3 Product description
The iShear is a medical device that measures the sliding force in the seat plane of a client sitting
in a wheelchair. The iShear app is the user interface of the product.
In this manual ‘sliding force’ will be referred to as ‘TSF’, as explained in 3.1.1.
By using the iShear and iShear app you can measure the TSF in dierent wheelchair set-ups and
create a situation in which TSF is as low as possible. This decreases the negative eects of TSF on
the client.
3.1 TSF
3.1.1 Explanation of TSF
The total shear force in the seat plane measured by the iShear is the anterior-posterior force
parallel to the seat plane. It is measured between the cushion and the seat base interface. From
now on we will refer to this as TSF. This paragraph further explains this denition.
In Figure 2 the client is sitting upright in the wheelchair. The forces shown in gure 2 are the
vertical forces, perpendicular to the seat plane. The weight of the client pushes down on to the
cushion (gravity – green arrows) and the cushion ‘pushes back’ with a force in the opposite
direction (normal force – red arrows).
In Figure 3, the client is leaning against the back support. This situation introduces horizontal
forces, parallel to the seat plane. Besides the vertical forces, the client exerts a horizontal force
into the back support and the back support ‘pushes back’ with a horizontal force in the opposite
direction (red arrow in back support).
In addition, there are horizontal forces in the seat plane. Because the client is pushing back in
the back support his/her body consequently pushes forward in the seat plane (green arrow in
seat plane). This horizontal force in the seat plane is the ‘sliding force’ and what is referred to as
the TSF in this document. The red arrow in the seat plane is the friction force.

3.1.2 Wheelchair settings that inuence TSF
In a clinical setting, the TSF can be inuenced by setting up the wheelchair and its components.
TSF variations can be expected with variations in (e.g.):
• Seat angle
• Back angle
• Tilt angles
• Foot supports
• Back support interventions
• Shell back supports
• Tension adjustable back supports
• Custom molded back supports
• Non-adjustable back supports
• Propulsion (hand and foot propulsion)
• Secondary support systems

5.4 Removing the iShear after measuring
• Do not remove the iShear when the client is seated on the cushion.
• Do not pull at the sensor bar and/or use excessive force when
removing the iShear.
• Always store the iShear in the original iShear carrying case after each
session.
• Do not fold the iShear in any other way than in the way it is originally
placed in the storage case.
• Do not place any objects on top of a folded iShear.
Remove the iShear from the wheelchair:
1. Transfer the client out of the wheelchair.
2. Remove the seat cushion from the wheelchair.
3. Remove the iShear and press the on/o button on the sensor bar for 2 seconds to turn the
iShear o. The blue light rst ashes rapidly before it turns o.

6. Place the iShear in the carrying case (see 6.3).
5.5 Working with saved measurements
• Measurement data and patient data are not in any way collected or
stored by Vicair.
• Within the app you have the option to store patient information. It is
the user’s responsibility to safeguard this (sensitive) patient
information.
• Measured values can be dierent with dierent client weight.
• The iShear is not a product selection tool
• Friction in the back system could create a dierent TSF value
• The values measured by the iShear do not provide an indication of
the risk of tissue damage.
• Because of internal friction measured values between -2 kg and 2 kg
are less accurate.
