Risk Factors for Symptomatic Cyclops Lesion Formation after Anterior Cruciate Ligament Reconstruction / Fatores de risco para formação de lesão cyclops sintomática após a reconstrução do ligamento cruzado anterior

Abstract Objective To evaluate the incidence of symptomatic cyclops lesions requiring surgical treatment after anterior cruciate ligament (ACL) reconstruction and to establish possible intraoperative risk factors related to it. Methods Three hundred and eighty-nine patients aged between 18 and 50 years who underwent primary ACL reconstruction were retrospectively evaluated. Patients were divided into groups according to the presence or absence of symptomatic cyclops lesions, and their characteristics were compared. Patients with associated lesions that required additional surgical procedures (except anterolateral extra-articular procedures) were not included. The rate of symptomatic cyclops lesions was recorded and the following parameters were evaluated: age, gender, time from injury to surgery, graft type and diameter, femoral tunnel perforation technique, fixation type, presence of knee hyperextension, preservation of the ACL remnant, associated anterolateral extra-articular procedure, associated meniscal injury and participation in sports. Results 389 patients were evaluated and 26 (6.7%) patients developed cyclops. The patients with and without cyclops lesions did not differ in age, time from injury to surgery, graft type or diameter, surgical technique, femoral fixation method, presence of knee hyperextension, remnant preservation and associated meniscal injury. The group with cyclops lesion had a higher proportion of females (10 (38.4%) vs 68 (18.7%); OR = 2.7; p= 0.015), higher proportion of extra-articular reconstruction (18 (11.8%) vs 8 (3.4%); OR = 3.8; p= 0.001) and higher proportion of sports practice (23 (8.6%) vs 3 (2.5%); OR = 3.6; p= 0.026). Conclusion In our series, 6.7% of the patients required arthroscopic removal of cyclops lesions. Female gender, associated extra-articular reconstruction and sports practice were factors related to this lesion. Remnant preservation had no relationship with cyclops lesion formation.

Resumo Objetivo Avaliar a incidência de lesões cyclops sintomáticas que precisam de tratamento cirúrgico após a reconstrução do ligamento cruzado anterior (LCA) e estabelecer os possíveis fatores de risco intraoperatórios relacionados a elas. Métodos Trezentos e oitenta e nove pacientes com idades entre 18 e 50 anos submetidos à reconstrução primária do LCA foram avaliados de forma retrospectiva. Os pacientes foram divididos em grupos de acordo com a presença ou ausência de lesões cyclops sintomáticas e suas características foram comparadas. Não foram incluídos pacientes com lesões associadas que necessitassem de outros procedimentos cirúrgicos (à exceção de procedimentos extra-articulares ântero-laterais). A taxa de lesões cyclops sintomáticas foi registrada e os seguintes parâmetros foram avaliados: idade, sexo, tempo da lesão à cirurgia, tipo e diâmetro do enxerto, técnica de perfuração do túnel femoral, tipo de fixação, presença de hiperextensão do joelho, preservação do LCA remanescente, associação a procedimento extra-articular ântero-lateral, lesão de menisco associada e participação em esportes. Resultados Dos 389 pacientes avaliados, 26 (6,7%) desenvolveram lesão cyclops. Os pacientes com e sem lesão cyclops não diferiram quanto à idade, tempo da lesão à cirurgia, tipo ou diâmetro do enxerto, técnica cirúrgica, método de fixação femoral, presença de hiperextensão do joelho, preservação do LCA remanescente e lesão de menisco associada. O grupo com lesão cyclops apresentou mais mulheres (10 [38,4%] vs. 68 [18,7%]; razão de probabilidades [OR] = 2,7; p= 0,015), maior proporção de reconstrução extra-articular (18 [11,8%] vs. 8 [3,4 %]; OR = 3,8; p= 0,001) e maior proporção de prática esportiva (23 [8,6%] vs. 3 [2,5%]; OR = 3,6; p= 0,026). Conclusão Em nossa série, 6,7% dos pacientes necessitaram de remoção artroscópica das lesões cyclops. O sexo feminino, a reconstrução extra-articular associada e a prática esportiva foram fatores relacionados a essa lesão. A preservação do menisco remanescente não foi associada à formação de lesões cyclops.

