Translation, Cross-Cultural Adaptation, and Measurement Properties of the Brazilian-Portuguese Version of the Fear of Falling Avoidance Behavior Questionnaire in Older Adults.

The aim of this study was to translate and culturally adapt the Fear of Falling Avoidance Behavior Questionnaire (FFABQ) into Brazilian-Portuguese (FFABQ-B), and to examine its reliability and validity in Brazilian older adults. The FFABQ-B was translated and tested in 10 Brazilian older adults. We assessed 52 community-dwellers, 68.7 (±6.2) years, using the FFABQ-B, BERG Balance Scale, Activities-specific Balance Confidence Scale, Falls Efficacy Scale, 6-Minute Walk Test, Timed Up and Go test, and activity monitor. Internal consistency, test-retest reliability, construct validity, and floor and ceiling effects were analyzed. The FFABQ-B had adequate internal consistency (Cronbach's α = .90) and test-retest reliability (intraclass correlation coefficient = .81; 95% confidence interval [.68, .90]). The FFABQ-B was associated with 6-Minute Walk Test, Timed Up and Go, BERG Balance Scale, physical activity time (p < .05), Activities-specific Balance Confidence scale, and Falls Efficacy Scale (p < .001). The FFABQ-B is both reliable and valid to assess avoidance behavior in activities and participation due to fear of falling in Brazilian community-dwelling older adults.

Correlation between clinical tests and electroneuromyography for the diagnosis of leprosy neuropathy.

BACKGROUND: In leprosy, sensory function of nerves is evaluated with monofilaments test and the motor function with voluntary muscle test, however electroneuromyography is considered as the gold-standard tool. OBJECTIVES: This study aimed: i) to evaluate the correlation between clinical tests and electroneuromyography for the diagnosis of leprosy neuropathy; and ii) to identify the prevalence of leprosy neuropathy and the most compromised peripheral nerves in leprosy. METHODS: We analysed the data from a nested case-control study that identified 166 patients diagnosed with leprosy neuropathy confirmed by electromyography. This study was designed for an analysis of correlation between the diagnostic tests. RESULTS: The most prevalent type of the neural damage was the sensory and motor multiple mononeuropathy, observed in 62 (37.3%) cases. The highest prevalence was the ulnar nerve in 67 (40.3%) cases. Agreement specified by nerves was moderate, ranging from k = 0.58 in the deep peroneal nerve to k = 0.41 in the posterior tibial nerve). Overall agreement between the clinical tests and electroneuromyography was very poor. Monofilaments test with k = 0.02 (95% CI 0.00-0.12) and voluntary muscle test with 0.16 (95% CI 0.04 to 0.28, P = 0.01). CONCLUSIONS: There is a low to moderate correlation between clinical tests (monofilaments and voluntary muscle tests) and the electroneuromyography examination. The most prevalent type of neural impairment was the sensory and motor multiple mononeuropathy, and the most affected nerve was the ulnar.

The Relationship of Knee-related Quality of Life With Function, Psychological Factors, Strength, Performance, and Postural Stability After ACL Reconstruction: A Cross-Sectional Study.

BACKGROUND: Patients after anterior cruciate ligament reconstruction (ACLR) have decreased health-related quality of life (QoL) compared with healthy control participants. Few studies have verified the predictors of QoL using Quality of Life Outcome Measure Questionnaire for Chronic Anterior Cruciate Ligament Deficiency (ACL-QoL), and no study has verified the relationship of psychological factors and knee function with ACL-QoL in patients after ACLR. HYPOTHESIS: Knee functional status, muscle strength, performance in hop tests, postural stability, and psychological factors would be the predictors of QoL after ACLR. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 4. METHODS: A total of 131 participants who had undergone ACLR at least 6 months previously were evaluated. QoL was assessed using ACL-QoL; knee functional status, using International Knee Documentation Committee Subjective Knee (IKDC) and global rating scale (GRS); psychological readiness, using Anterior Cruciate Ligament Return to Sport after Injury Scale (ACL-RSI); kinesiophobia, using Tampa Scale for Kinesiophobia (TSK-17); knee strength, using isokinetic dynamometer; performance, using single-leg hop tests; and postural stability, using Biodex Balance System. Pearson's linear correlation and stepwise hierarchical multiple linear regression analyses were performed to verify the predictors of QoL. RESULTS: ACL-QoL showed a moderate correlation with IKDC (r = 0.69), GRS (r = 0.55), ACL-RSI (r = 0.50), and TSK-17 (r = -0.49). ACL-QoL presented none to low correlations with the variables of muscle strength, postural stability, and performance in hop tests. The variables related to the knee functional status and psychological factors (IKDC, GRS, ACL-RSI, and TSK-17) were found to be the predictors of QoL (R2 = 0.56; P = 0.01). CONCLUSION: Knee functional status, psychological readiness, and kinesiophobia were the predictors of knee-related QoL in patients after ACLR. CLINICAL RELEVANCE: These results can assist clinicians in the therapeutic monitoring of the factors that may interfere with QoL in patients after ACLR.

