The best internal structure of the Diabetes Quality of Life Measure (DQOL) in Brazilian patients.

BACKGROUND: Diabetes Mellitus (DM) is considered a chronic disease with numerous secondary complications that negatively affect the quality of life of patients. However, the specific, known and validated instruments for Brazilian Portuguese are too extensive, which often makes their use infeasible. OBJECTIVE: To validate the internal structure of the Brazilian version of the Diabetes Quality of Life (DQOL) measure. METHODOLOGY: Patients with DM type 1 or 2, between the ages of 18 and 76, were evaluated between April 2022 and May 2022. The survey was conducted online using the Google Forms platform. The original DQOL contains 46 multiple-choice questions organized into four domains. For structural validity, confirmatory factor analysis (CFA) was performed using RStudio software (Boston, MA, USA) with the packages lavaan and semPlot. RESULTS: A total of 354 subjects were evaluated. The 3-domain, 24-item version of the DQOL was the most adequate, with acceptable values for all fit indices (chi-square/GL < 3, TLI and CFI > 0.90, and RMSEA and SRMR < 0.08). CONCLUSION: The structure with three domains and 24 items is the most appropriate based on factor analysis. The Brazilian version of the DQOL with a structure of 3 domains and 24 items has adequate measurement properties that support its use in the clinical and scientific context in patients with DM.

Regular Physical Exercise Adherence Scale (REPEAS): a new instrument to measure environmental and personal barriers to adherence to regular physical exercise.

OBJECTIVE: To create, develop, and validate a scale that identifies the environmental and personal barriers that make it difficult to adhere to the practice of physical exercise on a regular basis in a population of Brazilian adults. METHODS: We include adult individuals, aged 18-59 years, practitioners or former practitioners of physical exercise, with Brazilian Portuguese as their mother tongue. In the development and validation phases of the process, 6 specialists in the field of the health assessed the content validity: firstly, the specialists were asked to freely list the questions they would ask to investigate the barriers to adherence to regulating physical activity. Secondly, after compiling all the suggestions listed and eliminating suggestions with similar content, the items suggested in the first round were sent to the specialists so that an evaluation of all questions using a 5-point Likert scale and the content validity coefficient was calculated. We then evaluated the structural validity, construct validity, reliability, internal consistency, and ceiling and floor effects of the Regular Physical Exercise Adherence Scale (REPEAS). RESULTS: Sixteen items were proposed to measure the factors that make it difficult to adhere to the regular practice of physical exercise. The internal structure of the REPEAS initially tested was based on the theoretical proposal of creating the instrument with two domains. After the structural analysis, we used the modification indices to identify the redundant items of the instrument. Consequently, the final version of the REPEAS after factor analysis had 12 items. Thus, the structure with 2 domains and 12 items presented adequate fit indices. With regard to construct validity, the REPEAS scores were compared in two distinct groups: irregular practitioners/ex-practitioners versus regular practitioners of physical exercise, in which a significant difference could be observed between groups (p < 0.001) for both the domains. Acceptable reliability was observed for the environment and personal domains, with ICC values of 0.86 and 0.94, in the same order. For internal consistency, Cronbach's alpha value was 0.908 (environmental domain) and 0.915 (personal domain), these values being adequate for the REPEAS. CONCLUSION: The REPEAS is a scale with a valid two-dimensional internal structure, consisting of 12 items, reliable and with a valid construct, which supports its use in the clinical, epidemiological, and research contexts in Brazil.

Short-term heart rate variability at rest in individuals with temporomandibular disorder: a comparative analysis.

