Abstract
OBJECTIVE To evaluate craniocervical posture and hyoid bone position in patients with and without temporomandibular joint disorder (TMD). METHODS A total of 113 people were included in the study, including 55 TMD patients and 58 healthy controls. Using lateral cephalograms, the craniofacial, craniocervical, and hyoid bone positions of the participants were evaluated in terms of 27 variables. RESULTS There was no significant difference in craniocervical angles between participants with or without TMD. While the Hy-B, Hy-NSL, Hy-NL measurements and FMA (°), AFH (mm) measurements of participants with TMD were lower than the control group, the hyoid angle was greater than the control group. CONCLUSION These study findings provide evidence that TMD is not related to craniocervical posture but to the position of the hyoid bone and craniofacial morphology.

Abstract
OBJECTIVE To investigate biomechanics, muscle performance, and disability of the craniocervical region in temporomandibular disorder (TMD) patients and compare them with controls. METHODS Craniocervical posture was evaluated using lateral photography and radiography. Range of motion, muscle performance, disability, and TMD severity were assessed using an inclinometer, Functional Strength Testing of Cervical Spine, Neck Disability Index, and Fonseca Anamnestic Index, respectively. RESULTS Compared to the control group, the TMD group demonstrated higher cervical flexion angle (p=0.005) and neck disability (p<0.001) as well as lower cervical extension (p=0.040), right cervical rotation (p=0.005), left cervical rotation (p<0.001), and tragus-C7-horizontal (p=0.048) angles, and reduced muscle performances (p≤0.001). Most patients had higher than normal craniocervical angle (p<0.001). Muscle performance in each cervical motion (p<0.005) and disability (p<0.001) were associated with TMD severity in the TMD group. CONCLUSION Biomechanics, muscle performance, and disability of craniocervical region were altered in the TMD group.

Abstract
AIMS To examine the effect of manual therapy applied to the cervical joint for reducing pain and improving mouth opening and jaw function in people with TMDs. METHODS A systematic review of randomized controlled trials was performed. Participants were adults diagnosed with TMDs. The experimental intervention was manual therapy applied to the cervical joint compared to no intervention/placebo. Outcome data relating to orofacial pain intensity, pressure pain threshold (PPT), maximum mouth opening, and jaw function were extracted and combined in meta-analyses. RESULTS The review included five trials involving 213 participants, of which 90% were women. Manual therapy applied to the cervical joint decreased orofacial pain (mean difference: -1.8 cm; 95% CI: -2.8 to -0.9) and improved PPT (mean difference: 0.64 kg/cm2; 95% CI: 0.02 to 1.26) and jaw function (standardized mean difference: 0.65; 95% CI: 0.3 to 1.0). CONCLUSION Manual therapy applied to the cervical joint had short-term benefits for reducing pain intensity and improving jaw function in women with TMDs. Further studies are needed to improve the quality of the evidence and to investigate the maintenance of benefits beyond the intervention period.

