KEY CONSIDERATIONS FOR SEATING ASSESSMENTS
A recent social media poll carried out by specialist seating manufacturer, Seating Matters, revealed that 56% of Occupational Therapists lacked confidence when carrying out a seating assessment.
- provides the required postural support;
- protects the users’ skin and prevent pressure injuries;
- offers high levels of comfort;
- and ensures safety against falling from the chair.
1. What range of movement and mobility does the client have?
2. What are the main goals to be achieved from seating?
3. What are the critical measurements?
- Seat Width: This is the widest point that the chair needs to accommodate. This may not be the hips – you should also consider trochanter width, ischial width, and trunk width.
- Seat Depth: The seat depth should be approximately 1 inch shorter than leg length. This can be calculated by measuring from the back of the buttock to the popliteal fossa.
- Seat to Floor or Footplate Height: To establish this, measure the distance from the popliteal fossa to the heel.
- Footrest Angle and Footrest Width: These measurements are based on how the feet should be supported according to plantar/dorsiflexion or inversion/eversion.
- Back Height and Angle: The back height is measured from the seat of the chair to the required chair back height, including allowance for supporting the head. Also note the optimum back angle.
- Armrest Height: The height of the armrest is critical in ensuring good posture. When taking measurements, measure the height for each arm separately in case of any differentiation.
