ABSTRACT Introduction: The assessment of biomechanical changes related to the lower limbs is necessary in clinical practice to measure the potential risks of injury and the influences on existing dysfunction. Biomechanical changes related to previous ankle injuries are known to influence the performance of the entire lower limb. Objective: The aim of this study was to correlate muscle strength tests, performance tests and ankle stability with the Single Hop Test (SHT). Methods: 82 amateur runners were evaluated with isokinetic tests of quadriceps and hamstring muscle strength, as well as Y Balance Test (YBT), Weight-bearing Lung Test (WBLT), and the SHT. Results: The results showed there was a significant correlation between the SHT and the YBT in subjects with hamstring/quadriceps ratio (I/Q ratio) <0.55, and the length of the unilateral SHT with the peak torque of ipsilateral knee extensors. Conclusion: The study was successful in correlating the functional tests in question with the results obtained in isokinetic dynamometry. Level of Evidence V; Cross-Sectional Study.

Mobile phone usage among nigerians: risk factors for musculoskeletal injuries and preventive strategies

Aims: The increase in the usage of hand-held devices (HHDs) and smartphones (SPs), especially in Nigeria has resulted in an upsurge of musculoskeletal complaints. The aim of this study was to determine the incidence and risk factors for musculoskeletal injuries due to mobile phone usage among Nigerians and the preventive strategies. Materials and Methods: This study involved 630 male and female participants above 18 years old who were purposively recruited across designated study centres in public places. The instrument used was a questionnaire specifically designed to suit the Nigerian culture and environment and developed from previously validated questionnaires. Data were exported to Statistical Computing Programming R version 4.0.5 for analysis and Chi-square was used to compare the characteristics of those who experienced injury using SPs/HHDS and those who did not. Independent variables with a 95% confidence level and P < 0.05 in the multivariate model were considered statistically significant. Results: The most common daily use of SPs/HHDS by the participants was phone calls (98.4%) followed closely by social networking (96.0%) while the occupation and educational level of the participants had statistically significant (P < 0.05) impact on musculoskeletal injuries. The type of mobile device and the time spent using these devices were also significant (P < 0.05) risk factors for injuries. Some self­treatment strategies adopted by the participants were all significantly (P < 0.05) associated with reduction of musculoskeletal discomfort. Conclusion: The occupation, educational level, the types of mobile devices and time spent using the devices were risk factors for musculoskeletal injuries

Prevalence and Pattern of Musculoskeletal Injuries Among Malaysian Hockey League Players

@#Introduction: Hockey is a team sport that involves running, sprinting, and making sudden changes in directions of movement to control a ball against the opposing team. Therefore, due to its nature of fast movement, hockey players may be at risk of various musculoskeletal injuries. This study aimed to identify the prevalence and pattern of musculoskeletal injuries sustained among Malaysian Hockey League players. Materials and Method: Data were collected from 84 field hockey players that participated in the Malaysian Hockey League competition from June 2016 until December 2016. All injuries were recorded by the participating medical team using a structured questionnaire. A descriptive statistical analysis and Chi-Square test were used to explore the prevalence of the injury. Result: More than half of the players were reported to have lower limb injuries (51.6%). Sprain and strain were the most prevalent injuries (63%) and mostly affected the ankle (29%). Male players sustained more injuries (50.8%) compared to female players (49.2%). Conclusion: This study suggests that a guideline is needed for injury prevention strategies that will benefit the hockey players in preventing injuries.

Determining the relationship between physical status and musculoskeletal injuries in children: a cohort study / Journal of Rural Medicine

