OBJECTIVE To systematically review the efficacy of interventions to improve low bone mineral density (LBMD) in children and adolescents with cerebral palsy (CP). METHODS We performed a systematic search for published randomized, controlled trials (RCTs) and controlled clinical trials (CCTs) of children with CP (aged 0-20 years, all Gross Motor Function Classification System [GMFCS] levels) who received various medical and physical interventions for LBMD compared with no intervention or standard care. Study validity was evaluated by using the Physiotherapy Evidence Database (PEDro) scale. Standardized mean differences (SMDs) were calculated when data were sufficient. RESULTS Eight of 2034 articles met the inclusion criteria (6 RCTs, 2 CCTs). There were 3 trials of bisphosphonates, one of which (Henderson RC, Lark RK, Kecskemethy HH, Miller F, Harcke HT, Bachrach SJ. J Pediatr. 2002;141[5]:644-651) revealed a large and significant effect on BMD in 1 of 3 sites in the distal femur (SMD: 1.88 [95% confidence interval (CI): 0.52-3.24]). There were 3 trials of weight-bearing through varying approaches, one of which (Caulton JM, Ward KA, Alsop CW, Dunn G, Adams JE, Mughal MZ. Arch Dis Child. 2004;89[2]:131-135) showed a large and significant effect on the lumbar spine when increasing static standing time (SMD: 1.03 [95% CI: 0.21-1.85]). The administration of vitamin D and calcium produced a large, nonsignificant effect on BMD in the lumbar spine (Jekovec-Vrhovsek M, Kocijancic A, Prezelj J. Dev Med Child Neurol. 2000;42[6]:403-405) (SMD: 0.88 [95% CI: -0.07 to 1.84). Growth hormone combined with vitamin D and/or calcium resulted in effects comparable with vitamin D and/or calcium on BMD in the lumbar spine (Ali O, Shim M, Fowler E, et al. J Clin Endocrinol Metab. 2007;92[3]:932-937) (SMD 0 [95% CI: -1.24 to 1.24]). CONCLUSIONS Important effects on LBMD have been observed in small and diverse cohorts of children with CP. It is unclear whether small sample sizes or variable treatment responses account for nonsignificant findings. Additional large RCTs are needed of both physical and medical approaches.

D002547	Cerebral Palsy	A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR.

D015519	Bone Density	The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
