Translation, cross-cultural adaptation to Brazilian Portuguese and measurement properties of the WaLIDD score.

Objective: Dysmenorrhea is the pain related to menstruation; to screen for the symptoms, a working ability, location, intensity of days of pain, and dysmenorrhea (WaLIDD) score was created. The purpose of this work was to culturally adapt and assess the measurement properties of the WaLIDD score for dysmenorrhea in Brazilian women. Methods: In this cross-sectional online study, we evaluated women with and without dysmenorrhea. Criterion validity and construct validity were assessed, respectively, by the Receiver Operator Characteristic (ROC) curve and correlations with the bodily pain and social functioning domains of medical outcomes study 36-item short-form health survey (SF-36), self-report of absenteeism and Stanford Presenteeism Scale for presenteeism. Test-retest reliability and measurement errors were assessed, respectively, by intraclass correlation coefficient (ICC) and Bland and Altman Graph. Results: 430 women completed the test, 238 (55.4%) women had dysmenorrhea, and 199 (46.3%) answered the questionnaire twice for the retest. The cutoff points ≥4, ≥5, and ≥5 could discriminate between women with and without dysmenorrhea, absenteeism, and presenteeism related to dysmenorrhea, respectively. Correlations between SF-36 - pain and social functioning domains and WaLIDD score were weak to strong and negative. For WaLIDD total Score, ICC was 0.95 and the limits of agreement were -1.54 and 1.62. Conclusion: WaLIDD score is a short, valid and reliable instrument to screen and predict dysmenorrhea and could predict absenteeism and presenteeism related to dysmenorrhea in Brazilian women.

Use of cupping therapy in musculoskeletal disorders: A cross-sectional study on the profile, training, and practice of Brazilian physical therapists.

INTRODUCTION: Cupping therapy is a widely used technique in Brazilian physical therapy for the treatment of musculoskeletal disorders. However, there is limited scientific evidence to support its effectiveness. OBJECTIVE: To investigate the profile, training, clinical practice, and scientific updates of Brazilian Physical Therapists who use cupping therapy as a therapeutic resource for musculoskeletal disorders. METHODS: A cross-sectional study was conducted through an online questionnaire, including 646 Physical Therapists who use cupping therapy in their practice. All data were analysed descriptively. RESULTS: Cupping therapy is a technique that has been widely adopted in clinical practice by Physical Therapists, particularly among young, female professionals who have recently graduated from private universities. The primary reason for interest in this technique among these Physical Therapists is the high demand from patients. Additionally, it is often used in conjunction with other manual therapeutic techniques. They identified easy access, low cost, and ease of use as the key factors that make cupping therapy an attractive option. However, a lack of high-quality scientific evidence, as described in the literature, was identified as a major barrier to its use. CONCLUSION: The Physical Therapists included in this study use cupping therapy in their clinical practice, relying heavily on their own experience and the preferences of their patients, rather than utilizing the third pillar of evidence-based practice, which is to rely on the best available evidence. This study suggests that these Physical Therapists are currently implementing a technique without current scientific recommendations for its use in the treatment of musculoskeletal disorders.

Presenteeism and associated factors among women with menstrual symptoms.

PURPOSE: Menstrual characteristics can affect a woman's productivity at work and college, but studies in a general population of adult women are scarce. In addition, it is important to know which menstrual symptoms are most associated with presenteeism in women to promote specific health actions. The present study aimed to assess menstrual symptoms associated with presenteeism in adult women. METHODS: Online cross-sectional study in which menstrual characteristics, including menstrual flow, age of menarche, menstrual pain and cycle duration were assessed by a self-report questionnaire. The menstrual pain intensity was assessed by Numerical Rating Scale, and the presenteeism, by the Stanford Presenteeism Scale-6 (SPS-6). Women were divided in two groups, with and without presenteeism, based on the SPS-6 cutoff point. Data were analyzed by binary logistic regression and presented as odds ratios (OR). RESULTS: Among the 430 women who participated in the study, 44.2% were classified as with presenteeism. Women with severe menstrual flow were more likely to have presenteeism (OR = 2.12) compared with women with mild and moderate menstrual flow. The higher menstrual pain intensity the higher the chances of a woman presenting with presenteeism (OR = 1.29). CONCLUSIONS: These menstrual characteristics (intensity of menstrual flow and menstrual pain) seem to affect women's productivity at work and/or college, and should be assessed in research and clinical practice. Thus, public policies on women's health can be carried out based on these results.

Tampa Scale for Kinesiophobia in chronic neck pain patients (TSK-neck): structural and construct validity and reliability in a Brazilian population.

