Craniocervical Pain, Sleep Quality, Depressive Symptoms, and Physical Activity in Healthcare Workers During COVID-19 Pandemic. Pain Manag Nurs 2024; 25:e230-e235. [PMID: 38429200 DOI: 10.1016/j.pmn.2024.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 12/08/2023] [Accepted: 01/18/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND An increase in the workload and use of personal protective equipment by healthcare workers was observed during the COVID-19 pandemic. Due to the connections between craniocervical structures, symptoms such as neck pain and temporomandibular symptoms could be influenced by the use of PPE. AIMS To assess the prevalence of craniocervical pain, sleep quality, physical activity, and depressive symptoms and relationship among craniocervical symptoms in healthcare workers before and during the COVID-19 pandemic in Brazil. DESIGN Cross-sectional study. PARTICIPANTS Healthcare workers. SETTINGS An online questionnaire included a self-report of craniocervical pain intensity [orofacial pain, neck pain, and headache (Numerical Rating Scale)], sleep quality (Pittsburgh Sleep Quality Index), depressive symptoms (Patient Health Questionnaire two items) and physical activity (self-report). METHODS The sample analysis was performed by descriptive statistics, the paired t-test was used to compare symptoms intensity before and during the pandemic. The relationship between dependent and independent samples was assessed through McNemar test, Pearson's chi-squared test, and Student's independent t-test. A value of p < .05 was adopted as statistical significance. RESULTS Overall, 147 participants replied the questionnaires. Headache, neck pain, and orofacial pain complaints increased during the pandemic in healthcare workers (p < 0.001). Craniocervical pain was correlated with poor sleep quality, probable depression, and physical activity during the pandemic (p < 0.05). CONCLUSION Healthcare workers self-reported more craniocervical pain during the COVID-19 pandemic compared to before the pandemic. In addition, poor sleep quality, depressive symptoms, and physical inactivity were associated with craniocervical symptoms during this period.

Investigation of masticatory muscle thickness and mechanosensitivity of cervical and masticatory muscles in myofascial temporomandibular disorder patients with bruxism: A cross-sectional study. Musculoskelet Sci Pract 2024; 70:102919. [PMID: 38335810 DOI: 10.1016/j.msksp.2024.102919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 01/15/2024] [Accepted: 02/02/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVE Bruxism is a common problem associated with temporomandibular disorders (TMD). The aim of this study was to compare a patient group with Myofascial TMD and bruxism and a healthy control group in terms of masseter and temporal muscle thickness (clenching and resting), mechanosensitivity of neck and jaw muscles, craniofacial pain, and disability and emotional stress status. METHODS The study included 31 patients with myofascial TMD and bruxism (19 females, 12 males) with a mean age of 29.96 ± 8.12 years (range, 18-45 years), and a control group of 31 healthy subjects (19 females, 12 males) with a mean age of 27.58 ± 9.39 years years (range, 18-45 years). Masseter and temporal muscle thicknesses were evaluated with a mobile ultrasound device both at rest and when clenching the jaw. The mechanosensitivity values between the upper trapezius, obliquus capitis inferior, masseter and temporal muscles were measured with a digital algometer device. Craniofacial pain and disability level were evaluated with the Craniofacial Pain and Disability Index (CFPDI), and emotional stress levels with the Perceived Stress Scale-14 (PSS-14). RESULTS No difference was determined between the two groups in respect of the clenching and resting ratios of muscle thickness in any muscle (p > 0.05). The mechanosensitivity values in all muscles were lower in the myofascial TMD group than in the healthy group (p < 0.05). The CFPDI and PSS-14 scores were higher in the myofascial TMD group (p < 0.05). There was a moderate positive correlation between CFPDI, PSS-14 and Bruxism Frequency Score (p < 0.05). CONCLUSION The difference in mechanosensitivity and CFPDI values between the myofascial TMD patients with bruxism and the healthy control group indicates that the problem in this patient group has effects in the craniocervical and cervical regions. In addition, the correlation between CFPDI, PSS-14 and Bruxism Frequency Score in myofascial TMD patients suggests that this problem may be affected by the interaction of different parameters.

