ABSTRACT
In order to meet the social demand for ultrasound talents, a layered training system of ultrasound medical talents suitable for China's national conditions has been explored. The department of ultrasound of West China Hospital of Sichuan University has formulated and implemented a "three-layers" ultrasound education and training system in combination with its own reality. The first layer mainly refers mastering the basic ultrasound examination ability mainly through relevant ultrasound theoretical knowledge and basic operation skills training. The second layer is based on the first level to further master the ability of ultrasound diagnosis and differential diagnosis of common and frequently occurring diseases in various systems, and to be capable of engaging in basic ultrasound teaching and scientific research. The third layer means mastering the ability of ultrasound diagnosis, evaluation and interventional diagnosis and treatment of difficult and specialized diseases, grasping the latest development direction of the sub-specialty, and having the ability to engage in ultrasound teaching and clinical research. The results show that the "three-layers" ultrasound education and training system conforms to China's national conditions and is worthy of reference and promotion.
ABSTRACT
Objective@#To investigate the prevalence of work-related musculoskeletal disorders (WMSDs) among sonographers in a province of China and influencing factors for WMSDs, and to provide a practical basis for the prevention and treatment of WMSDs in sonographers. @*Methods@#From November 2016 to February 2017, stratified cluster sampling was used to select 700 sonographers from 50 hospitals in this province. A self-designed questionnaire for WMSDs in sonographers was used to investigate general data and the prevalence of WMSDs, and the influencing factors for the prevalence of WMSDs were analyzed. @*Results@#The prevalence rate of WMSDs among these sonographers was 80.22%, and the prevalence rates of WMSDs in the shoulder, the neck, the waist, the back, the wrist, the elbow, the hip, the knee, and the ankle were 74.55%, 68.87%, 63.44%, 57.26%, 53.16%, 45.22%, 37.88%, 30.44%, and 29.24%, respectively. There was a significant difference in the prevalence rate of WMSDs between the sonographers with different ages and working years, and the prevalence rate of WMSDs tended to increase with the increase in age and working years (χ2=20.86 and 18.52, P<0.01) . The multivariate logistic regression analysis showed that female sex (odds ratio [OR]=1.798) , working years >16 (OR=1.004) , weekly working hours >40 (OR=1.616) , poor physical conditions (OR=1.690) , and high work fatigue (OR=1.302) were risk factors for WMSDs in sonographers. @*Conclusion@#There are high prevalence rates of WMSDs in the shoulder, the neck, the waist, the back, the wrist, and the elbow. Sonographers should strengthen self-protection awareness, and effective preventive measures should be adopted to reduce the prevalence rate of WMSDs.
ABSTRACT
OBJETIVO: Avaliar e mensurar o posicionamento escapular e correlacioná-lo com o grau de incapacidade e avaliação funcional de ultrassonografistas. MATERIAIS E MÉTODOS: Dezoito médicos, divididos em grupos sintomático e assintomático em relação à presença de dor por mais de seis meses, responderam a uma entrevista e foram submetidos a avaliação física e aplicação do DASH Brasil. Foi realizada a medida do ângulo de inclinação escapular e avaliação do posicionamento dos membros superiores durante a ultrassonografia. Foram utilizados testes U Mann-Whitney para avaliação do questionário de incapacidade, t de Student para posicionamento do membro superior, ANOVA para inclinação escapular e coeficiente de Spearman para correlação do posicionamento funcional de membros superiores e grau de incapacidade. RESULTADOS: Nas 30 primeiras questões do DASH Brasil houve diferença significativa entre os grupos sintomático e assintomático. No módulo opcional, relacionado ao trabalho, houve diferença significativa entre os grupos. As medidas do inclinômetro apresentaram diferenças significativas entre os grupos no plano frontal em 90° e 120°. Para o ângulo funcional dos membros superiores não houve diferença significativa entre os grupos. CONCLUSÃO: Alterações no ângulo de inclinação escapular podem levar à disfunção dos membros superiores e a aplicação do DASH Brasil pode indicar o grau de dor e incapacidade do indivíduo.
OBJECTIVE: To evaluate and measure the scapular positioning, and establishing its correlation with functional postural analysis and degree of upper extremities disability in sonographers. MATERIALS AND METHODS: Eighteen physicians divided into two groups - symptomatic individuals with pain for more than six months, and asymptomatic individuals - were interviewed and submitted to physical assessment with application of the Brazilian version of the DASH questionnaire. Functional measurements of scapular inclination angles and upper limbs positioning were obtained during the ultrasound scanning. The Mann-Whitney U test was utilized for analyzing the disability questionnaires; the t-Student test, for upper limbs positioning; ANOVA, for scapular inclination angles, and the Spearman's test for correlation between the functional upper limbs positioning and disability degree. RESULTS: A significant difference between symptomatic and asymptomatic groups was observed in the first 30 items of the DASH questionnaire as well as in the four study-related questions. Measurements of scapular positioning presented significant differences between the groups in the frontal plane at 90° and 120°. No significant difference was found for the analysis of functional upper limbs positioning. CONCLUSION: Changes in the scapular positioning may result in upper limbs dysfunction, and the application of the DASH questionnaire can indicate the level of pain and disability of an individual.
