Validation of the Portuguese Version of the Kansas City Cardiomyopathy Questionnaire-12.

The Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) is a simple, feasible, and sensitive questionnaire developed in English for assessing the health status (symptoms, function, and quality of life) of patients with heart failure (HF). We aimed to assess the internal consistency and construct validity of the Portuguese version of KCCQ-12. We administered the KCCQ-12, the Minnesota Living Heart Failure (MLHFQ), and the New York Heart Association (NYHA) classification by telephone. Internal consistency was assessed with Cronbach's Alpha (α-Cronbach) and construct validity with correlations to the MLHFQ and NYHA. Internal consistency was high (α-Cronbach = 0.92 for the Overall Summary score and 0.77-0.85 for the subdomains). Construct validity was supported by finding high correlations between the KCCQ-12 Physical Limitation and the Symptom Frequency domains with the physical domain of the MLHFQ (r = -0.70 and r = -0.76, p < 0.001 for both) and the Overall Summary scale with NYHA classifications (r = -0.72, p < 0.001). The Portuguese version of KCCQ-12 has high internal consistency and shows a convergent construct validity with other measures quantifying the health status of patients with chronic HF and can be used confidently in Brazil for research and clinical care.

Hypoalgesic Effects of Transcutaneous Electrical Nerve Stimulation Combined With Joint Manipulation: A Randomized Clinical Trial.

OBJECTIVE: The objective of this study was to compare the hypoalgesic effects of isolated or combined use of transcutaneous electrical nerve stimulation (TENS) and cervical joint manipulation (JM) in asymptomatic participants. METHODS: One hundred and forty-four healthy participants aged 18 to 30 years old were randomly assigned to 1 of 4 groups (n = 36 per group): active TENS + active JM, active TENS + placebo JM, placebo TENS + active JM, and placebo TENS + placebo JM. Active or placebo TENS was applied to the dominant forearm. JM was applied to the C6-7 segments. The pressure pain threshold was measured pre- and postintervention and after 20 minutes on the forearm and tibialis anterior of the dominant side. RESULTS: Segmental hypoalgesia was greater in the group active TENS + active JM compared with active TENS + placebo JM (P = .002), placebo TENS + active JM (P < .0001), and placebo TENS + placebo JM (P < .0001). For the extrasegmental hypoalgesia, active TENS + active JM had greater hypoalgesic effect compared with active TENS + placebo JM (P = .033), placebo TENS + active JM (P = .002), and placebo TENS + placebo JM (P < .0001). CONCLUSION: TENS and JM produced hypoalgesia when used alone and, when the treatments were combined, a higher segmental and extrasegmental hypoalgesic effect was obtained in asymptomatic participants.

Immediate effects of upper thoracic manipulation on the skin surface temperature of the vertebral region in healthy women / Efeitos imediatos da manipulação torácica alta sobre a temperatura superficial cutânea da região vertebral em mulheres saudáveis / Los efectos inmediatos de la alta manipulación torácica de la temperatura superficial de la piel en la región vertebral en mujeres sanas

Manipulation of the spinal column is a manual therapeutic resource characterized by passive thrust of a given joint at a high velocity and low amplitude within the limits of anatomic integrity. The objective of the present study was to assess the immediate effects of upper thoracic manipulation on skin temperature in the vertebral region in healthy women. Thus, a randomized controlled blind trial was realized in the university community. Twenty-six healthy women were randomly allocated into an experimental group (n=13) and a placebo group (n=13). A single session of upper thoracic spine manipulation (segment T3) was performed. Infrared thermography was used to determine changes in skin temperature in the vertebral region. Images were taken prior to, immediately after and both five and 10 minutes after manipulation. Two-way repeated measures analysis of variance with post hoc Bonferroni test was used for inter and intragroup comparisons. The level of significance was set to 5%. No significant differences were found between the different evaluation times in either group (p>0.05). In the intergroup analysis, no statistically significant differences were found in any of the comparisons (p>0.05). Based on the method employed, thoracic spine manipulation of the T3 vertebral segment does not promote changes in skin surface temperature in the region manipulated in asymptomatic individuals.