Abstract
Temporomandibular disorders (TMDs) are a group of conditions that cause pain and dysfunction in the temporomandibular joint (TMJ) and muscles that control mandibular movement. In most cases, the etiology is unclear and is considered multifactorial. Recent research suggests that some forms of TMD could be associated with specific TMJ morphological characteristics. This study aims to provide a review of the reported anatomical and degenerative morphological condylar characteristics of subjects with a clinical diagnosis of TMD as described with the use of CBCT imaging, as well as the detection of potential predisposing anatomical factors. This review was developed and reported in accordance with the PRISMA-ScR Checklist. A comprehensive search was performed in five databases. Reports were screened by two independent reviewers based on preselected inclusion and exclusion criteria. 45 studies were included in this review. The most frequently reported degenerative changes associated with TMD were condylar surface erosion, flattening, osteophytes, and sclerosis. Anatomical characteristics included a small condylar size and a posterior position of the condylar head in the TMJ. The anterosuperior area of the condylar head appears to be the most frequently affected. More studies are required to determine potential specific predisposing anatomical characteristics.

What are the best parameters of low-level laser therapy to reduce pain intensity and improve mandibular function in orofacial pain? A systematic review and meta-analysis. Disabil Rehabil 2023; 45:3219-3237. [PMID: 36263978 DOI: 10.1080/09638288.2022.2127933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 09/13/2022] [Accepted: 09/18/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE To determine the effectiveness of laser therapy for managing patients with orofacial pain (OFP). In addition, to determine which parameters provide the best treatment effects to reduce pain, improve function, and quality of life in adults with OFP. METHODS Systematic review. Searches were conducted in six databases; no date or language restrictions were applied. Studies involving adults with OFP treated with laser therapy were included. The risk of bias (RoB) was performed with the Revised Cochrane RoB-2. A meta-analysis was structured around the OFP type, and outcomes. Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) assessed the overall certainty of the evidence. RESULTS Eighty-nine studies were included. Most studies (n = 72, 80.9%) were considered to have a high RoB. The results showed that laser therapy was better than placebo in improving pain, maximal mouth open (MMO), protrusion, and tenderness at the final assessment, but with a low or moderate level of evidence. The best lasers and parameters to reduce pain are diode or gallium-aluminum-arsenide (GaAlAs) lasers, a wavelength of 400-800 or 800-1500 nm, and dosage of <25 J/cm2. CONCLUSIONS Laser therapy was better than placebo to improve pain, MMO, protrusion, and tenderness. Also, it was better than occlusal splint to improve pain, but not better than TENS and medication.Implications for rehabilitationLaser therapy was found to be good in improving pain, maximal mouth opening, jaw protrusion, and tenderness at the end of the treatment.For patients with all types of temporomandibular disorders (TMDs) (myogenous, arthrogenous, and mixed), the following lasers and parameters are recommended: diode or gallium-aluminum-arsenide (GaAlAs) laser, wavelength of 400-800 or 800-1500 nm, and a dosage <25 J/cm2.For patients with arthrogenous TMDs, the following lasers and parameters are recommended: Diode laser and a wavelength between 400 and 800 nm.For patients with myogenous TMDs, the following lasers and parameters are recommended: diode laser, wavelength between 800 and 1500 nm, and dosage of <25 J/cm2.For patients with mixed TMDs, the following lasers and parameters are recommended: diode, GaAlAs, or infrared laser, a wavelength of 800-1500 nm, a dosage >100 J/cm2, and an application time between 15 and 30 s or >60 seconds.

Abstract
OBJECTIVE To analyse the effectiveness of exercise therapy in improving pain and active or passive maximum mouth opening in patients with temporomandibular disorders. DATA SOURCES PubMed Medline, Web of Science, Scopus, CINAHL Complete and Physiotherapy Evidence Database, until April 2022, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. REVIEW METHODS We included randomized controlled trials evaluating the effect of exercise therapy on pain and on active and passive maximum mouth opening in patients with temporomandibular disorders. Effect size was calculated using Cohen's standardized mean difference (SMD) and their 95% confidence interval (95% CI) in a random-effects model. RESULTS A total of 16 studies with 812 participants were included. Exercise therapy is effective in reducing pain (SMD: -0.58; 95% CI: -1.01 to -0.12) and increasing the pain pressure threshold (SMD: 0.45; 95% CI: 0.14-0.76), active and passive maximum mouth opening (SMD: 0.43; 95% CI: 0.14-0.71 and SMD: 0.4; 95% CI: 0.06-0.75, respectively). Subgroup analyses showed more effect of exercise therapy more splints versus splints on pain (SMD: -0.5; 95% CI: -0.73 to -0.26), active and passive maximum mouth opening (SMD: 1.14; 95% CI: 0.22-2.07 and SMD: 0.56; 95% CI: 0.06-1.06, respectively). On pain pressure threshold, exercise therapy was better than physiotherapy approach (manual therapy and electrotherapy) (SMD: 0.48; 95% CI: 0.09-0.87). CONCLUSIONS Therapeutic exercise is an effective therapy to reduce pain and increase pain pressure threshold and active and passive maximum mouth opening in patients with temporomandibular disorders.