BACKGROUND: To date, there are no studies in the literature that define the internal structure of the Tampa Scale for Kinesiophobia (TSK) in patients with chronic neck pain based on factorial analysis. As such, we aimed to verify and identify the best structure of the Brazilian version of the TSK in patients with chronic neck pain. METHODS: We included Brazilian participants aged ≥18 years, both sexes, with self-reported neck pain for more than 3 months and pain intensity ≥3 on the Numerical Pain Rating Scale (NPRS). Dimensionality and number of TSK items were assessed using confirmatory factor analysis (CFA). We tested the following internal structures: structure 1 (1 domain and 17 items), structure 2 (1 domain and 11 items), structure 3 (2 domains and 11 items), and structure 4 (2 domains and 9 items). We used the Pain-Related Catastrophizing Thoughts Scale (PCTS) and the NPRS for construct validity. In addition, we assessed test-retest reliability for the seven-day interval using intraclass correlation coefficient (ICC2,1), Cronbach's alpha to assess internal consistency, and ceiling and floor effects. RESULTS: The study sample included of 335 patients. Most were women (77.6%), young adults (~ 34 years), single (48.4%), with complete primary education (57.3%), physically inactive (66.6%), with a mean pain duration of 46 months and a mean pain intensity of ~ 5 points on the NPRS. Redundancy was found in the following items: item 1 with item 2 (modification indices = 21.419) and item 13 with item 15 (modification indices = 13.641). Subsequently, based on these paired analyses, the items with the lowest factor loadings (items 2 and 15) were excluded. As such, TSK structure 4 was composed of two domains ("somatic focus" and "activity avoidance") and 9 items, which showed adequate fit indices and lower AIC and SABIC values. We observed significant values (p < 0.05) with a correlation magnitude greater than 0.142 to 0.657 between the two domains of the TSK-neck and the other instruments (PCTS and NPRS). We found excellent reliability (ICC2,1 ≥ 0.96) and adequate internal consistency (Cronbach's alpha ≥0.98) of the TSK-neck. Finally, ceiling and floor effects were not observed. CONCLUSION: The TSK-neck structure with two domains (somatic focus and activity avoidance) and nine items is the most appropriate for patients with chronic neck pain.

Prevalence, pain intensity and symptoms associated with primary dysmenorrhea: a cross-sectional study.

BACKGROUND: Primary dysmenorrhea (PD) is an etiological cyclic pelvic pain related to the menstrual period; it can negatively impact women's quality of life and productivity. The aim of the present study was to estimate the prevalence of PD and analyze associated symptoms in Brazilian women. METHODS: An online cross-sectional study was carried out in Brazil, with a structured questionnaire regarding dysmenorrhea and associated symptoms. PD intensity was measured with the Numerical Rating Scale for Pain and classified as mild (1-3), moderate (4-7) and severe (> 8). The association between qualitative variables was performed using Pearson's Chi-Square Test. The quantification of this association was measured using multinomial logistic regression models, with calculation of Odds Ratio and confidence interval. A significance level of 5% was considered. RESULTS: A total of 10,070 women were included. Most participants classified PD intensity as moderate (40.4%, 41.9% and 49.7%) and severe (21.2%, 24.8% and 28.4%) in the previous month, 3 months and 5 years, respectively. The most common symptoms associated with PD were irritability, abdominal distension sensation, anxiety and feeling more emotional. The increased of the risk (OR > 1.0) for moderate and severe PD-related pain intensity is related to age, nulliparity and presence PD since adolescence. CONCLUSION: There is a high prevalence of PD among Brazilian women, and the most common symptoms reported were irritability, abdominal distension sensation, anxiety and feeling more emotional.

Pain neuroscience education improves quality of life when added to aquatic exercise therapy for women with fibromyalgia: randomized controlled clinical trial.

PURPOSE: The aim of the present study was to investigate the effects of adding Pain Neuroscience Education (PNE) to an aquatic therapy protocol on pain, fibromyalgia (FMS) impact, quality of life and sleep. MATERIALS AND METHODS: Seventy-five women were randomly allocated into two groups: aquatic exercises (AEG, n = 36) and aquatic exercises + PNE (PNG, n = 39). The primary outcome was pain, and the secondary outcomes were FMS impact, quality of life, sleep and pain sensitivity (pressure pain thresholds - PPTs). Participants performed 45-min sessions of aquatic exercises, twice a week, for 12 weeks. PNG also received 4 PNE sessions during this period. Participants were assessed four times: initial (before treatment), after 6 weeks (intermediate) and 12 weeks (final) of treatment and after 12 weeks after the end of treatment (follow-up). RESULTS: Both groups improved pain after treatment, with no difference between them (p > 0.05, partial ƞ2 0.10). FMS impact and PPTs improved after treatment with no difference between groups, and sleep did not change. Quality of life improved several domains for both groups, with slightly better results for the PNG, with low effect sizes between groups. CONCLUSIONS: The present results show that the addition of PNE to an aquatic exercise intervention did not provide larger effects than aquatic exercises alone for people with FMS concerning pain intensity, but provided benefit for health-related quality of life for this population. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03073642, version 2, April 1st, 2019). PERSPECTIVE: The addition of 4 Pain Neuroscience Education sessions to an aquatic exercises protocol did not add benefits for women with fibromyalgia syndrome on pain, fibromyalgia impact, and sleep, but improved quality of life and pain sensitivity.IMPLICATIONS FOR REHABILITATIONAquatic exercises are commonly prescribed, but patient education is crucial for the treatment.The addition of Pain Neuroscience Education to an aquatic exercises protocol did not add benefits for women with fibromyalgia syndrome.The positive changes on quality of life and pain sensitivity that this combination led to had small effect sizes and did not achieve minimal important clinical difference.

