Abstract Recently, the DC/TMD has become an essential tool for the diagnosis of temporomandibular disorders (TMD). However, as they fail to include functional activities, new assessment proposals have emerged, such as the isometric contraction test (IC test) of the masticatory muscles, which uses muscle contractions to identify muscular TMD. Objective This study aimed to determine the test-retest reliability of the IC test. Methods A total of 64 participants (40 women and 24 men) completed the IC test administered by two different physical therapists on two non-consecutive days. Cohen’s kappa (k), PABAK, and percent agreement (PA) between days were estimated. Results The IC test showed good to excellent test-retest reliability values (k>0.77; PABAK>0.90), both globally and individually for the muscles evaluated, and PA>90%, therefore above the thresholds for clinical applicability. However, the global assessment of myofascial pain and the evaluation of the medial pterygoid muscle showed slightly lower reliability values. Conclusion The IC test is reliable for the assessment of subjects with muscular TMD, both in terms of the global assessment and the evaluation of each muscle, which supports its clinical applicability. Care should be taken when assessing myofascial pain globally and when evaluating the medial pterygoid in all types of pain.

ABSTRACT Background Cultural and social factors play an important role in the development and persistence of Low Back Pain (LBP). Nevertheless, there are few studies investigating differences in LBP features between countries. Objective To determine differences in pain perception between individuals with LBP living in Brazil and Spain. Method Thirty Spanish individuals and 30 age- and sex-comparable Brazilian individuals with LBP were recruited from the Public Health Services of both countries. The Numerical Pain Rating Scale and the pain rating index (PRI), the number of words chosen (NWC), and the present pain index (PPI) extracted from the McGill Pain Questionnaire were used to assess pain. The Oswestry Disability Index, the Short Form-36, Beck Depression Inventory-II, and Pittsburgh Sleep Quality Index were also applied. Differences between countries and the correlation between demographic and clinical variables in each country were assessed with parametric and the nonparametric tests. Results A significant Country by Gender interaction was found for the PRI total score (P=0.038), but not for intensity of pain, disability, PPI, or NWC, in which Spanish women exhibited greater pain ratio than Spanish men (P=0.014), and no gender differences were identified in Brazilians. The Spanish group showed a consistent pattern of correlations for clinical data. Within Brazilian patients, fewer correlations were found and all of the coefficients were lower than those in the Spanish group. Conclusion The pain perception in patients with LBP is different depending on the country. Within Spanish patients, LBP is considered a more global entity affecting multidimensional contexts.

Objetivo: Identificar as relações entre intensidade da dor, qualidade de vida relacionada à saúde, incapacidade, qualidade do sono e dados demográficos em idosos com artroplastia total de joelho (ATJ). Métodos: Participaram vinte e quatro pacientes que receberam ATJ no mês anterior (4 mulheres; 66 ± 9 anos) e 21 controles comparáveis (8 homens; 70 ± 9 anos). Foram coletadas a intensidade da dor no momento da avaliação, a maior e a menor intensidade de dor sentida na semana anterior. A função (Western Ontario and McMaster Universities index), a qualidade de vida (Medical Outcomes Study Short Form 36), e a qualidade do sono (Pittsburgh Sleep Quality Index) foram avaliadas. Idade, sexo, peso, altura, índice de massa corporal também foram coletados. Resultados: Indivíduos com ATJ mostraram pior função física (P < 0,01), papel social (P = 0,01), desempenho físico (P < 0,01), dor (P = 0,04), incapacidade (P = 0,04) e qualidade do sono (P = 0,03) do que os controles. Maior intensidade da dor foi associada com menor função física, papel social, saúde mental, vitalidade e saúde geral, e com maior incapacidade e qualidade do sono. Incapacidade e qualidade do sono estiveram associa das negativamente com vários domínios de qualidade de vida. As associações entre a intensidade da dor, incapacidade, qualidade de vida e do sono mostram a experiência multidimensional da ATJ.

The scope of this paper was to study the relationship between pain intensity, health-related quality of life, disability, sleep quality and demographic data in elderly people with total knee arthroplasty (TKA). 24 subjects who had been subjected to TKA the previous month (4 females; 66 ± 9years) and 21 comparable controls (8 male; 70 ± 9years) participated in the study. Intensity of pain, and highest and lowest pain intensity experienced in the preceding week were collected. The Western Ontario and McMaster Universities index function, quality of life (Medical Outcomes Study Short Form 36), and Pittsburgh Sleep Quality Index were assessed. Age, gender, weight, height, body mass index were also collected. Individuals with TKA presented worse physical function (P < 0.01), social role (P = 0.01), physical performance (P < 0.01), pain (P = 0.04), disability (P = 0.04) and sleep quality (P = 0.03) than the controls. Higher intensity of pain was associated with lower physical function, social role, mental health, vitality and general health, and with higher disability and sleep quality. Disability and sleep quality were negatively associated with several quality of life domains. The associations between the intensity of pain, disability, quality of life and sleep reveal the multidimensional experience of TKA.