Abstract
BACKGROUND Ischemic compression is widely used to clinically treat neck pain. However, no meta-analysis has been conducted to evaluate the effects of this process on neck pain. OBJECTIVE This study aimed to evaluate the effects of ischemic compression on the myofascial trigger points for improving neck pain-related symptoms (mainly pain, joint mobility limitation and function limitation) and to compare ischemic compression with other therapies. METHODS Electronic searches were conducted in PubMed, OVID, Web of Science, EBSCO, SCOUPS, Cochrane Library, PEDro, Wanfang, CNKI and Chinese VIP Database in June 2021. Only randomised controlled trials on the effects of ischemic compression on neck pain were included. The major outcomes were pain intensity, pressure pain threshold, pain-related disability and range of motion. RESULTS Fifteen studies involving 725 participants were included. Significant differences were observed between ischemic compression and sham/no treatment group in pain intensity, pressure pain threshold and range of motion immediately and in the short term. Significant effect sizes of dry needling were observed over ischemic compression in terms of improving pain intensity (SMD = 0.62; 95% CI: 0.08 to 1.16; P= 0.02), pain-related disability (SMD = 0.68; 95% CI: 0.19 to 1.17; P= 0.007) and range of motion (MD =-2.12; 95% CI: -2.59 to -1.65; P< 0.001) immediately after treatment. Dry needling also showed a significant small effect size for the short-term reduction of pain (SMD = 0.44; 95% CI: 0.04 to 0.85; P= 0.03). CONCLUSION Ischemic compression can be recommended in the immediate and short-term pain relief and increase in the pressure pain threshold and range of motion. Dry needling is superior to ischemic compression in relieving pain and improving pain-related disability and range of motion immediately after treatment.

Abstract
The associations of mental stress with decayed teeth in children and periodontitis in old-aged adults have been described. However, the associations for young adults were not clear. This study aimed to examine the associations of decayed teeth and localized periodontitis with mental stress in young adults. This study included 334 military recruiters, aged 19-45 years in Taiwan. Mental stress was assessed by the brief symptom rating scale-5 (BSRS-5), including five domains: anxiety, depression, hostility, interpersonal sensitivity and insomnia (maximum score of 20). Those with symptomatic mental stress were defined as having BSRS-5 > 5 (n = 34). Multiple linear and logistic regression models were used to determine the associations of decayed tooth numbers and periodontitis with BSRS-5, with adjustments for age, sex, education level, physical activity, body weight category and smoking status. The BSRS-5 was positively correlated with decayed tooth numbers [β: 0.26 (95% confidence interval: 0.01-0.52)]. Those who had more than two decayed teeth [odds ratio: 3.59 (1.52-8.46)] had a higher risk of symptomatic mental stress. In contrast, the correlation between BSRS-5 and localized severer periodontitis was null. Our study recommended that decayed teeth instead of localized periodontitis, was a risk factor for mental stress in young adults.

