Heel wedges may influence standing posture but how and to what extent are
unknown. Thirty-two children with motor disorders -
16 with arthrogryposis
multiplex congenita (AMC) and 16 with cerebral palsy (CP) -
and 19 control
children underwent a three-dimensional motion analysis. Unassisted standing
during 20s with shoes only and with heel lifts of 10, 20 and 30mm heights was
recorded in a randomized order. The more weight-bearing limb or the right limb
was chosen for analysis. In both the AMC and CP groups, significant changes were
seen between various heel lifts in ankle, knee and pelvis, and in the control
group in the ankle only. Between orthosis and non-orthosis users significant
differences were seen between different heel lift conditions in ankle, knee and
trunk in the AMC group and in the ankle in the CP group. Pelvis position changed
toward less anterior tilt with increasing heel height, but led to increasing knee
flexion in most of the children, except for the AMC Non-Ort group. Children with AMC and CP represent different motor disorders, but the heel wedges had a similar
influence on pelvis, hip and knee positions in all children with CP and in the AMC orthosis users.
A challenge is to apply heel heights adequate to each
individual's orthopaedic and neurologic conditions to improve biomechanical alignment with respect to all body segments.