Contexto e objetivo: Diversos benefícios são advindos da prática da atividade física durante o envelhecimento, porém poucos são os achados que apresentem os dados ao longo do tempo. Assim, o objetivo deste estudo foi verificar a estabilidade das variáveis da aptidão física e capacidade funcional de mulheres adultas praticantes de atividade física em um período de 10 anos. Desenho e local: Estudo longitudinal com mulheres de São Caetano do Sul. Métodos: A amostra foi composta por 157 mulheres com idade entre 45 e 86 anos (65,7 ± 6,7), analisadas em quatro intervalos de tempo: baseline, 6, 8 e 10 anos, todas praticantes de atividade física. A avaliação incluiu variáveis antropométricas, neuromotoras e de capacidade funcional. A análise estatística utilizada foi o teste t de Student, correlação de Spearman Rho e delta percentual. O nível de significância adotado foi de P < 0,01. Resultados: Os resultados apresentaram correlações de estabilidade alta e significante (rho = 0,64 a 0,87) nos três grupos nas variáveis índice de massa corporal, adiposidade, força de membros superiores, flexibilidade e agilidade. O acompanhamento de 6 a 10 anos evidenciou diferenças significantes de força de membros superiores, inferiores, agilidade e equilíbrio, sendo expressa pela redução da força de membros superiores de 8% a 13%, força de membros inferiores de 18% a 21%, agilidade de 18% a 19% e equilíbrio de 28% a 34%. Conclusão: Houve estabilidade das variáveis antropométricas, neuromotoras, capacidade funcional e equilíbrio de mulheres adultas praticantes de atividade física, mesmo apresentando redução significativa nas variáveis citadas anteriormente.

Morbimortalidad en pacientes con fracturas intertrocantéricas de cadera tratadas con clavos cefalomedulares. Valor predictivo del Índice de Movilidad de Parker / Morbidity and mortality in intertrochanteric hip fractures treated with cephalo-medullary nailing. Predictive value of the Parker mobility score

Introducción: La fractura de cadera es un factor independiente que aumenta la morbimortalidad. El objetivo de este estudio retrospectivo fue determinar la morbimortalidad en ancianos con fracturas intertrocantéricas de cadera tratadas con clavos cefalomedulares. Materiales y métodos: Se analizó a pacientes tratados con clavo cefalomedular por fractura intertrocantérica de cadera, entre 2018 y 2021, y un seguimiento mínimo de 12 meses. Se registraron: datos demográficos, comorbilidades, capacidad funcional con el Índice de Movilidad de Parker, complicaciones y tasa de mortalidad a los 12 meses y al final del seguimiento. Se identificaron las variables independientes relacionadas con complicaciones o muerte. Resultados: Se incluyó a 68 pacientes (seguimiento medio 23 meses). La tasa de complicaciones fue del 8,8%: infección urinaria, neumonía, trombosis venosa profunda y tres pérdidas de fijación del tornillo cefálico. Al comparar pacientes con complicaciones o sin ellas, hubo diferencias significativas en la edad cuando se produjo la fractura. Las tasas de mortalidad anual y al concluir el estudio fueron del 2,9% y 29,4%, respectivamente. Las diferencias fueron significativas en la incidencia de comorbilidades renales, demencia, el Índice de Comorbilidad de Charlson >4 y el puntaje de Parker <5 en quienes fallecieron. El puntaje de Parker <5 fue la variable independiente relacionada con muerte. Conclusiones: Las tasas de complicaciones y de mortalidad a los 12 meses del tratamiento de las fracturas intertrocantéricas inestables de cadera con clavos cefalomedulares es aceptable en ancianos. El riesgo de muerte aumenta significativamente si el puntaje de Parker es <5 antes de la fractura. Nivel de Evidencia: IV

Introduction: Hip fracture represents an independent predictor of morbidity and mortality. The aim of this retrospective study was to assess the morbidity and mortality associated with intertrochanteric hip fractures fixed with cephalomedullary nails. materials and methods: We analyzed all patients treated between 2018 and 2021 with a cephalomedullary nail for an intertrochanteric hip fracture, with a minimum follow-up of 12 months. We evaluated the demographic data, comorbidities, functional level through the Parker Mobility Score (PMS), complications, and mortality (12 months and at the end of follow-up). Variables related to postoperative complications or death were identified by bivariate and multivariate regression analyses. Results: 68 patients were included. The mean follow-up was 23 (range 12-40) months. The rate of complications was 8.8% (n=6), 1 urinary tract infection, 1 pneumonia, 1 deep vein thrombosis, and 3 (4.4%) cephalic screw fixation losses. Patients who had complications presented significant differences in age at the time of fracture. Mortality at 12 months and at the end of the study was 2.9% (n=2) and 29.4% (n=20) respectively. Those patients who died presented significant differences in the incidence of kidney comorbidities, dementia, a Charlson Comorbidity Index > 4, and a PMS < 5. PMS < 5 was the only independent variable related to mortality. Conclusions: Cephalomedullary nailing in unstable intertrochanteric hip fractures in elderly patients represents a treatment option that offers an acceptable complication rate and a low 12-month mortality rate. The risk of death is significantly increased in patients with low functional scores (Parker < 5) pre-fracture. Level of Evidence: IV

Effect of low-level LASER therapy versus CAD/CAM Michigan splint on patients with Temporomandibular Muscle Disorders: a randomized clinical trial / Efeito da terapia LASER de baixa potência versus placa de Michigan CAD/CAM em pacientes com Distúrbios Temporomandibulares musculares: um ensaio clínico randomizado