OBJECTIVE: Compare heart rate variability (HRV) indices in participants with and without myogenic temporomandibular disorder (TMD). Secondarily, we correlated HRV indices with pain and quality of life variables. METHODS: This is a comparative observational cross-sectional study. Individuals of both genders with and without a history of TMD were included. Short-term heart rate variability was assessed using a Polar V800. Central sensitization was assessed using the Central Sensitization Inventory. Pain through the numeric pain scale and the impact of oral health on quality of life using the OHIP-14 questionnaire. RESULTS: A total of 80 participants were enrolled in the study: most individuals included in both groups were young adults, women and slightly overweight. We observed a decrease in HRV in the TMD group (p < 0.01) when compared to the control group. In addition, we observed a greater impact of oral health on quality of life, central sensitization in addition to high resting pain scores (p < 0.01). We observed significant correlation between the LF index of HRV and the FAI score (r = 0.311; p = 0.05). The NPS, CSI and OHIP-14 scores did not correlate with any of the HRV indices (p > 0.05). CONCLUSION: The short-term HRV in individuals with TMD is significantly lower when compared to a control group. Furthermore, there seems to be a relationship between the severity of the dysfunction and the HRV variables. CLINICAL RELEVANCE: Using portable and low-cost devices, the HRV can be easily collected and analyzed, without the need for an arsenal of equipment such as the conventional electrocardiogram. This measure can contribute to the therapy adopted and identify individuals prone to unfavorable outcomes involving ANS modulation.

Translation, cross-cultural adaptation and validation of the Work Role Functioning Questionnaire 2.0 into Brazilian Portuguese in a general population.

BACKGROUND: The Work Role Functioning Questionnaire 2.0 (WRFQ 2.0) is an instrument that measures the difficulties perceived by workers in meeting work demands, given their physical or emotional health, but it has not yet been adapted for Brazil. Thus, this study aimed to translate, cross-culturally adapt and assess the psychometric properties of the WRFQ 2.0 into Brazilian Portuguese. METHODS: This is an observational study. Initially, translation and cross-cultural adaptation into Brazilian Portuguese was carried out. After that, this version was submitted to an evaluation of its internal structure. The internal consistency and test-retest reliability were assessed. To determine the construct validity, Spearman's correlation coefficient (rho) was used to determine the magnitude of correlation between the WRFQ 2.0 and the Work Ability Index (WAI), Numerical Pain Rating Scale (NPRS) and Self -Estimated Functional Inability because of Pain (SEFIP-work). RESULTS: The internal structure with five domains and 27 items presented adequate fit indices for the Brazilian version of the WRFQ 2.0. Adequate correlations of the five domains of the WRFQ 2.0 with the NPRS, WAI and SEFIP-work were found (rho ranged between 0.145 and 0.338). The test-retest reliability of the WRFQ 2.0 ranged from substantial to excellent (intraclass correlation coefficient ≥ 0.785) and internal consistency was adequate (Cronbach's alpha ≥ 0.852). CONCLUSION: The Brazilian Portuguese version of the WRFQ 2.0 presents valid internal structure with five domains and 27 items, adequate construct based on correlations with other instruments, and acceptable test-retest reliability and internal consistency.

Brazilian version of the Neck Bournemouth Questionnaire does not have a well-defined internal structure in patients with chronic neck pain.

OBJECTIVE: To investigate the structural validity of the Brazilian version of the Neck Bournemouth Questionnaire in patients with chronic neck pain. DESIGN: Cross-sectional study. SETTING: Community participants collected via online platform. SUBJECTS: Participants with neck pain (minimal pain intensity of 3 points at rest on 11-point Numerical Rating Scale), both genders and aged ⩾18 years old. MAIN MEASURE: The Numerical Rating Scale, Neck Disability Index, Pain-Related Catastrophizing Thoughts Scale, Tampa Scale of Kinesiophobia and the Neck Bournemouth Questionnaire were completed. Exploratory and confirmatory factor analyses were used to identify dimensionality and to compare different structures of the Neck Bournemouth Questionnaire. RESULTS: We included 103 participants. The sample consisted mostly of adults (mean age = 33.64 years, standard deviation = 10.48 years), females (n = 82, 79.6%), lean, single and with higher education. The exploratory factor analysis with implementation of the parallel analysis identified the one-dimensional structure of the Neck Bournemouth Questionnaire, with a Kaiser-Meyer-Olkin value of 0.80 and Bartlett's test significant (P < 0.05). We observed that all structures tested in this study presented a high amount of residues in confirmatory factor analysis, which were identified by the value of root mean square error of approximation > 0.08 and chi-square/degree of freedom > 3.00. CONCLUSION: The internal structure of the Brazilian version of the Neck Bournemouth Questionnaire is not clear and well-defined. It was not possible to identify the construct measured by the instrument in individuals with chronic neck pain.

