Vicair® iShear

World's first clinical tools to measure *total shear force in a wheelchair seating system

Help evaluate the positioning of a person in a seating system

*Total Shear Force (TSF): The total shear force in the seat plane measured by the iShear is the anterior-posterior force parallel to the seat plane. It’s measured between the cushion and the seat base interface.