Abstract
Objective. To survey the clinical manifestations and imaging features of temporomandibular disorders (TMD) and analyze the risk factors for pathogenesis/prognosis through a case-control study based on psychogenic factors of patients. Methods. According to the inclusion criteria, 200 adult patients were randomly enrolled from the maxillofacial department of our hospital from January 2020 to May 2021, including 100 patients with TMD as the study group and 100 healthy patients as the control group. The study group can be assigned into four subgroups according to their clinical manifestations: (1) articular area or/and masticatory muscle pain group, (2) mandibular movement abnormality group, (3) joint murmur group, and (4) two or more symptom groups. Based on the study of psychogenic factors of patients, the clinical manifestations and imaging features of TMD were determined, and the risk factors for pathogenesis/prognosis were analyzed. Results. The distribution of psychological status in the TMD group was higher than that in the control group (
). The distribution of anxiety, depression, and somatic symptoms in the TMD group was significantly different from that in the control group (
). Anxiety, depression, and somatic symptoms were the risk factors for TMD. Compared with the control group, the incidence of abnormal MRI images in patients with temporomandibular disorders was significantly different (
). There were significant differences in psychological status (anxiety, depression, and somatic symptoms) among the three groups (
). Anxiety, depression, and somatic symptoms were the risk factors for abnormal mandibular movement and joint tremor and murmur (
). Somatic symptoms were the risk factors for various clinical symptoms of TMD (
). Depression was the risk factor for pain (
). Conclusion. In patients with TMD, MRI can early identify disc abnormalities and other related imaging features, which is helpful for more comprehensive clinical evaluation and treatment of TMD patients. There exhibits no significant difference in psychological status (anxiety, depression, and somatic symptoms) of patients with different clinical symptoms, and abnormal psychological status may be one of the risk factors leading to different clinical symptoms and development of different types of TMD patients.

Abstract
BACKGROUND AND OBJECTIVES Temporomandibular disorders (TMD) represent a group of diseases occurred in the temporomandibular joint (TMJ) and its surrounding tissues. In epidemiological studies, up to 75% of adults have shown at least one sign of temporomandibular disorders during their examinations. The incongruous biomechanical environment in the TMJ is the main pathogenic factor of TMD. This study attempts to determine the mechanical differences in different groups of TMD patients through biomechanics and to explain the mechanical pathogenesis of TMD according to various cases. METHODS Eleven control subjects and eleven TMD patients were selected and divided into three groups: the control group, bilateral TMD group, and unilateral TMD group. The contact stresses of the articular discs, condyles and temporal bones were analyzed using finite element method and statistical analysis of variance. RESULTS The results indicated that the contact stresses in the joints with TMD were significantly greater in the Bi-Group (Bilateral TMD patients) compared to the Control-Group. The TMD side always exhibited greater stresses in the Uni-Group [Unilateral TMD patients) under various conditions (clenching on the TMD side or asymptomatic side). The greatest stress of all the groups occurred at the contralateral side with TMD when clenching on the asymptomatic side. CONCLUSIONS Excessive protection would lead to greater stress on the affected side and increased TMD risk on the asymptomatic side. Clinically, the abnormal stress distributions of the disc represented poor buffering and articular clicking. The asymmetric distributions of the articular fossa manifested the deviation of mouth opening or inconsistent TMJ loading.

Abstract
Background Cervical spine dysfunction is a condition with high personal, social, and economic impact worldwide. Although its etiology is described as multifactorial, there is a need for further clarification. The literature has demonstrated the anatomical, physiological, and pathophysiological relationship among the cervical spine, temporomandibular joint, and visceral system. To guide and contribute to the accuracy of the physical assessment performed by nurses, we will study the influence of the stomatognathic system and viscerosomatic reflexes on pain and joint stiffness of the cervical spine. Objective The aim of this study is to describe a pilot study protocol to investigate the influence of the stomatognathic system and viscerosomatic reflexes on cervical structures. Methods A pilot study with a quasi-experimental design was conducted with 50 volunteers from the university population of the Universidade Católica Portuguesa-Porto. We studied the influence of changes in the usual intercuspation, the occlusal deprogramming, and the pressure stimulus of the reflex skin region of the ilium/colon in the cervical spine. This study was divided into 2 phases. In the first phase, we performed the kinematic and pain analysis during the passive mobilization of the upper cervical spine using the Motion Capture System at the Motion Capture Laboratory at UCP-Porto and the Visual Analog Scale. In the second phase, we evaluated the pain threshold on palpation of the erector neck muscles and the structures of the stomatognathic system using algometry. The influence of viscerosomatic reflexes on the structures of the stomatognathic system was also analyzed. Results Selection and preparation of the data collection site, acquisition of materials, constitution of the sample group and data collection were completed. The analysis of the results is being carried out.

