ABSTRACT
Objective: to investigate the effect of spring gravity bar on knee joint
angle during gait in children with spastic diplegia.Method: thirty-six
children of both sexes (aged 7-10 years) with diplegic cerebral palsy were
enrolled in this study. They were randomly assigned into two groups of
equal number: the control and study groups. Evaluation was held before
and after 3 successive months of treatment using two dimension of gait
tracker video analysis to evaluate knee joint angle during gait cycles. Both
groups had received the conventional physical therapy program for one
hour / day three sessions per week. The study group additionally received
gait training on a spring gravity bar while the control group received the
classical gait training program. Results: A statistical significant
improvement in both groups was noted when comparing the mean value
of all measured variables before and after treatment (p≤ .05). there were
significant differences between the control and study groups with respect
to all measured variables which favored the study group when comparing
the post-treatment outcomes (p≤.05). Conclusion: Adding spring gravity
bar to gait training program had a beneficial effect in modulating knee
joint excursion in children with spastic diplegia.
