Correction versus bedding: wheelchair pressure distribution measurements in children with cerebral palsy
Insights
Pressure mapping in wheelchairs helps identify pain causes and optimize seating for children with severe cerebral palsy (GMFCS IV-V). This technology aids in balancing posture correction with comfort, improving wheelchair use and technical aid adaptation.
Area of Science:
- Neuroscience
- Orthopedics
- Rehabilitation Engineering
Background:
- Children with severe cerebral palsy (GMFCS Levels IV-V) often cannot walk, leading to prolonged wheelchair use.
- Spastic muscle contractions in these children can cause joint malpositions and scoliosis, complicating seating needs.
Purpose of the Study:
- To investigate the utility of pressure distribution measurement in optimizing wheelchair seating for children with severe cerebral palsy.
- To identify the causes of pain and discomfort experienced by children in wheelchairs.
Main Methods:
- Utilized a pressure distribution measuring mat to analyze seat pressure patterns in wheelchair users.
- Examined the effectiveness of pressure-reducing seats.
Main Results:
- Pressure mapping facilitates a balance between postural correction and comfortable seating.
- Identified specific pressure patterns linked to pain and discomfort.
- Effectiveness of pressure-reducing seats was evaluated.
Conclusions:
- Pressure mapping offers a more objective method than clinical examination for diagnosing seating-related issues.
- This technology aids in optimizing seating positions and adapting assistive devices for children with neuro-orthopedic conditions.
- Facilitates easier detection of problems and pain origins in wheelchair-bound children.
Purpose:
Most children with cerebral palsy classification Levels IV and V in the Gross Motor Function Classification System (GMFCS) are unable to walk and, therefore, spend almost all day in a sitting position in their wheelchairs. As a result of the spastic muscle contraction, malpositions of joints or a scoliosis develop, which require a decision to be made on whether to correct the posture or simply find the best soft bedding position.
Methods:
The distribution of pressure on the seat while sitting in a wheelchair was measured with a pressure distribution measuring mat. The different distribution patterns were analyzed.
Results:
Pressure distribution measurement allows to find a compromise between posture correction and soft bedding. Additionally, pressure-reducing seats were examined on their effectiveness. We also focused our measurements and data analyses on recognizing the causes for pain. Sometimes, the origin of the problems and pain of children in wheelchairs is not clear.
Conclusions:
Using the above-mentioned measuring equipment, the causes of these problems can be detected much more easily than just by clinical examination. The pressure measuring mat can help to optimize the seating position for the spastically handicapped children and adapt technical aids. Examples demonstrate the most frequently occurring problems of these children in their wheelchairs which are typical for neuro-orthopedic diseases.