Background: In Japan, in 2016, the School Health and Safety Act was revised and examination of extremities in addition to scoliosis became mandatory. Musculoskeletal examinations were subsequently started using a mark sheet-type questionnaire. In the present study, we aimed to analyze the relationship between physical findings and musculoskeletal problems and propose a preventive strategy for musculoskeletal injuries.Methods: In 2017, a total of 4,073 elementary and middle school students underwent direct musculoskeletal examination. In a direct examination, the following elements were included: torticollis; scoliosis; stiffness of the shoulder, elbow, hip, knee, and ankle; flexion and extension in standing position; flat foot; hallux valgus; and alignment of the upper and lower extremities. Of the 4,073 students who underwent direct examination in early 2017, only 3,754 were able to complete the mark sheet-type questionnaires in early 2018. A prospective longitudinal analysis of the data gathered was performed.Results: A total of 396 (11%) students had injuries. The ankle sprain/non-ankle sprain group comprised 119 (3%)/3,635 (97%) students, while the fracture/non-fracture group comprised 105 (2.8%)/3,650 (97.2%) students, respectively. Comparing the sprain group with the non-sprain group, ankle stiffness significantly correlated with ankle sprain in the univariable and multivariable analyses. Injuries occurred more frequently among boys, older students, students with stiff bodies, and students who were involved in sports activities of longer duration.Conclusion: Ankle stiffness was assumed to be a risk factor for ankle sprain. Stretching of the ankle might be effective for preventing ankle sprain. However, further interventional studies are needed to confirm this finding.

Associated factors and profile of injuries in professional ballroom dancers in Brazil: a cross-sectional study

Abstract Aims: Ballroom dance consists of a modality characterized by fast and dynamic movements performed in pairs, aiming at technical and artistic excellence. Objective: To analyze the prevalence, characteristics, and factors associated with injuries in professional ballroom dancers, considering possible differences between sexes. Method: 320 professional dancers of both sexes with a mean age of 31.48±8.63 years, who were in professional companies and/or dance schools from five regions of Brazil. The measurement was performed through an online self-administered questionnaire about general information and injuries. Results: A high frequency of musculoskeletal injuries (80.0%) was observed, especially osteoarticular ones (52.4%). In women, the lower limbs were the anatomical location most reported (31.1%) and the knee in male dancers (28.7%). Overweight men, with more than 11 years of dance practice, who danced in companies and also performed other physical activities, were more likely to have injuries. However, women were less likely to have injuries when they were overweight and more likely when they practiced other dance modalities besides ballroom dancing. Conclusions: Approximately 64.1% of ballroom dancers suffered an injury throughout their professional careers. For men, being overweight as well as the search for complementary activities to the physical training routine for both sexes, seem to influence the occurrence of injuries. Identification of the factors associated with injuries in ballroom dancers contributes both to preventive actions and to rehabilitation processes, favoring a healthy and safe career for professionals involved in this practice.

A painful symphony: the presence of overuse syndrome in professional classical musicians / Una sinfonía dolorosa: la presencia del síndrome de uso excesivo en músicos clásicos profesionales

Musculoskeletal problems are common in instrumental musicians. Little is known about the factors that place musicians at risk, and the ways in which musicians can prevent these problems. Overuse syndrome is the most reported diagnosis among instrumental musicians suffering from playing related musculoskeletal injuries. The study group comprised 50 musicians employed in Symphony Orchestra of the Serbian National Theatre of Novi Sad. Out of the 50 musicians, 30 (60 %) are male and 20 (40 %) female. Higher frequencies of the presence of musculoskeletal symptoms were neck, region of trapezius, back, shoulder, wrist, hand and arm. A larger number of musicians (81.8 %) had perception of high demand of the profession. This investigation with professional classical musicians should show the music-medical interest.

Los problemas musculo-esqueléticos son comunes en los músicos instrumentales. Poco se sabe sobre los factores que ponen en riesgo a los músicos y las formas en que los ellos pueden prevenir estos problemas. El síndrome de uso excesivo es el diagnóstico más informado entre los músicos instrumentales que sufren lesiones musculo-esqueléticas relacionadas al uso de instrumentos musicales. El grupo de estudio estuvo compuesto por 50 músicos de la Orquesta Sinfónica del Teatro Nacional Serbio de Novi Sad. De los 50 músicos, 30 (60 %) eran hombres y 20 (40 %) mujeres. La frecuencia más alta de presencia de síntomas musculoesqueléticos se produjo en el cuello, músculo trapecio, espalda, hombro, muñeca, mano y brazo. Un mayor número de músicos (81,8 %) tuvo una percepción de alta demanda de la profesión. Esta investigación con músicos clásicos profesionales debería ser de interés médico-musical.

