I am a fairly new user of AnyBody.7.2. AMMR.v2.2.1. I am interested in using the BergmannGH model to predict the JRF during arm abduction and have several questions.
When running the simulation without modifying the script, the JRF are not equivalent to as shown in the webcast 'Validation of the AnyBody version of the Dutch Shoulder Model by the in-vivo measurement'. I'm aware that this webcast was broadcasted 13 years ago in 2007. Have there been any changes to the model which resulted in different values? In detail, each JRF component is approximately 100N lower than predicted.
I want to implement the scapulohumeral rhythm for arm abduction up to 90-degree. To my understanding, I can do so by including the following statement at the beginning of the main script:
#define BM_ARM_SHOULDER_RHYTHM ON
Then I deleted the joint driver for Sternoclavicular to avoid over-constraint. However, I am not getting similar results to Bergmann's data beyond 45-degree. Is this the correct approach?
- Is there a reason why the BergmannGH is validated up to 45-degree only?
