Objectives: The objective of this observational study was to establish the possible presence of confounders on the association between temporomandibular disorders (TMD) and headaches in a patient population from a TMD and Orofacial Pain Clinic. Materials and Methods: Several subtypes of headaches have been diagnosed: self-reported headache, (probable) migraine, (probable) tension-type headache, and secondary headache attributed to TMD. The presence of TMD was subdivided into 2 subtypes: painful TMD and function-related TMD. The associations between the subtypes of TMD and headaches were evaluated by single regression models. To study the influence of possible confounding factors on this association, the regression models were extended with age, sex, bruxism, stress, depression, and somatic symptoms. Results: Of the included patients (n=203), 67.5% experienced headaches. In the subsample of patients with a painful TMD (n=58), the prevalence of self-reported headaches increased to 82.8%. The associations found between self-reported headache and (1) painful TMD and (2) function-related TMD were confounded by the presence of somatic symptoms. For probable migraine, both somatic symptoms and bruxism confounded the initial association found with painful TMD. Discussion: The findings of this study imply that there is a central working mechanism overlapping TMD and headache. Health care providers should not regard these disorders separately, but rather look at the bigger picture to appreciate the complex nature of the diagnostic and therapeutic process.

Background: Uncertainties still exist about the role of playing musical instruments on the report of musculoskeletal complaints and headache.Objectives: To evaluate the prevalence of and risk indicators for symptoms of temporomandibular disorders, pain in the neck or shoulder, and headache among musicians.Methods: A questionnaire was distributed among 50 Dutch music ensembles.Results: The questionnaire was completed by 1470 musicians (response rate 77.0%). Of these, 371 musicians were categorised as woodwind players, 300 as brass players, 276 as upper strings players, 306 as vocalists and 208 as controls; nine musicians had not noted their main instrument. The mean age was 41.6 years (standard deviation [SD] 17.2), and 46.5% were male. Irrespective of instrumentalist group, 18.3% of the musicians reported TMD pain, 52.5% reported pain in the neck and shoulder area, and 42.5% reported headache. Of the functional complaints, 18.3% of the musicians reported TMJ sounds, whereas a jaw lock or catch on opening or on closing was reported by 7.1% and 2.4%, respectively. TMD pain was associated with playing a woodwind instrument, whereas pain in the neck and shoulder was associated with playing the violin or viola. For each complaint, oral behaviours were found as risk indicator, supplemented by specific risk indicators for the various complaints.Conclusions: The current finding that pain‐related symptoms varied widely between instrumentalist groups seems to reflect the impact of different instrument playing techniques. Playing a musical instrument appears not the primary aetiologic factor in precipitating a functional temporomandibular joint problem.

Headache is a common disorder which may lead to substantial socio-economic loss. Treatment options include self-management strategies, medication and physiotherapy. Physiotherapists need to be able to screen for the presence of migraine and tension-type headache (TTH), so they can adjust their treatment strategies to the type of headache. A quick screening questionnaire to recognize migraine and TTH in the physiotherapy practice is needed. The aim of this study was to create a headache screening questionnaire based on the ICHD-3 beta criteria for migraine and TTH, and to establish its content and criterion validity. A cross-sectional design was used during the validation phase of the study. A screening questionnaire was developed for migraine and TTH. Content validity was checked by the research group and a headache research expert. For validation of this questionnaire, patients from the headache clinic of the Canisius Wilhelmina Hospital in Nijmegen were recruited. The outcome of the questionnaire was compared to the ICHD-3 beta diagnosis of the headache specialist. For criterion validity, sensitivity, specificity, likelihood ratios, and positive- and negative predictive values were calculated. A 10-item questionnaire has been developed: the Headache Screening Questionnaire. For validation of the Dutch version (HSQ-DV), 105 patients were included in the study. The sensitivity and specificity were 0.89 and 0.54 respectively for probable migraine, and for probable TTH 0.92 and 0.48 respectively. The HSQ-DV is a sensitive screening tool to detect patients with probable migraine and probable TTH.

Physical therapy is regarded an effective treatment for temporomandibular disorders (TMD). Patients with TMD often report concomitant headache. There is, however, no overview of the effect of physical therapy for TMD on concomitant headache complaints. The aim of this study is to systematically evaluate the literature on the effectiveness of physical therapy on concomitant headache pain intensity in patients with TMD. PubMed, Cochrane and PEDro were searched. Randomized or controlled clinical trials studying physical therapy interventions were included. Patients with TMD and headache. The Cochrane risk of bias tool was used to assess risk of bias. Individual and pooled between-group effect sizes were calculated according to the standardized mean difference (SMD) and the quality of the evidence was rated using the GRADE approach. and manual therapy on both orofacial region and cervical spine. There is a very low level of certainty that TMD-treatment is effective on headache pain intensity, downgraded by high risk of bias, inconsistency and imprecision. The methodological quality of most included articles was poor, and the interventions included were very different. Physical therapy interventions presented small effect on reducing headache pain intensity on subjects with TMD, with low level of certainty. More studies of higher methodological quality are needed so better conclusions could be taken.

Background: Treatment of temporomandibular disorder (TMD) currently consists of a combination of noninvasive therapies and may be supported by e-Health. It is, however, unclear if physical therapists and patients are positive towards the use of e-Health. Purpose: To assess the needs, facilitators and barriers of the use of an e-Health application from the perspective of both orofacial physical therapists and patients with TMD. Methods: A descriptive qualitative study was performed. Eleven physical therapists and nine patients with TMD were interviewed using a topic guide. Thematic analysis was applied, and findings were ordered according to four themes: acceptance of e-Health, expected utility, usability and convenience. Results: Physical therapists identified the need for e-Health as a supporting application to send questionnaires, animated exercises and evaluation tools. Key facilitators for both physical therapists and patients for implementing e-Health included the increase in self-efficacy, support of data collection and personalization of the application. Key barriers are the increase of screen time, the loss of personal contact, not up-to-date information and poor design of the application. Conclusions: Physical therapists and patients with TMD are positive towards the use of e-Health, in a blended form with the usual rehabilitation care process for TMD complaints.