Additional Effects of a Physical Therapy Protocol on Headache Frequency, Pressure Pain Threshold, and Improvement Perception in Patients With Migraine and Associated Neck Pain: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the additional effect provided by physical therapy in migraine treatment. DESIGN: Randomized controlled trial. SETTING: Tertiary university-based hospital. PARTICIPANTS: Among the 300 patients approached, 50 women (age range, 18-55y) diagnosed with migraine were randomized into 2 groups: a control group (n=25) and a physiotherapy plus medication group (n=25) (N=50). INTERVENTIONS: Both groups received medication for migraine treatment. Additionally, physiotherapy plus medication patients received 8 sessions of physical therapy over 4 weeks, comprised mainly of manual therapy and stretching maneuvers lasting 50 minutes. MAIN OUTCOME MEASURES: A blinded examiner assessed the clinical outcomes of headache frequency, intensity, and self-perception of global change and physical outcomes of pressure pain threshold and cervical range of motion. Data were recorded at baseline, posttreatment, and 1-month follow-up. RESULTS: Twenty-three patients experienced side effects from the medication. Both groups reported a significantly reduced frequency of headaches; however, no differences were observed between groups (physiotherapy plus medication patients showed an additional 18% improvement at posttreatment and 12% improvement at follow-up compared with control patients, P>.05). The reduction observed in the physiotherapy plus medication patients was clinically relevant at posttreatment, whereas clinical relevance for control patients was demonstrated only at follow-up. For pain intensity, physiotherapy plus medication patients showed statistical evidence and clinical relevance with reduction posttreatment (P<.05). In addition, they showed better self-perception of global change than control patients (P<.05). The cervical muscle pressure pain threshold increased significantly in the physiotherapy plus medication patients and decreased in the control patients, but statistical differences between groups were observed only in the temporal area (P<.05). No differences were observed between groups regarding cervical range of motion. CONCLUSIONS: We cannot assume that physical therapy promotes additional improvement in migraine treatment; however, it can increase the cervical pressure pain threshold, anticipate clinically relevant changes, and enhance patient satisfaction.

Generalized Pressure Pain Hypersensitivity in the Cervical Muscles in Women with Migraine.

OBJECTIVE: To investigate the differences in pressure sensitivity in the cervical musculature including the upper trapezius, sternocleidomastoid, suboccipital, levator scapulae, and anterior scalene muscles between women with migraine and healthy controls. DESIGN: Cross-sectional study. SUBJECTS: Thirty women with migraine and 30 healthy women participated. METHODS: Pressure pain thresholds (PPT) were bilaterally assessed over upper trapezius, sternocleidomastoid, suboccipital, levator scapulae, and anterior scalene muscles in a blinded design. Mean values of both sides were pooled for statistical analysis. Comparison between groups was performed by unpaired Student t-test and correlation with headache features with Spearman's correlation test. RESULTS: Migraine patients exhibited lower PPT in all muscles compared with controls: upper trapezius (P = 0.046); suboccipital (P < 0.001); sternocleidomastoid (P < 0.001); anterior scalene (P < 0.001), and levator scapulae (P < 0001). No associations were observed between the frequency and the intensity of migraine or years with the disease and PPT. CONCLUSION: This study showed generalized pressure pain hypersensitivity in the cervical musculature in women with migraine. Our findings provide support for the physical therapy treatment and evaluation of musculoskeletal cervical spine disorders in individuals with migraine and reinforce that all cervical muscles should be evaluated.

Measurement properties of the Brazilian version of the Kidney Symptom Questionnaire.