Objective: This study aimed to evaluate the efficacy and sustainability of using low level LASER therapy and CAD/CAM Michigan splint on improving the range of mandibular movements, muscle activity and reducing the pain. Material and Methods: 56 female patients were randomly divided into two groups. Group A: Patients received applications of low-level LASER therapy using semiconductor InGaAsp diode LASER type 940 nm with continuous mode of operation, applied for 180 sec per session for 12 sessions. Group B: Patients received Michigan splint of 2 mm thickness constructed on their upper teeth, the splint was 3D digitally printed. Electromyography was used to evaluate muscle activity, visual analogue scale was used to evaluate the pain intensity, ARCUS digma facebow was used to evaluate range of mandibular movements, and maximum mouth opening was taken using a millimeter ruler. They were measured before the beginning of the treatment, and at three and six month follow-up periods. Results: The results revealed that both low-level LASER therapy and Michigan splint reduce the myofascial pain, improved the range of the mandibular movements, and the muscles activity, but the effect of the low-level LASER therapy was more profound and sustainable. After 6 months from the beginning of the treatment, changes in masseter muscle activity (P= 0.001; effect size= 1.757), pain intensity (P= 0.003; effect size= 3), and range of mandibular movement (P= 0.001, effect size= 1.729) differed significantly between the two groups. Conclusions: Low-level LASER therapy had a better and more sustainable effect on reducing the pain intensity and improving the muscle activity as well as the mandibular movement when compared to Michigan splint (AU)

Objetivo: Este estudo teve como objetivo avaliar a eficácia e a durabilidade do uso da terapia LASER de baixa potência e da placa de Michigan CAD/CAM na melhora da amplitude dos movimentos mandibulares, atividade muscular e redução da dor. Material e Métodos: 56 pacientes do sexo feminino foram divididos aleatoriamente em dois grupos. Grupo A: os pacientes receberam aplicações de terapia LASER de baixa potência utilizando diodo semicondutor InGaAsp LASER tipo 940 nm em modo contínuo de operação, aplicado por 180 segundos por sessão durante 12 sessões. Grupo B: os pacientes receberam a placa de Michigan com uma espessura de 2 mm confeccionada sobre a arcada superior, a placa foi impressa digitalmente em 3D. A eletromiografia foi utilizada para avaliar a atividade muscular, a escala visual analógica foi utilizada para avaliar a intensidade da dor, o arco facial ARCUS digma foi utilizado para determinar a amplitude dos movimentos mandibulares e a abertura máxima da boca foi medida com uma régua milimétrica. Todas as medidas foram realizadas antes do início do tratamento e nos períodos de acompanhamento de três e seis meses. Resultados: Os resultados revelaram que tanto a terapia LASER de baixa potência como a placa de Michigan reduziram a dor miofascial, aumentaram a amplitude dos movimentos mandibulares e melhoraram a atividade muscular, mas o efeito da terapia LASER de baixa potência foi mais profundo e duradouro. Após 6 meses do início do tratamento, as alterações na atividade do músculo masseter (P= 0. 001; tamanho do efeito= 1,757), intensidade da dor (P= 0,003; tamanho do efeito= 3), e amplitude de movimento mandibular (P= 0,001, tamanho do efeito= 1,729) diferiram significativamente entre os dois grupos. Conclusão: A terapia com LASER de baixa potência teve um efeito melhor e mais duradouro na redução da intensidade da dor e na melhora da atividade muscular, bem como do movimento mandibular, quando comparada à placa de Michigan(AU)

Se registraron las complicaciones y las revisiones.Resultados: el seguimiento promedio fue de 42.6 meses (rango 24 a 92 meses). El score de Rowe, la EVA y el ASOSS mejoraron significativamente luego de la cirugía (p <0.1). Nueve pacientes retornaron al deporte, ocho de ellos al mismo nivel. El injerto óseo consolidó en todos los pacientes. No hubo recurrencias. No se reportaron complicaciones.Conclusión: el injerto autólogo de cresta ilíaca es una opción válida para el tratamiento de deportistas con inestabilidad glenohumeral recurrente luego de una estabilización previa fallida con cirugía de Latarjet. Nivel de Evidencia: IV

Introduction: The purpose of this study was to report the functional results, return to sport, consolidation rate and complications in young athletes with a previous failed Latarjet surgery, treated with an autologous iliac crest graft.Materials and methods: between 2017 and 2020, twelve patients with recurrent glenohumeral instability were operated on at our institution after previous failed stabilization with Latarjet surgery with autologous iliac crest graft as revision surgery. Functional evaluation was performed with the Rowe score, the VAS, and the ASOSS score. We evaluated the percentage of return to sport, the level reached, and the time it took the athletes to compete again. Bone consolidation and the adequate position of the graft were evaluated in all cases with front and profile X-rays of the shoulder and computed tomography with 3D reconstruction. Complications and revisions were recorded.Results: the average follow-up was 42.6 months (range 24 to 92 months). The Rowe score, visual analog scale, and ASOSS were significantly improved after surgery (p <0.1). Nine patients returned to sport, eight of them at the same level. The bone graft consolidated in all patients. There were no recurrences. No complications were reported.Conclusion: autologous iliac crest grafting is a valid option for the treatment of athletes with recurrent glenohumeral instability after previous failed stabilization with a Latarjet procedure.

