Impact of chronic illness caused by chikungunya fever on quality of life and functionality.

BACKGROUND: Chikungunya fever compromises the functionality and quality of life in the affected individuals, even one year after the acute phase of the disease. Chronically affected people experience direct impairment in performing daily activities, along with a risk of developing other morbidities. BACKGROUND: ◼ Even after a year, chikungunya fever-affected people experience damage to their physical and mental health. BACKGROUND: ◼ Positive screening for depression risk was 13.5 times more likely in chronically affected. BACKGROUND: ◼ Patients with chronic chikungunya fever had a 76 times higher risk of walking impairments. OBJECTIVE: To evaluate the impact of chronic illness caused by chikungunya fever on the quality of life and functionality of affected individuals. METHODS: A cross-sectional and comparative study was conducted in which two groups were investigated: a Chikungunya Group comprising 25 patients with chronic fever screened after 1 year of illness via a telephonic survey, and a Healthy Group comprising 25 healthy individuals matched for sex and age by face-to-face interview. The Stanford HAQ 20-Item Disability Scale (HAQ) and the Short Form Health Survey (SF-12) questionnaires were administered to both groups. Generalized Linear Models, Pearson χ2 tests, and odds ratios were used to evaluate the test results. RESULTS: Significant differences in functional capacity and quality of life were observed between the Chikungunya and Healthy Groups. The chance of some impairment in functionality was also much higher in the Chikungunya Group in four of the HAQ categories, especially in the "walking" category (adjusted OR= 109.40). Further, the Chikungunya Group had a higher chance of presenting a below-average score in the mental component summary of the SF-12 (adjusted OR= 16.20) and of being positive in depression risk screening (adjusted OR= 34.57). CONCLUSION: Even one year after the acute phase, chikungunya fever can compromise the functionality and quality of life in affected individuals, with direct impairment in performing daily activities. Studies and therapeutic plans for chikungunya fever should consider the long-term impacts of this disease.

Neural respiratory drive during maximal voluntary ventilation in individuals with hypertension: A case-control study.

Neural respiratory drive (NRD) is measured using a non-invasive recording of respiratory electromyographic signal. The parasternal intercostal muscle can assess the imbalance between the load and capacity of respiratory muscles and presents a similar pattern to diaphragmatic activity. We aimed to analyze the neural respiratory drive in seventeen individuals with hypertension during quite breathing and maximal voluntary ventilation (MVV) (103.9 ± 5.89 vs. 122.6 ± 5 l/min) in comparison with seventeen healthy subjects (46.5 ± 2.5 vs. 46.4 ± 2.4 years), respectively. The study protocol was composed of quite breathing during five minutes, maximum inspiratory pressure followed by maximal ventilatory ventilation (MVV) was recorded once for 15 seconds. Anthropometric measurements were collected, weight, height, waist, hip, and calf circumferences, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), BMI, and conicity index (CI). Differences between groups were analyzed using the unpaired t-test or Mann-Whitney test to determine the difference between groups and moments. A significance level of 5% (p<0,05) was adopted for all statistical analyses. The group of individuals with hypertension presented higher values when compared to the healthy group for neural respiratory drive (EMGpara% 17.9±1.3 vs. 13.1±0.8, p = 0.0006) and neural respiratory drive index (NRDi (AU) 320±25 vs. 205.7±15,p = 0.0004) during quiet breathing and maximal ventilatory ventilation (EMGpara% 29.3±2.7 vs. 18.3±0.8, p = 0.000, NRDi (AU) 3140±259.4 vs. 1886±73.1,p<0.0001), respectively. In conclusion, individuals with hypertension presented higher NRD during quiet breathing and maximal ventilatory ventilation when compared to healthy individuals.

Exploring patient experiences of participating in a real and sham dry cupping intervention for nonspecific low back pain: A qualitative study.

