Osteopenia and Cerebral Palsy
In the second study, Shaw et al. measured the bone mineral density in the lumbar spine of 9 children who were non-ambulatory with cerebral palsy, ages 2 to 13 years. Subjects were compared to an age and sex-matched control group of children without disabilities. All of the children with cerebral palsy exhibited a severe reduction in bone mineral density.
In the third study, Lin and Henderson found reduced muscle mass, bone mineral content, and bone mineral density in the affected limb of 19 children with spastic hemiplegia. Lean muscle mass was reduced by 15 percent and bone mineral density by 6 percent in the affected limb of children with cerebral palsy compared to the unaffected limb. The researchers noted that further research is needed to determine if these reductions can be altered through weight-bearing activities.
