Objective To assess the effectiveness of cervical manual therapy (MT) on patients with temporomandibular disorders (TMDs) and to compare cervico-craniomandibular MT vs cervical MT. Design Systematic review and meta-analysis (MA). Methods A search in PubMed, EMBASE, PEDro, and Google Scholar was conducted with an end date of February 2019. Two independent reviewers performed the data analysis, assessing the relevance of the randomized clinical trials regarding the studies’ objectives. The qualitative analysis was based on classifying the results into levels of evidence according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE). Results Regarding cervical MT, MA included three studies and showed statistically significant differences in pain intensity reduction and an increase in masseter pressure pain thresholds (PPTs), with a large clinical effect. In addition, the results showed an increase in temporalis PPT, with a moderate clinical effect. MA included two studies on cervical MT vs cervico-craniomandibular MT interventions and showed statistically significant differences in pain intensity reduction and pain-free maximal mouth opening, with a large clinical effect. Conclusions Cervical MT treatment is more effective in decreasing pain intensity than placebo MT or minimal intervention, with moderate evidence. Cervico-craniomandibular interventions achieved greater short-term reductions in pain intensity and increased pain-free MMO over cervical intervention alone in TMD and headache, with low evidence.

Purpose:To assess the effects of aerobic exercise (AE) on patients with migraine in terms of pain intensity, frequency and duration of migraine, and quality of life. Methods: A systematic review and meta-analysis of randomized controlled trials were conducted. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for relevant outcomes and were pooled in a meta-analysis using the random-effects model. Results: A total of 10 articles from 1950 to 2019 were included, involving 508 patients. The meta-analysis showed statistically significant differences in the decrease in pain intensity (five studies, n = 166; SMD = 1.25; 95% CI 0.47-2.04), frequency (six studies, n = 214; SMD = 0.76; 95% CI 0.32-1.2) and duration of migraine (four studies, n = 106; SMD = 0.41; 95% CI 0.03-0.8), in the short-term. In addition, the meta-analysis showed statistically significant differences in the increase in quality of life (four studies, n = 150; SMD = 2.7; 95% CI 1.17-4.24), even though the Egger's test suggested significant evidence of publication bias for the analysis of quality of life (intercept = 5.81; t = 6.97; P = .02). Conclusions: There is low-and moderate-quality evidence that in patients with migraine AE can decrease the pain intensity, frequency and duration of migraine and can also increase quality of life.
