Reliability and Applicability of the Bayley Scale of Infant Development-II for Children With Cerebral Palsy

Abstract

ObjectiveTo obtain reliability and applicability of the Korean version Bayley Scale of Infant Development-II (BSID-II) in evaluating the developmental status of children with cerebral palsy (CP).MethodsThe inter-rater reliability of BSID-II scores from 68 children with CP (46 boys and 22 girls; mean age, 32.54±16.76 months; age range, 4 to 78 months) was evaluated by 10 pediatric occupational therapists. Patients were classified in several ways according to age group, typology, and the severity of motor impairment by the level of the Gross Motor Function Classification System (GMFCS). The measures were performed by video analysis, and the results of intraclass correlation (ICC) were obtained for each of the above classifications. To evaluate the clinical applicability of BSID-II for CP, its correlation with the Gross Motor Function Measure (GMFM), which has been known as the standard motor assessment for CP, was investigated.ResultsICC was 0.99 for the Mental scale and 0.98 for the Motor scale in all subjects. The values of ICC ranged from 0.92 to 0.99 for each age group, 0.93 to 0.99 for each typology, and 0.99 to 1.00 for each GMFCS level. A strong positive correlation was found between the BSID-II Motor raw score and the GMFM total score (r=0.84, p<0.001), and a moderate correlation was observed between the BSID-II Mental raw score and the GMFM total score (r=0.65, p<0.001).ConclusionThe Korean version of BSID-II is a reliable tool to measure the functional status of children with CP. The raw scores of BSID-II showed a great correlation with GMFM, indicating validity of this measure for children with CP on clinical basis.

iMOVE: Intensive Mobility training with Variability and Error compared to conventional rehabilitation for young children with cerebral palsy: the protocol for a single blind randomized controlled trial

“…Eligible participants will meet the following criteria: 12–36 months of age, diagnosis of CP or suspected CP (motor percentile rank less than the 10th percentile on the Bayley Scales of Infant Development [ 44 , 45 ], and a neurological sign associated with CP, such as spasticity), the ability to initiate pulling to stand at a surface as indicated by a score of 1 on the Gross Motor Function Measure (GMFM) item 52 [ 46 ], and the cognitive ability to follow one-step commands. Participants will be ineligible for the trial if they demonstrate any of the following: secondary orthopedic, neuromuscular or cardiovascular condition unrelated to CP, general muscle hypotonia without other neurological signs associated with CP, independent walking ability as indicated by a score of 3 on GMFM item 69, or history of surgery or injury to the lower extremities in the past 6 months.…”

Effect of Functional Progressive Resistance Exercise on Lower Extremity Structure, Muscle Tone, Dynamic Balance and Functional Ability in Children with Spastic Cerebral Palsy

“…The gross motor function measure (GMFM) is a five-level classification system that appears to be valid in assessing the child's current motor functions, including laying/rolling, sitting, crawling/kneeling, standing and walking/running/jumping and is thought to have prognostic potential, i.e., early classification of a child could help determine long-term motor function [35]. The reliability ICC ranged from 0.92 to 0.99 for all dimensions and total scores [36].…”

The Validity of the Bayley-III and DDST-II in Preterm Infants With Neurodevelopmental Impairment: A Pilot Study

“…In the DDST-II and Bayley-III, medical personnel objectively observe the infants for the given criteria; these tests have the advantage of being able to determine quantified and age-corrected scores [ 8 9 10 ]. Due to their ability to evaluate the developmental status of infant patients in general (e.g., language, motor, cognition, and sociality), the DDST-II and Bayley-III are widely used for early developmental screening and developmental impairment diagnosis [ 11 12 13 ]. The DDST-II is intended to screen for developmental delays, and numerous studies have confirmed its validity and reliability in infants [ 4 14 15 ].…”
