Standing is a common modality used in the management of children with developmental disabilities. The purpose of this article is to examine the scientific basis for standing programs, with specific emphasis on the known effects of weight bearing on bone development. Guidelines for the use of standing programs are presented, and the supporting rationale is(More)
Three therapists measured tibiofibular torsion and thigh-foot angle (TFA) goniometrically in 17 normal subjects, aged three to 24 years. Tibiofibular torsion was also measured using computed tomography (CT). Differences between testers for the goniometric measures were analyzed using a nonparametric analysis of variance. Wilcoxon's rank sum test was used to(More)
The reliability of five lower-extremity goniometric measurements of 20 patients with moderate to severe hypertonicity was assessed by three pediatric physical therapists. The measurements were repeated on five of the children within one week. Intra-rater variation was less than inter-rater variation for all measurements, but variations of 10 to 15 degrees(More)
The aim of this investigation was to quantify the differences in torque steadiness and variability of the muscular control in children with cerebral palsy (CP) and typically developing (TD) children. Fifteen children with CP (age=14.2±0.7 years) that had a Gross Motor Function Classification System (GMFCS) score of I-III and 15 age and gender matched TD(More)
BACKGROUND Upright sitting is one of the first developmental motor milestones achieved by infants, and sitting postural sway provides a window into the developing motor control system. A variety of posture sway measures can be used, but the optimal measures for infant development have not been identified. METHODS We have collected sitting postural sway(More)
By quantifying the information entropy of postural sway data, the complexity of the postural movement of different populations can be assessed, giving insight into pathologic motor control functioning. In this study, developmental delay of motor control function in infants was assessed by analysis of sitting postural sway data acquired from force plate(More)
The purpose of this investigation was to evaluate the work performed on the center of mass by the legs of children with cerebral palsy. 10 children that were diagnosed as having cerebral palsy with spastic diplegia (Age=9.1+/-2 years), and 10 healthy children with no walking disabilities participated (Age=9.4+/-2 years). We collected individual leg ground(More)
The authors present nine clinical assessment procedures designed to detect factors contributing to transverse-plane structural and joint alignment abnormality in children with neuromotor dysfunction. Where applicable, each assessment is accompanied by a discussion of the normal features of pediatric lower-extremity torsional and rotational alignment;(More)
The purpose of this study was to examine intratester and test-retest reliability using a hand-held dynamometer for the measurement of isometric muscle strength in 28 healthy children and children with Duchenne muscular dystrophy. The Dystrophic Group consisted of 14 children diagnosed with Duchenne muscular dystrophy, and the Healthy Group consisted of 14(More)
Infant sitting postural sway provides a window into motor development at an early age. The approximate entropy, a measure of randomness, in the postural sway was used to assess developmental delay, as occurs in cerebral palsy. Parameters used for the calculation of approximate entropy were investigated, and approximate entropy of postural sway in early(More)
