RESUMO
BACKGROUND: Previous studies have evaluated the implementation of behavioral approaches in individuals with chronic temporomandibular disorders (TMDs). OBJECTIVE: To evaluate the benefits of a behavioral approach to craniofacial pain. Second, we assessed the benefits of kinesiophobia, catastrophizing, mouth opening without pain, and forward head posture. METHODS: Individuals with chronic TMDs were treated for five weeks. The intervention group (n = 17) underwent pain neuroscience education, manual therapy, and therapeutic exercise, whereas the control group (n = 17) underwent manual therapy only. Outcomes were evaluated immediately, at seven and 19 weeks follow-up. The assessment tools used were the Craniofacial Pain Disability Inventory, Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, Mandibular Range of Motion Scale, and Cervical Range of Motion Tool. RESULTS: The interventions did not influence the differences in the improvements between the groups observed for craniofacial pain disability (inter-subject p 0.4). The intervention had a moderate influence on the improvement of kinesiophobia and catastrophizing (Inter-subject p 0.09 and 0.1 respectively) with a clinically significant effect size (Estimated mean (EM) -8.6 standard deviation (SD) ±3.48 p 0.019; and EM -7.6 SD ± 5.11 p 0.15 respectively). CONCLUSION: The behavioral approach improved catastrophizing and kinesiophobia outcomes in individuals with chronic TMDs.
RESUMO
BACKGROUND: Cluster headache (CH) is a type of headache that has a global prevalence of 0.5-3/1000 people, provokes severe, strictly unilateral pain through the first branch of the trigeminal nerve, and is associated with observable autonomous responses. CH provokes intense pain and decreases quality of life. OBJECTIVE: In this study, we aimed to carry out a systematic review of the effectiveness of non-invasive neuromodulation of the vagus nerve in patients with cluster headaches, which was registered on PROSPERO No. CRD42021265126. METHODS: Six databases were used from their date of inception to February 2023 to obtain studies with the group intervention of non-invasive neuromodulation of the vagus nerve for cluster headache, with outcomes based on pain attacks, duration, and disabilities. Data on the subjects, group intervention, main outcomes, and results were collected by two authors. RESULTS: The search provided 1003 articles, with three clinical trials being eligible for inclusion in the review. The methodological quality scores ranged from 6 to 8 points (mean: 7.3, SD: 0.8) out of a maximum of 10 points. The post-treatment results showed some positive effects using n-VNS as a treatment for cluster headache, more specifically regarding cervical neuromodulation of the vagus nerve. CONCLUSIONS: The systematic review found moderate-to-high-quality evidence supporting that n-VNS and cervical n-VNS may have some positive effects at the end of the treatment being effective to relieve the frequency and intensity of cluster headaches. The poor quantity of studies available and the lack of homogeneity in the study protocols did not allow the pooling of data for a meta-analysis.
RESUMO
This systematic review aims to summarise the evidence from studies that examined morphometric alterations of the deep neck muscles using diagnostic imaging (ultrasound imaging, magnetic resonance imaging, and computed tomography) in patients diagnosed with primary headache disorders (PHD). No previous reviews have focused on documenting morphometric changes in this population. We searched five databases (up to 12 November 2022) to identify the studies. The risk of bias (RoB) was assessed using the Quality in Prognostic Studies (QUIPS) tool and the overall quality of the evidence was assessed using The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. A total of 1246 studies were screened and five were finally included; most were at high RoB, and the overall level of confidence in results was very low. Only two studies showed a significant association between morphometric alterations of the deep neck muscles and PHD (p < 0.001); nevertheless, their RoB was high. Contradictory and mixed results were obtained. The overall evidence did not show a clear association between morphometric alterations of the deep neck muscles in patients diagnosed with PHD. However, due to the limited number of studies and low confidence in the evidence, it is necessary to carry out more studies, with higher methodological quality to better answer our question.