Efficacy of telerehabilitation exercise in patients with chronic neck pain: a protocol for a non-inferiority randomized controlled trial.

The aim of this study is to investigate if telerehabilitation is just as effective as the same face-to-face exercise program in patients with chronic neck pain (NP). 140 participants will participate in this non-inferiority randomized controlled trial. Primary outcomes will be pain intensity and disability, and secondary outcomes will be kinesiophobia, catastrophizing, fear avoidance beliefs, anxiety and depression symptoms, self-efficacy for pain and global perceived effect. It will be collected at baseline, 6 weeks and 6 months after intervention. The analysis of non-inferiority will be calculated by mixed linear models considering the non-inferiority margin. The results of this clinical trial will be able to overcome the barriers that physiotherapists face for the success of their therapies. In addition, it may reduce the high demands and public health costs with NP. Brazilian Clinical Trials Registry (RBR-6VBSMB). Clinical Trial Registration: REBEC (Brazilian Registry of Clinical Trials) RBR-6VBSMB (ClinicalTrials.gov).

What is this article about? This study aims to compare the effect of face-to-face and telerehabilitation treatment for chronic neck pain, since it is the third condition that causes most disability in the world among musculoskeletal conditions. In addition, because its prevalence occurs at an economically active age, it generates a drop in productivity and absenteeism at work. Due to the high public health expenses with chronic neck pain, telerehabilitation is a tool with great potential for reducing waiting lists and barriers to therapy success (transport, time, money). What do the results of the study mean? This is the first clinical trial to investigate the efficacy of telerehabilitation exercise in patients with chronic neck pain and the results will be able to overcome the barriers that physiotherapists face for the success of their therapies. In addition, it may reduce the high demands and public health costs with neck pain and may help patients experience less pain and disability and become more self-sufficient in managing their chronic condition.

Effects of progressive intensity resistance training on the impact of fibromyalgia: protocol for a blinded randomized controlled trial.

BACKGROUND: Fibromyalgia guidelines indicate that exercise is critical in the management of fibromyalgia, and there is evidence that patients with fibromyalgia can perform resistance training at moderate and high intensities. However, despite the biological plausibility that progression of intensity provides greater benefit to individuals, no studies have compared different intensities (progressive versus constant intensities) of the same exercise in this population. OBJECTIVE: To compare the effect of 24 sessions of resistance training (progressive vs. constant intensity) on impact of fibromyalgia, sleep quality, anxiety, depression, pain, walking ability, and musculoskeletal capacity. METHODS: A protocol for a blinded randomized controlled trial. The sample will be randomized into three groups: group 1 (progressive intensity, experimental), group 2 (constant intensity, control A), and group 3 (walking, control B). Group 1 will perform resistance training at moderate intensity (50% of maximum dynamic strength), previously determined by the 1 repetition maximum (1-RM) test in the proposed exercises. The strength of each individual will be reassessed every 4 weeks (by 1-RM) and the intensity of each exercise will be positively adjusted by 20% of the value observed in kg (i.e., first month 50%; second month 70%; third month 90% of the maximum dynamic strength). Group 2 will perform the same procedure, but the intensity will be maintained at 50% of the maximum dynamic strength throughout the treatment (i.e., constant intensity from the first to the third month). Group 3 will perform a 40-minute treadmill walk at low intensity, defined by a walking speed corresponding to 60-70% of the maximum heart rate, which we will control with a heart rate monitor. All groups will receive a 45-minute pain education session prior to the exercise program, covering the pathophysiologic mechanisms of chronic pain, strategies for coping with pain, avoiding hypervigilance, and deconstructing beliefs and myths about chronic pain. DISCUSSION: The results of the present study may help health care professionals adjust the intensity of resistance training and thus plan the most effective intervention (progressive or constant intensity) to reduce the impact of fibromyalgia on patients' lives.

Additional effect of pain neuroscience education to spinal manipulative therapy on pain and disability for patients with chronic low back pain: a randomized controlled trial.