Abstract
PURPOSE To translate the Craniofacial Pain and Disability Inventory into Turkish (CF-PDI/T) and to examine its reliability and validity. MATERIALS AND METHODS Cultural adaptation of CF-PDI/T was conducted according to international standards. The psychometric analyses included reliability by internal consistency (Cronbach's alpha) and test/retest reliability (intraclass correlation coefficient, ICC); structural validity was evaluated with exploratory factor analysis (EFA), confirmatory factor analysis (CFA); and construct validity was investigated by matching (a priori hypotheses) the CF-PDI/T with the Numeric Rating Scale (NRS), Headache Impact Test-6 (HIT-6), Tampa Scale for Kinesiophobia for Temporomandibular Disorders-12 (TSK-TMD-12), Pain Catastrophizing Scale (PCS), Neck Disability Index (NDI), Fonseca Anamnestic Index (FAI), and Jaw Functional Limitation Scale-20 (JFLS-20). Correlations ranging from low to high were expected. RESULTS CF-PDI/T showed excellent test-retest reliability (ICC = 0.971), excellent internal consistency (Cronbach's α = 0.985), and low to high correlation with NRS, HIT-6, TSK-TMD, PCS, NDI, FAI, and JFLS-20. Following EFA, three factors ("pain and psychosocial limitation", "jaw functional status", and "frequency comorbidities and disability") were extracted, accounting for 55.028% of the total variation. CONCLUSIONS The CF-PDI/T is a reliable and valid instrument to assess the symptoms and disability in the Turkish population with temporomandibular disorders. Clinical trial registration number: NCT03837587.Implications for rehabilitationThe Spanish version of the Craniofacial Pain and Disability Inventory is a highly reliable and good valid outcome measure to evaluate disability and treatment outcomes for individuals with temporomandibular disorders (TMDs).We suggest the Turkish version of the Craniofacial Pain and Disability Inventory (CF-PDI/T) be used in the Turkish population to indicate small changes in the severity of disorder of individuals with TMDs until a normal quality of life is achieved.The CF-PDI/T can be used with high reliability and validity by experienced and inexperienced dentists and physiotherapists.

Effectiveness of Physiotherapy in the Treatment of Temporomandibular Joint Dysfunction and the Relationship with Cervical Spine. Biomedicines 2022; 10:biomedicines10112962. [PMID: 36428529 PMCID: PMC9687864 DOI: 10.3390/biomedicines10112962] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/11/2022] [Accepted: 11/14/2022] [Indexed: 11/19/2022] Open
Abstract
Temporomandibular dysfunctions are a heterogeneous group of conditions involving the temporomandibular joints (TMJs) and periarticular musculoskeletal structures. This study aimed to evaluate the effectiveness of a physiotherapy program for TMJ dysfunctions and the relationship with cervical spine. The study design was a non-randomized clinical trial with two parallel treatment groups: 33 subjects in the experimental group that underwent conservative drug treatment and physiotherapy treatment, and 31 subjects in the control group that underwent only conservative drug treatment. The participants were examined at baseline and re-examined after 3 months. In this study there was a higher incidence of female subjects. After 3 months of treatment of the TMJs and cervical spine, pain decreased in both groups (p = 0001). Muscle testing at the cervical spine and temporomandibular level showed a decrease in pain and muscles spasms. The average percentage values of the Neck Disability Index (NDI) and the Jaw Functional Limitation Scale 8 (JFLS 8) decreased significantly in both groups, but especially in the experimental group (p = 0.001). Physiotherapy treatments could maintain the functional state at the temporomandibular and cervical levels, thus contributing to increasing the quality of daily life.

Abstract
BACKGROUND Otological complaints (OC) are highly prevalent in subjects with temporomandibular disorders (TMD) and so is the risk of neck dysfunctions. OBJECTIVE To evaluate pain, deep neck flexor (DNF) performance, disability, and head and neck posture of individuals with TMD with and without OC. METHODS In this cross-sectional study, 57 individuals were divided into a group with TMD and OC (n= 31) and a group with TMD without OC (n= 26). Self-reported pain intensity, masticatory and neck muscles pressure pain thresholds, DNF performance, neck disability, and head and neck posture were evaluated. Data were compared between groups using the independent t test and Mann-Whitney test with Bonferroni correction for multiple comparisons. Effect sizes were evaluated using Cohen's index. RESULTS The TMD with OC group presented less muscle activation [26 (24-28) vs. 24 (24-26) mmHg; p< 0.05], less endurance [105 (46-140) vs. 44 (28-78) points; p< 0.05], and greater neck disability (8.15 ± 5.89 vs. 13.32 ± 6.36 points; p< 0.05). No significant difference was observed in self-reported pain, head and neck posture, or pressure pain thresholds. CONCLUSION Individuals with TMD with OC presented decreased DNF performance and increased neck disability compared to individuals with TMD without OC.