The Brazilian version of the Victorian Institute of Sport Assessment - Hamstring (VISA-H) Questionnaire: Translation, cross-cultural adaptation and measurement properties.

STUDY DESIGN: Study of diagnostic accuracy/assessment scale. BACKGROUND: Proximal hamstring tendinopathy (PHT) usually causes disability, deep pain in the proximal insertion of the tendon, and limitations in daily life and sports practice. Scales that assess PHT pain and disability may assist practitioners in their clinical decision-making processes. OBJECTIVES: To perform a translation, cross-cultural adaptation and to evaluate the measurement properties of the Victorian Institute of Sport Assessment - Hamstring (VISA-H) questionnaire for the Brazilian population. METHODS: The VISA-H was adapted to Brazilian Portuguese (VISA-H-Br) and applied in 2 occasions with 5-8-day intervals. The following measurement properties were evaluated: internal consistency, test-retest reliability, standard error of the measurement (SEM), smallest detectable change (SDC), structural validity, and construct validity. Ninety (n = 90) participants (40 PHT and 50 asymptomatic participants) were evaluated using the Lower Extremity Functional Scale (LEFS) and VISA-H. PHT was diagnosed via clinical examination. RESULTS: The questionnaire was successfully translated, cross-culturally adapted, and renamed VISA-H-Br. The VISA-H-Br questionnaire demonstrated high internal consistency (Cronbach α = 0.96), excellent test-retest reliability (ICC = 0.90, CI 95% 0.83-0.93), and strong construct validity (rho = 0.692, p < 0.01 compared to LEFS). The SEM was 2.15 points, and the SDC was 5.96 points. No ceiling or floor effects were detected. CONCLUSION: The Brazilian version of the VISA-H was consistent, reliable, and valid. Therefore, it may be used in clinical practice and research to assess the pain and disability of patients with PHT.

Measurement properties of the Brazilian Portuguese anterior cruciate ligament - return to sport after injury (ACL-RSI) scale short version after anterior cruciate ligament reconstruction.

BACKGROUND: Higher scores (closer to 100) on the Anterior Cruciate Ligament - Return to Sport after Injury (ACL-RSI) scale indicate better psychological readiness to return to sport after anterior cruciate ligament reconstruction (ACLR). OBJECTIVES: To verify the validity and reliability of the ACL-RSI-short version (ACL-RSI-SV) in Brazilian Portuguese in individuals who underwent ACLR. METHODS: Participants (n=168) answered the Brazilian versions of ACL-RSI, Tampa Scale for Kinesiophobia (TSK-17), and International Knee Documentation Committee (IKDC) to assess the convergent validity of the short version. Internal consistency was also verified through correlation between items. Scores of participants who did not return to sport, who returned at a lower level, and at the pre-injury level were compared to verify divergent validity. ACL-RSI was answered again after 5-8 days to verify test-retest reliability. RESULTS: ACL-RSI-SV in Brazilian Portuguese showed good test-retest reliability (ICC2.1 = 0.85, 95% CI: 0.76, 0.90) and acceptable internal consistency (Cronbach's alpha = 0.78). Standard error of measurement (SEM) and smallest detectable change (SDC) were 4.98 and 13.82. High positive correlation was found with the full version of the ACL-RSI (r=0.93, 95% CI: 0.91, 0.95), moderate positive correlation with the IKDC (r=0.52, 95% CI: 0.40, 0.62), and weak negative correlation with the TSK-17 (r = -0.45, 95% CI: -0.60, -0.28). It also presented good divergent validity to identify individuals who returned to sport. CONCLUSION: ACL-RSI-SV in Brazilian Portuguese is a consistent, valid, and reliable instrument to assess patients who have undergone ACLR, with good ability to identify those who return to sport.

Clinimetric properties of the knee extension prone test (KEPT): A new method to assess knee hyperextension deficit.