Objective: To compare the prevalence of chronic headache (CH), chronic neck pain (CNP) and chronic low back pain (CLBP) in the autonomous region of Madrid by analyzing gender differences and to determine the factors associated with each pain location in women in 2007. Methods: We analyzed data obtained from adults aged 16 years or older (n = 12,190) who participated in the 2007 Madrid Regional Health Survey. This survey includes data from personal interviews conducted in a representative population residing in family dwellings in Madrid. The presence CH, CNP, and CLBP was analyzed. Sociodemographic features, self-perceived health status, lifestyle habits, psychological distress, drug consumption, use of healthcare services, the search for alternative solutions, and comorbid diseases were analyzed by using logistic regression models. Results: The prevalence of CH, CNP and CLBP was significantly higher (P<0.001) in women (7.3%, 8.4%, 14.1%, respectively) than in men (2.2%, 3.2%, 7.8%, respectively). In women, CH, CNP and CBLP were significantly associated with having >3 chronic diseases (OR 7.1, 8.5, 5.8, respectively), and with the use of analgesics and drugs for inflammation (OR: 3.5, 1.95, 2.5, respectively). In the bivariate analysis, the factors associated with pain in distinct body locations differed between men and women. Conclusions: This study found that CH, CNP and CLBP are a major public health problem in women in central Spain. Women have a higher overall prevalence of chronic pain than men. Chronic pain was associated with a higher use of analgesics and healthcare services.

Objective: To analyze time trends in the prevalence of leisure time (LTPA) and work-related (WRPA) physical activity between 1987 and 2006 in the Spanish working population. Methods: We analyzed data taken from the Spanish National Health Surveys for 1987 (n = 29,647), 1993 (n = 20,707), 1995-1997 (n = 12,800), 2001 (n = 21,058), 2003 (n = 21,650), and 2006 (n = 29,478). The main variables were LTPA and WRPA in working adults aged 18-64 years old. We analyzed sociodemographic characteristics, self-perceived health status, lifestyle habits and associated comorbidities using multivariate logistic regression models. Results: The prevalences of LTPA and WRPA were lower in women than in men (p < 0.05). The practice of LTPA (OR: 1.54, 95%CI: 1.32-1.80 for women; OR = 1.15, 95%CI: 1.02-1.31 for men) and WRPA (OR = 1.73, 95%CI: 1.38-2.19 for women; OR = 1.55, 95%CI: 1.44-1.91 for men) significantly increased from 1987 to 2006. In both genders, the variables associated with a higher likelihood of practicing LTPA were greater age, higher educational level and being an ex- or non-smoker, while negative predictors included being married, worse self-perceived health, and obesity. Factors that increased the probability of reporting WRPA were being married, worse self-rated health status, and sleeping > 8h per day. The only factor that reduced the probability of reporting WRPA was being an ex- or non-smoker. Conclusions: We found an increase in LTPA and WRPA in the last 20 years in the Spanish working population. Several factors were associated with a higher or lower likelihood of practicing LTPA or WRPA in this population.

Objetivo: Analizar la tendencia en la práctica de actividad física en el tiempo libre (AFTL) y de actividad física en el tiempo de trabajo (AFTT) entre 1987 y 2006 en la población trabajadora española. Métodos: Se analizaron datos procedentes de la Encuesta Nacional de Salud realizada por el Instituto Nacional de Estadística en 1987 (n = 29.647), 1993 (n = 20.707), 1995-1997 (n = 12.800), 2001 (n = 21.058), 2003 (n = 21.650) y 2006 (n = 29.478). Se analizaron la AFTL y la AFTT en la población trabajadora de 18 a 64 años de edad como variables principales. Se investigaron características sociodemográficas, percepción del estado de salud, hábitos de vida y enfermedades asociadas mediante análisis multivariados. Resultados: Las mujeres mostraron una menor prevalencia de AFTL y AFTT en comparación con los hombres (p <0,05). La práctica de AFTL (odds ratio [OR] = 1,54, intervalo de confianza del 95% [IC95%]: 1,32-1,80 para las mujeres; OR = 1,15, IC95%: 1,02-1,31 para los hombres) y de AFTT (OR = 1,73; IC95%: 1,38-2,19 mujeres; OR = 1,55, IC95%: 1,44-1,91 hombres) aumentó significativamente entre 1987 y 2006. Edad más adulta, nivel educacional más alto y ser ex fumador se asociaron con una mayor práctica de AFTL tanto en hombres como en mujeres, mientras que estar casado, percepción negativa de salud y obesidad se asociaron con una menor práctica de AFTL. Estar casado, percepción negativa de salud y dormir > 8h al día se asociaron a mayor práctica de AFTT, mientras que ser ex fumador se asoció a menor práctica de AFTT. Conclusiones: La práctica de AFTL y AFTT ha aumentado significativamente en los últimos 20 años en la población trabajadora española. Diferentes factores se asocian a una mayor o menor práctica de AFTL y AFTT en esta población.

This study aimed to investigate the immediate effects of the secretory immunoglobulin A (sIgA), α-amylase activity and blood pressure levels after the application of a Reiki session in nurses with Burnout Syndrome. A randomized, double-blind, placebo-controlled, crossover design was conducted to compare the immediate effects of Reiki versus control intervention (Hand-off sham intervention) in nurses with Burnout Syndrome. Sample was composed of eighteen nurses (aged 34-56 years) with burnout syndrome. Participants were randomly assigned to receive either a Reiki treatment or a placebo (sham Reiki) treatment, according to the established order in two different days. The ANOVA showed a significant interaction time x intervention for diastolic blood pressure (F=4.92, P=0.04) and sIgA concentration (F=4.71, P=0.04). A Reiki session can produce an immediate and statistically significant improvement in sIgA concentration and diastolic blood pressure in nurses with Burnout Syndrome.
