The Delft Shoulder and Elbow Model (DSEM), a musculoskeletal model of the shoulder elbow has been extensively developed since its introduction in 1994. Extensions cover both structures anatomical data focusing on addition an part muscle architecture parameters. was also extended with new inverse-dynamics optimization cost function combined inverse-forward-dynamics models. This study is update developments over last decade including qualitative validation different simulation architectures available DSEM. To validate model, dynamic forward flexion motion performed by one subject, which surface EMG-signals 12 superficial muscles were measured. Patterns model-predicted relative forces compared their normalized EMG-signals. Results showed relatively good agreement between EMG (mean correlation coefficient 0.66). However, for some cases, no force predicted while activity had measured (false-negatives). DSEM used potential to be variety clinical biomechanical applications.
