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 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)
OBJECTIVES To determine the reliability of linear and nonlinear tools, including intrasession and intersession reliability, when used to analyze the center of pressure (COP) time series during the development of infant sitting postural control. DESIGN Longitudinal study. SETTING University hospital laboratory. PARTICIPANTS Typically developing infants(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)
OBJECTIVE To examine if body weight supported treadmill training (BWSTT) improves the regularity of stepping kinematics in children with cerebral palsy (CP). METHODS Twelve children with CP who had Gross Motor Function Classification Scores that ranged from II-IV participated in 12 weeks of body weight supported treadmill training that was performed 2(More)
PURPOSE To examine the feasibility of using lower body positive pressure supported (LBPPS) treadmill training to improve the walking abilities, balance and lower extremity strength of children with cerebral palsy (CP). METHODS Nine children with CP (GMFCS II-IV) participated in LBPPS treadmill training 2 days per week for 6 weeks. Pre and post training(More)
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)
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)
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)
The purpose of this study was to determine the level of interobserver and test-retest reliability of the Milani-Comparetti Motor Development Screening Test. Sixty healthy children, aged 1 through 16 months, were videotaped during administration of the Milani-Comparetti test. Four pediatric physical therapists independently viewed each videotape and scored(More)