Abstract
Temporomandibular disorder (TMD) is recognized for its high prevalence, presenting characteristic signs and symptoms. Cervical spine pain is present in 70% of diagnosed TMD cases. Aim: To verify if women with TMD present changes in isometric muscle strength in the scapula elevation. Methods: This is an observational, cross-sectional study. Thirty-five women, aged 22.89±2.04 years, were divided into the TMD group (TMDG), diagnosed with TMD according to the DC/TMD, and control group (CG), with asymptomatic individuals. The volunteers accessed a online link by the smartphone in order to answer questions on personal data, the Fonseca Anamnestic Index (FAI), Neck Disability Index (NDI), and Masticatory preference. In all participants, evaluation of the force of the scapula elevation muscles was performed, using a load cell model MM-100 (Kratos® SP, Brazil). Data were analyzed descriptively using the maximum, mean, and standard deviation and a two-way ANCOVA test was applied for all variables. A significance level of 5% was considered. Results: There were no statistically significant differences between the TMDG and CG for the maximal and mean muscle strength of scapular elevation. There were statistically significant differences in FAI (p <0.001*) between the CG and the TMDG. Conclusion: Based on the results, it was not possible to confirm the hypothesis that women diagnosed with TMD present lower isometric strength during scapular elevation (right/left).

Abstract
OBJECTIVE To evaluate neck pain, disability, and deep neck flexor (DNF) performance of individuals with temporomandibular disorders (TMD). METHODS Eighty individuals were divided into the following: arthrogenic TMD (n = 40), myogenic TMD (n = 12), and mixed TMD (n = 28). Neck pain intensity, neck disability, and DNF performance were evaluated. RESULTS Individuals with arthrogenic TMD reported lower intensity of neck pain when compared to mixed TMD (p = 0.01). Individuals with arthrogenic TMD had less neck disability than individuals with myogenic TMD (p = 0.037) and mixed TMD (p < 0.001). A moderate positive correlation was found between neck pain and neck disability (p < 0.001). No differences were found for DNF performance. CONCLUSION Neck pain and disability differs according to subtype of TMD, but performance of the deep neck flexors does not. Neck pain intensity and neck disability were correlated in patients with TMD.

Abstract
ObjectiveTo evaluate whether a single specific motor control training session for the neck flexor and deep extensor muscles improves upper cervical range of motion and neck motor control in patients with temporomandibular disorder (TMD) and compare them to a group without TMD. MethodsThis is a before and after, controlled study. The TMD group included women aged between 18-45 years old, complaining of pain in the orofacial region in the last 6 months and diagnosed with masticatory myofascial pain according to Research Diagnostic Criteria (RDC/MD). The control group included match-controls without TMD. The participants were evaluated to global and upper (Flexion Rotation Test - FRT) neck range of motion (ROM) and to neck motor control (Cranio-Cervical Flexion Test - CCFT). They were treated with a protocol of specific motor control exercises targeted to flexor and extensor neck muscles for 30 minutes. One day after the protocol the patients were reevaluated. ResultsA total of 23 volunteers were evaluated. The TMD group showed immediate improvement in left cervical rotation (p=0.043) and right FRT (p=0.036), while the control group did not show any improvement. There was no difference between the groups before and after treatment in relation to cervical movements. Regarding cervical motor control in both groups, the highest prevalence was of results between 24 and 26 mmHg after treatment, different from before the intervention (20 and 22 mmHg) in both groups.ConclusionA single session of specific neck motor control training only improved the left cervical rotation and upper right rotation in the TMD group, but not in the control group. There is no difference at the end of treatment between the groups. Volunteers with TMD showed improvement in the pattern of motor control of the neck when compared to volunteers without TMD.

