Abstract

The goal of the gastrocnemius-soleus complex (GSC) lengthenings in children with cerebral palsy (CP) is to achieve a plantigrade foot and normalize kinematics during gait. The study purpose was to evaluate the results of GSC lengthening for isolated equinus contracture in individuals with CP. It was hypothesized that GSC lengthenings would normalize passive ankle range of motion, kinematic, kinetic, and temporal spatial parameters. Gait data from 15 able-bodied participants from the laboratory normal database and passive range of motion, kinematic, kinetic, and temporal spatial gait parameters, and oxygen cost were collected and analyzed for 27 individuals with CP (36 limbs) with isolated equinus contracture who received GSC lengthenings. Data were compared between preoperative and postoperative assessments. Mean age at baseline was 11.4 years (+/-3.2 y). Mean time between surgery and postoperative gait analysis was 1.3 years (+/-0.3 y). Passive range of motion measurements were obtained. Kinematic and kinetic data for the hip, knee and ankle, and temporal spatial parameters were obtained from a representative gait trial preoperatively and postoperatively. Paired t tests (P<0.05) determined whether preoperative data differed fr...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