Osteotomía selectiva como tratamiento de la inestabilidad medial de rodilla / Selective osteotomy as a treatment for medial knee instability

Las fracturas de platillos tibiales son lesiones frecuentes. Una de sus complicaciones postoperatorias es la pérdida de reducción con desviación de los ejes en los planos coronal, sagital y axial. La depresión ósea genera incongruencia articular con pérdida de tensión de estructuras ligamentarias indemnes, causando una pseudo-laxitud con inestabilidad. Esto requiere de una corrección ósea para aumentar la tensión de dichas estructuras ligamentarias y lograr así recuperar la congruencia y estabilidad articular en todo el rango de movilidad. El objetivo del presente trabajo es reportar un caso de inestabilidad medial en un paciente joven, quien, tras una fractura de platillo tibial medial mal consolidada, requirió una osteotomía selectiva biplanar e intraarticular para corregir dicha deformidad

Tibial plateau fractures are frequent. Loss of reduction with axis deviation in the coronal, sagittal and axial planes is one of the postoperative complications.Bone depression generates joint incongruity with loss of tension in undamaged ligament structures resulting in pseudo-laxity with instability. This requires a bone correction to increase the tension of ligament structures, hence achieving the recovery of joint congruence and stability throughout the range of mobility.The objective of the current paper is to report a case of medial instability in a young patient, who suffered a medial tibial plateau fracture with poor bone consolidation, with consequent laxity and pain in the medial compartment, which required a selective biplanar and intra-articular osteotomy to correct such deformity.

Corticoesteroide oral vs. intrarticular en el tratamiento de la capsulitis adhesiva / Oral versus intra-articular corticosteroid in the treatment of adhesive capsulitis

Introducción: La capsulitis adhesiva es una enfermedad que se caracteriza por el engrosamiento de la cápsula articular del hombro, lo que se traduce clínicamente en dolor y una pérdida progresiva de la movilidad. El tratamiento conservador es la primera opción. En este estudio, se evaluó el uso de corticoesteroides articulares para el manejo de este cuadro. Materiales y Métodos: Se llevó a cabo un estudio retrospectivo entre 2015 y 2020. Se evaluaron los registros de consulta externa de pacientes con diagnóstico de capsulitis adhesiva u hombro congelado, que recibieron tratamiento con corticoesteroides por vía oral o articular. Resultados: Se analizó a 19 pacientes, 8 recibieron tratamiento por vía oral y 11, por vía articular. Hubo una mejoría importante en ambos grupos, pero los pacientes que recibieron corticoesteroides articulares comunicaron una mejoría a largo plazo. Conclusiones: La administración de corticoesteroides tanto por vía oral como articular para tratar la capsulitis adhesiva fue eficaz; sin embargo, a largo plazo, los corticoesteroides articulares resultaron más eficaces. Nivel de Evidencia: III

Introduction: Adhesive capsulitis is a condition defined by thickening of the shoulder joint capsule, which clinically translates into discomfort and progressive loss of range of motion, with conservative therapy being the initial option. In this study, we evaluate the use of intra-articular corticosteroid injections for the treatment of this condition. Materials and Methods: A retrospective analysis was conducted between 2015 and 2020, assessing the outpatient records of patients diagnosed with adhesive capsulitis or frozen shoulder and treated with corticosteroids either orally or intra-articularly. Results: A total of 19 patients were analyzed, 8 received oral treatment and 11 received intra-articular injection, with both groups showing considerable improvement, with the difference that the patients in the articular corticosteroid group reported long-term improvement. Conclusion: Corticosteroids have been found to be effective in the treatment of adhesive capsulitis both orally and by intra-articular injection; however, intra-articular corticosteroids have proved to be more effective in the long term.

Patients Who Present with Functional Limitations, Limited Range of Motion and Reduced Muscle Strength 6 Months after Total Hip Arthroplasty: A Cross-Sectional Study / Pacientes que apresentam limitações funcionais, amplitude de movimento limitada e força muscular reduzida, 6 meses após a artroplastia total do quadril: Um estudo de corte transversal

Abstract Objective To evaluate levels of pain, range of motion, hip isometric peak torque, and functional task performance in patients 6 months after total hip arthroplasty (THA) and to compare them to asymptomatic control participants (CG). Methods We recruited participants with unilateral THA due to hip osteoarthritis (OA) within a median of 6 months who had not developed postoperative complications. We assessed the pain levels, hip range of motion, peak isometric torque, self-reported assessment (Harris Hip Score) and objectively measured function (Timed Up & Go Test [TUG]) of the patients. The THA group was compared with a group of asymptomatic participants ≥50 years old recruited in the community. Comparisons are presented as mean differences (MDs) and 95% confidence intervals (CIs). Results A total of 23 participants were included in each group. Pain levels were low in the THA group (1.48 [1.60]), and 91.3% of the patients reported to be satisfied with the surgical procedure. Participants in the THA group reported significantly lower objectively measured (THA 12.2 [10.0-21.6]; CG 9.0 [6.7-12.2]) and self-reported function (THA 78.5 [43.8-93.9]; CG 100.0 [95.8-100.0]) compared with CG. The THA group also had significantly reduced range of motion for flexion (p< 0.001), internal (p< 0.001) and external rotation (p= 0.003) movements and reduced peak torque for flexion (p< 0.001), extension (p< 0.001), abduction (p< 0.001) and adduction (p= 0.024) movements compared with participants of the CG. Conclusions Despite reporting overall low pain scores and satisfaction with the surgery, the patients present with functional limitations, limited range of motion, and reduced muscle strength 6 months after THA.