BACKGROUND: Spinal manipulative therapy (SMT) demonstrates small effects on pain intensity in low back pain. Combining SMT with a psychosocial intervention like pain neuroscience education (PNE) could promote additional effect. OBJECTIVES: To evaluate the additional effect of PNE when combined to SMT on pain intensity and low back pain-related disability in patients with chronic low back pain (CLBP). METHOD: One hundred and four patients with CLBP of both sexes aged between 18 and 55 years were treated with PNE + SMT compared to SMT alone. The primary outcome measures were pain intensity and disability post-treatment (4 weeks). Secondary outcomes were fear-avoidance beliefs, global perceived effect of improvement, and pain self-efficacy. Results were obtained immediately post-treatment and at three follow-ups (30-days, 90-days, and 180-days). RESULTS: No significant between-group difference was observed for pain intensity and disability post-treatment. In contrast, our results showed a significantly longer additional effect for the group treated with SMT + PNE for the following outcomes: pain intensity (change baseline to 90 day follow-up = -0.90 [95% CI= -1.76, -0.4] and change baseline to 180 day follow-up = -1.19 [95% CI= -2.06, -0.32]) and low back pain-related disability, global perceived effect of improvement and pain self-efficacy (180th day follow-up). CONCLUSION: The results of this trial suggest the addition of PNE to SMT did not bring any additional effect on pain intensity and disability in the short term, but SMT + PNE can result in longer-lasting effects in patients with CLBP and that such an effect could be related to a possible mediator effect of pain self-efficacy.

Effect of high-intensity laser therapy in patients with non-specific chronic neck pain: study protocol for a randomized controlled trial.

BACKGROUND: Chronic non-specific neck pain (CNNP) is a prevalent musculoskeletal disorder known for its significant disability and economic burden, ranking second only to low back pain in musculoskeletal conditions. Physical therapy offers effective interventions for CNNP, including low-level laser therapy (LLLT). High-intensity laser therapy (HILT) is a recent treatment for musculoskeletal pain, but studies that support its use in CNNP are limited. The objective of this study is to assess the effect of high-intensity laser therapy on pain intensity in patients with CNNP, given the existing evidence on LLLT for this condition. METHODS: This is a 2-arm, randomized, placebo-controlled trial with blinded evaluators. The research will be carried out in the laboratory of physical agents at the Andrés Bello University, Campus Casona de las Condes. Eligible participants include the entire internal and external community associated with Andrés Bello University suffering from chronic non-specific NP. Participants will be stratified by sex (4 subgroups) and randomized into 2 study groups: group 1 (HILT and stretching exercises) and group 2 (sham HILT and stretching exercises). Treatments will be performed twice a week for 4 weeks with 3 assessments: before treatment (T0), at the end of treatment (T1), and 12 weeks after treatment (follow-up) (T2). The main outcomes will be pain intensity at rest, pain intensity at movement (active cervical movements: flexion, extension, right and left side bending, and right and left rotation), and pain pressure threshold (average obtained for six evaluation points). Secondary outcome measures will include neck range of motion in the sagittal, coronal, and transverse planes and neck disability. DISCUSSION: In this study, HILT's effects on patients with non-specific NP will be compared to those of a sham laser intervention. This RCT will offer new evidence regarding the potential benefits of HILT in terms of pain intensity, range of movement, and disability in people suffering with non-specific NP. TRIAL REGISTRATION: ClinicalTrials.gov NCT05689788. January 19, 2023.

Do the instruments used to assess fibromyalgia symptoms according to American College of Rheumatology criteria generate similar scores in other chronic musculoskeletal pain?

BACKGROUND: As with fibromyalgia, several musculoskeletal disorders are characterized by chronic pain, raising a clinical question - do the instruments used to assess fibromyalgia symptoms according to ACR criteria (ACR criteria) generate similar scores in other chronic musculoskeletal pain? OBJECTIVE: To compare the symptoms among fibromyalgia and other chronic musculoskeletal pain. Additionally, we also compared the most researched outcomes in fibromyalgia (i.e., present pain at rest and after movement; fatigue; pain severity and impact; function, global impact, and fibromyalgia symptom). METHODS: A cross-sectional study. Participants over 18 years old were included if they presented report of chronic musculoskeletal pain (≥ 3 months) and after that, they were divided into two groups (fibromyalgia and chronic pain). They answered the Fibromyalgia Impact Questionnaire-Revised (FIQ-R), Brief Pain Inventory (BPI), Numerical Pain Rating Scale (NPRS) for pain and fatigue, WPI, and SSS. RESULTS: A total of 166 participants were included in this study into two independent groups (chronic pain, n = 83; fibromyalgia, n = 83). We observed significant differences (p < 0.05) and large effect sizes (Cohen's d, ≥ 0.7) in clinical outcomes comparisons between groups (i.e., widespread pain; symptom severity; present pain at rest and after movement; fatigue; pain severity and impact; function, global impact, and fibromyalgia symptoms). CONCLUSION: Fibromyalgia patients (2016 ACR criteria) compared to other chronic musculoskeletal pain patients have higher levels of pain (at rest or after movement) and fatigue, greater impairment in both functionality and global impact, and worse symptoms. Therefore, the WPI and SSS instruments should be used exclusively to assess fibromyalgia symptoms.

