iShear is the first clinical tool to measure Total Shear Force* (tendency to slide) in the seat plane. It helps to minimise sliding forces when setting up a wheelchair. It can be used on almost every common wheelchair by placing it underneath the cushion. No change in the client-seat base interface is required. Once installed, you can use the free iShear app for real time data monitoring.
A pressure map is simply a pad with sensors that is placed on a wheelchair cushion. The patient transfers onto the pad and cushion and the system will provide either a snapshot or a live feed of the pressures under the seated surface. Systems are typically colour coded with light blue being the least pressure to red being the most pressure.
The map is used to determine the source of any problems. The therapist can check the pressure areas when the back angle/support is altered or when the lower extremities are repositioned. The cushion or alternate cushions can be modified to see if they map differently. Getting to the cause of a persistent pressure injury can be a challenge, and a pressure map can facilitate a much faster result.