OBJECTIVE: The aim of this study was to measure the reliability, internal consistency, and construct validity of the Kidney Symptom Questionnaire for the Brazilian population. METHODS: This is a cross-cultural adaptation and questionnaire validation study. We included native Brazilians of both sex aged>18 years, as well as hypertensive and/or diabetic patients. All participants were assessed using Screening for Occult Renal Disease, EuroQol 5 Dimensions, 36-Item Short Form Survey, and the Kidney Symptom Questionnaire. We used Spearman's coefficient (rho) to measure the correlations between the Kidney Symptom Questionnaire and other instruments; Cronbach's alpha to measure internal consistency; and intraclass correlation coefficient, standard error of measurement, and minimum detectable change to measure test-retest reliability. RESULTS: The sample was formed by 121 adult participants, mostly female, with systemic arterial hypertension and/or diabetes mellitus. We found excellent reliability (intraclass correlation coefficient≥0.978), adequate internal consistency (Cronbach's alpha≥0.860), and adequate construct validity on the Kidney Symptom Questionnaire domains; besides, we observed significant correlations between the Kidney Symptom Questionnaire and other instruments. CONCLUSION: The Brazilian version of the Kidney Symptom Questionnaire has adequate measurement properties to assess chronic/occult kidney disease in patients who do not require renal replacement therapy.

Fear of Return to Sport Scale (FRESS): a new instrument for use in injured professional or recreational athletes in rehabilitation.

Objective: To create, develop, and validate the Fear of Return to Sport Scale (FRESS) for injured professional or recreational athletes in rehabilitation. Methods: This is a questionnaire validation study. To determine the structural and construct validity, 192 injured professional or recreational athletes of different sports modalities were included. We used a subsample with 32 participants to analyze test-retest reliability and internal consistency. Main outcome measures were the FRESS, Numerical Pain Scale (NPS), Pain-Related Catastrophizing Thoughts Scale (PCTS), Self-Estimated Functional Inability because of Pain Questionnaire for athletes (SEFIP-sport), and Hospital Anxiety and Depression Scale (HADS). Results: Initially, 25 questions were proposed by the specialists. Of these, 4 questions were excluded due to similarity with others. After applying the content validity coefficient, 8 questions were excluded for presenting a value lower than 0.80, leaving 13 items. The exploratory factor analysis identified the one-dimensional structure of the FRESS with 13 items. However, five items were excluded for presenting high covariance with the error of several other FRESS items in the confirmatory factor analysis. Thus, the final version of the FRESS was defined with one domain and eight items. Regarding the construct validity, we observed a magnitude of correlation varying between 0.257 and 0.470 between the FRESS and the instruments used here. We observed adequate test-retest reliability (intraclass correlation coefficient = 0.896) and internal consistency (Cronbach's alpha = 0.868). Ceiling and floor effects were not observed. Conclusion: The FRESS with one domain and eight items has acceptable measurement properties and its use in clinical and sports environments to measure the fear of returning to sport in injured professional or recreational athletes is supported. Supplementary Information: The online version contains supplementary material available at 10.1007/s11332-022-00975-4.

Correlation between baropodometric variables, disability, and intensity of low back pain in pregnant women in the third trimester.

BACKGROUND: Growth of uterus, enlargement of breasts and weight gain result from the development and growth of the fetus during pregnancy. The posture and the displacement of the center of gravity change. OBJECTIVE: Correlate baropodometric variables with low back pain in pregnant women in the third trimester of pregnancy. METHODS: This is a cross-sectional analytical study conducted in São Luís (MA, Brazil). For data collection, we used a form containing sociodemographic and clinical data, Oswestry Disability Questionnaire for disability evaluation of the lumbar spine, Numerical Rating Scale to measure pain intensity, and baropodometric evaluation. RESULTS: Twenty-five pregnant women took part in the study. There was a significant and positive correlation (r = 0.404, p = 0.045) between functional disability and hindfoot pressure and a significant and negative correlation (r = -0.404, p = 0.045) between functional disability and plantar pressure in the forefoot of the right foot. In addition, there was a positive and significant correlation between the intensity of pain and the contact area on the left (r = 0.504, p = 0.010) and right (r = 0.509, p = 0.009) foot. CONCLUSION: There is a relation between disability and plantar pressure and between pain intensity and area of contact of feet in pregnant women.

Relationship between obstructive sleep apnea syndrome and functional capacity in patients with diabetes mellitus type 2: an observational transversal study.

