Changes in gluteal pressure and center of force during sitting in children with cerebral palsy

Area of Science:

• Biomedical Engineering
• Rehabilitation Science
• Pediatric Physical Therapy

Background:

• Children with cerebral palsy (CP) often experience challenges with posture and mobility.
• Understanding sitting pressure distribution is crucial for preventing secondary complications like pressure sores and scoliosis.

Purpose of the Study:

• To quantify gluteal pressure and center of force (COF) during sitting in children with CP.
• To compare these parameters between children with CP and typically developing controls.

Main Methods:

• Utilized the TekScan system to measure peak gluteal pressure and COF.
• Included five children with CP and five typically developing controls.
• Measurements were taken while participants sat unsupported on a therapeutic table for one minute.

Main Results:

• Children with CP demonstrated significantly higher peak gluteal pressure compared to controls.
• Center of force (COF) values were also significantly elevated in children with CP.
• These findings indicate altered pressure distribution during sitting in this population.

Conclusions:

• The study underscores the importance of managing hip pressure distribution in children with CP.
• Rehabilitation strategies should focus on achieving even pressure distribution.
• Facilitating a forward shift of the center of force (COF) is recommended for improved sitting posture and function.