Resumo Objetivo Avaliar os níveis de intensidade da dor, amplitude de movimento, pico de torque isométrico do quadril e desempenho da tarefa funcional em pacientes 6 meses após a artroplastia total do quadril (ATQ), e comparar estes valores com os de participantes assintomáticos do grupo controle (GC). Métodos Recrutamos participantes com ATQ unilateral devida a osteoartrite (OA) do quadril, dentro de uma mediana de tempo de 6 meses, que não tinham desenvolvido complicações pós-operatórias. Os participantes foram avaliados quanto à intensidade da dor, à amplitude de movimento do quadril, ao pico de torque isométrico, à autoavaliação (questionário de avaliação do quadril Harris Hip Score [HHS, na sigla em inglês) e à função medida objetivamente por meio do teste Timed Up and Go (TUG, na sigla em inglês). O grupo ATQ foi comparado com um grupo de participantes assintomáticos com idade ≥ 50 anos recrutados na comunidade. As comparações são apresentadas como diferenças médias (DMs) e intervalos de confiança (ICs) de 95%. Resultados Cada grupo contou com 23 participantes. A intensidade da dor foi baixa no grupo ATQ (1,48 [1,60]), sendo que 91,3% dos pacientes relataram estar satisfeitos com o procedimento cirúrgico. Os participantes do grupo ATQ relataram uma função medida objetivamente significativamente menor (ATQ 12,2 [10,0-21,6]; GC 9,0 [6,7-12,2]) e a função autoavaliação (ATQ 78,5 [43,8-93,9]; GC 100,0 [95,8-100,0]), em comparação com o GC. O grupo ATQ também teve reduzida de forma significativa a amplitude de movimento para flexão (p< 0,001), os movimentos internos (p< 0,001) e de rotação externa (p= 0,003). O grupo ATQ também apresentou pico de torque reduzido para flexão (p< 0,001), extensão (p <0,001), movimentos de abdução (p< 0,001) e adução (p = 0,024) em comparação com os participantes do GC. Conclusões Apesar de informarem escores gerais de dor de baixa intensidade e satisfação com a cirurgia, os pacientes apresentaram limitações funcionais, amplitude de movimento limitada e redução da força muscular após 6 meses do procedimento cirúrgico de ATQ.

Modificación de la actividad metabólica por medio de un dispositivo intraoral en pacientes con hiperplasia condilar confirmada por SPECT / Metabolic activity modification by means of an intraoral device in patients with condylar hyperplasia confirmed by SPECT

Objetivo: Evaluar los efectos de la aplicación de un dispositivo intraoral de uso permanente en el comportamien- to de los cóndilos con hiperplasia condilar (HC) confirmada por tomografía computarizada de emisión por fotón único (SPECT), estableciendo una comparación con un grupo de pacientes con HC que no utilizó el dispositivo. Materiales y métodos: 30 pacientes con una edad promedio de 21,7 años (+/-5,56) con HC confirmada con SPECT fueron asignados al azar a dos grupos: a los del grupo I (n=18) se les colocó un dispositivo intraoral de uso perma- nente para modificar la posición de la mandíbula, mientras que a los del grupo II (n=12) no se les colocó ningún dispo- sitivo. Se realizaron evaluaciones de dolor, del desvío de la línea media, de la apertura máxima y del disconfort al inicio del estudio y a los 2, 4, 6, 10, 12 y 14 meses. A los 19 meses promedio, la actividad osteoblástica (AO) fue reevaluada me- diante SPECT. Resultados: En el grupo I, la AO en los cortes coro- nales y transversales cesó o disminuyó (p<0,001) respecto a la condición inicial, mientras que en el grupo II la AO au- mentó (p<0,001). Los datos fueron analizados utilizando el test de Wilcoxon de rangos signados. Al ajustar un modelo de ANCOVA robusto utilizando el valor inicial como covariable también se observa que el efecto del grupo fue estadística- mente significativo en ambos cortes (p<0,001). Conclusiones: La aplicación de un dispositivo intrao- ral de uso permanente mejora la evolución de la hiperplasia condilar, lo que lo puede convertir en un tratamiento de uti- lidad para el tiempo que se aguarda para realizar una condi- lectomía alta de cuello de cóndilo, o incluso para evitar este procedimiento (AU)