OBJECTIVE: The aim of this study was to verify the association among obstructive sleep apnea, functional capacity, and metabolic control. METHODS: This was a cross-sectional study involving individuals of both sexes with clinical diagnosis of diabetes mellitus type 2 who were above 18 years of age. The assessment consisted of a volunteer identification form, a 2-minute step test, and the Stop-Bang questionnaire. In order to assess metabolic control, HbA1c and fasting glucose data were collected from medical records. RESULTS: A total of 100 individuals with diabetes mellitus type 2, of whom 61% were women, were included in this study. According to the Stop-Bang instrument, 26, 57, and 17% of patients had low, intermediate, and high risk of developing OSA, respectively. There was no association between the 2-minute step test and metabolic variables and diabetes mellitus type 2 chronicity with Stop-Bang. CONCLUSIONS: We concluded that there is no association among obstructive sleep apnea measured by means of Stop-Bang instrument, functional capacity measured by means of 2-minute step test, and metabolic variables in individuals with diabetes mellitus type 2.

Sickle Cell Anaemia Prevalence Among Newborns in the Brazilian Amazon-Savanna Transition Region.

Sickle cell anaemia is one of the most common hemoglobinopathies worldwide and an important public health problem in Brazil. This study evaluated the prevalence of sickle cell anaemia and its traits in newborns from the Amazon-Savanna Transition Region in the state of Maranhão, Brazil. A cross-sectional study was carried out, based on data from neonatal screening tests performed in 2013-2015 in Maranhão. The Hardy-Weinberg theorem was applied to analyse the frequency of expected homozygotes based on HbSS phenotype. A spatial-temporal distribution analysis was performed to delimit the regions with the greatest number of newborn cases with sickle cell anaemia. Of 283,003 newborns, 162 were found to have sickle cell anaemia, while 10,794 had a sickle cell trait, with a prevalence of 0.05% and 3.8%, respectively. The prevalence of expected homozygotes was higher in the North Region and in the state capital of Maranhão. This study may contribute to existing social and public health actions or the creation of new strategies for sickle cell disease in endemic areas in Brazil to improve the quality of life.

Correlation Between Habitual Physical Activity and Central Sensitization, Pain Intensity, Kinesiophobia, Catastrophizing, and the Severity of Myogenous Temporomandibular Disorder.

OBJECTIVE: We sought to correlate habitual physical activity with central sensitization, pain intensity, kinesiophobia, catastrophizing, and the severity of chronic myogenous temporomandibular disorder (TMD). METHODS: This was an observational study. Fifty-five individuals, male and female, aged 18 to 45 years, with pain for at least 3 months (chronic) related to myogenous TMD were included in the study. Myogenous TMD was evaluated by means of the Numerical Rating Scale, Catastrophic Thoughts on Pain Scale, Tampa Scale for Kinesiophobia, Fonseca Anamnestic Index, Central Sensitization Inventory, and habitual physical activity by means of the Baecke Questionnaire (BQ). The Spearman correlation coefficient (r s) was applied to verify the association of the BQ score with the pain variables. RESULTS: No significant correlations (P > .05) were observed in the total or mean BQ scores (both r s = -0.17 to -0.04), nor in the analyses performed on the occupational (r s = -0.03 to 0.14), sport (r s = -0.16 to 0.01), and leisure domains (r s = -0.16 to -0.02). CONCLUSION: Habitual physical activity as measured by the BQ is not associated with pain intensity, catastrophizing, kinesiophobia, central sensitization, or the severity of chronic myogenous TMD.

Translation, Cross-Cultural Adaptation, and Validation of the Hypertension Self-Care Profile (HBP-SCP) for the Brazilian Population