Self-care during the COVID-19 pandemic: Development of a virtual educational booklet for postmenopausal women with osteoporosis.

OBJECTIVE: To describe the development of a virtual educational booklet for self-care promotion of postmenopausal women with osteoporosis during the COVID-19 pandemics. METHOD: This methodological study was conducted in three steps: bibliographic search, development of virtual educational booklet by 12 evaluators and ten representatives of the target audience. A questionnaire adapted from the literature was used to evaluate the educational booklet. The questionnaire consisted of seven items: scientific accuracy, content, language, illustrations, specificity and comprehension, readability, and quality of information. A minimum score of 0.75 in the content validity index (CVI) of each questionnaire item and minimum agreement of 75% among positive responses of postmenopausal women were required to validate the virtual booklet. RESULTS: Health professionals and representatives of the target audience suggested changes regarding layout, illustrations, and content of the virtual booklet. CVI of the final version was 0.84 between health professionals and agreement among the target audience was 90%. CONCLUSION: The virtual educational booklet with exercises and instructions for postmenopausal women with osteoporosis was valid and should be used by health professionals for advice on self-care and health promotion during the COVID-19 pandemic.

WHODAS measurement properties for women with dysmenorrhea.

BACKGROUND: There is an association of dysmenorrhea with human functioning and disability. However, no patient-reported outcome measure has been developed to assess this construct in women with dysmenorrhea. WHODAS 2.0 has been recognized as an important generic patient-reported outcome information of physical function and disability. Thus, the aim of this study was to assess the measurement properties of the WHODAS 2.0 in women with dysmenorrhea. METHODS: This is an online and cross-sectional study conducted with Brazilian women aged 14 to 42 years with self-report of dysmenorrhea in the last three months. According to COSMIN, structural validity was evaluated by exploratory and confirmatory factor analysis; internal consistency by Cronbach's Alpha; measurement invariance by multigroup confirmatory factor analysis between geographic regions of Brazil; and construct validity by correlating WHODAS 2.0 to the Numerical Rating Scale for pain severity. RESULTS: One thousand three hundred and eighty-seven women (24.7 ± 6.5 years) with dysmenorrhea participated in the study. WHODAS 2.0 presented a single factor by exploratory factor analysis and adequate model by confirmatory factor analysis (CFI = 0.924, TLI = 0.900, RMSEA = 0.038), excellent internal consistence (α = 0.892) for all items and an invariancy across geographic regions (ΔCFI ≤ 0.01 and ΔRMSEA < 0.015). Correlation between WHODAS 2.0 and numerical rating scale was positive and moderate (r = 0.337). CONCLUSION: WHODAS 2.0 has a valid structure to assess functioning and disability related to dysmenorrhea in women.

Social variables for replication of studies using mean scores of social support, self-care, and fibromyalgia knowledge: a cross-sectional study.

To investigate biopsychosocial variables that contribute to explaining social support, self-care, and fibromyalgia knowledge in patients with fibromyalgia. A cross-sectional study. We built ten models of predictive variables (schooling, ethnicity, associated diseases, body regions affected by pain, employment status, monthly income, marital status, health level, medication, sports activities, interpersonal relationships, nutrition level, widespread pain, symptom severity, cohabitation, dependent people, number of children, social support, self-care, and fibromyalgia knowledge) and individually tested their explanatory performance to predict mean scores on the Fibromyalgia Knowledge Questionnaire (FKQ), Medical Outcomes Study's Social Support Scale (MOS-SSS), and Appraisal of Self-Care Agency Scale-Revised (ASAS-R). We used analysis of variance to verify the association among all variables of mathematically adjusted models (F-value ≥ 2.20) and we reported only models corrected with p < 0.05 and R2 > 0.20. One hundred and ninety people with fibromyalgia (aged 42.3 ± 9.7 years) participated in the study. Our results show that the variables schooling, ethnicity, body regions affected by pain, frequency of sports activities, dependent people, number of children, widespread pain, social support, and self-care determine 27% of the mean FKQ scores. Marital status, self-care, and fibromyalgia knowledge determine 22% of mean MOS-SSS scores. Schooling, ethnicity, employment status, frequency of sports activities, nutrition level, cohabitation, number of children, social support, and fibromyalgia knowledge determine 30% of the mean ASAS-R scores. Studies using mean scores of social support, self-care, and fibromyalgia knowledge should collect and analyze the social variables described in the present study.