BACKGROUND: The current quality of evidence supporting dry cupping for individuals with chronic low back pain (CLBP) is low and suggests that nonspecific factors impact experiences reported by patients. Therefore, this study assessed the impacts of social and professional support on the experience of individuals with CLBP treated with dry cupping or sham. METHOD: This is an observational study with qualitative approach. Twenty-four individuals with CLBP who received dry cupping or sham in a previous clinical trial were invited. Data was collected using a semi-structured interview conducted by a trained researcher. Content analysis was used to analyze experiences, systematic procedures, and description of the content of messages. The dimensions of "pain", "general perceptions", and "perceived social and professional support" guided the analysis. RESULTS: Answers of both groups converged on similar perceptions, especially regarding pain. Physical condition was the most fragile aspect. We also observed an influence of perceived social and professional support on painful symptoms. Thus, the experience of individuals with CLBP treated with dry cupping or sham indicated that factors related to social and professional support impacted results. CONCLUSIONS: We observed that individuals with CLBP reported similar perceptions of the effects of dry cupping or sham treatment, indicating that contextual factors may influence the perception of these individuals regarding the treatment received.

Dry cupping therapy is not superior to sham cupping to improve clinical outcomes in people with non-specific chronic low back pain: a randomised trial.

QUESTION: What are the effects of dry cupping on pain intensity, physical function, functional mobility, trunk range of motion, perceived overall effect, quality of life, psychological symptoms and medication use in individuals with chronic non-specific low back pain? DESIGN: Randomised controlled trial with concealed allocation, intention-to-treat analysis and blinding of participants and assessors. PARTICIPANTS: Ninety participants with chronic non-specific low back pain. INTERVENTIONS: The experimental group (n = 45) received dry cupping therapy, with cups bilaterally positioned parallel to the L1 to L5 vertebrae. The control group (n = 45) received sham cupping therapy. The interventions were applied once a week for 8 weeks. OUTCOME MEASURES: Participants were assessed before and after the first treatment session, and after 4 and 8 weeks of intervention. The primary outcome was pain intensity, measured with the numerical pain scale at rest, during fast walking and during trunk flexion. Secondary outcomes were physical function, functional mobility, trunk range of motion, perceived overall effect, quality of life, psychological symptoms and medication use. RESULTS: On a 0-to-10 scale, the between-group difference in pain severity at rest was negligible: MD 0.0 (95% CI -0.9 to 1.0) immediately after the first treatment, 0.4 (95% CI -0.5 to 1.5) at 4 weeks and 0.6 (95% CI -0.4 to 1.6) at 8 weeks. Similar negligible effects were observed on pain severity during fast walking or trunk flexion. Negligible effects were also found on physical function, functional mobility and perceived overall effect, where mean estimates and their confidence intervals all excluded worthwhile effects. No worthwhile benefits could be confirmed for any of the remaining secondary outcomes. CONCLUSION: Dry cupping therapy was not superior to sham cupping for improving pain, physical function, mobility, quality of life, psychological symptoms or medication use in people with non-specific chronic low back pain. PROTOCOL REGISTRATION NUMBER: NCT03909672.

Does current evidence support the use of kinesiology taping in people with knee osteoarthritis?

OBJECTIVE: To analyze the current evidence about the effects of kinesiology taping (KT) with different amounts of tension in people with knee osteoarthritis (OA). DATA SOURCES: MEDLINE (via PUBMED), SciELO, COCHRANE Library, Scopus, PEDro, Web of Science and EMBASE were used as search databases. STUDY SELECTION: Two independent researchers searched these databases from inception until June 2020 using the descriptors "kinesiotaping", "kinesio taping", "kinesiotape", "tape", "taping", "kinesiology taping", "kinesiology tape", "kinesthetic taping" or "elastic therapeutic tape" associated with "knee osteoarthritis". We included clinical trials that compared the application of KT with and without tension in people with knee OA. DATE EXTRACTION AND QUALITY ANALYSIS: Data extraction included sample description, KT tension used in the study groups, duration of KT application, area of KT application, outcome measures and study methodological quality. The quality of the studies was evaluated by means of the Physiotherapy Evidence Database (PEDro) score. DATA SYNTHESIS: Of the 850 studies identified, eight met the inclusion criteria and were ultimately included in this review. Most studies had moderate quality, with a satisfactory PEDro score. Results showed that KT application with tension was not superior to the application without tension for the outcomes of pain, physical function, range of motion and muscle strength. Evidence for edema, balance and quality of life is still limited. CONCLUSION: Current evidence does not support the use of kinesiology taping in people with knee OA.

