ABSTRACT
Cerebral palsy children have increased tendency to develop fractures later in life, for which low bone mineral density might be one of the factors. The aim of this study was to evaluate the bone mineral density in children with cerebral palsy and factors affecting it. A total of 82 diagnosed children with cerebral palsy were sampled by non-probability purposive sampling from the outpatient department of Armed Forces Institute of Rehabilitation Medicine. Bone mineral density (BMD), z-score was measured at lumbar spine with Dual Energy X Ray Absorptiometry (DEXA) at L1- L4 lumbar vertebra. Analysis was done using SPSS (Version 20). Statistical comparisons were made using independent sample t-test. Of the 82 children 37 (45.1%) were males and 45 (54.9%) females. The mean age for all the children was 5.6 + 2.34 years and mean BMDz- score was -2.12 + 0.67. There were statistically significant differences in BMDz score with respect to age groups, pattern of involvement and ambulation status (p0.05). The BMDz-scores were lower, especially in the quadriplegic and non-ambulant children. BMD if identified early and managed timely can prevent future fragility fracture risk and avoid delay in rehabilitation process.