The Effects of Electrode Placement on Analgesia Using Transcutaneous Electrical Nerve Stimulation for Primary Dysmenorrhea: A Single-Blind Randomized Controlled Clinical Trial.

Background Primary dysmenorrhea (PD) refers to the occurrence of painful menstrual cramps without pathological involvement of the pelvic organs, with considerable morbidity and high prevalence among females of reproductive age. Objective The objective of this study is to present and test the efficacy of an innovative method of interactive transcutaneous electrical nerve stimulation (iTENS) for PD. Methods and materials This study is a single-blind controlled clinical trial. This was conducted at the outpatient clinic of the faculty of physical therapy. Females with PD (n=124) were divided into the treated group (transcutaneous electrical nerve stimulation {TENS} group {TG}, n=62) and the placebo group (PG, n=62). A single session of either iTENS or placebo intervention was used for 35 minutes. Pain, the duration of analgesia, and the use of pain medication were assessed before and after the intervention. Data from before and after the treatment were compared between groups (Student's t-test). The level of significance was set at 5%. Results A significant decrease in pain (p<0.001) was observed after the intervention for the TG, with a more long-lasting analgesia (p<0.001) and decreased need for pain medication (p<0.001). Conclusions The proposed method of transcutaneous electrical nerve stimulation (TENS) application showed positive results for pain management on females with PD, with no reported adverse effects. The new proposed TENS application takes into account the preferences of the patient regarding positioning and the number of channels needed to cause analgesia. This application was able to promote almost complete analgesia in females with primary dysmenorrhea, and the analgesia persisted for more than one menstrual cycle.

How does my pain look like? Characterizing dysmenorrhea-related pain using the body map / Como se parece a minha dor? Caracterizando a dor relacionada à dismenorreia utilizando o mapa corporal da dor

ABSTRACT BACKGROUND AND OBJECTIVES: Primary dysmenorrhea (PD) is a common gynaecological disorder characterized by pain in the abdominal region without pelvic disease. Evidence suggests that PD-related pain may not be restricted to the pelvis region, hence body mapping could be helpful in assessing the subjective location, intensity, and distribution of pain areas in women with PD. The objective of this study was to characterize dysmenorrhea-related pain location and intensity using body map. METHODS: We conducted a web-based cross-sectional study for adult women to self-report menstrual pain during three menstrual cycles. Each participant was instructed through a messaging application to paint the body map after printing it and rank their pain according to the 11-point Numerical Rating Scale. RESULTS: Seventy-three women (24.1 ± 3.0 years) participated in the study. A considerable proportion of participants reported pain in the lower abdomen (90.4%) and other body areas, such as the lower back (82.1%), head (54.6%), breasts (32.9%), upper abdomen (31.5%), and legs (28.8%). CONCLUSION: Our findings revealed that women with PD also present pain outside the uterine referral area during their period. In this way, body maps can help healthcare professionals to record specific regions of pain and track changes or patterns in the location or intensity pain during menses, helping to determine treatment strategies appropriate to the individual needs of each woman with PD. Therefore, we strongly recommend the clinical use of the self-report body map to evaluate menstrual pain and help health providers to improve PD symptoms in this population.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dismenorreia primária (DP) é um distúrbio ginecológico comum caracterizado por dor na região abdominal sem doença pélvica. Evidências sugerem que a dor relacionada à DP pode não estar restrita à região da pelve, portanto, o mapeamento corporal pode ser útil para avaliar a localização subjetiva, a intensidade e a distribuição das áreas de dor em mulheres com DP. O objetivo deste estudo foi caracterizar a localização e a intensidade da dor relacionada à dismenorreia por meio do mapa corporal. MÉTODOS: Conduziu-se um estudo transversal baseado na web para mulheres adultas para autorrelato de dor menstrual durante três ciclos menstruais. Cada participante foi instruído por meio de um aplicativo de mensagens a pintar o mapa corporal após imprimi-lo e classificar sua dor de acordo com a Escala de Avaliação Numérica de 11 pontos. RESULTADOS: Setenta e três mulheres (24,1±3,0 anos) participaram do estudo. Uma proporção considerável de participantes relatou dor na parte inferior do abdômen (90,4%) e em outras áreas do corpo, como a parte inferior das costas (82,1%), cabeça (54,6%), mamas (32,9%), parte superior do abdômen (31,5%) e pernas (28,8%). CONCLUSÃO: Os presentes achados revelaram que mulheres com DP também apresentam dor fora da área de referência uterina durante o período menstrual. Dessa forma, os mapas corporais podem ajudar os profissionais de saúde a registrar regiões específicas de dor e rastrear mudanças ou padrões na localização ou intensidade da dor durante a menstruação, ajudando a determinar estratégias de tratamento adequadas às necessidades individuais de cada mulher com DP. Portanto, recomenda-se fortemente o uso clínico do mapa corporal de autorrelato para avaliar a dor menstrual e ajudar os profissionais de saúde a melhorar os sintomas de DP nessa população.