INTRODUCTION: The knee extension prone test (KEPT) can be a low-cost and affordable alternative for this assess knee hyperextension deficit. OBJECTIVE: To analyze concurrent validity and reliability of a new method for assessing knee extension prone (knee extension prone test; KEPT). METHODS: Participants were divided into two groups: Group 1 comprised healthy participants (HG) and Group 2 comprised participants with a history of knee injury (IG). Two examiners performed the following evaluations: (1) lateral knee goniometry, (2) anterior tibial inclinometry, (3) lateral photogrammetry in supine, (4) lateral photogrammetry in prone, and (5) KEPT. Concurrent validity was analyzed by Pearson's linear correlation coefficient (r), and intra- and inter-examiner reliability were analyzed by intraclass correlation coefficient (ICC). RESULTS: KEPT demonstrated good intra-examiner (ICC = 0.85, 95% CI = 0.75-0.89) and excellent inter-examiner (ICC = 0.92, 95% CI = 0.88-0.94) reliability. The standard error of measurement was 0.47° and 1.30° and the minimum detectable change was 2.35° and 6.5° for intra- and inter-examiner agreement, respectively. Concurrent validity of KEPT ranged from moderate to good (r = 0.54-0.78, p < 0.01). CONCLUSION: KEPT is a valid and reliable method for assessing knee hyperextension deficit in both healthy individuals and patients with knee injuries.

Comparison of the Effect of Osteopathic Manipulations and Exercises on the Myoelectric Activity of the Pelvic Floor: A Randomized Controlled Trial.

Objective: The purpose of this clinical trial was to compare the effects of 4 different interventions on electromyographic activity of the pelvic floor muscles in women with stress urinary incontinence (UI). Methods: Fifty-one women with stress UI were randomized into 4 groups: a global osteopathic protocol (myofascial, visceral, and articular techniques); 1 manipulation technique (high-velocity, low-amplitude/thrust) of the sacroiliac joint and T10-L2; training of the pelvic floor muscles; and no intervention (control). Electromyographic activity of the pelvic floor muscles was evaluated at 5 different times (baseline, immediately after the procedure, 30 minutes, 1 hour, and 4 weeks after intervention). Results: Forty women completed the study. There were no immediate or late effects on the myoelectric activity of any type of muscle fiber in any of the groups analyzed. Conclusion: There were no significant between-groups differences of electromyography in women with symptoms of stress UI.

Reliability, validity and responsiveness of the Step Up and Down (StUD) test for individuals with symptomatic knee osteoarthritis.

BACKGROUND: Stair climbing test (SCT) has been suggested as the first task affected in individuals with symptomatic knee osteoarthritis (KOA). However, there are environmental barriers for the execution of the 9- to 12-step SCT. Thus, we developed a feasible one-step SCT that could be completed in 15s. OBJECTIVE: To check the clinimetric properties of the 15s Step Up and Down (StUD) test in individuals with KOA. DESIGN: Prospective validity study. METHOD: Eighty-two individuals with KOA participated in this study. The test-retest reliability of the StUD test was measured with a 1-week interval. The construct validity and responsiveness were assessed by testing predefined hypotheses. For this, the 30s Chair Stand Test (30CS), Timed Up and Go Test (TUG), quadriceps strength, Knee Injury and Osteoarthritis Outcome Score (KOOS), and Lequesne Algofunctional Index were used as comparator instruments. RESULTS: The StUD test presented good test-retest reliability (ICC = 0.87; 95% CI = 0.79-0.91) and showed a moderate to good correlation with the 30CS (r = 0.65), TUG (r = -0.56), and quadriceps strength (r = 0.41). We found a higher correlation between the StUD test and the performance-based tests than the patient-reported outcome measures. The StUD test was responsive, with five out of the six (83.3%) hypotheses confirmed. CONCLUSION: StUD test showed good reliability, adequate validity and responsiveness. Our findings suggest that StUD is a useful performance-based test for individuals with KOA.

Anteromedial versus posterolateral hip musculature strengthening with dose-controlled in women with patellofemoral pain: A randomized controlled trial.

OBJECTIVE: To compare the effectiveness of adding anteromedial versus posterolateral hip musculature strengthening to knee strengthening in women with patellofemoral pain (PFP). DESIGN: Randomized controlled trial. SETTING: University physiotherapy clinic. PARTICIPANTS: Fifty-two women with PFP were randomized to receive either anteromedial (AMHG) or posterolateral (PLHG) hip musculature strengthening. MAIN OUTCOME MEASURES: The primary outcomes were pain intensity by the numeric pain rating scale and function by the Anterior Knee Pain Scale in six weeks. Secondary outcomes were pain and function at six months, global perceived effect at six weeks and six months, pain in step down, isometric torque of abductors, adductors and hip rotators measured with hand-held dynamometer, and dynamic knee valgus by step down in six weeks. RESULTS: Both groups showed improvement in primary outcomes; however, no differences were found between groups in pain intensity and function in six weeks and the secondary outcomes. Group x time interaction found superior gains in abductor strength in the PLHG and increase in the strength of the adductors and internal rotators in AMHG. CONCLUSION: There was no difference between the addition of anteromedial or posterolateral hip musculature strengthening to knee strengthening in improving pain and function in women with PFP.

Immediate effects of diaphragmatic myofascial release on the physical and functional outcomes in sedentary women: A randomized placebo-controlled trial.

