Ambulatory outcome of children with myelomeningocele: effect of lower-extremity muscle strength.
The relationship between patterns of strength and mobility was studied in 291 children with myelomeningocele, graded as community ambulators, partial (household) ambulators and nonambulators. Iliopsoas strength was found to be the best predictor of ambulation, with the quadriceps, anterior tibialis and glutei also contributing significantly. Grade 0 to 3 iliopsoas strength was always associated with partial or complete reliance on a wheelchair. No patient with grade 4 to 5 iliopsoas and quadriceps function relied completely on wheelchairs and the majority were community ambulators. Grade 4 to 5 gluteal and anterior tibialis function was associated with community ambulation, without aids or braces. Deterioration in mobility was most common in those with strong iliopsoas/quadriceps and grade 0 to 3 gluteus medius, and was not age-related.