Women with fibromyalgia (ACR criteria) compared with women diagnosed by doctors and women with osteoarthritis: Cross-sectional study using functional and clinical variables.

PURPOSE: To compare functional and clinical variables of women with fibromyalgia (American College of Rheumatology [ACR] criteria) vs women diagnosed by doctors and women with knee osteoarthritis (KOA). METHODS: This is a cross-sectional study. We used clinical measures, namely, Widespread Pain Index (WPI), Symptom Severity Scale (SSS), Fibromyalgia Impact Questionnaire-Revised (FIQ-R), Numerical Pain Rating Scale (NPRS), Central Sensitization Inventory (CSI), Pain-Related Catastrophizing Thoughts Scale (PCTS), and functional measures, such as Sit-to-Stand (STS) test, and Timed Up and Go (TUG) test. RESULTS: The sample consisted of 91 participants divided into 3 groups: participants with KOA (n = 30), fibromyalgia diagnosed according to the ACR (FM-ACR, n = 31), and fibromyalgia according to the medical diagnosis (FM-Med, n = 30). In the comparisons, we observed a significant difference (P < 0.05) and a large effect size (d ≥ 0.8), between all groups, in the WPI, WPI + SSS, FIQ-R domains, CSI, and PCTS. We did not observe significant values in the correlations between the clinical variables, SST, and TUG test. CONCLUSION: People with fibromyalgia according, to the ACR, have higher levels of widespread pain, symptom severity, global impact on quality of life, central sensitization, and catastrophizing compared with people with knee OA and people with clinical fibromyalgia diagnosis not confirmed by the ACR diagnostic criteria.

The best structure of the Tampa Scale for Kinesiophobia for patients with chronic low back pain has two domains and nine items.

PURPOSE: To identify the best internal structure of the Tampa Scale for Kinesiophobia in chronic low back pain patients. DESIGN: Questionnaire validation study was designed for this study. SETTING: This study was conducted in physical therapy facility. SUBJECTS: Respondents reporting chronic low back pain (≥3 points on the 11-point Numerical Pain Rating Scale). MAIN MEASURES: We included participants of both sexes, with a self-report of low back pain ≥3 months and with pain intensity ≥3 on the 11-point Numerical Pain Rating Scale; participants also answered the Roland-Morris Disability Questionnaire and the Pain-Related Catastrophizing Thoughts Scale for low back pain disability and catastrophizing, respectively. The dimensionality and number of items of the Tampa Scale for Kinesiophobia were evaluated using the confirmatory factor analysis. Criterion validity was assessed using Spearman's correlation coefficient using the original version of the 17-item Tampa Scale for Kinesiophobia as the gold standard. RESULTS: A total of 122 participants were included, with mean values of low back pain duration ≥48 months, pain intensity >5 and disability >8. Tampa Scale for Kinesiophobia structure with two domains and nine items was the most suitable, with adequate values in all fit indices (Chi-square/degree of freedom <3, Comparative Fit Index and Tucker-Lewis Index >0.90, and root mean square error of approximation <0.08) and lower Akaike information criterion and Bayesian information criterion values. We observed a high correlation between the 17-item Tampa Scale for Kinesiophobia and the activity avoidance domain (rho = 0.850, P < 0.001) and somatic focus domain (rho = 0.792, P < 0.001) of the nine-item Tampa Scale for Kinesiophobia. CONCLUSION: Tampa Scale for Kinesiophobia structure with two domains (activity avoidance and somatic focus) and nine items is the most suitable for patients with chronic low back pain.

Ten-Item Lower Extremity Functional Scale (LEFS-10): Instrument Reduction Based on Brazilian Patients With Lower Limb Dysfunction.