Abstract Background Self-care in the management of systemic arterial hypertension (SAH) is crucial, and validated instruments can help researchers and health professionals to plan strategies to improve self-care in people with SAH. Objective The main objective of this study was to translate, cross-culturally adapt, and validated the Hypertension Self-Care Profile (HBP-SCP) for Brazilian Portuguese. Methods The translation and cross-cultural adaptation was performed in five phases, and the pre-final version was tested in 30 individuals, native speakers of Portuguese with a diagnosis of hypertension. The final version was administered in 100 individuals. The inclusion criteria were: diagnosis of SAH, characterized by systolic arterial blood pressure ≥ 140 mmHg and/or diastolic arterial blood pressure ≥ 90mmHg, regular use of antihypertensive medications and over 18 years of age. The present study also used two other questionnaires, previously validated for the Brazilian population, to verify the validity of the construct, the Healthy Habits Perception Questionnaire (HHPQ) and the Quality of Life in Hypertension Mini-Questionnaire (MINICHAL-BRASIL). Results During the translation and cross-cultural adaptation phase, there were no disagreements. Adequate reliability — intraclass correlation coefficient (ICC) ≥ 0.89, standard error of measurement (SEM) % ≤ 4.34, minimum detectable change (MDC) % ≤ 12.04 — and internal consistency (Cronbach's alpha ≥ 0.75) were observed. The behavior domain of HBP-SCP obtained significant correlations (p < 0.05) with the self-efficacy domain and HHPQ; the motivation domain with the self-efficacy domain; and the self-efficacy domain with the somatic manifestation domain of MINICHAL-BRASIL. No ceiling and floor effects were observed. Conclusions The Brazilian Portuguese version of the HBP-SCP has adequate psychometric properties, according to the best scientific recommendations.

Resultados: Participaram 104 idosos, classificados com ausência de risco para quedas (67.3%), não vulneráveis (67.3%) e como obesos (24%). Não foi observada correlação entre obesos com o risco de quedas no tempo em segundos do TUG [ρ= -0.115; p>0.05] e com a classificação do TUG [ρ= -0.152; p>0.05]. Porém, foi observada correlação entre a vulnerabilidade com o risco de quedas no tempo em segundos do TUG [ρ= 0.217; p<0.05]. Conclusão: Não foi observada correlação entre obesidade e risco para quedas. Contudo, verificou-se que quando mais vulnerável maior é o risco para quedas.

Objective:To investigate the correlation of the risk of falling with the decrease in functional mobility, vulnerability and obesity in the elderly.Method:Cross-sectional study. Active elderly people of both sexes, aged between 60-85 years were evaluated, and volunteers who did not undergo the evaluative tests proposed to identify functional mobility and nutritional status were excluded.The Body Mass Index (BMI) tests were applied, which classified the nutritional status of malnutritionBMI ≤ 22, nutritional risk BMI= 22.1-24.0,ideal weight BMI= 24.1-27.0, overweight BMI 27.1-30 and obesity with BMI > 30.0,the Timed Up & Go (TUG) to identify functional mobility and functional risks related to falls in the elderly and the classification adopted for this study was ≥ 10s being risk indicators for falls and the Vulnerable Elders Survey (VES-13) that classified as vulnerable elderly, volunteers with a score > 2 points.Statisticalanalysiswasperformedat 95% confidencelevel and p<0.05. Results:104 elderlypeopleparticipated, classified as having no risk for falls (67.3%), non-vulnerable (67.3%) and as obese (24%). There was no correlation between obese subjects andthe risk of falls in TUG time in seconds [ρ= -0.115; p>0.05] andwith the TUG classification [ρ= -0.152; p>0.05]. However, there was a correlation between vulnerability and the risk of falls in time in seconds of the TUG [ρ= 0.217; p<0.05].Conclusion:Nocorrelation was observed between obesity and risk of falls. However, it was found that the more vulnerable the greater the risk for falls.

Association between the total of falls reported and the number of home ergonomic barriers / Associação entre o total de quedas relatadas e o número de barreiras ergonômicas domiciliares

Objective: To investigate the association between the total number of falls in the last year and the number of home ergonomic barriers (HEB). Method: Cross-sectional study, Volunteers aged ≥60 years were included in the study. The history of falls and the number of HEBs were evaluated via a questionnaire. vulnerability through the Vulnerable Elders Survey 13 (VES-13) and fear of falling observed by the Falls Efficacy Scale - International- Brazilian (FES-I-BR). Data normality was verified with the Kolmogorov-Smirnov test, the correlation between total falls and the number of ergonomic barriers was verified with the Spearman test and the association between ergonomic barriers and groups with and without a history of falls, in the last year, through bivariate logistic regression and the chi-square test, the significance level of p≤ 0.05 was adopted. Results: Of the 123 individuals evaluated, 48% had a history of falls, with a mean of 3.83±1.96. The lack of support bars was considered protective [OR= 0.30; p= 0.042] and the absence of uniform floors and well-fixed mats were considered as risk factors for falls [OR= 3.71; p= 0.004]. Elderly people with a history of falls with ≥ 04 HEB, presented a greater risk of falls [OR= 5.98 p<0.0001]. Conclusion: The amount ≥ 04 HEB is associated with a history of falls, the absence of handrails is a protective factor, and uneven or slippery floors are risk factors for falls.