Effects of dry cupping on pain, function and quality of life in women with knee osteoarthritis: a protocol for a sham-controlled randomised trial.

INTRODUCTION: Knee osteoarthritis (KOA) is the most common cause of pain and disability worldwide. Dry cupping has been used as non-pharmacological approach to control pain and improve physical function. However, there is a lack of high-quality scientific evidence regarding its effects on this condition. This protocol describes a sham-controlled, randomised and simple blind study that aims to evaluate the effect of dry cupping on pain, function and quality of life in women with KOA. METHODS AND ANALYSIS: Sixty-two women diagnosed with KOA, based on American College of Rheumatology clinical criteria, and aged from 50 to 75 years, will be randomly distributed into two groups (31 per group): real and sham dry cupping. Both applications will occur with acrylic cups around the knee. The intervention will last 15 min, two times a week over six consecutive weeks, for a total of 12 sessions. Both groups will be assessed at four different times: before the intervention (T0), after 3 weeks intervention (T3), at the end of the protocol (T6) and 4 weeks after the interventions (follow-up: T10). The primary outcome will be pain intensity (Numerical Pain Rating Scale), and secondary outcomes will be knee-related health status (Western Ontario and McMaster Universities Osteoarthritis Index), functional capacity (8-step stair climb test, 40-metre fast-paced walk test and 30-second chair stand test), quality of life (Short-Form 36) and global perceived effect. ETHICS AND DISSEMINATION: This protocol was approved by the UFRN/FACISA Ethics Committee (number 3.737.688). The study results will be disseminated to the participants and submitted to a peer-reviewed journal and scientific meetings. TRIAL REGISTRATION NUMBER: NCT04331158.

Does tension applied in kinesio taping affect pain or function in older women with knee osteoarthritis? A randomised controlled trial.

OBJECTIVE: To analyse the short-term effects of kinesio taping (KT) with tension (KTT) or without tension (KTNT) in older women with knee osteoarthritis (KOA), and compare them to controls who did not receive KT. DESIGN: Randomised controlled trial. SETTING: University physiotherapy school clinic. PARTICIPANTS: Forty-five older women (fifteen participants per group) with 66.8 (±5.6) years and clinical diagnosis of KOA were assessed pre, post and 3 days after intervention. INTERVENTIONS: Participants were randomly allocated to KTT, who received two simultaneous applications of KT with tension on the knee and rectus femoris; KTNT, who received the same application as the KTT group, but without tension and a control group that attended a class on KOA. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was pain intensity and secondary outcomes were knee-related health status, functional capacity, muscle strength and global rating of change. RESULTS: No between-group differences were observed in pain after the first intervention (KTT vs KTNT: mean difference (MD), -1.8 points; 95% CI -4.2 to 0.5; KTT vs control: MD, -1.2 points; 95% CI -3.6 to 1.2; KTNT vs control: MD, 0.66 points; 95% CI -1.7 to 3.0) or 3 days later (KTT vs KTNT: MD, -1.3 points; 95% CI -3.7 to 1.0; KTT vs control: MD, 0.13 points; 95% CI -2.2 to 2.5; KTNT vs control: MD, 1.4 points; 95% CI -0.9 to 3.8). The lack of between-group differences was also found for secondary outcomes. CONCLUSION: The short-term use of KT with or without tension in older woman with KOA had no beneficial effects on pain and function. These findings call into question the clinical use of KT as a non-pharmacological therapy for this population. TRIAL REGISTRATION NUMBER: NCT03624075.

Main types of insoles described in the literature and their applicability for musculoskeletal disorders of the lower limbs: A systematic review of clinical studies.

The objective of this review was to identify the main types of insoles described in the literature that are used to treat musculoskeletal alterations of lower limbs and to analyze the existence of previous evaluation for the prescription of these insoles. To this end, two researchers, independently and blindly, searched the PubMed, SciELO, Bireme, MEDLINE, Lilacs, PEDro, Cochrane Library and Web of Science databases between June and July of 2018, from the free combination of the following descriptors: insoles, foot orthoses, foot, orthoses, musculoskeletal diseases and clinical trial. We included randomized or non-randomized clinical trials in which at least one intervention group used insoles and individuals with some type of musculoskeletal disorder had been sampled. Of the 227 documents identified in date bases, 20 were included in this review. In general, it is suggested to carry out more studies with more precise methods and that include evaluation before the prescription. This is a systematic review of clinical trials registered in PROSPERO (International Prospective Register of Systematic Reviews) under the protocol no. CRD42018099534e.