Prevalence, severity and characteristics of work-related musculoskeletal disorders amongst obstetrics and gynaecology professionals

Background: Backache is a common cause of morbidity among doctors and 50% of the obstetricians and gynaecologists suffering from this attribute it to working posture. Occupational injuries are poorly analyzed amongst these professionals. Work related injuries have adverse effect on health and work performance due to discomfort caused by pain. Awareness of ergonomics, correct posture and strategical assessment of risk factors is needed for the prevention of work related musculoskeletal injuries amongst obstetricians and gynaecologists.Methods: A survey based study was performed. Informed consent was taken for participation. The questionnaire included 16 questions categorised into: demographics; injury data; impact of injury; and general mental health. Hard copy of the questionnaire and online forms of the questionnaire were used to complete the data collection.Results: The response rate for the survey was 85% of the doctors who reported to have experienced pain in the last year. The most common site was back, which was followed by the neck and knees. 71.4% of doctors reported injuries attributed to work.Conclusions: The result demonstrates the prevalence of work related musculoskeletal injuries and their effects. These injuries are highly underreported. Ergonomics and work related injury prevention in this profession is a suggestion for solution as more data is needed regarding the analysis and risk factor assessment.

Incidence rate of musculoskeletal injuries in brazilian army / Taxa de incidência de lesões musculoesqueléticas no exército brasileiro

The incidence of musculoskeletal injuries (MSIs) is a constant concern in all Armed Forces. Among risk factors for MSIs, physical training and sports can be considered the most frequent cause in military. In this sense, the aim of this study was to investigate the incidence rate of musculoskeletal injuries, identifying the anatomical distribution and its association with risk factors such as: body composition, age and physical training over the past 12 months. Three hundred fifty-one male cadets from the first year of the Brazilian Army officers training course and four hundred and fifty six students from the logistics sergeants training course (three hundred seventy-five male and eighty one female) volunteered to fill in a self-reported questionnaire which was developed based on a literature review and the clinical experience of the investigators. It contained questions concerning anatomical site of the MSIs, hours of physical activities per week, type of activities at the moment of injury and days of absences in physical activities. Among 807 subjects studied, 180 military have reported 220 MSIs. From this total, 143 have presented a single injury, 34 have suffered two injuries and three subjects have had three injuries each one during the last 12 months. Knee was the anatomical site with the higher incidence (7.06%) of MSIs over a 12-month period. Running was the activity with the higher incidence (11.77%) of injuries over a 12-month, accounting for 43.18% of all MSIs. When considered all activities of physical training, the MSIs incidence rate over a 12-month was 17.97%, which represents 71.36% of all MSIs. In young militaries, the largest amount musculoskeletal injuries occurred in the lower extremities and during military physical training, with running being the main activity in which the injuries occurred. Population, gender and body composition was not significantly associated with these types of injuries, while older age was associated in this study. The gradual and systematic progression of distance and speed during running training should be emphasized to prevent MSIs. (AU)

A incidência de lesões musculoesqueléticas (LME) é uma preocupação constante em todas as Forças Armadas. Entre os fatores de risco para LME, treinamentos físicos e esportes podem ser considerados a causa mais frequente em militares. O objetivo deste estudo foi investigar a taxa de incidência de lesões musculoesqueléticas, identificar a distribuição anatômica e sua associação com fatores de risco, tais como: composição corporal, idade e treinamento físico nos últimos 12 meses. Trezentos e cinquenta e um cadetes do primeiro ano da Escola Preparatória de Cadetes do Exército brasileiro e quatrocentos e cinquenta e seis alunos do curso de Sargento logístico (trezentos e setenta e cinco homens e oitenta e uma mulheres) se ofereceram para preencher um questionário auto relatado que foi desenvolvido com base em uma revisão da literatura e a experiência clínica dos pesquisadores. Ele continha perguntas sobre o local anatômico das LME, horas de atividades físicas por semana, tipo de atividades no momento da lesão e dias de ausência em atividades físicas. Entre 807 sujeitos estudados, 180 militares relataram 220 LME. A partir deste total, 143 apresentaram uma única lesão, 34 sofreram duas lesões e três indivíduos tiveram três lesões cada nos últimos 12 meses. O joelho foi o local anatômico com maior incidência (7,06%) de LME ao longo de um período de 12 meses. A corrida foi a atividade com maior incidência (11,77%) de lesões ao longo de 12 meses, representando 43,18% de todas as LME. Quando considerado todas as atividades de treinamento físico, a taxa de incidência de MSI ao longo de um período de 12 meses foi de 17,97%, o que representa 71,36% de todas as LME. Em militares jovens, a maior quantidade de lesões musculoesqueléticas ocorreu nas extremidades inferiores e durante o treinamento físico militar, sendo a corrida a principal atividade na qual ocorreram as lesões. População, gênero e composição corporal não foram significativamente associados a esses tipos de lesões, enquanto a idade avançada foi associada neste estudo. A progressão gradual e sistemática da distância e da velocidade durante o treinamento em corrida deve ser enfatizada para evitar LME. (AU)