Objective: To evaluate the effects of the application of an intraoral device for permanent use on the behavior of con- dyles with condylar hyperplasia (CH) confirmed by single photon emission computed tomography (SPECT), establish- ing a comparison with a group of patients with CH that did not use the device. Materials and methods: Thirty patients with an aver- age age of 21.7 years (+/-5.56) with CH confirmed by SPECT were randomly divided into two groups: the ones in group I (n=18) received an intraoral device for permanent use to align the mandible, while those in group II (n=12) did not get any device. Pain, midline shift, maximum opening, and discomfort were evaluated at the beginning of the study and at 2, 4, 6, 10, 12, and 14 months. At an average of 19 months, osteoblastic activity (AO) was reassessed by SPECT. Results: In group I, the AO in the coronal and trans- verse sections ceased or decreased (p<0.001) in comparison to the initial condition, while in group II the AO increased (p<0.001). The data was analyzed by the Wilcoxon signed rank test. Adjusting a robust ANCOVA model using the ini-tial value as a covariate made it possible to observe that the effect of the group was statistically significant in both cuts (p<0.001). Conclusions: The application of an intraoral device for permanent use improves the evolution of condylar hyperpla- sia, which can make it a useful treatment until a high condylectomy of the neck of the condyle is performed, or even to avoid this procedure (AU)

Gender-based Variations in Trunk Motion and Isometric Strength in Young Adults with Low Back Pain: A Prospective Case-control Study / Variações baseadas em gênero no movimento e na força isométrica do tronco em jovens adultos com dor lombar: Um estudo de caso-controle prospectivo

Abstract Objective To determine gender-based variations in trunk range of motion (RoM) and isometric strength (IS) in symptomatic and asymptomatic young adults. Methods In this prospective case-control study, 73 subjects with low back pain (LBP) and 80 asymptomatic subjects were analyzed. Dynamometer-based device trunk RoM and IS measurements in extension, flexion, and rotation were compared in both groups and gender-based subgroups. Multivariate analysis was used to determine factors influencing trunk RoM and IS. Results Symptomatic males had significantly less extension RoM and extension, flexion, and rotation isometric trunk strength (ITS) (p < 0.0001) compared with asymptomatic males, whereas no significant difference was found between asymptomatic and symptomatic females. However, the mean extension-flexion RoM and mean extension-flexion ITS ratios were significantly lower (p = 0.04) in asymptomatic females compared with symptomatic females. Female gender was significantly associated with less extension and flexion ITS in both asymptomatic and symptomatic subjects. Conclusion Males with LBP had significant global ITS weakness when compared with asymptomatic males. Despite no significant ITS difference in symptomatic versus asymptomatic females, LBP caused significant extension-flexion RoM and ITS imbalance in females. These gender-based variations in trunk RoM and IS, especially the extensor-flexor IS imbalance in females, must be considered while designing rehabilitation treatment protocols for LBP.

Resumo Objetivo Determinar as variações na amplitude de movimento (ADM) do tronco e na força isométrica do tronco (FIT) em jovens adultos sintomáticos e assintomáticos baseadas no gênero dos indivíduos. Métodos Neste estudo caso-controle prospectivo, 73 indivíduos com dor lombar (DL) e 80 indivíduos assintomáticos foram analisados. As medidas de ADM do tronco e FIT de extensão, flexão e rotação foram comparadas em ambos os grupos e em subgrupos organizados por gênero. A análise multivariada foi usada para determinar os fatores que influenciam a ADM do tronco e a FIT. Results Symptomatic males had significantly less extension RoM and extension, flexion, and rotation isometric trunk strength (ITS) (p < 0.0001) compared with asymptomatic males, whereas no significant difference was found between asymptomatic and symptomatic females. However, the mean extension-flexion RoM and mean extension-flexion ITS ratios were significantly lower (p = 0.04) in asymptomatic females compared with symptomatic females. Female gender was significantly associated with less extension and flexion ITS in both asymptomatic and symptomatic subjects. Conclusão Indivíduos do sexo masculino com DL apresentaram significativa fraqueza global relacionada à FIT quando comparados com indivíduos do sexo masculino assintomáticos. Apesar de não haver diferença significativa de FIT em indivíduos do sexo feminino sintomáticos versus assintomáticos, a DL impactou a ADM e a FIT de extensão-flexão em indivíduos do sexo feminino. Essas variações de ADM do tronco e FIT baseadas no sexo, especialmente o desequilíbrio extensor-flexor de força isométrica em indivíduos do sexo feminino, devem ser consideradas ao projetar-se protocolos de tratamento de reabilitação para lombalgia.

METHODS: comparative study of 8 patients in an intervention (IG) and kinesiotherapy (CG) group for 8 weeks. The pre- and post-test of glenohumeral internal ROM in both groups was compared using Student's t-test. RESULTS: the myofascial technique group showed a significant increase in glenohumeral internal ROM of 15.2º (p < 0.001), while the control group was not significant (p > 0.05) only 6.4º. CONCLUSIONS: A therapy treatment with Myofascial Release Techniques in patients with shoulder internal rotational deficit is more effective in increasing glenohumeral internal rotational joint range of motion than a traditional, conservative technique.