Objetivo: Investigar a associação entre o número total de quedas no último ano e o número de barreiras ergonômicas domiciliares (BED). Método: Estudo transversal, voluntários com idade ≥60 anos foram incluídos no estudo. A história de quedas e o número de BED foram avaliados por meio de um questionário, a vulnerabilidade através do Vulnerable Elders Survey 13 (VES-13) e o medo de cair observado pela Falls Efficacy Scale - International- Brazilian (FES-I-BR). A normalidade dos dados foi verificada com o teste de Kolmogorov-Smirnov, a correlação entre total de quedas e a quantidade de barreiras ergonômicas foi verificada com teste de Spearman e associação entre as barreiras ergonômicas e os grupos com e sem histórico de quedas no último ano, através da regressão logística bivariada e pelo teste de Qui-quadrado, o nível de significância de p≤ 0,05 foi adotado. Resultados: Dos 123 indivíduos avaliados, 48% tinham histórico de quedas, com média de 3,83±1,96. A falta de barras de apoio foi considerada protetora [OR= 0,30; p= 0,042] e a ausência de pisos uniformes e tapetes bem fixados foram considerados fatores de risco para quedas [OR= 3,71; p= 0,004]. Idosos com histórico de quedas com ≥ 04 BED, apresentaram maior risco de quedas [OR= 5,98 p<0,0001]. Conclusão: A quantidade ≥ 04 BED está associada a histórico de quedas, a ausência de corrimão é fator de proteção e pisos irregulares ou escorregadios são fatores de risco para quedas.

Relationship between obstructive sleep apnea syndrome and functional capacity in patients with diabetes mellitus type 2: an observational transversal study

SUMMARY OBJECTIVE: The aim of this study was to verify the association among obstructive sleep apnea, functional capacity, and metabolic control. METHODS: This was a cross-sectional study involving individuals of both sexes with clinical diagnosis of diabetes mellitus type 2 who were above 18 years of age. The assessment consisted of a volunteer identification form, a 2-minute step test, and the Stop-Bang questionnaire. In order to assess metabolic control, HbA1c and fasting glucose data were collected from medical records. RESULTS: A total of 100 individuals with diabetes mellitus type 2, of whom 61% were women, were included in this study. According to the Stop-Bang instrument, 26, 57, and 17% of patients had low, intermediate, and high risk of developing OSA, respectively. There was no association between the 2-minute step test and metabolic variables and diabetes mellitus type 2 chronicity with Stop-Bang. CONCLUSIONS: We concluded that there is no association among obstructive sleep apnea measured by means of Stop-Bang instrument, functional capacity measured by means of 2-minute step test, and metabolic variables in individuals with diabetes mellitus type 2.

Is pressure pain sensitivity over the cervical musculature associated with neck disability in individuals with migraine?

The objective was to determine if disability due to neck pain is correlated with pressure pain sensitivity in the cervical muscles in patients with migraine. Thirty-two volunteers with migraine completed the Neck Disability Index (NDI). Pressure pain thresholds (PPT) over the sternocleidomastoid, upper trapezius and suboccipital muscles were also assessed. Data were analyzed using the Spearman correlation coefficient (rs) and linear regression models (α < 0.05). Moderate negative correlations between NDI and PPT were obtained for the sternocleidomastoid (rs = -0.42; p = 0.001), upper trapezius (rs = -0.33; p = 0.001) and suboccipital muscles (rs = -0.41; p = 0.001). The linear regression revealed no association between NDI and PPT of sternocleidomastoid (ß = 0.01; R(2) = 0.17), upper trapezius (ß = 0.01; R(2) = 0.11) and suboccipital muscles (ß = 0.02; R(2) = 0.17). NDI scores and PPT of the cervical muscles correlated moderately and was inversely proportional in patients with migraine, but the association was not linear, so both outcomes should be considered in the assessment of this population.