El análisis multifactorial del trabajo estático y repetitivo. Estudio del trabajo en actividades de servicio / The Multifactorial Analysis of Static and Repetitive Work. Study of the Work in Services Activities

El trabajo de oficina y, específicamente, el trabajo con computador se realizan en períodos prolongados de trabajo estático, lo que se asocia con el desarrollo de desordenes músculo esqueléticos. En consecuencia, los autores desarrollaron un estudio transversal, a partir de la evaluación de trabajadores de oficina (n=377) de una empresa dedicada a actividades de servicio (gestión de información y atención al cliente), con el objetivo de explorar la relación entre la estructura del trabajo, la naturaleza de las tareas y la presencia de problemas osteomusculares e identificar los principios de una estrategia que estimule la transición postural. La información se recolectó a través de un formulario que indagó sobre variables relativas al tipo de cargo que desempeña el trabajador, el tiempo dedicado a actividades informáticas, incapacidades, antecedentes médicos y sintomatología actual. Como principales antecedentes médicos en la población evaluada se encontró: hipertensión arterial (HTA), 8%; dislipidemia, 23%; diabetes, 3%, e hipoglicemia, 4%. En los trabajadores evaluados se encontró que el 80% refiere dolor, específicamente relativo al miembro superior: manos, 26%; codos, 3%, y hombros, 4%. En columna cervical, 32%; lumbar, 16%, y dorsal, 6%. Finalmente, se evidenció que el 80% del tiempo laboral del personal estudiado es empleado en actividades de trabajo estáticas, dedicadas en su mayoría a la digitación de datos. Los resultados de este estudio se aplican al desarrollo de principios para el diseño de tareas y de una estrategia que busca potenciar las transiciones de postura en el trabajo.

The office work and specifically the work with computer are develop in long periods of static work, which is associated with the development of muscle skeletal disorders. In consequence, the authors made a transverse study with office workers (n=377) of a company dedicated to service activities (management of information and attention to costumers) in order to explore the relationship between the work structure, the nature of the tasks and the presence of muscle skeletal disorders, and to identify a strategy to stimulate the postural transition. The information was collected in a question paper that went into variables related to the type of task that the worker develops, the time that he dedicates to office and computer activities, disabilities, medical precedents and current symptomatology. The main medical precedents founded in the evaluated population was: arterial hypertension (HTA), 8%; lipidomics, 23%; diabetes, 3%, and hypoglycemia, 4%. In the evaluated population was found that 80% suffer pain, specifically relative to upper limbs: hands, 26%; elbows, 3%, and shoulders 4%. In cervical column, 32%; lumbar column, 16%; and dorsal column, 6%. Finally, it was proved that 80% of the worker’s time is dedicated to static work, specifically to typing information. The results of this study are applied to the development of principles to design tasks and to develop a strategy to promote the posture transitions at work.

Musculo-skeletal complications in seizure disorders

Eight cases of musculo-skeletal injuries secondary to seizures of various causes treated between 1979 and 1983 are presented. A comprehensive review of the literature shows that these injuries are quite common occurrences in the convulsive therapy of psychiatric patients. These seizures have since, been prevented by the use of general anesthesia, muscle depolarizing agents and newer drugs introduced in psychiatric therapy. Physical restraint may in fact produce these injuries during seizure and avoidance may be more beneficial to the patient. The musculo-skeletal complications are quite varied and orthopedic management is individualized.(Summary)