Mat Pilates is as effective as aquatic aerobic exercise in treating women with fibromyalgia: a clinical, randomized and blind trial.

BACKGROUND: The mat Pilates method is the therapeutic modalities which can be used in fibromyalgia treatment. Although there are no well-designed studies that prove the effectiveness of the mat Pilates method in this population. The objective was to evaluate the effectiveness of the mat Pilates method for improving symptoms in women with fibromyalgia. METHODS: A single blind randomized controlled trial in which 42 women with fibromyalgia were randomized into two groups: mat Pilates and aquatic aerobic exercise. The exercises were performed twice a week for 12 weeks. Two evaluations were performed: one at baseline (T0), and another at 12 weeks after randomization (T12). The primary outcome was pain measured by the Visual Analogue Scale (VAS). Secondary outcomes were function (Fibromyalgia Impact Questionnaire), sleep (Pittsburgh Sleep Quality Index [PSQI]), quality of life (Short Form 36 [SF-36]), fear avoidance (Fear Avoidance Beliefs Questionnaire [FABQ-BR]) and pain catastrophizing (Pain-Related Catastrophizing Thoughts Scale [PRCTS]). RESULTS: There was improvement in both groups in relation to pain and function (p < 0.05). The aspects related to quality of life and the FABQ questionnaire only showed improvement in the mat Pilates group (p < 0.05). There was improvement in the PSQI and PRCTS variables only in the aquatic aerobic exercise group (p < 0.05), but no differences were observed between the groups for any of the evaluated variables. CONCLUSION: Significant improvements were observed in the two groups in relation to the disease symptoms, and no differences were observed between mat Pilates and aquatic aerobic exercise in any of the measured variables.

OBJECTIVE: To evaluate the effects of insoles adapted into flip-flop sandals on pain and function in individuals with plantar fasciopathy (PF). DESIGN: Randomized, double-blind controlled study. SETTING: Physiotherapy clinic of the Faculty of Health Sciences of Trairi, Federal University of Rio Grande do Norte, Santa Cruz, Brazil. SUBJECTS: Sixty-six patients of both genders with PF were randomized into two groups: sandal insole group (SI; n = 34), which received a pair of custom flip-flop sandals with insoles covered with smooth synthetic leather; and plain sandal group (PS; n = 32), which received an identical pair of flip-flop sandals, but without the insoles. INTERVENTIONS: Patients were instructed to wear the flip-flops for 12 weeks for at least 4 hours/day. MAIN MEASURES: Pain (visual analogue scale-VAS) in the morning and at the end of the day were considered primary outcomes. Function (Foot Function Index-FFI and Foot and Ankle Ability Measure-FAAM) and functional capacity (6-minute walk test-6MWT) were considered secondary outcomes. The outcomes were evaluated at baseline and immediately after the intervention by a blind assessor. RESULTS: Between-group differences were observed in terms of morning pain (mean difference (MD) = -1.82 cm; 95% confidence interval (CI) = -3.3 to -0.3; P = 0.016) and function (MD = -0.10; 95% CI = -0.19 to -0.01; P = 0.023) after the interventions with the SI group showing superior improvements in comparison to the PS group. CONCLUSION: The use of insoles adapted in flip-flop sandals for 12 weeks was effective at improving pain and function in individuals with PF. LEVEL OF EVIDENCE: 1b.

Dry cupping in the treatment of individuals with non-specific chronic low back pain: a protocol for a placebo-controlled, randomised, double-blind study.