Abstract
The five osteopathic models recognized by the American Association of Colleges of Osteopathic Medicine guide clinicians in the evaluation and therapeutic choice which must be the most appropriate concerning the patient's needs. Skeletal muscles represent an important interpretation, such as screening and treatment, on which these models are based. A muscle district that is not considered by the usual osteopathic practice is the tongue. The lingual complex has numerous functions, both local and systemic; it can adapt negatively in the presence of pathology, just as it can influence the body system in a non-physiological manner if it is a source of dysfunctions. This paper, the first of its kind in the panorama of scientific literature, briefly reviews the anatomy and neurophysiology of the tongue, trying to highlight the logic and the need to insert this muscle in the context of the five osteopathic models. The clinician's goal is to restore the patient's homeostasis, and we believe that this task is more concrete if the patient is approached after understanding all the contractile districts, including the tongue.

Cervical musculoskeletal disorders in patients with temporomandibular dysfunction: A systematic review and meta-analysis. J Bodyw Mov Ther 2020; 24:84-101. [PMID: 33218570 DOI: 10.1016/j.jbmt.2020.05.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 03/18/2020] [Accepted: 05/01/2020] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To verify which are the neck musculoskeletal disorders presented by individuals with temporomandibular disorders (TMD). METHODS It is a systematic review and meta-analysis that were included cohort, case-control and cross-section studies that analyzed the presence of cervical musculoskeletal disorders in individuals with TMD, with age between 18 and 55 years. The searches were carried out in the databases: Medline/PubMed, Cinahl, Web of Science, Cochrane, Lilacs and Scopus; and there was no linguistic or temporal restriction. The evidence quality was evaluated by GRADE system and methodological quality by Newcastle-Ottawa Quality Assessment Scale (NOS) and the risk of publication bias assessed by the funnel plot graph. The data was quantitatively analyzed by the meta-analysis using the mean differences (MD) as an effect measure. RESULTS There were included 21 manuscripts in the synthesis, of theses 16 were evaluated by meta-analysis with methodological quality ranging from poor to excellent by NOS scale. Individuals with TMD present lower endurance of extensor neck muscle compared to TMD-free (MD = -194.66s [95%CI: 212.44;-176.88]), with moderate to excellent quality. As, upper neck hymobility on the right (MD = -8.59° (95%CI: -10.43°;-6.75°) and left (MD = -7.99° (95%CI: -9.63°;-6.35°), and in all global neck movements. Also, individuals with TMD presented worse self-reported neck disability (MD = 7.91 (95%CI: 7.39; 8.43)) compared to free-TMD. CONCLUSION There is moderate and strong evidence that patients with TMD present lower endurance of extensor neck muscle, global and upper neck hypomobility, worse self-reported neck disability, however, their cranio-cervical posture is similar to individuals without TMD, based on a moderate to excellent methodological quality.

Correlations between Sleep Bruxism and Temporomandibular Disorders. J Clin Med 2020; 9:jcm9020611. [PMID: 32102466 PMCID: PMC7074179 DOI: 10.3390/jcm9020611] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 02/21/2020] [Accepted: 02/22/2020] [Indexed: 12/31/2022] Open
Abstract
The aim of this study was to identify correlations between sleep bruxism (SB) and temporomandibular disorders (TMD) as diagnosed by means of the research diagnostic criteria for temporomandibular disorders (RDC/TMD). Sleep bruxism was diagnosed on the basis of I) validated questionnaires, II) clinical symptoms, and III) electromyographic/electrocardiographic data. A total of 110 subjects were included in the study. Fifty-eight patients were identified as bruxers and 52 as nonbruxers. A psychosocial assessment was also performed. An RDC/TMD group-I diagnosis (myofascial pain) was made for 10 out of 58 bruxers, whereas none of the nonbruxers received a diagnosis of this type. No significant differences were found between bruxers and nonbruxers with regard to RDC/TMD group-II (disc displacement) and group-III (arthralgia, arthritis, arthrosis) diagnoses. Somatization was significantly more common among bruxers than nonbruxers. Multivariate logistic regression analysis revealed that somatization was the only factor significantly correlated with the diagnosis of myofascial pain. The results of this study indicate a correlation between myofascial pain, as diagnosed using the RDC/TMD, and somatization. It seems that somatization is a stronger predictor of an RDC/TMD diagnosis of myofascial pain than sleep bruxism is.
