Subject-specific upper extremity modelling

Insight into the mechanical interaction between muscles and bones can be of great help to understand normal function of the human body and to improve diagnoses and treatments of musculoskeletal disorders. This research presented in this thesis aims to improve the predictions of a musculoskeletal model of the shoulder and elbow (the Delft...

Simplified musculoskeletal shoulder model based on a polynomial description

Musculoskeletal shoulder models have been used for many different applications. Up till now, these models have not been suited to operate in a real-time environment. This study uses the most cited and used musculoskeletal shoulder model in the field, Delft and Elbow and Shoulder Model (DESM), and changes the structure to make the model quicker....

Shoulder load during handcycling at different incline and speed conditions

Background The manual wheelchair user population experiences a high prevalence of upper-limb injuries, which are related to a high load on the shoulder joint during activities of daily living, such as handrim wheelchair propulsion. An alternative mode of propulsion is handcycling, where lower external forces are suggested to be applied to reach...

Development of a comprehensive musculoskeletal model of the shoulder and elbow

The Delft Shoulder and Elbow Model (DSEM), a musculoskeletal model of the shoulder and elbow has been extensively developed since its introduction in 1994. Extensions cover both model structures and anatomical data focusing on the addition of an elbow part and muscle architecture parameters. The model was also extended with a new inverse...