BACKGROUND: Although diaphragmatic myofascial release techniques are widely used in clinical practice, few studies have evaluated the simultaneous acute effects of these techniques on the respiratory and musculoskeletal systems. OBJECTIVE: To evaluate the immediate effects of diaphragmatic myofascial release in sedentary women on the posterior chain muscle flexibility; lumbar spine range of motion; respiratory muscle strength; and chest wall mobility. DESIGN: A randomized placebo-controlled trial with concealed allocation, intention-to-treat analysis, and blinding of assessors and participants. PARTICIPANTS: Seventy-five sedentary women aged between 18 and 35 years. INTERVENTION: The sample was randomly allocated into one of two groups; the experimental group received two diaphragmatic myofascial release techniques in a single session, and the control group received two placebo techniques following the same regimen. OUTCOMES MEASURES: The primary outcome was chest wall mobility, which was analyzed using cirtometry. The secondary outcomes were flexibility, lumbar spine range of motion, and respiratory muscle strength. Outcomes were measured before and immediately after treatment. RESULTS: The manual diaphragm release techniques significantly improved chest wall mobility immediately after intervention, with a between-group difference of 0.61 cm (95% CI, 0.12-1.1) for the axillary region, 0.49 cm (95% CI, 0.03-0.94) for the xiphoid region, and 1.44 (95% CI, 0.88-2.00) for the basal region. The techniques also significantly improved the posterior chain muscle flexibility, with a between-group difference of 5.80 cm (95% CI, 1.69-9.90). All movements except flexion of the lumbar spine significantly increased. The effects on respiratory muscle strength were non-significant. CONCLUSION: The diaphragmatic myofascial release techniques improve chest wall mobility, posterior chain muscle flexibility, and some movements of the lumbar spine in sedentary women. These techniques could be considered in the management of people with reduced chest wall and lumbar mobility. TRIAL REGISTRATION: NCT03065283.

Translation, cross-adaptation and measurement properties of the Brazilian version of the ACL-RSI Scale and ACL-QoL Questionnaire in patients with anterior cruciate ligament reconstruction.

BACKGROUND: Scales to assess the quality of life and return-to-sport after reconstruction of the anterior cruciate ligament (ACL) may help the clinical decision-making process. OBJECTIVE: To cross-culturally adapt and determine the validity of the Brazilian versions of the Anterior Cruciate Ligament Return to Sport after Injury (ACL-RSI) and the Quality of Life Questionnaire (ACL-QoL). METHODS: The process of translation and cross-cultural adaptation followed the recommendations of international guidelines. One hundred participants filled out the Brazilian versions of these instruments, the Tampa Scale for Kinesiophobia (TSK), the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, and the 36-Item Short Form Health Survey (SF-36). The measurement properties of reliability, internal consistency and construct validity were measured. RESULTS: The ACL-RSI and the ACL-QoL were successfully translated and cross-culturally adapted. Both questionnaires showed good test-retest reliability (ICC2,1=0.78, 95% CI=0.67-0.85 for the ACL-RSI; and ICC2,1=0.84, 95% CI=0.76-0.90 for the ACL-QoL) and good internal consistency (Cronbach's alpha=0.87 for the ACL-RSI; and Cronbach's alpha=0.96 for the ACL-QoL). A reasonable correlation was found between both questionnaires and the TSK, and a low to reasonable correlation was found between the questionnaires and the SF-36 in terms of validity. Compared to the IKDC Subjective Knee Evaluation Form, the ACL-RSI had a reasonable correlation and the ACL-QoL had a good correlation. CONCLUSION: The Brazilian versions of the ACL-RSI and the ACL-QoL have adequate measurement properties and may be used in assessing Brazilians after ACL reconstruction.

Physiotherapy Questionnaires App to Deliver Main Musculoskeletal Assessment Questionnaires: Development and Validation Study.