Skeletal Divergence and Condylar Asymmetry in Patients with Temporomandibular Disorders (TMD): A Retrospective Study. BIOMED RESEARCH INTERNATIONAL 2021; 2021:8042910. [PMID: 34608439 PMCID: PMC8487372 DOI: 10.1155/2021/8042910] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 06/16/2021] [Accepted: 09/03/2021] [Indexed: 01/08/2023]
Abstract
Introduction This study was aimed at evaluating the association between vertical skeletal patterns, condylar height symmetry, and temporomandibular disorders in adults. Methods The study sample consisted of 200 patients (ages 18-30 years old) retrospectively recruited: 100 with temporomandibular disorders (TMD) and 100 without TMD (control), diagnosed by Diagnostic Criteria for the Temporomandibular Disorders (DC/TMD). For each subject, skeletal divergence was assessed on lateral cephalograms, and condylar height symmetry was evaluated by orthopantomography (Habets' method). Results Subjects with temporomandibular disorders showed a strong association with condylar asymmetry (p < 0.0001) and, for the skeletal pattern variables, hyperdivergence (p < 0.001). A correlation with the female sex was also found (p < 0.04), while there was no difference in terms of age in the 2 groups (p > 0.29). Conclusions Although it does not imply a direct cause-and-effect relationship, the present study suggests condylar asymmetry and hyperdivergent skeletal pattern are more likely to be associated with a higher risk of temporomandibular disorder joint diseases in adult patients.

Abstract
OBJECTIVE To identify assessment tools used to evaluate patients with temporomandibular disorders (TMD) considered to be clinically most useful by a panel of international experts in TMD physical therapy (PT). METHODS A Delphi survey method administered to a panel of international experts in TMD PT was conducted over three rounds from October 2017 to June 2018. The initial contact was made by email. Participation was voluntary. An e-survey, according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), was posted using SurveyMonkey for each round. Percentages of responses were analysed for each question from each round of the Delphi survey administrations. RESULTS Twenty-three experts (completion rate: 23/25) completed all three rounds of the survey for three clinical test categories: 1) questionnaires, 2) pain screening tools and 3) physical examination tests. The following was the consensus-based decision regarding the identification of the clinically most useful assessments. (1) Four of 9 questionnaires were identified: Jaw Functional Limitation (JFL-8), Mandibular Function Impairment Questionnaire (MFIQ), Tampa Scale for Kinesiophobia for Temporomandibular disorders (TSK/TMD) and the neck disability index (NDI). (2) Three of 8 identified pain screening tests: visual analog scale (VAS), numeric pain rating scale (NRS) and pain during mandibular movements. (3) Eight of 18 identified physical examination tests: physiological temporomandibular joint (TMJ) movements, trigger point (TrP) palpation of the masticatory muscles, TrP palpation away from the masticatory system, accessory movements, articular palpation, noise detection during movement, manual screening of the cervical spine and the Neck Flexor Muscle Endurance Test. CONCLUSION After three rounds in this Delphi survey, the results of the most used assessment tools by TMD PT experts were established. They proved to be founded on test construct, test psychometric properties (reliability/validity) and expert preference for test clusters. A concordance with the screening tools of the diagnostic criteria of TMD consortium was noted. Findings may be used to guide policymaking purposes and future diagnostic research.

Abstract
BACKGROUND Studies have shown co-contraction of jaw and neck muscles in healthy subjects during (sub) maximum voluntary jaw clenching, indicating functional inter-relation between these muscles during awake bruxism. So far, coherence of jaw and neck muscles has not been evaluated during either awake or sleep bruxism. OBJECTIVE The objective of this study was to evaluate the coherence between jaw and neck muscle activity during sleep bruxism. METHODS In a cross-sectional observational design, the electromyographic activity of jaw (masseter, temporalis) and neck (sternocleidomastoid, trapezius) muscles in individuals with "definite" sleep bruxism was measured using ambulatory polysomnography (PSG). Coherence for masseter-temporalis, masseter-sternocleidomastoid and masseter-trapezius was measured during phasic and mixed rhythmic masticatory muscle activity episodes using coherence-analysing software. Outcome measures were as follows: presence or absence of significant coherence per episode (in percentages), frequency of peak coherence (FPC) per episode and sleep stage. RESULTS A total of 632 episodes within 16 PSGs of eight individuals were analysed. Significant coherence was found between the jaw and neck muscles in 84.9% of the episodes. FPCs of masseter-temporalis were significantly positively correlated with those of masseter-sternocleidomastoid or masseter-trapezius (P < .001). Sleep stages did not significantly influence coherence of these muscular couples. CONCLUSION During sleep bruxism, jaw and neck muscle activation is significantly coherent. Coherence occurs independently of sleep stage. These results support the hypothesis of bruxism being a centrally regulated phenomenon.