BACKGROUND: Low back pain is a very prevalent condition in the population and cupping therapy has been presented as a frequently used non-pharmacological treatment in this population. However, there is a lack of well-designed studies that evaluate the effects of this technique. This protocol describes a placebo-controlled, randomised, double-blind study that aims to evaluate the effect of dry cupping therapy on pain, physical function, trunk range of motion, quality of life and psychological symptoms in individuals with non-specific chronic low back pain. METHODS AND ANALYSIS: Ninety individuals with chronic non-specific low back pain, aged from 18 to 59 years, will be randomised into two groups: intervention group, which will be submitted to dry cupping therapy application with two suctions; and placebo group which will undergo placebo dry cupping therapy. Both applications will occur bilaterally in parallel to the vertebrae from L1 to L5. The application will be performed once a week for 8 weeks. The volunteers will be evaluated before the treatment (T0), immediately after the first intervention (T1), after 4 weeks of intervention (T4) and after 8 weeks of intervention (T8). The primary outcome will be pain intensity, and secondary outcomes will be physical function, lumbar range of motion, patient expectation, overall perception of effect, quality of life and psychological factors. ETHICS AND DISSEMINATION: This protocol has been approved by the Ethics Committee of FACISA/UFRN (number: 3639814). The results of the study will be disseminated to participants through social networks and will be submitted to a peer-reviewed journal and scientific meetings. TRIAL REGISTRATION NUMBER: NCT03909672.

Assessment of quality of movement during a lateral step-down test: Narrative review.

INTRODUCTION: Altered lower limb movement patterns during weight-bearing activities have been described as risk factors for several injuries. The lateral step-down test (LSD) was developed to be a simple, clinician-friendly tool to facilitate the assessment of lower extremity quality of movement during a functional activity. However, there is still conflicting information across the literature regarding how the LSD should be performed. OBJECTIVE: To critically review the literature regarding the assessment of quality of movement using the LSD and to provide an overview of how this test has been used, describing confounding factors and factors associated with altered movement patterns. METHODS: A literature review was conducted in PubMed/MEDLINE, COCHRANE, PEDro, SciELO and LILACS databases, by two independent reviewers. RESULTS: Sixteen articles met the inclusion criteria. One was a prospective cohort study to identify risk factors for injuries in military recruits. The fifteen remaining were cross-sectional studies involving healthy military recruits, physically active individuals, athletes and/or sedentary subjects, as well as participants with knee and ankle disorders. Worst quality of movement during the LSD has been associated with deficits in hip external rotation and knee extension strength as well as in ankle dorsiflexion range of motion. The reliability of the LSD has been reported to be moderate (κ = 0.59-0.81). CONCLUSIONS: The LSD has adequate reliability and is a simple tool that can be used to quantify lower extremity quality of movement. Future studies should include standardized methods for application, scoring and interpretation of the test, so that confounding factors can be minimized.

Clinical and self-perceived oral health assessment of elderly residents in urban, rural, and institutionalized communities.

OBJECTIVES: This study aims to evaluate the self-perception of oral health according to the physical, psychosocial and pain/discomfort dimensions related to clinical conditions and orofacial pain of elderly people living in three different environments. METHODS: This was an observational, cross-sectional, quantitative study with a population-based approach and nonprobabilistic convenience sampling that included 81 elderly people: 27 resided in institutional homes for elderly individuals, 27 resided in an urban area and 27 resided in a rural area in the interior of Paraíba (PB) in northeastern Brazil. RESULTS: The Geriatric Oral Health Assessment Index (GOHAI) was used to assess self-perception of oral health, while the Questionnaire for Screening of Patients with Temporomandibular Disorders (QST/TMD) was used to assess the influences of orofacial pain and the biofilm indexes of teeth and prostheses. There was a statistically significant difference in the GOHAI scores among the places of residence, with the worst values associated with the rural area. According to the QST/TMD, the majority of individuals were affected by TMDs, with statistical differences for both sex and income. CONCLUSION: The biofilm analysis showed a higher incidence of clinical conditions in the rural population. The place of residence also influenced self-perception and the clinical oral health condition of elderly people; the rural population presented the worst results.

Sophrology versus resistance training for treatment of women with fibromyalgia: A randomized controlled trial.

