Effect of Long Term Orthotic Intervention on Gross Motor Function in Children with Spastic Cerebral Palsy
Oxygen consumption in walking test pre and post hamstring lengthening. Results or Clinical Course: 11.5 percent of our population presented with knee hyperextension after hamstring lengthening. Regression analysis showed that the main predictor of hyperextension after hamstring lengthening is knee flexion at midstance (mean of 23.9 degrees) Analysis of oxygen consumption data did not reveal any significant changes in children with hyperextended knees vs. nonhyperextended knees. Conclusions: Incidence of knee hyperextension after hamstring lengthening in our population is 11.5 percent. Pre operative knee flexion at midstance was correlated with the presence of knee hyperextension post surgery. Interestingly, there was no significant change in gait efficiency as measured by oxygen consumption in hyperextended knees vs non hyper extended knees.
