iShear is world’s first tool to measure total shear force in the seat of a wheelchair. It is placed under the cushion and communicates the results to a free to download app through a bluetooth connection.
The total shear force (TSF) 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.
Sliding is a huge clinical problem but difficult to quantify. Until now! This smart device measures Total Shear Force, helping you evaluate the positioning of a person in a seating system.