OBJECTIVE: To propose a short version of the lower extremity functional scale (LEFS), to compare our short version with the different structures proposed for the LEFS by the specialized literature, and to verify the criterion validity of the best structure of the LEFS identified in our study. DESIGN: Cross-sectional observational study. SETTING: Physiotherapy clinics. PARTICIPANTS: We included 140 patients with lower limb dysfunction (N=140). INTERVENTIONS: None. MAIN OUTCOME MEASURES: We used confirmatory factor analysis (CFA), χ2/degree of freedom (DF), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), standardized root mean squared residual (SRMR), Akaike information criterion (AIC), and Bayesian information criterion (BIC). The method of reducing the number of items of the LEFS considered the modification indices and factor loadings. RESULTS: The body site most affected by pain was the knee (71.4%), and the most common diagnoses were knee osteoarthritis (55%) and anterior knee pain (11.4%). LEFS reduction generated a 1-dimensional structure of the LEFS with 10 items (LEFS-10). When compared with other structures, the LEFS-10 presented the best fit indices (χ2/DF=1.88, CFI=0.975, TLI=0.968, RMSEA=0.079, and SRMR=0.058) and the lowest values of AIC (3287.063) and BIC (3345.896). LEFS-10 presents a high correlation (Spearman's correlation coefficient [ρ]=0.911, P<.001) with the 20-item LEFS. CONCLUSION: LEFS-10 is the proposal for a short version of the instrument with the most adequate internal structure, in addition to being satisfactorily correlated with the longer version of the instrument.

Educação em neurociência da dor e Pilates para idosos com dor lombar crônica: ensaio clínico controlado randomizado / Educación en neurociencia del dolor y pilates para personas mayores con dolor lumbar crónico: ensayo clínico controlado aleatorizado / Pain neuroscience education and pilates for elderly with chronic low back pain: randomized controlled clinical trial

Resumo Objetivo Avaliar o efeito da Educação em Neurociência da Dor aliada ao Pilates na catastrofização da dor em idosos com lombalgia crônica inespecífica. Métodos Ensaio clínico controlado randomizado com 80 participantes divididos em dois grupos: Grupo Pilates combinado com Educação em Neurociência da Dor - GPE, e Grupo Pilates- GP. As medidas foram feitas no início, pós-intervenção e após seis meses (seguimento). O protocolo incluiu três sessões individuais de Educação em Neurociência da Dor (END) de 30 min (somente para o GPE) e, posteriormente, oito semanas de Pilates (duas vezes por semana, 50 min/sessão, para ambos os grupos). Resultados Comparações das diferenças pré-pós e de seguimento em catastrofização, cinesiofobia, incapacidade e intensidade da dor não mostraram evidências de que a END teve efeitos adicionais em comparação com os exercícios isoladamente. Uma vantagem provável do presente protocolo de END foi que as taxas de abandono para o GPE foram menores do que para o GP, mostrando que a END aumentou a adesão ao exercício. Conclusão A relevância clínica do estudo é que o Pilates é uma intervenção segura para idosos com dor lombar crônica inespecífica e a END pode aumentar a adesão ao exercício nessa população.

Resumen Objetivo Evaluar el efecto de la educación en neurociencia del dolor como aliada a la práctica de pilates en la catastrofización del dolor en personas mayores con lumbalgia crónica inespecífica. Métodos Ensayo clínico controlado aleatorizado con 80 participantes divididos en dos grupos: Grupo pilates combinado con educación en neurociencia del dolor (GPE) y Grupo pilates (GP). Las medidas se realizaron antes y después de la intervención y después de seis meses (seguimiento). El protocolo incluía tres sesiones individuales de educación en neurociencia del dolor (END) de 30 minutos (solo para el GPE) y, posteriormente, ocho semanas de pilates (dos veces por semana, 50 min/sesión, para ambos grupos). Resultados La comparación de las diferencias antes-después y de seguimiento en catastrofización, kinesiofobia, incapacidad e intensidad del dolor no mostró evidencias de que la END tenga efectos adicionales en comparación con los ejercicios de forma aislada. Una ventaja probable del presente protocolo de END fue que los índices de abandono del GPE fueron menores que en el GP, lo que demuestra que la END aumentó la adherencia al ejercicio. Conclusión La relevancia clínica del estudio es que pilates es una intervención segura para personas mayores con dolor lumbar crónico inespecífico y la END puede aumentar la adherencia al ejercicio en esta población.

Abstract Objective Verify the effect of Pain Neuroscience Education combined with Pilates on catastrophizing in older people with chronic non-specific low back pain. Methods A randomized controlled clinical trial with 80 participants divided into two groups: Pilates combined with Pain Neuroscience Education Group - PEG, and Pilates Group - PG. The measurements were taken at baseline, post-intervention, and after 6 months (follow-up). The protocol included three individual 30-min PNE sessions (only for PEG) and, after that, 8 weeks of Pilates (twice a week, 50 min/session, for both groups). Results Comparisons of pre-post and follow-up differences in catastrophizing, kinesiophobia, disability, and pain intensity showed no evidence that PNE had any additional effects when compared with exercises alone. One likely advantage of the present PNE protocol was that the dropout rates for the PEG group were lower than for the PG group, showing that PNE has increased exercise adherence. Conclusion The clinical relevance of the study is that Pilates is a safe intervention for older people with non-specific chronic low back pain, and that PNE can increase adherence to exercise for this population.
