Hand function in cerebral palsy: the effect of hip-flexion angle.

B R Seeger, D J Caudrey, N A O'Mara

    Developmental Medicine and Child Neurology
    |October 1, 1984

    Summary

    Increasing hip flexion in seating does not improve hand function for children with cerebral palsy and extensor spasticity. Mild increases in seat angle were found to be most comfortable.

    Area of Science:

    • Pediatric Rehabilitation
    • Neurology
    • Biomedical Engineering

    Background:

    • Cerebral palsy (CP) often involves extensor spasticity, impacting motor function.
    • Seating interventions aim to optimize posture and function in children with CP.
    • Current practices suggest specific hip flexion angles may benefit hand function.

    Purpose of the Study:

    • To investigate the effect of increased hip flexion angles on hand function in seated children with CP.
    • To determine if hip flexion beyond 90 degrees enhances hand function in this population.
    • To assess subject comfort at various hip flexion angles.

    Main Methods:

    • Objective measurement of hand function in children with CP and extensor spasticity.
    • Comparison of hand function across four distinct hip flexion angles.
    • Inclusion of both experimental and control groups for robust analysis.
    • Subjective reporting of comfort levels at different seating angles.

    Main Results:

    • No significant improvements in hand function were observed with increased hip flexion.
    • Hip flexion angles of 10 and 20 degrees above horizontal were least associated with discomfort.
    • The hypothesis that increased hip flexion improves hand function was not supported.

    Conclusions:

    • Contrary to existing beliefs, increasing hip flexion in seating does not enhance hand function for children with CP and extensor spasticity.
    • Seating adjustments should consider comfort, with mild angles (10-20 degrees) appearing most tolerable.
    • Further research may explore alternative interventions for improving hand function in this population.