Abstract
Objective: The purpose of this study was to investigate the aerobic capacity in patients with temporomandibular dysfunction (TMD) and to compare the results with those of the asymptomatic individuals.Methods: The TMD group included a total of 31 females between the ages of 18 and 25 years. The control group consisted of 31 asymptomatic females with an age range of 18 to 27 years. A graded exercise test was performed using an electronically braked arm crank ergometer. An indirect calorimeter system was used to calculate the peak oxygen consumption (VO2peak). In addition, peak heart rate (HRpeak) and respiratory quotient were calculated for each participant.Results: The TMD group had lower VO2peak (p = 0.017) and HRpeak (p = 0.012) in aerobic capacity tests; however, respiratory quotient was similar in both groups (p = 0.446).Discussion: The TMD group had lower aerobic capacity compared to the asymptomatic individuals.

Abstract
PURPOSE Bruxism is highly prevalent and defined as abnormal habitual mouth activity including clenching of the teeth and increased jaw muscle activity. The association between bruxism and temporomandibular dysfunction (TMD) is debated, in particular the association between cervical spine impairments, bruxism, and TMD. Hence the purpose of this study was to identify the relationship between bruxism, TMD, and cervical spine impairments. METHODS This observational study categorized 55 female volunteers suitable for evaluation to a bruxism (n = 33) or non-bruxism group (n = 22) based on comprehensive screening using questionnaires and visual observation of the mouth by 2 independent dentists. Following this, both groups were evaluated for TMD, severity and location of head/neck pain, neck disability index (NDI), cervical spine impairments, and tissue mechanosensitivity. Regression analysis was used to evaluate the relationship between bruxism, TMD severity, and cervical impairments. RESULTS Coefficients of pain and bruxism were significantly associated with NDI scores (0.43, p < 0.001; 3.24, p = 0.01) with large and medium sized effects. As a consequence, both severity of TMD and bruxism status are independently associated with cervical impairments. Having TMD is an independent predictor for head/neck pain and cervical impairments. Pain associated with movement tests and tissue mechanosensitivity was found to be an important factor in bruxism. CONCLUSION Clinicians need to be aware that signs of cervical movement impairment are not likely to be associated with bruxism, rather they should focus on improving orofacial function and tissue mechanosensitivity.

Abstract
BACKGROUND The International Classification of Headache Disorders, 3rd Edition, accepted "headache attributed to temporomandibular disorders" as a valid headache. The neurophysiologic interplay between cervical structures and the temporomandibular joint, however, might also suggest that a temporomandibular disorder could develop in patients with cervicogenic headache. OBJECTIVE To compare the presence of preclinical temporomandibular signs between female patients with episodic cervicogenic headache and a control group. DESIGN Case-controlled cross-sectional design. SETTING Institutional setting: Hasselt University. PARTICIPANTS Twenty-two women (mean age ± SD: 20.7 ± 2.5 years) with episodic cervicogenic headache, without temporomandibular signs and 22 matched (gender, age, level of education, occupation) asymptomatic controls (21 ± 2.3 years). METHODS (Un)assisted temporomandibular range of motion, pressure pain thresholds, painful palpations were examined and the level of perceived stress was measured. MAIN OUTCOME MEASUREMENTS Temporomandibular range of motion (mm), pressure pain thresholds (kPa/cm²), painful palpations (yes/no), and level of perceived stress (Perceived Stress Scale). RESULTS Maximal mouth-opening was significantly smaller in the headache group (P <.05; effect size [ES] -0.45). Palpation of the masseter resulted in significantly more positive pain responses in the headache group at the left (P = .009; ES ∞) and right (P = .002;ES 17.5) origin, left (P = .004; ES 14.54) and right (P = .03; ES 5.71) body and left (P < .001; ES 12) insertion. Significantly lower pressure pain thresholds on the left and right anterior (P = .03; ES -0.33 resp. P = .02; ES -0.35), central (P = .003; ES 1.02 resp. P = .02; ES 0.79) and right posterior (P = .03; ES 0.62) temporalis and right tibialis anterior (P = .03; ES -0.33) were measured in the headache group. The level of perceived stress was significantly higher (P = .02) in the headache group. CONCLUSIONS Patients with episodic cervicogenic headache present with signs of a preclinical temporomandibular disorder and sensitization. The smaller range of motion, lower pressure pain thresholds, and higher levels of stress accentuate the multidimensionality of the problem. LEVEL OF EVIDENCE IV.

