Methods: A general questionnaire was applied to identify left-handed students in a population of 750 students, enrolled in clinical courses. An adaptation of the Grad-Corllet Diagram and a specific questionnaire on clinical practices were applied to the selected students. Descriptive statistics was utilized to analyze data of the specific questionnaire, and Mann-Whitney statistics, chi-square or Fisher’s Exact tests (with a 5% significance level) were utilized for the Grad-Corllet Diagram, searching for an association be- tween discomfort/pain in different body regions and manual laterality. Results: All students presented higher percentage of pain in the lumbar and neck/cervical re- gions. However, left-handed students presented higher values, with statistical signifi- cance levels of p = 0.041 for lower back, p = 0.002 for neck and p = 0.003 for cervical region. Conclusions: The majority of left-handed students classified “moderate” the difficulty of working with equipment designed for right-handers. There was high frequency of musculoskeletal pain/discomfort, with relevant statistical results for left- handed students regarding intensity. It is suggested that the participating institutions evaluate the adoption of inclusion politics, re-adapt the infrastructure to include equipment designed for left-handers, and finally provide adequate work conditions for all students.展开更多

In the past 30 years, its research methods have been the focus of debate in regard to its academic direction, academic position, and academic path. These three ＂academic problems＂ should be paid attention because they not only sustain our current research and construction of Music Iconography＇s future and destiny, but also become major theoretical and practical issues. The author advocates that the academic direction should maintain highly consistent with the reality of China, as well as the academic practice. In order to guarantee the academic direction and academic position, we should adopt the academic path from these two aspects： ＂the horizontal logic＂ and ＂the longitudinal logic＂展开更多