Women with more severe degrees of temporomandibular disorder exhibit an increase in temperature over the temporomandibular joint.

AIM: The purpose of the present study was to correlate the degree of temporomandibular disorder (TMD) severity and skin temperatures over the temporomandibular joint (TMJ) and masseter and anterior temporalis muscles. MATERIALS AND METHODS: This blind cross-sectional study involved 60 women aged 18-40 years. The volunteers were allocated to groups based on Fonseca anamnestic index (FAI) score: no TMD, mild TMD, moderate TMD, and severe TMD (n = 15 each). All volunteers underwent infrared thermography for the determination of skin temperatures over the TMJ, masseter and anterior temporalis muscles. The Shapiro-Wilk test was used to determine the normality of the data. The Kruskal-Wallis test, followed by Dunn's test, was used for comparisons among groups according to TMD severity. Spearman's correlation coefficients were calculated to determine the strength of associations among variables. RESULTS: Weak, positive, significant associations were found between FAI score and skin temperatures over the left TMJ (rs = 0.195, p = 0.009) and right TMJ (rs = 0.238, p = 0.001). Temperatures over the right and left TMJ were significantly higher in groups with more severe TMD (p < 0.05). CONCLUSION: FAI score was associated with skin temperature over the TMJ, as determined by infrared thermography, in this sample. Women with more severe TMD demonstrated a bilateral increase in skin temperature.

The chronicity of myogenous temporomandibular disorder changes the skin temperature over the anterior temporalis muscle.

The aim of the present study was to investigate the correlation between the chronicity of myogenous temporomandibular disorder (TMD) and skin temperature over the masseter and anterior temporalis muscles. A blind, cross-sectional study was carried out involving 30 women with myogenous TMD, aged 18-40 years (mean of 23.60 ± 5.12 years). The volunteers were recruited from the university community. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was used for the diagnosis of TMD and the determination of chronicity. The volunteers were also submitted to infrared thermography to measure absolute skin temperature over the masseter and anterior temporalis muscles and determine their temperature asymmetries. A significant association was found between duration of TMD and temperature asymmetry of the anterior temporalis muscle (rs = 0.224, p = 0.034). The present findings demonstrate that chronicity of myogenous TMD changes the skin temperature over the anterior temporalis muscle.

Accuracy of two forms of infrared image analysis of the masticatory muscles in the diagnosis of myogenous temporomandibular disorder.

The aim of the present study was to assess the accuracy of two forms of infrared image analysis (area and extension) of the masseter and anterior temporalis muscles in the diagnosis of myogenous temporomandibular disorder (TMD). A cross-sectional study was carried out involving 104 female volunteers from the university community. Following the application of the Research Diagnostic Criteria for Temporomandibular Disorders, the volunteers were divided into a TMD group (n = 52) and control group (n = 52), and evaluated using infrared thermography. The area and extension of the masseter and anterior temporalis muscles were measured on the images. The receiver operating characteristic (ROC) curve was used to determine diagnostic accuracy (area under the curve), best cutoff point, sensitivity and specificity. A significant difference in skin temperature between groups was only found in the measurement of the area of the left anterior temporalis muscle (p = 0.011). The area under the ROC curve was less than the reference values for all muscles evaluated in the analyses of area and extension. Thus, neither method of infrared thermography tested for the quantification of the masseter and anterior temporalis muscles (analysis of area and extension) is consistent with the RDC/TMD for the diagnosis of myogenous TMD in women.

Correlation between skin surface temperature over masticatory muscles and pain intensity in women with myogenous temporomandibular disorder.

BACKGROUND AND OBJECTIVE: Pain is a common clinical manifestation in individuals with temporomandibular disorder (TMD). The literature report changes in microcirculation in this condition. The aim of the present study was to correlate skin surface temperature at the central point of the masticatory muscles with pain intensity in women with myogenous TMD. MATERIALS AND METHODS: The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and the visual analogue scale (VAS) were used to divide 40 female university students into four groups: control group (n=10), mild pain group (n=10), moderate pain group (n=10) and severe pain group (n=10). Infrared thermography was used to assess the masticatory muscles. RESULTS: No significant correlations were found between pain intensity and skin surface temperature over the left masseter (p=0.368), right masseter (p=0.618), left anterior temporalis (p=0.293) and right anterior temporalis (p=0.922) muscles. No correlations were found between pain intensity and asymmetry of the masseter (p=0.375) and anterior temporalis (p=0.090) muscles. Moreover, no significant difference in skin surface temperature (p> 0.05) was found among the different groups. CONCLUSION: Pain intensity in women with myogenous TMD was not associated with skin surface temperature at the central point of the masseter and anterior temporalis muscles.