INTRODUCTION: Physical training has been recommended to improve overall well-being in patients with fibromyalgia. Body relaxation exercises also seem to have some beneficial effect, however there is no consensus regarding this modality. OBJECTIVE: Comparing the effectiveness of sophrology and resistance training in improving the pain of women with fibromyalgia. METHOD: A randomized controlled clinical trial with a blind evaluator. Sixty (60) women with a medical diagnosis of fibromyalgia were randomized and included in two groups: sophrology group (SG) who participated in a relaxation program based on sophrology (n = 30), and resistance group (RG) (n = 30) who participated in a resistance training program for biceps, pectoral, triceps, knee extensors, trapezius, knee flexors, hip abductors. Both groups were treated twice a week for 12 weeks and reevaluated every 4 weeks. The assessment instruments used were the Visual Analog Scale for Pain (VAS), the one-repetition maximum test (1 RM), the overall quality of life (SF-36), the 6-min walk test (6MWT), the Timed Up and Go test (TUG) and the Fibromyalgia Impact Questionnaire (FIQ). RESULTS: We found that the RG presented statistically significant decreases in pain (VAS) during the evaluations (p < 0.05) and increased strength of the evaluated muscles (p < 0.05). A statistically significant decrease in pain (p < 0.05) was observed in the SG compared to T0, with no significant differences in muscle strength. Differences between groups were observed, with better indices only for 6MWT and functional capacity domain of the SF36 for the RG (p < 0.05). CONCLUSION: No differences in pain were found between the groups. Resistance training was more effective than sophrology in improving strength and functional capacity of women with fibromyalgia.

Mat Pilates and aquatic aerobic exercises for women with fibromyalgia: a protocol for a randomised controlled blind study.

INTRODUCTION: Physical exercises have been recommended to improve the overall well-being of patients with fibromyalgia, with the main objective of repairing the effects of lack of physical conditioning and of improving the symptoms, especially pain and fatigue. Although widely recommended and widely known, few studies support the use of Pilates as an effective method in improving the symptoms of the disease, comparing it with other well-founded exercise modalities. This protocol was developed to describe the design of a randomised controlled study with a blind evaluator that evaluates the effectiveness of mat Pilates, comparing it with aquatic aerobic exercises, in improving pain in women with fibromyalgia. METHODS: Sixty women aged 18-60 years with a diagnosis of fibromyalgia, with a score of between 3 and 8 points on the Visual Analogue Scale for pain, and who sign the clear and informed consent form will be recruited according to the inclusion criteria. They will be randomised into one of the two intervention groups: (1) Pilates, to perform an exercise programme based on mat Pilates; and (2) aquatic exercise, to participate in a programme of aerobic exercises in the swimming pool. The protocol will correspond to 12 weeks of treatment, with both groups performing the exercises with supervision twice a week. The primary outcome will be pain (Visual Analogue Scale for pain). The secondary outcomes are to include impact related to the disease, functional capacity, sleep quality and overall quality of life. The evaluations will be performed at three points: at baseline and after 6 weeks and 12 weeks of treatment. ETHICS AND DISSEMINATION: This protocol has been approved by the Ethics Committee of FACISA/UFRN (number: 2.116.314). Data collection will begin after approval by the ethics committee. There will be prior contact with the women, at which time all the information about the study and the objectives will be presented, as well as resolution no 466/2012 of the National Health Council of Brazil for the year 2012, which provides guidelines and regulatory standards for research involving human beings. Participants must sign the informed consent form before the study begins. TRIAL REGISTRATION NUMBER: NCT03149198.

Whole-Body Vibration on Performance of Quadriceps After ACL Reconstruction: A Blinded Randomized Controlled Trial.

CONTEXT: Whole-body vibration (WBV) has been widely used in clinical and sport practice. These devices produce constant vibrations, originating symmetrical waves that move along the vertical axis. It is suggested that mechanical stimuli produced by high vibration can be an alternative to improve neuromuscular performance and balance in different populations. However, there is still a lack of consensus in the literature regarding neurophysiological responses in the skeletal muscle immediately after the use of WBV, specifically in individuals subjected to anterior cruciate ligament reconstruction. OBJECTIVE: To investigate the immediate effects of WBV on neuromuscular performance of the quadriceps femoris and postural oscillation of individuals subjected to anterior cruciate ligament reconstruction. DESIGN: This is a blinded randomized controlled trial. SETTING: University laboratory. PARTICIPANTS: Forty-four men. INTERVENTION: Participants were randomized into 2 groups: control group (n = 22, exercise protocol on the vibrating platform turned off) and WBV group (n = 22, exercises on the vibrating platform turned on, at a frequency of 50 Hz and amplitude of 4 mm). MAIN OUTCOME MEASURES: The volunteers underwent a dynamometric evaluation of the quadriceps femoris and electromyographic activity of vastus lateralis and vastus medialis muscles, in addition to oscillation of the center of pressure at 2 different moments: before and immediately after the intervention protocol. RESULTS: The intragroup comparison evidenced differences between preassessments and postassessments for the variables of laterolateral amplitude, peak torque, and total work. However, no significant difference was observed in the intergroup comparison after WBV protocol. CONCLUSION: The use of WBV did not immediately alter the performance of the quadriceps femoris and the electromyographic activity of vastus lateralis and vastus medialis muscles. In addition, it also did not interfere with pressure center oscillation of individuals subjected to anterior cruciate ligament reconstruction.

