Abstract
Background: Children with cerebral palsy suffer from deficits in balance,
motor control, and pelvic malalignment. Purpose: The purpose of this study
was to investigate the correlation between pelvic alignment, standing balance
and selective voluntary motor control in children with spastic diplegia.
Methods: One hundred children with spastic diplegia aged from five to eleven
years participated in this study. Their pelvic alignment (pelvic tilt, pelvic
rotation, and pelvic inclination), standing balance (overall, anteroposterior, and
mediolateral stability indices), and selective voluntary motor control were
evaluated using Formetric instrumentation system, Biodex system, and
Selective Control Assessment of the Lower Extremity scale respectively.
Results: The results showed a positive significant correlation between pelvic
tilt, overall and mediolateral stability indices. Also, there was a negative nonsignificant correlation between pelvic tilt and anteroposterior stability index,
negative non-significant correlation between pelvic rotation, overall and
anteroposterior stability indices, and positive non-significant correlation
between pelvic rotation and mediolateral stability index. Positive significant
correlation between pelvic inclination, overall, anteroposterior, and mediolateral
stability indices were found. Negative non-significant correlation between
pelvic tilt and pelvic inclination with selective voluntary motor control, and
negative significant correlation between pelvic rotation and selective voluntary
motor control were also found. Conclusion: pelvic malalignment affects
standing balance and selective voluntary motor control abilities in children with
spastic diplegia.