BACKGROUND: Patient-reported outcomes (PROs) translate subjective outcomes into objective data that can be quantified and analyzed. Nevertheless, the use of PROs in their traditional paper format is not practical for clinical practice due to limitations associated with the analysis and management of the data. To address the need for a viable way to group and utilize the main functioning assessment tools in the field of musculoskeletal disorders, the Physiotherapy Questionnaires app was developed. OBJECTIVE: This study aims to explain the development of the app, to validate it using two questionnaires, and to analyze whether participants prefer to use the app or the paper version of the questionnaires. METHODS: In the first stage, the app for an Android operational system was developed. In the second stage, the aim was to select questionnaires that were most often used in musculoskeletal clinical practice and research. The Foot and Ankle Outcome Score (FAOS) and American Orthopaedic Foot and Ankle Society (AOFAS) questionnaire were selected to validate the app. In total, 50 participants completed the paper and app versions of the AOFAS and 50 completed the FAOS. The study's outcomes were the correlation of the data between the paper and app versions as well as the preference of the participants between the two versions. RESULTS: The app was approved by experts after the adaptations of the layout for mobile phones and a total of 18 questionnaires were included in the app. Moreover, the app allows the generation of PDF and Excel files with the patients' data. In regards to validity, the mean of the total scores of the FAOS were 91.54% (SD 8.86%) for the paper version and 91.74% (SD 9.20%) for the app. There was no statistically significant differences in the means of the total scores or the subscales (P=.11-.94). The mean total scores for the AOFAS were 93.94 (SD 8.47) for the paper version and 93.96 (SD 8.48) for the app. No statistically significant differences were found for the total scores for the AOFAS or the subscales (P>.99). The app showed excellent agreement with the paper version of the FAOS, with an ICC value of 0.98 for the total score (95% CI 0.98-0.99), which was also found for the AOFAS with the ICC for the total score of 0.99 (95% CI 0.98-0.99). For compliance, 72% (36/50) of the participants in the FAOS group and 94% (47/50) in the AOFAS group preferred the app version. CONCLUSIONS: The Physiotherapy Questionnaires app showed validity and high levels of compliance for the FAOS and AOFAS, which indicates it is not inferior to the paper version of these two questionnaires and confirms its viability and feasibility for use in clinical practice.

Effect of unilateral bag use on plantar pressures and static balance in women / Efeito do uso da bolsa unilateral nas pressões plantares e no equilíbrio estático em mulheres

Abstract Introduction: The increasing insertion of women into the labor market has created a need to adapt handbags, with different sizes and weights, which consequently can overload the musculoskeletal system. Objective: To evaluate the effect of using a unilateral bag on plantar pressures and static balance in women. Methods: Cross-sectional study, carried out in Fortaleza in 2018. 258 women aged between 18 and 59 years who used a unilateral bag participated in this study. Two questionnaires were applied, targeting sociodemographic variables, life habits, characteristics of bag use and level of physical activity. Height, scapular symmetry, body and bag mass were also measured. A baropodometer was used to assess plantar pressure and static balance with and without the unilateral bag. Independent and paired t-tests were applied to verify the influence of the bag on the variables of interest, using the SPSS Statistics program (version 23.0). Results: On the side where the bag was carried, an increase in lateral mass distribution (LMD), foot pressure and surface area, and a decrease in the distance from barycenter (p < 0.05) were observed. On the opposite side, a decrease in LMD and an increase in barycenter were detected (p < 0.05). In static balance, no differences were observed in the anteroposterior and side-to-side oscillations with bag placement (p > 0.05). Conclusion: The unilateral bag causes alterations in plantar pressures and ipsilateral barycenter alongside the use of the bag, being a risk factor or aggravation for dysfunctions of the musculoskeletal system and for the occurrence of pain.

Resumo Introdução: A crescente inserção das mulheres no mercado de trabalho ocasionou uma necessidade de adaptação das bolsas, com tamanhos e pesos diferentes, que por consequência podem sobrecarregar o sistema musculoesquelético. Objetivo: Avaliar o efeito do uso da bolsa unilateral nas pressões plantares e no equilí-brio estático em mulheres. Métodos: Estudo transversal, realizado na cidade de Fortaleza em 2018. Participaram 258 mulheres com idade entre 18 e 59 anos e que usavam bolsa unilateral. Aplicaram-se dois questionários visando as variáveis sociodemográficas, hábitos de vida, características do uso da bolsa e nível de atividade física. Foram mensuradas estatura, simetria escapular, massa corporal e da bolsa. Utilizou-se baropodômetro para a avaliação das pressões plantares e equilíbrio estático com e sem a bolsa unilateral. Aplicaram-se testes t de amostras independentes e pareado para verificar a influência da bolsa nas variáveis de interesse, pelo programa SPSS Statistics (versão 23.0). Resultados: No lado que a bolsa era carregada foram observados aumento da distribuição de massa lateral (DML), da pressão do pé e da área de superfície e diminuição da distância do baricentro (p < 0,05). No lado oposto foram detectados diminuição da DML e aumento do baricentro (p < 0,05). No equilíbrio estático, não foram verificadas diferenças nas oscilações ântero-posterior e látero-lateral com a colocação da bolsa (p > 0,05). Conclusão: A bolsa unilateral causa alterações nas pressões plantares e no baricentro homolaterais no lado do uso da bolsa, sendo um fator de risco ou agravamento para as disfunções do sistema musculoesquelético e para a ocorrência de dor.

BIOMECHANICAL DIFFERENCES IN BRAZILIAN JIU-JITSU ATHLETES: THE ROLE OF COMBAT STYLE.

