TTH. Results Twenty-six studies met selection criteria. Physiological outcomes typically reported in laboratory studies were trigger points, pressure pain threshold, range of motion and tenderness. A greater number of trigger points and lower pressure pain threshold were reported in patients with episodic TTH in comparison with healthy subjects. Individuals with chronic TTH, when compared with non-headache controls, consistently showed a greater number of trigger points, a lower value of pressure pain threshold and a more severe forward head posture. Conclusion Musculoskeletal outcomes, such as trigger points, pressure pain threshold and forward head posture should inform TTH pathophysiology, diagnosis and interdisciplinary patient care.
