Ambulation in patients with myelomeningocele: a multivariate statistical analysis.
Factors determining ambulation in 163 patients with myelomeningocele were studied by a multivariate statistical method. Neurological dysfunction unrelated to the plaque was analyzed by magnetic resonance imaging. There were no ambulators at the thoracic or L1-L2 level. At the L3 level, 54% ambulated, and at the L4 level, 67% ambulated. Eighty percent were ambulators at L5 and all at the sacral level. Below L1-L2, one-half of the nonambulators had neurological deficiencies caused by syringohydromyelia or Chiari malformations preventing ambulation. Severe scoliosis was closely, age moderately, and hip flexion contracture slightly related to the inability of the other nonambulators to walk, while pelvic obliquity, hip dislocation, or knee flexion contracture was not.
