The aim of this study was to retrospectively analyze changes in age- and
sex-adjusted body mass index (BMI) in ambulatory children with cerebral palsy
(CP) who underwent selective dorsal rhizotomy (SDR). METHOD: Raw BMI, age- and
sex-adjusted BMI z-scores, weight classification status, energy expenditure, and
ambulation function were calculated before and after SDR at multiple post-SDR
time points: 6 to <24 months, 24 to <48 months, 48 to <72, and 72 to <96 months.
Linear mixed models were used to analyze changes in raw BMI, BMI z-scores, energy
expenditure, and ambulation function. RESULTS: Pre- and post-surgical data were
available for 363 children diagnosed with CP who underwent SDR (219 males, 144
females; mean age 6y [SD 2y 1mo]; mean BMI z-score 0.09 [SD 1.21]). Data from
additional post-surgical time points were collected on subsamples. Although raw
BMI significantly increased (p<0.01), these increases were consistent with
anticipated growth. BMI z-scores did not significantly change over the 10-year
study period. INTERPRETATION: Concerns of unhealthy weight gain following SDR are
not supported by this study. Further work examining possible risk factors for BMI
increase following SDR, as well as examining disparities in existing criteria for
patient selection, is merited.
