Summary
Wheelchair cushion covers protect internal components from damage. Rigidity of covers was tested and found not to significantly impact cushion performance, meaning the
Area of Science:
- Rehabilitation Engineering
- Biomedical Engineering
- Materials Science
Background:
- Wheelchair cushions require protective covers to prevent wear and contamination of load-distributing elements.
- Concerns exist that rigid cushion covers may negatively affect pressure distribution due to the 'hammock' effect.
Purpose of the Study:
- To quantify the impact of wheelchair cushion covers on load-distributing properties.
- To determine if the 'hammock' effect significantly impairs cushion performance.
Main Methods:
- Measurements of cushion deformation were taken.
- Seating pressures were recorded using a standard Department of Health wheelchair cushion.
- Various types of covers were tested to assess impairment.
Main Results:
- The 'hammock' effect, where rigid covers potentially alter cushion properties, was investigated.
- Data indicated that the influence of the cover's rigidity on cushion performance is negligible.
Conclusions:
- The 'hammock' effect from wheelchair cushion covers can be disregarded for practical applications.
- Protective covers do not significantly compromise the load-distributing capabilities of standard wheelchair cushions.