There was a statistically significant difference in the GOHAI scores among the places of residence, with the worst values associated with the rural area. According to the QST/TMD, the majority of individuals were affected by TMDs, with statistical differences for both sex and income. CONCLUSION: The biofilm analysis showed a higher incidence of clinical conditions in the rural population. The place of residence also influenced self-perception and the clinical oral health condition of elderly people; the rural population presented the worst results.

Zumba dancing can improve the pain and functional capacity in women with fibromyalgia.

INTRODUCTION: The importance of physical exercise for patients with fibromyalgia (FM) is very clear in the literature. Dancing is a type of aerobic exercise that has great acceptance. In addition to the beneficial effects of aerobic exercise, Zumba works on motor coordination and also has socializing as a part that should be included in patients with fibromyalgia. OBJECTIVES: To evaluate the effectiveness of Zumba dancing in improving pain, functional capacity, quality of sleep and quality of life of women with fibromyalgia. DESIGN: A pre-post treatment design. METHODS: We evaluated 19 women with fibromyalgia, selected by convenience. Data were collected in the second half of 2016. Zumba dancing was performed twice a week for 12 weeks. Patients were evaluated at week 0 (T0) and at week 12 (T12), by the following instruments: VAS (Visual Analogic Scale), Likert Scale, TUG (Timed Up an Go Test), 6MWT (Six-minute Walk Test), FIQ (Fibromyalgia Impact Questionnaire), PSQI (Pittsburgh Sleep Quality Index), ESS (Epworth Sleepiness Scale) and SF-36 quality of life. RESULTS: We found differences in pain (VAST0 = 6.21 and VAST12 = 4.53) with p = 0.001 and in the domain physical functioning of SF36 (T0 = 42.37 and T12 = 52.11) with p = 0.04. No differences were found for the other variables between the times. CONCLUSION: Zumba dancing as a form of treatment for three months for patients with fibromyalgia was effective in improving pain and physical functioning. Future controlled and randomized clinical trials should be performed to improve the evidence of Zumba dancing in women with fibromyalgia.

Torque, power and fatigue ratio in knee flexors and extensors of soccer players / índice de torque, potência e fadiga nos flexores e extensores do joelho de jogadores de futebol / índice de par de torsión, potencia y fatiga en los flexores y extensores de la rodilla de jugadores de fútbol

ABSTRACT Introduction: Soccer is the most popular and practiced sport in the world and is characterized by high intensity movements. This high demand induces several types of locomotor system injury, and one of the intrinsic factors responsible for triggering these injuries is muscle imbalances, which can occur between limbs or between muscles groups of the same limb. Objective: To evaluate the muscular performance between knee flexor/extensor groups of both limbs in professional soccer athletes.: Methods: Isokinetic assessments were performed in 18 professional soccer athletes, with mean age of 26.9 ± 3.6 years and mean body mass index (BMI) of 23.9 ± 1.7 kg/m2.. The test protocol consisted of five concentric contractions of knee flexion and extension at angular velocity of 60o/sec, 15 contractions at 180o/sec and 30 contractions at 300o/sec in both limbs. Test paired t-test was used to verify the torque, power, and fatigue ratio of flexors and extensors of the dominant and non-dominant knee. Results: There was no significant difference between the evaluated members related to dominance (p>0.05). Regarding the torque ratio between flexors and extensors, we observed values below what is considered normal for this population, besides a higher fatigue index in knee flexor group when compared with the extensor group. Conclusion: No better performance was observed in the dominant limb, suggesting that, although this limb is preferred, this does not necessarily characterizes the better performance. The data also revealed an imbalance in the torque production capacity between the knee flexor and extensor groups, with an unfavorable ratio for the hamstrings, as well as a higher fatigue index in this group, which would make these muscles more susceptible to injures.