Accuracy and reliability of infrared thermography in the diagnosis of arthralgia in women with temporomandibular disorder.

OBJECTIVE: The purpose of this study was to determine the accuracy and reliability of infrared thermography in the diagnosis of arthralgia in women with temporomandibular disorder. METHODS: Thirty women aged between 18 and 40 years were recruited for the study. The Research Diagnostic Criteria for Temporomandibular Disorders was used to allocate the volunteers to the control group (n = 15) and arthralgia group (n = 15). Both groups were submitted to infrared thermography of the temporomandibular joint (TMJ), followed by a punctual analysis of the images. The Mann-Whitney U test was used for the comparison of skin surface temperature between groups. The intraclass correlation coefficient was calculated to determine the reliability of the infrared image analysis. The receiver operating characteristic curve was used to determine the accuracy of the diagnosis. RESULTS: Skin temperature was significantly greater over the left (P = .004) and right (P = .012) TMJ in the arthralgia group. The intraclass correlation coefficient ranged from 0.841 to 0.874. The area under the receiver operating characteristic curve ranged from 0.598 to 0.675. CONCLUSION: Excellent intrarater and interrater reliability was found in the analysis of the infrared images of the TMJ. However, infrared thermography demonstrated a low accuracy in the diagnosis of arthralgia in women with temporomandibular disorder.

Accuracy of infrared thermography of the masticatory muscles for the diagnosis of myogenous temporomandibular disorder.

OBJECTIVE: The purpose of this study was to evaluate the accuracy of infrared thermography of the central point of the masseter and anterior temporalis muscles for the diagnosis of myogenous temporomandibular disorder (TMD). METHODS: This is an observational study of university women with and without TMD. Through the use of the Research Diagnostic Criteria for Temporomandibular Disorders, 104 women were divided into a TMD group (n = 52) and control group (n = 52). All volunteers had their masseter and anterior temporalis muscles evaluated by infrared thermography. The receiver operating characteristic (ROC) curve was used to determine the accuracy of diagnosis (area under the ROC curve), the best cut-off point, sensitivity, and specificity. RESULTS: No significant differences were observed (P > .05) in the skin surface temperature of the masticatory muscles, when the groups were compared. With regard to the ROC curve, the area under the curve was lower than the recommended for all the muscles tested, ranging from 0.433 to 0.502. CONCLUSION: The findings of this study suggest that infrared thermography of the masticatory muscles is not an accurate instrument for the myogenous TMD diagnosis.

Assessment of the upper trapezius muscle temperature in women with and without neck pain.

OBJECTIVE: The purpose of the study was to analyze the upper trapezius muscle temperature using thermography in women with and without neck pain. METHODS: Thirty-six female university students were classified through the Neck Disability Index (NDI) into 2 groups: the neck pain group comprised 18 volunteers diagnosed with mild disability, and the control group, 18 healthy volunteers. All subjects were submitted to evaluation by thermography, which registered the skin surface temperature of the upper bilateral trapezius muscle. Student t test and Mann-Whitney U test were used for the comparison between the groups, and the Spearman correlation coefficient was used for the appropriate correlations between the NDI score and the temperature values. A significance level of 5% was set. RESULTS: No significant difference was found between the groups regarding the temperature values of the upper left (P = .565) and right (P = .917) trapezius muscles, as well as in comparisons of temperature asymmetry (P = .542). In addition, no significant association was found between the study variables (P > .05). CONCLUSION: Women with neck pain, diagnosed with mild disability by NDI, did not present with reduction or asymmetry of upper trapezius muscle temperature when compared with a group without neck pain.