Abstract
Cervicogenic headache is a relatively common but unique form of headache, and in China, as well as in several other countries, both diagnosis and a clear evidence-based treatment plan remain controversial. Therefore, the Chinese Association for the Study of Pain organized a meeting of pain management experts and created an expert consensus on the diagnosis and treatment of cervicogenic headache in China. This article summarizes the conclusions of the consensus group regarding the epidemiology, etiology, clinical features, diagnosis, differential diagnosis, treatment, and rehabilitation of cervicogenic headache in China.

Abstract
The primary objective of this study was to determine the structural and known-group validity as well as the inter-rater reliability of a test battery to evaluate the motor control of the craniofacial region. Seventy volunteers without TMD and 25 subjects with TMD (Axes I) per the DC/TMD were asked to execute a test battery consisting of eight tests. The tests were video-taped in the same sequence in a standardised manner. Two experienced physical therapists participated in this study as blinded assessors. We used exploratory factor analysis to identify the underlying component structure of the eight tests. Internal consistency (Cronbach's α), inter-rater reliability (intra-class correlation coefficient) and construct validity (ie, hypothesis testing-known-group validity) (receiver operating curves) were also explored for the test battery. The structural validity showed the presence of one factor underlying the construct of the test battery. The internal consistency was excellent (0.90) as well as the inter-rater reliability. All values of reliability were close to 0.9 or above indicating very high inter-rater reliability. The area under the curve (AUC) was 0.93 for rater 1 and 0.94 for rater two, respectively, indicating excellent discrimination between subjects with TMD and healthy controls. The results of the present study support the psychometric properties of test battery to measure motor control of the craniofacial region when evaluated through videotaping. This test battery could be used to differentiate between healthy subjects and subjects with musculoskeletal impairments in the cervical and oro-facial regions. In addition, this test battery could be used to assess the effectiveness of management strategies in the craniofacial region.

Therapeutic Evaluation of Cervical Dysfunction in Patients with Myofascial Pain Dysfunction Syndrome: A Prospective Study. J Contemp Dent Pract 2017; 18:601-606. [PMID: 28713116 DOI: 10.5005/jp-journals-10024-2092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/23/2022]
Abstract
AIM The aim of this study was to find out the therapeutic correlation between cervical dysfunction and myofascial pain dysfunction syndrome (MPDS). MATERIALS AND METHODS The study included 46 patients out of which 23 had MPDS with cervical pain (group I), and 23 patients had only MPDS (group II). Detailed history and examination of the patients were carried out, and the factors taken into consideration were pain and tenderness of muscles of mastication and neck muscles, maximum comfortable mouth opening, and cervical range of motion. All the patients were randomly divided and advised physical exercises, light amplification by stimulated emission of radiation (LASER) therapy, and the combination of both exercise and LASER. Patients were assessed for the relief of signs and symptoms of myofascial pain and cervical pain posttreatment, every month for 2 months. RESULTS Both the groups showed a similar response to all the different treatment modalities. In group I, the patients also had relief in their cervical pain although the treatment was directed for MPDS. Patients from both the groups who were advised LASER and combination of both exercise and LASER showed better response in terms of reduction in visual analog scale, number of tender muscles, and increased maximum comfortable mouth opening posttreatment and during the follow-up, as compared with the patients who were advised only exercise. CONCLUSION Patients having cervical pain showed significant improvement comparable with patients having no cervical pain. Hence, the conclusion drawn was that there is a positive interrelationship between MPDS and cervical (neck) pain; MPDS may act as a catalyst for precipitating cervical pain. CLINICAL SIGNIFICANCE Cervical pain showed significant improvement to physiotherapy in the form of exercise, LASER, and combination treatment, though the effective modality was LASER and combination of exercise and LASER therapy.