BACKGROUND: Brazilian Jiu-Jitsu (BJJ) athletes can be divided into two combat styles: pass fighters (PFs) and guard fighters (GFs). Flexibility of the posterior chain muscles is highly necessary in these athletes, especially in GFs. On the other hand, isometric strength of the trunk extensors is required in PFs. Handgrip strength is important in holding the kimono of the opponent, and symmetrical lower-limb strength is important for the prevention of injuries due to the overload caused by training. PURPOSE: The aim of this study was to compare the biomechanical profiles of BJJ athletes with different combat styles using the following outcome measures: flexibility, trunk extensor isometric endurance, postural balance, handgrip isometric endurance and lower-limb muscle strength. METHODS: A cross-sectional study was conducted using 19 GFs and 19 PFs. The sit-and-reach test was used to evaluate the flexibility of the posterior chain muscles. The Biodex Balance System® was used to evaluate balance. A handgrip dynamometer and a dorsal dynamometer were used to evaluate handgrip and trunk extensor endurance, respectively. Quadriceps and hamstring strength were evaluated with an isokinetic dynamometer at 60 °/s. RESULTS: No differences were observed between groups in terms of flexibility, balance, handgrip isometric endurance or quadriceps and hamstring strength; however, PFs (81.33) showed more isometric trunk extension endurance than GFs (68.85) (p = 0.02). Both groups had low values for hamstring/quadriceps ratio. CONCLUSION: No significant biomechanical differences were observed between PFs and GFs. LEVEL OF EVIDENCE: 2b.

Index of fatigue quadriceps in soccer athletes after anterior cruciate ligament reconstruction.

OBJECTIVE: The present study aimed to evaluate the muscle fatigue of the quadriceps muscle in high-performance soccer players undergoing (anterior cruciate ligament) ACL reconstruction. METHODS: We evaluated 17 high-performance soccer players from three professional soccer teams of a state in Brazil from August 2011 to July 2012. All subjects were evaluated between 5.5 and 7 months after ACL reconstruction with a Biodex® isokinetic dynamometer (System 4 Pro) with test protocol CON/CON at 60°/s and 300°/s with 5 and 15 repetitions, respectively. In the calculation of local muscle fatigue, the fatigue index was used, which is calculated by dividing the labor done in the first one-third of the repetitions by that done at the final one-third of the repetitions, and multiplying by 100 to express a unit in percentage (i.e., as a discrete quantitative variable). RESULTS: All subjects were male, with a mean age of 21.3 ± 4.4 years and mean BMI 23.4 ± 1.53 cm; left dominance was observed in 47% (n = 8) of athletes, and right dominance, in 53% (n = 9) of athletes; and the limb involved in the lesion was the dominant in 29% (n = 5) and the non-dominant in 71% (n = 12). Fatigue rates were 19.6% in the involved limb and 29.0% in the non-involved limb. CONCLUSION: The results allow us to conclude that there was no significant difference between the limbs involved and not in ACL injuries regarding local muscle fatigue. No association was observed between the dominant side and the limb involved in the ACL injury.

OBJETIVOS: O presente estudo propõe avaliar a fadiga muscular do músculo quadríceps em atletas de futebol de alto rendimento submetidos à ligamentoplastia do ligamento cruzado anterior (LCA). MÉTODOS: Foram avaliados 17 atletas de futebol com alto rendimento que pertenciam conjuntamente a três times de futebol profissional de um determinado estado brasileiro, de agosto de 2011 a julho de 2012. Todos foram avaliados entre 5,5 e 7 meses de pós-operatório de ligamentoplastia do LCA no dinamômetro isocinético da marca Biodex® (System 4 Pro) com protocolo de teste CON/CON nas velocidades de 60°/s e 300°/s com 5 e 15 repetições, respectivamente. No cálculo da fadiga muscular local, usamos o índice de fadiga que é calculado com a divisão do trabalho feito no terço inicial das repetições pelo terço final das repetições e a multiplicação por 100 para expressar uma unidade em porcentagem (i.e., variável quantitativa discreta). RESULTADOS: Todos eram do sexo masculino, com média de 21,3 ± 4,4 anos; IMC médio de 23,4 ± 1,53 cm; com dominância à esquerda em 47% (n = 8) dos atletas; e a direita em 53% (n = 9) dos atletas; o membro envolvido na lesão foi o dominante em 29% (n = 5) dos casos e o não dominante em 71% (n = 12). Os índices de fadiga foram de 19,6% no membro envolvido e de 29,0% nos membros não envolvidos. CONCLUSÃO: Os resultados nos permitem concluir que não há diferença significativa entre os membros envolvidos e não envolvidos na lesão de LCA no que diz respeito à fadiga muscular local. Também não foi observada associação entre ser destro ou canhoto com o membro envolvido na lesão de LCA.

