ISB Shoulder Protocol

ISB Shoulder Protocol

The International Society of Biomechanics, the International Shoulder Group and the Delft University have proposed a protocol for the study of shoulder mechanics. The protocol provides a definition of local coordinates systems for each of the relevant body segments including trunk, clavicle, scapula and humerus. It also identifies alternative methods for determining the location of the gleno-humeral joint center of rotation. Finally, it suggests alternative Euler angles and rotation sequences to be used when reporting the movement of segments.

The MotionMonitorä’ has generalized the protocol to enable application of the protocol as proposed together with adaptations. It eases implementation of the protocol with a series of drop down menus that guide the user through each step of the protocol. Specifically, the The MotionMonitorä

	permits attachment of sensors to trunk, clavicle, scapula and humerus using surface markers, bone pins, or “scapula locators” as suggested by the protocol,
	provides for digitization of local coordinate axes for each segment using the landmarks specified by the protocol or alternatives as determined by the researcher,
	supports location of the gleno-humeral joint center by digitization of a centroid; rotation of the humerus; or, by offset from scapular landmarks determined by the regression analysis of Meskers et. al, and
	reports euler angles relative to any reference frame including the world and each of the other segments. The user can also specify any rotation sequence by selection from convenient drop down menus.
