Abstract

PURPOSE: We are trying to develop the objective index, which represents the gait pathology of transverse plane in cerebral palsy for outcome assessment of surgical intervention.
MATERIALS AND METHODS
We evaluate 23 spastic hemiplegics with pre- and post-operative 3D gait analysis and 13 able-bodies. Mean pelvic rotation (MPR), maximum pelvic rotation (XPR), Mean hip rotation (MHP), Foot progression angle (FPA) in stance were extracted from the kinematic data and principal component analysis was used to make an index for transverse plane gait pathology, so-called transverse index (TI) .
RESULTS
Transverse index for able-bodies was 40+/-29. In spastic hemiplegics, transverse indices were 151+/-59 preoperatively, 68+/-44 postoperatively.
CONCLUSION
We present the index for transverse plane gait pathology by the way of multivariate study.