Reproducibility of the pressure biofeedback unit in measuring transversus abdominis muscle activity in patients with chronic nonspecific low back pain.

The Pressure Biofeedback Unit (PBU) is often used by clinicians and researchers to indirectly evaluate transversus abdominis (TrA) muscle activity. The purpose of this study was to evaluate the inter and intra-examiner reproducibility of the PBU in measuring TrA muscle activity in fifty patients with chronic nonspecific low back pain. This study was performed using a test-retest design with a seven day interval. An Intraclass Correlation Coefficient (ICC(2,1)) of 0.74 (95% CI 0.54 to 0.85) and 0.76 (95% CI 0.58 to 0.86) was observed for the intra and inter-examiner reproducibility, respectively. The intra-examiner agreement (Limits of Agreement - LOA = 2.1 to -1.8 mmHg) and the inter-examiner agreement (LOA = 2.0 to -1.9 mmHg) were within the limits of agreement on 95% of occasions. The reproducibility of PBU in measuring TrA muscle activity in patients with chronic nonspecific low back pain ranged from satisfactory to excellent.

Index of fatigue quadriceps in soccer athletes after anterior cruciate ligament reconstruction / Índice de fadiga do músculo quadríceps femoral em atletas de futebol após reconstrução do ligamento cruzado anterior

ABSTRACT OBJECTIVE: The present study aimed to evaluate the muscle fatigue of the quadriceps muscle in high-performance soccer players undergoing (anterior cruciate ligament) ACL reconstruction. METHODS: We evaluated 17 high-performance soccer players from three professional soccer teams of a state in Brazil from August 2011 to July 2012. All subjects were evaluated between 5.5 and 7 months after ACL reconstruction with a Biodex(r) isokinetic dynamometer (System 4 Pro) with test protocol CON/CON at 60°/s and 300°/s with 5 and 15 repetitions, respectively. In the calculation of local muscle fatigue, the fatigue index was used, which is calculated by dividing the labor done in the first one-third of the repetitions by that done at the final one-third of the repetitions, and multiplying by 100 to express a unit in percentage (i.e., as a discrete quantitative variable).

Todos foram avaliados entre 5,5 e 7 meses de pós-operatório de ligamentoplastia do LCA no dinamômetro isocinético da marca Biodex(r) (System 4 Pro) com protocolo de teste CON/CON nas velocidades de 60°/s e 300°/s com 5 e 15 repetições, respectivamente. No cálculo da fadiga muscular local, usamos o índice de fadiga que é calculado com a divisão do trabalho feito no terço inicial das repetições pelo terço final das repetições e a multiplicação por 100 para expressar uma unidade em porcentagem (i.e., variável quantitativa discreta). RESULTADOS: Todos eram do sexo masculino, com média de 21,3 ± 4,4 anos; IMC médio de 23,4 ± 1,53 cm; com dominância à esquerda em 47% (n = 8) dos atletas; e a direita em 53% (n = 9) dos atletas; o membro envolvido na lesão foi o dominante em 29% (n = 5) dos casos e o não dominante em 71% (n = 12). Os índices de fadiga foram de 19,6% no membro envolvido e de 29,0% nos membros não envolvidos. CONCLUSÃO: Os resultados nos permitem concluir que não há diferença significativa entre os membros envolvidos e não envolvidos na lesão de LCA no que diz respeito à fadiga muscular local. Também não foi observada associação entre ser destro ou canhoto com o membro envolvido na lesão de LCA.

Perfil da Fisioterapia Esportiva nas Instituições de Ensino Superior do Brasil / Profile of Sports Physiotherapy in colleges and universities in Brazil / Perfil de la Fisioterapia Deportiva en las Instituciones de Enseñanza Superior del Brasil

O I Fórum Nacional dos Docentes da Fisioterapia Esportiva descreve diretrizes para normatização do ensino de graduação e pós-graduação referente à Fisioterapia Esportiva, as quais fundamentam orientações para Instituições do Ensino Superior (IES). O objetivo do estudo foi descrever o perfil da disciplina/do módulo de Fisioterapia Esportiva nas IES do Brasil. Foi realizado um estudo transversal entre os meses janeiro a outubro de 2011 e buscou-se no sistema de informação e-MEC a identificação das 439 instituições que ofertam o curso de graduação em Fisioterapia. Posteriormente, houve um levantamento de informações nos planos pedagógicos dessas IES, observando-se grade curricular do curso, especificamente a existência da disciplina/do módulo de Fisioterapia Esportiva, carga horária e estágio supervisionado. Em seguida, foi aplicado um questionário aos coordenadores de 33% das IES que ofertam a disciplina/o módulo de Fisioterapia Esportiva. A disciplina de Fisioterapia Esportiva é ofertada em 56% das IES brasileiras com graduação em Fisioterapia; destas, 97% oferecem em caráter obrigatório e em 62% o conteúdo é ofertado unido a outra disciplina. Com base na resposta aos questionários, 31% dos cursos apresentam carga horária total da disciplina entre 30 a 45 horas/aula, 50% oferecem estágio supervisionado e apenas 20% das instituições oferecem pós-graduação lato sensu na área. Foi investigada também a titulação dos professores ministrantes: 24% deles são especialistas, 31% são mestres, apenas 3% são doutores e 34% obtiveram o título de sócio-especialista da Sociedade Nacional de Fisioterapia Esportiva (SONAFE). Observa-se que a Fisioterapia Esportiva nas IES do Brasil ainda não está de acordo com as diretrizes que normatizam o ensino de graduação e pós-graduação na área...

