About the ISG


The International Shoulder Group is a collaboration of mostly biomechanically oriented research groups, whose main interest is in the shoulder. A board comprising five members heads the ISG. Elections are generally held by e-mail, unless members of the ISG request otherwise. The Conference of the ISG takes place every two years (alternating with the ISB Conference), and symposia are organised at other biomechanics and related meetings. The constitution of the ISG can be found here.


The International Shoulder Group was started at the Congress of the International Society of Biomechanics at UCLA (Los Angeles) in 1989. To date the group comprises approximately 80 researchers from over 20 different countries. The International Shoulder Group was awarded the status of 'technical group' of the International Society of Biomechanics (ISB) at the conference held in Calgary in 1999.


The goal of the International Shoulder Group is to enhance shoulder research by exchanging ideas, methodologies, data and results. To this end the exchange of preprints and PhD-theses, as well as students and researchers is encouraged.


One of the objectives of the International Shoulder Group is to make input data for modelling of the upper extremity more easily available. As a start, most of the data of the Dutch Shoulder Group are now available on Internet. The database comprises data from two studies: shoulder dissection data from seven conserved specimens, and arm dissection data from four fresh specimens (one two-sided). The latter study was a joint project of the VU Amsterdam and the Mayo Clinic, Rochester (MN). See the overview for further information.


The International Society of Biomechanics strives towards the standardization of the motion description of joints. Recently, a small committee of the International Shoulder Group, presided over by Frans van der Helm contributed to a recommendation for the standardized description of upper extremity motion. The full text of these recommendations can be found in the Journal of Biomechanics (see Wu et al., Journal of Biomechanics, 2004).