ABSTRACT The research aimed to evaluate the effect of an Oncology Physical Exercises Program - ONCOFITNESS on the joint range of cancer patients undergoing radiotherapy. The study is considered a randomized controlled clinical trial, being prospective in that it compares the effect and value of an intervention, with prophylactic or therapeutic characteristics, in human beings. The procedures met the standards for researching human beings, and the project was approved. CEP/Hospital Mário Kröeff. Flexibility measurement performed following the LABIFIE protocol, with a Lafayette® brand steel goniometer (USA). The experimental group performed an intervention with Oncofitness. After this period, another evaluation was carried out, following the same procedures. Statistical analysis was performed using SPSS (Statistical Package for the Social Sciences) version 20.0. Sample of 30 men aged GE (X ̅ = 59.0 ± 2.0 years) and CG (X ̅ = 60.0 ± 1.0 years). The data revealed that gains were observed in the EG in knee flexion (∆%=5.0%, p=0.0011x); in hip abduction (∆%=15.8%, p=0.003x); in internal rotation (∆%=8.1%, p=0.0129x) and in shoulder flexion, (∆%=8.3%, p=0.0185x). As was not observed in the CG, Oncofitness provided a reduction in some of the symptoms related to oncological treatments by improving joint range of motion.

High frequency transcutaneous electrical stimulation in the immediate postoperative period of anterior cruciate ligament reconstruction: a randomized clinical trial / Estimulação elétrica transcutânea de alta frequência no pós operatório imediato de reconstrução do ligamento cruzado anterior: um ensaio clínico randomizado

INTRODUCTION: The anterior cruciate ligament (ACL) is an important structure for knee stability. Transcutaneous electrical nerve stimulation (TENS) is an electrical current applied for significant pain relief. OBJECTIVE: To evaluate the effects of high-frequency TENS on the immediate postoperative period of ACL reconstruction. METHODS: 46 patients in the postoperative period of ACL reconstruction were randomly assigned to a control group (CG=23) and a TENS group (TG=23). Knee range of motion (ROM), pain, muscle strength, and drug intake were assessed before surgery and 24 and 48 hours after surgery. The TENS intervention protocol started in the recovery room, shortly after surgery, and was maintained continuously for the first 48 hours after surgery. RESULTS: The TENS group (TG) significantly controlled the increased level of postoperative pain (p<0.05) and significantly increased flexion ROM (p<0.05). When compared to the Control group (CG), the TENS group had a lower intake of ketoprofen (48.27%), diazepam (256.98%), and dipyrone (121.21%), morphine (320.77%), and tramadol (437.46%). CONCLUSION: Continuous high-frequency TENS significantly reduced pain intensity and significantly improved ROM, muscle strength, and drug intake in the postoperative period of ACL reconstruction.

Relação entre o perfil de adesão e as barreiras para a permanência no programa de extensão "yoga: awaken one" / Relationship between the membership profile and the barriers to stay in the "yoga: awaken one" extension program

Objetivo: Investigar a relação entre o perfil de adesão e barreiras percebidas por estudantes universitários para permanência no Programa de Extensão "Yoga: Awaken ONE". Métodos: Foram realizados dois cortes transversais com universitários da Universidade Federal do Recôncavo da Bahia. O primeiro foi composto por 16 indivíduos e investigou o perfil demográfico, socioeconômico, antropométrico, da aptidão física e da qualidade de vida dos universitários que ingressaram no Programa de Extensão. O segundo visou identificar as barreiras para permanência de 13 estudantes (dentre os 16 iniciais) que haviam se afastado do Programa após quatro meses do início. Resultados: Houve predominância de indivíduos do sexo feminino, dos cursos de graduação em Educação Física e Pedagogia e da classe socioeconômica C. A maioria dos participantes estava com indicadores adequados de gordura corporal. Observou-se grande proporção de indivíduos com indicadores baixos de flexibilidade e força muscular. Para a qualidade de vida, a menor mediana foi observada para o domínio meio ambiente e a maior para o domínio relações sociais. As principais barreiras percebidas para a prática de yoga pelos universitários foram "jornada de estudos extensa" e "jornada de trabalho extensa". Observou-se correlação do perfil sociodemográfico, indicadores de obesidade, variáveis hemodinâmicas, flexibilidade, força muscular e qualidade de vida com barreiras percebidas para permanência no Programa de Extensão universitária "Yoga: Awaken ONE". Conclusões: Estes achados sugerem que o perfil do público universitário pode ser determinante para a permanência ou evasão de programas de promoção de exercícios físicos e precisa ser considerado em propostas de programas de extensão universitária.

