ISG Events at ISB

Dear Friends,

Based on your replies we got in touch with the ISB organizers to arrange a session on Shoulder Biomechanics at the ISB 2009. Moreover, we asked the organizers for a room to have a discussion about these two topics, plus others that will come:

  1. Definition of standardized protocol for upper-limb motion analysis: a follow-up on the 2005 proposal paper: does it work?
  2. Agreement between shoulder models prediction and experimental evidence: is it not time to start validating?

As for point 1, we think the following papers might be useful for the discussion:

  • Wu et al - ISB standard
  • Kontaxis et al (2009) A framework for the definition of standardized protocols for measuring upper-extremity kinematics. Clin Biomech (Bristol, Avon). 2009 Feb 4. [Epub ahead of print] - PMID: 19200628

If you have others, just write me and I'll collect the sugestions.

DirkJan also proposed having an informal breakfast or lunch with both students and senior members of the ISG. This can be a nice chance to know better each other and for students to ask questions in a very informal situation.

Finally, as now we all have received the decisions about our abstract, it would be good to know how many of us will be at the conference. For this and other suggestions, just write me.

Hi Andrea,

It is a good initiative to organize a shoulder session and a discussion meeting at the ISB. I support the proposed topic on model validation but from a different point of view. Attempts for comparing model simulations and experiments have already been made and the time aspect is not the issue.

The actual issue in my opinion is the comparability of conditions of the model simulations and the experiments: mechanical optimality versus physiological optimality (including the mechanical), especially under pathological conditions. The model handles the mechanical equilibrium and is an important tool to reduce the 'solver space' in explaining the experimental observations.

Best regards,
