RESUMO

Abstract Objective: To evaluate and compare the sexual function and pelvic floor muscles (PFM) function of women with endometriosis and chronic pelvic pain (CPP) with and without Myofascial Pelvic Pain Syndrome (MPPS). Methods: Cross-sectional study conducted between January 2018 and December 2020. Women with deep endometriosis underwent assessments for trigger points (TP) and PFM function using the PERFECT scale. Electromyographic activity (EMG) and sexual function through Female Sexual Function Index (FSFI) were assessed. Statistical analyses included chi-square and Mann-Whitney tests. Results: There were 46 women. 47% had increased muscle tone and 67% related TP in levator ani muscle (LAM). Weakness in PFM, with P≤2 was noted in 82% and P≥3 in only 17%. Incomplete relaxation of PFM presented in 30%. EMG results were resting 6.0, maximal voluntary isometric contraction (MVIC) 61.9 and Endurance 14.2; FSFI mean total score 24.7. We observed an association between increased muscle tone (P<.001), difficulty in relaxation (P=.019), and lower Endurance on EMG (P=.04) in women with TP in LAM. Participants with TP presented lower total FSFI score (P=.02). TP in the right OIM presented increased muscle tone (P=.01). TP in the left OIM presented lower values to function of PFM by PERFECT (P=.005), and in MVIC (P=.03) on EMG. Conclusion: Trigger points (TP) in pelvic floor muscles (PFM) and obturator internus muscle (OIM) correlates with poorer PFM and sexual function, particularly in left OIM TP cases. Endometriosis and chronic pelvic pain raise muscle tone, weaken muscles, hinder relaxation, elevate resting electrical activity, lower maximum voluntary isometric contraction, and reduce PFM endurance.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
