Desequilíbrio muscular dos flexores e extensores do joelho associado ao surgimento de lesão musculoesquelética relacionada à corrida: um estudo de coorte prospectivo

ResumoO objetivo deste estudo foi verificar se o desequilíbrio dos músculos do joelho pode estar associado com o surgimento de lesões em corredores. Vinte corredores fizeram uma avaliação isocinética nas velocidades de 60, 180 e 300o/s e foram acompanhados por três meses para verificar a ocorrência de lesões. Quatro atletas (21%) apresentaram lesões que envolveram a região do joelho e o desequilíbrio muscular encontrado foi associado ao surgimento de lesões, nas três velocidades testadas (p<0,05).AbstractThe aim of this study was to determine whether a muscle imbalance of the knee is associated with running injuries. Twenty runners were evaluated by an isokinetic dynamometer at 60, 180 and 300 degrees/second. Runners were followed for three months to determine the incidence of injuries. We used the chi‐square test to verify the association between muscular imbalance and the appearance of injury. Four athletes experienced injuries (21%), all registered in the knee. Muscle imbalance was associated with running‐related injuries for the three tested velocities (p<0.05). To conclude, a muscle imbalance may be associated with running injuries

Prevalence of musculoskeletal pain in walkers: a cross-sectional study

Este artículo tuvo el propósito de verificar la prevalencia de dolor musculo esquelético en practicantes de caminatas y los posibles factores asociados a esta práctica. Se trata de estudio transversal, que se realizó mediante un cuestionario aplicado a los practicantes de caminatas en parques y lugares que son comunes a esta actividad. El cuestionario se componía por informaciones personales de los practicantes, la rutina de la práctica, el historial de lesiones y la presencia de dolor musculo esquelético durante la entrevista. Para ello, se ha hecho un análisis descriptivo de las características de los participantes, y se han utilizados la prueba t independiente, la prueba de Mann-Whitney y la prueba de Chi Cuadrado para la comparación de los datos entre los participantes con y sin dolor en la ocasión de la entrevista. Se han entrevistados 136 practicantes de caminatas, y el 8% fue la prevalencia de dolor musculo esquelético encontrada. La zona más afectada por el dolor entre los participantes fue la articulación de rodilla (45%). Entre las variables evaluadas, se ha demostrado que la presencia de lesiones previas de los últimos 12 meses está asociada estadísticamente (pO presente estudo teve como objetivo verificar a prevalência de dor de origem musculoesquelética em praticantes de caminhada e os possíveis fatores associados.

Foi realizada uma análise descritiva das características dos participantes e utilizado o teste t independente, teste de Mann-Whitney e teste de qui-quadrado para a comparação dos dados entre os participantes com dor e sem dor no momento da entrevista. Foram entrevistados 136 praticantes de caminhada, sendo que a prevalência de dor musculoesquelética foi de 8%. A articulação do joelho foi a região mais acometida pela dor entre os participantes (45%).

Improving Completeness and Transparency of Reporting in Clinical Trials Using the Template for Intervention Description and Replication (TIDieR) Checklist Will Benefit the Physiotherapy Profession

Incomplete reporting of interventions in physiotherapy studies is an important problem and The Journal of Manual and Manipulative Therapy endorses the use of the TIDieR checklist as a potential solution

Prevalência de dor musculoesquelética em corredores de rua no momento em que precede o início da corrida

A participação em corridas de rua vem aumentando significativamente nos últimos anos, motivada pelos benefícios a saúde, fácil execução e baixo custo. Os objetivos desse estudo foram: analisar a prevalência de dor musculoesquelética em corredores de rua no momento em que precede o início da prova, além de discutir alguns fatores etiológicos relacionados à prática da corrida. Os participantes foram divididos em dois grupos, um grupo foi composto por corredores com queixa de dor musculoesquelética e outro sem queixa. Foi constatada uma diferença estatisticamente significante quando comparados o número de treinos por semana (p=0,03) e a quilometragem semanal percorrida (p=0,01). Concluímos que a prevalência de dor foi de aproximadamente 25% e estava diretamente associada ao volume de treino semanal

What is the foot strike pattern distribution in children and adolescents during running? A cross-sectional study

Background: There is a lack of studies describing foot strike patterns in children and adolescents. This raises the question on what the natural foot strike pattern with less extrinsic influence should be and whether or not it is valid to make assumptions on adults based on the knowledge from children. Objectives: To investigate the distribution of foot strike patterns in children and adolescents during running, and the association of participants’ characteristics with the foot strike patterns. Methods: This is a cross-sectional study. Videos were acquired with a high-speed camera and running speed was measured with a stopwatch. Bayesian analyses were performed to allow foot strike pattern inferences from the sample to the population distribution and a supervised machine learning procedure was implemented to develop an algorithm based on logistic mixed models aimed at classifying the participants in rearfoot, midfoot, or forefoot strike patterns. Results: We have included 415 children and adolescents. The distribution of foot strike patterns was predominantly rearfoot for shod and barefoot assessments. Running condition (barefoot versus shod), speed, and footwear (with versus without heel elevation) seemed to influence the foot strike pattern. Those running shod were more likely to present rearfoot pattern compared to barefoot. The classification accuracy of the final algorithm ranged from 80% to 88%. Conclusions: The rearfoot pattern was predominant in our sample. Future well-designed prospective studies are needed to understand the influence of foot strike patterns on the incidence and prevalence of running-related injuries in children and adolescents during running, and in adult runners

What Do Recreational Runners Think About Risk Factors for Running Injuries? A Descriptive Study of Their Beliefs and Opinions

R unning is one of the most popular types of physical activity worldwide. The benefits attributed to recreational running include improvements in physical and mental health, weight control, stress reduction, and social participation. T T OBJECTIVES: To describe the beliefs and opinions of runners about risk factors associated with running injuries. T T BACKGROUND: Despite the health benefits of running, a high prevalence of injury has been reported in runners. Preventive strategies for running injuries may be more successful with a better knowledge of runners&apos; beliefs. T T METHODS: A semi-structured interview of recreational runners was based on the question, &quot;What do you think can cause injuries in runners?&quot; Analysis of the interviews was performed in 3 steps: (1) organizing the data into thematic units, (2) reading and reorganizing the data according to frequency of citation, and (3) interpreting and summarizing the data. The runner interviews were continued until no new beliefs and opinions of runners regarding injuries were being added to the data, indicating saturation of the topic. T T RESULTS: A total of 95 recreational runners (65 men, 30 women) between the ages of 19 and 71 years were interviewed. Of those interviewed, the average running experience was 5.5 years and approximately 45% had experienced a runningrelated injury in the past. The factors suggested by the runners were divided into extrinsic and intrinsic factors. The most cited extrinsic factors were &quot;not stretching,&quot; &quot;excess of training,&quot; &quot;not warming up,&quot; &quot;lack of strength,&quot; and &quot;wearing the wrong shoes.&quot; For the intrinsic factors, the main terms cited were &quot;not respecting the body&apos;s limitations&quot; and &quot;foottype changes.&quot; T T CONCLUSION: Recreational runners mainly attributed injury to factors related to training, running shoes, and exceeding the body&apos;s limits. Knowing the factors identified in this study may contribute to the development of better educational strategies to prevent running injuries, as some of the runners&apos; beliefs are not supported by the research literature