Effects of cervical mobilization and exercise on pain, movement and function in subjects with temporomandibular disorders: a single group pre-post test. J Appl Oral Sci 2016; 24:188-97. [PMID: 27383698 PMCID: PMC5022215 DOI: 10.1590/1678-775720150240] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2015] [Accepted: 03/09/2016] [Indexed: 11/24/2022] Open
Abstract
Objective To investigate the effect of a rehabilitation program based on cervical mobilization and exercise on clinical signs and mandibular function in subjects with temporomandibular disorder (TMD). Material and Methods: Single-group pre-post test, with baseline comparison. Subjects Twelve women (22.08±2.23 years) with myofascial pain and mixed TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders. Outcome measures Subjects were evaluated three times: twice before (baseline phase) and once after intervention. Self-reported pain, jaw function [according to the Mandibular Functional Impairment Questionnaire (MFIQ)], pain-free maximum mouth opening (MMO), and pressure pain thresholds (PPTs) of both masseter and temporalis muscles were obtained. Baseline and post-intervention differences were investigated, and effect size was estimated through Cohen’s d coefficient. Results Jaw function improved 7 points on the scale after the intervention (P=0.019), and self-reported pain was significantly reduced (P=0.009). Pain-free MMO varied from 32.3±8.8 mm to 38±8.8 mm and showed significant improvement (P=0.017) with moderate effect size when compared to the baseline phase. PPT also increased with moderate effect size, and subjects had the baseline values changed from 1.23±0.2 kg/cm2 to 1.4±0.2 kg/cm2 in the left masseter (P=0.03), from 1.31±0.28 kg/cm2 to 1.51±0.2 kg/cm2 in the right masseter (P>0.05), from 1.32±0.2 kg/cm2 to 1.46±0.2 kg/cm2 in the left temporalis (P=0.047), and from 1.4±0.2 kg/cm2 to 1.67±0.3 kg/cm2 in the right temporalis (P=0.06). Conclusions The protocol caused significant changes in pain-free MMO, self-reported pain, and functionality of the stomatognathic system in subjects with myofascial TMD, regardless of joint involvement. Even though these differences are statistically significant, their clinical relevance is still questionable.

Abstract
Temporomandibular disorder (TMD) is a common condition that can be difficult to manage in physical therapy. A number of interventions, such as manual therapy, therapeutic exercise, and patient education have typically been used in some combination. However, the evidence regarding thrust manipulation of not only the local but also adjacent segments is sparse. Specifically, the use of cervicothoracic (CT) junction thrust manipulation has not previously been described in the management of individuals with TMD. In this case report, CT junction thrust manipulation, in addition to locally directed manual therapy, exercise, and postural education, was associated with immediate improvements in neck and jaw symptoms and function in a complex patient with TMD. The patient was seen for seven visits over the course of 2 months and demonstrated clinically significant changes in the neck disability index (NDI), the numeric rating of pain scale (NPRS), and the global rating of change (GROC) scale. The purpose of this report is to describe the successful physical therapy management of a patient with TMD utilizing manual therapy, including CT junction thrust manipulation, education, and exercise.