The first Brazilian Forum of Professors in Sports Physiotherapy describes guidelines to standardize the education in undergraduate and graduate courses in relation to Sports Physiotherapy, justifying an orientation for Institutions of Higher Education (IHE). The aim of this study was to describe the profile of the Sports Physiotherapy in Brazilian IHE. A cross sectional study was conducted from January to October, 2011. In the research on the e-MEC information system, 439 institutions that offer undergraduate Physiotherapy courses were identified. Subsequently, it was collected information from pedagogical plans of these IHE, about core curriculum, specifically the existence or absence of the discipline of Sports Physiotherapy, workload and traineeship. A questionnaire was given to the coordinators of 33% of IHE that offer the discipline of Sports Physiotherapy. This discipline is offered in 56% of the Brazilian IHE with Physiotherapy course, obligatorily in 97% and, in 62%, the content is offered together with another discipline. Based in the response to the questionnaires, 31% of the courses have a total discipline workload within 30 to 45 hours/class, 50% of the courses offer traineeship, and only 20% of the IHE offer graduate courses in the area. It was also investigated the teachers' titration: 24% of them are specialists, 31% have a master degree, only 3% have a PhD degree, and 34% achieved the specialist degree of Sociedade Nacional de Fisioterapia Esportiva (SONAFE). It is observed that Sports Physiotherapy in the Brazilian IHE is not in accordance with the guidelines that regulate the teaching in undergraduate and graduate courses in the area...

Análise da efetividade da liberação das interfaces nas disfunções neuro-ortopédicas do membro superior / Analysis of effective in the release of crush neuro-orthopedics dysfunctions of the upper limb

Basear o tratamento de um paciente apenas em seus sintomas e esquecer a causística e fatores contribuintes da patologia é com certeza uma forma de menosprezar todos os conhecimentos disponíveis sobre o assunto. Nas disfunções neuro-ortopédicas dos membros superiores busca-se alternativas que possam agregar efetividade no tratamento. Objetivo: o objetivo da pesquisa foi esclarecer e avaliar a influência das interfaces mecanicas nas patologias neuro-ortopédicas do membro superior. Método: foi realizado um estudo intervencionista com uma avaliação inicial seguida de um protocolo de tecnicas manipulativas em 16 pacientes durante 10 atendimentos e uma avalição final. Compararam-se os valores iniciais e finais da escala visual análoga da dor, goniometria, teste de flexão em pé e texte neurodinâmico. Resultados: foi observada uma diminuição da média de dor para 2,44 ±2,39 cm (p<0,01); uma redução dos testes neurais positivos de 50% (p<0,03), nos testes de flexão em pé e goniomeria não foram encontrados resultados significantes. Conclusão: conclui-se que a liberação das interfaces mecanicas obteve resultados efetivos para as disfunções neuro-ortopédicas do membro superior, no que diz respeito à diminuição do quadro álgico e sintomas neurais. Porém, não teve influência sobre a goniometria e teste de flexão em pé.

Basing the treatment of a patient only on his symptoms and forget about the series and contributing factors of the dissease is certainly a way to disparage all available knowledge on the subject. Neuro-orthopedc disorders of the upper limb seeks to alternatives that may add to treatment effectiveness. Objective: of this study was to clarify the influence of interfaces in neuro-orthopedic pathologies of the upper limb. Methods: wi comucted an interventionist study with an initial assessment fallowed by a protocol of manipulative techniques in 16 patients for 10 visits and a final assessment . We compare the initial and final values of the visual analog scale of pain, goniometry, flexion test stand and neurodymanic test. Results: we observed a decrease in average pain to 2.44±2.39 cm (p <0.01), a reduction of positive neural test 50% (p < 0.03), bending tests on foot and goniometry no results were found significant. Conclusion: we have concluded that the release of mechanical interfaces obtained effective results for neuro-orthopedic disorders of the upper lim, with regard to the reduction of pain and neural symptoms. However, there was no influence on goniometry and standing flexion test.
