Gait analysis in children affected by myelomeningocele: Comparison of the various levels of lesion

The aim of this study was to utilise the gait analysis (GA) methodology to characterise the walking act in children with different levels of myelomeningocele. To this end, we analysed 30 children (mean age 11±3 years, still able to walk without ortheses) grouped according to the site of their neurological lesion (localised from L4 down to S5); ten healthy children (mean age 9±2 years) were also analysed for comparison. Of the many kinematic and kinetic parameters provided by GA, we focused on those providing a good correlation with the level of lesion. In particular, the following parameters are presented and discussed: angle of flexion at the knee joint at the moment of contact of the foot with the ground, knee joint flexion-extension range of motion, flexion of the hip at the beginning of the stride, anterior pelvic tilt, range of rotation of the pelvis in the horizontal plane and ankle joint power. The higher the level of the neurological lesion, the more these parameters of gait were found to deviate from those measured in the control group. This study emphasises the relationship that exists between the site (level) of the neurological lesion and the individual aspects of the functional limitation associated with it.
