Ce. Buckon et al., DEVELOPMENTAL SKILLS OF CHILDREN WITH SPASTIC DIPLEGIA - FUNCTIONAL AND QUALITATIVE CHANGES AFTER SELECTIVE DORSAL RHIZOTOMY, Archives of physical medicine and rehabilitation, 78(9), 1997, pp. 946-951
Objective: This study examined changes in muscle tone, passive range o
f motion, stability, and mobility in developmental skills at 6 months
and 1 year after selective dorsal rhizotomy (SDR). Design: Prospective
outcome study of a consecutive sample. Setting: Private children's ho
spital. Patients: Twenty-six children with spastic diplegia: 13 indepe
ndent and 13 dependent ambulators (assistive devices). Results: A decr
ease in spasticity was seen at 6 months after SDR, with no further dec
rease at 1 year. Increases in passive range of motion of the hip and a
nkle were seen at 6 months after SDR. The ability to assume and mainta
in developmental positions with improved alignment and stability was s
een more frequently at 6 months after SDR, whereas an improvement in t
he ability to perform transitional movements was seen more frequently
at 1 year after SDR. Conclusion: SDR decreases spasticity and increase
s lower extremity range of motion in children with spastic diplegia an
d appears to be associated with the ability to assume a greater variet
y of developmental positions with improved alignment, thus greater sta
bility. Improvements in the ability to perform difficult transitional
movements at 1 year after SDR are most likely the result of the combin
ed effect of maturation, SDR, and intensive therapeutic intervention.