RESUMO Introdução: O futebol é o esporte mais popular e mais praticado no mundo e caracteriza-se por movimentos de alta intensidade. Essa alta demanda induz diversos tipos de lesões do aparelho locomotor, e um dos fatores intrínsecos responsável por desencadear essas lesões é o desequilíbrio muscular, que pode ocorrer entre os membros ou entre grupos musculares de um mesmo membro. Objetivo: Avaliar o desempenho muscular entre os grupos flexores/extensores do joelho de ambos os membros em atletas profissionais de futebol. Métodos: Foram realizadas avaliações isocinéticas em 18 atletas profissionais de futebol, com média de idade de 26,9 ± 3,6 anos e índice de massa corporal (IMC) médio de 23,9 ± 1,7 kg/m2. O protocolo do teste consistiu em cinco contrações concêntricas de flexão e extensão do joelho na velocidade angular de 60º/s, 15 contrações a 180º/s e 30 contrações a 300º/s, em ambos os membros. O teste t pareado foi utilizado para verificar a razão do torque, potência e fadiga de flexores e extensores do joelho dominante e do não dominante. Resultados: Não houve diferença significativa entre os membros avaliados no que se refere à dominância (p>0,05). Com relação à razão de torque entre flexores e extensores, observaram-se valores abaixo do que se considera normal para essa população, além de um maior índice de fadiga no grupo flexor quando comparado com o grupo extensor do joelho. Conclusão: Não foi observado desempenho melhor no membro dominante, sugerindo que, embora haja preferência do uso desse membro, isso não caracteriza necessariamente a melhor performance. Os dados também revelaram um desequilíbrio na capacidade de produção de torque entre o grupo flexor e extensor do joelho, com razão desfavorável para os isquiotibiais, além de maior índice de fadiga nesse grupo, o que tornaria esses músculos mais suscetíveis a lesões.

RESUMEN Introducción: El fútbol es el deporte más popular y más practicado en el mundo y se caracteriza por movimientos de alta intensidad. Esta alta demanda induce diversos tipos de lesiones del aparato locomotor y uno de los factores intrínsecos responsables de desencadenar esas lesiones es el desequilibrio muscular, que puede ocurrir entre los miembros o entre grupos musculares de una misma extremidad. Objetivo: Evaluar el rendimiento muscular entre los grupos flexores y extensores de la rodilla de ambas extremidades en atletas profesionales de fútbol. Métodos: Se realizaron evaluaciones isocinéticas en 18 atletas profesionales de fútbol, con promedio de edad de 26,9 ± 3,6 años e índice de masa corporal (IMC) promedio de 23,9 ± 1,7 kg/m2. El protocolo del ensayo consistió en cinco contracciones concéntricas de flexión y extensión de la rodilla a la velocidad angular de 60º/s, 15 contracciones a 180º/s y 30 contracciones a 300º/s, en ambas extremidades. La prueba t pareada se utilizó para verificar la razón del par de torsión, potencia y fatiga de flexores y extensores de la rodilla dominante y no dominante. Resultados: No hubo diferencia significativa entre las extremidades evaluadas en lo que se refiere a la dominancia (p > 0,05). Con respecto a la razón de par entre flexores y extensores, se observaron valores por debajo de lo que se considera normal para esta población, además de un mayor índice de fatiga en el grupo flexor cuando se compara con el grupo extensor de la rodilla. Conclusión: No se observó un mejor desempeño en la extremidad dominante, sugiriendo que, aunque hay preferencia del uso de esa extremidad, esto no caracteriza necesariamente un mejor rendimiento. Los datos también revelaron un desequilibrio en la capacidad de producción de par de torsión entre el grupo flexor y extensor de la rodilla, con una razón desfavorable para los isquiotibiales, además de un mayor índice de fatiga en ese grupo, lo que haría que esos músculos fueran más susceptibles a las lesiones.