Abstract
Objectives This study investigated the association between craniofacial morphology and temporomandibular disorders in adults. The influence of different craniofacial morphologies on painful temporomandibular disorders was also evaluated. Material and Methods A total of 200 subjects were selected, including 100 with temporomandibular disorders (TMD) and 100 without TMD (control), diagnosed by research diagnostic criteria for temporomandibular disorders. All subjects were submitted to lateral cephalometric radiographs, and classified as brachyfacial, mesofacial, or dolichofacial by Ricketts’ analysis. Data were analysed by Tukey-Kramer and Chi-square tests. Results No association between craniofacial morphology and TMD was found (P = 0.6622). However, brachyfacial morphology influences the presence of painful TMD (P = 0.0077). Conclusions Craniofacial morphology is not related to temporomandibular disorders in general.

Abstract
Objectives This cross-sectional correlation study explored the relationships between craniocervical posture and pain-related disability in patients with chronic cervico-craniofacial pain (CCFP). Moreover, we investigated the test–retest intrarater reliability of two craniocervical posture measurements: head posture (HP) and the sternomental distance (SMD). Methods Fifty-three asymptomatic subjects and 60 CCFP patients were recruited. One rater measured HP and the SMD using a cervical range of motion device and a digital caliper, respectively. The Spanish versions of the neck disability index and the craniofacial pain and disability inventory were used to assess pain-related disability (neck disability and craniofacial disability, respectively). Results We found no statistically significant correlations between craniocervical posture and pain-related disability variables (HP and neck disability [r=0.105; P>0.05]; HP and craniofacial disability [r=0.132; P>0.05]; SMD and neck disability [r=0.126; P>0.05]; SMD and craniofacial disability [r=0.195; P>0.05]). A moderate positive correlation was observed between HP and SMD for both groups (asymptomatic subjects, r=0.447; CCFP patients, r=0.52). Neck disability was strongly positively correlated with craniofacial disability (r=0.79; P<0.001). The test–retest intrarater reliability of the HP measurement was high for asymptomatic subjects and CCFP patients (intraclass correlation coefficients =0.93 and 0.81, respectively) and for SMD (intra-class correlation coefficient range between 0.76 and 0.99); the test–retest intrarater reliability remained high when evaluated 9 days later. The HP standard error of measurement range was 0.54–0.75 cm, and the minimal detectable change was 1.27–1.74 cm. The SMD standard error of measurement was 2.75–6.24 mm, and the minimal detectable change was 6.42–14.55 mm. Independent t-tests showed statistically significant differences between the asymptomatic individuals and CCFP patients for measures of craniocervical posture, but these differences were very small (mean difference =1.44 cm for HP; 6.24 mm for SMD). The effect sizes reached by these values were estimated to be small for SMD (d=0.38) and medium for HP (d=0.76). Conclusion The results showed no statistically significant correlations between craniocervical posture and variables of pain-related disability, but a strong correlation between the two variables of disability was found. Our findings suggest that small differences between CCFP patients and asymptomatic subjects exist with respect to the two measurements used to assess craniocervical posture (HP and SMD), and these measures demonstrated high test–retest intrarater reliability for both CCFP patients and asymptomatic subjects.

The effects of mouth opening on changes in the thickness of deep cervical flexors in normal adults. J Phys Ther Sci 2015; 27:239-41. [PMID: 25642082 PMCID: PMC4305572 DOI: 10.1589/jpts.27.239] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2014] [Accepted: 08/15/2014] [Indexed: 11/24/2022] Open
Abstract
[Purpose] The purpose of this study was to identify changes in the thickness of the deep
cervical flexors (DCFs) according to the degree of mouth opening (MO) in normal adults.
[Subjects] The study’s subjects were 50 normal adults (30 men, 20 women). [Methods]
Ultrasound was used to obtain images of muscles, and the NIH ImageJ software was used to
measure the thickness of each muscle. [Results] An increase in MO resulted in a
corresponding increase in the thickness of the DCFs, and in isometric exercises (IEs), the
thickness of the DCFs further increased during MO. [Conclusion] During MO, the thickness
of the DCFs increased. This may be due to correlations between mandibular movements and
DCFs. Therefore, the results are likely to be utilized as new clinical research data.