Objective: Investigate the relationship between the member adherence profile and barriers perceived by university students to remain in the "Yoga: Awaken ONE" Extension Program. Methods: Two cross-sections were carried out with university students from the Federal University of Recôncavo da Bahia. The first was composed of 16 individuals and investigated the demographic, socioeconomic, anthropometric, physical fitness, and quality of life profile of university students joining the Extension Program. The second aimed at identifying the barriers to remain in the program faced by 13 students (out of the initial 16) who had withdrawn from the Program four months after the beginning. Results: There was a predominance of female individuals, from undergraduate courses in Physical Education and Pedagogy, and from the C socioeconomic class. Most participants had adequate body fat indexes. There was a large proportion of individuals with low flexibility and muscle strength. For quality of life, the lowest median was observed for the environment domain, while the highest could be noted for the social relationship domain. The main barriers perceived for the practice of yoga by university students were "long study hours" and "long work hours". There was a correlation between sociodemographic profile, obesity indicators, hemodynamic variables, flexibility, muscle strength, and QOL with the perceived barriers to stay in the "Yoga: Awaken ONE" university extension program. Conclusions: These findings suggest that the profile of the university audience can be a determinant for the permanence or dropout of programs that promote physical exercise and therefore, it should be taken into consideration in proposals for university extension programs.

Flexibility and achilles tendon: a brief review / Flexibilidade e tendão de aquiles: uma breve revisão

Performing flexibility training in an exercise program is important to improve range of motion (ROM). Tendons have a profound impact on the general function of the musculoskeletal system, influence the limitation of ROM, and its structure and mechanical properties can benefit from stretching protocols. The systematic use of lower limbs in locomotion caused the Achilles tendon to become the largest and strongest tendon in the human body. Therefore, understanding the best prescription and frequency of flexibility exercise leads to changes in tendon properties is essential for an appropriate and effective exercise routine. Thus, the aim of this review was to organize and discuss publications about the implications of triceps surae stretching in ROM, as well as its influence on tendon properties. Acute studies show that continuous stretching times between five and 10 minutes cause decreased tendon stiffness, which is not seen in fractionated stretching times less than five minutes. Chronic studies, in turn, also don't present significant results in stiffness with fractionated times and studies with continuous times were not found. Thus, it is not possible to know if a continuous stretching time (longer than one minute) or a total time longer than five minutes but fractionated, can influence the tendon stiffness. (AU)

A realização de treino de flexibilidade como rotina em um programa de exercícios é importante para melhorar amplitude de movimento (ADM). Os tendões têm um impacto profundo na função geral do sistema musculoesquelético, influenciam na limitação da ADM, e sua estrutura e propriedades mecânicas podem se beneficiar de protocolos de alongamento. O uso sistemático dos membros inferiores na locomoção fez com que o tendão de Aquiles se tornasse o maior e mais forte tendão do corpo humano. Portanto, entender qual a melhor prescrição e frequência de exercício de flexibilidade para que ocasione alterações nas propriedades tendíneas é essencial para uma rotina de exercícios adequada e eficaz. Sendo assim, o objetivo dessa revisão de literatura foi organizar e discutir publicações sobre as implicações do alongamento do tríceps sural na ADM, bem como sua influência nas propriedades tendíneas. Estudos agudos mostram que tempos contínuos entre cinco e 10 minutos de alongamento estático causam diminuição da rigidez tendínea, o que não é visto em tempos intervalados inferiores a cinco minutos. Os estudos crônicos, por sua vez, também não apresentam resultados significativos na rigidez com protocolos de alongamento intervalados e estudos com protocolos contínuos não foram encontrados. Dessa forma, não é possível saber se um tempo contínuo de alongamento (superior a um minuto) ou um tempo superior a cinco minutos, intervalado, podem influenciar na rigidez tendínea. (AU)

Does range of motion measurement and reference values differ?: a multi-centered study

This study is aimed to estimate and measure reference values in the normal range of motion of extremity joints in females and to provide a database for the assessment of impairments related to the mobility of the joints. This observational cross-sectional study was conducted at seven major educational institutes areas of Rawalpindi and Islamabad in Pakistan from January to June 2020 with a sample size of 600 healthy females aged 15 to 45 years and divided into three groups through non-probability sampling technique. In study Instruments, an electronic Goniometer was used for the measurement of the range of motions for different joints and then those ranges were recorded. The questionnaire had two sections demographic characteristics and ROM for both upper and lower limbs. Data was analyzed using SPSS V21. A p < 0.05 was considered statistically significant.In the result,Out of 600 participants,there was a statistically significant difference of (p < 0.001) in both upper and lower extremities motion between all the three groups for the measurements and noticeably no significant difference (p > 0.005) between group 1, 2 comparisons for the knee joint extension.To conclude, In most joints, the range of motion increases with age. The transition from group 1 to group 2 was aided by increased hormone participation in growth, an active lifestyle, and generally good health. Because of degenerative changes and joint stiffness, group 3's range of motion deteriorated, leading to a sedentary lifestyle and lack of physical activity. Standardized biomechanical measurements can help health practitioners, such as physiotherapists, choose appropriate therapy interventions to assess musculoskeletal disorders. To resolve the inconsistencies in the reliability and validity of goniometry values, more research is required.
