Measuring impairment and functional limitations in children with cerebral palsy.

Conclusion. The disablement model is a valuable theoretical tool that can be used to organise assessments in CP and to explain how they are related. PMID: 21529123 [PubMed - as supplied by publisher] (Source: Disability and Rehabilitation)

The GDI-Kinetic: A new index for quantifying kinetic deviations from normal gait

This article introduces a new index, the GDI-Kinetic; a direct analog of the GDI based on joint kinetics rather than kinematics. The method consists of: (1) identifying “features” of the raw gait kinetic data using singular value decomposition, (2) identifying a subset of features that account for a large percentage of the information in the raw gait kinetic data, (3) expressing the raw data from a group of typically developing children as a linear combination of these features, (4) expressing a subject's raw data as a linear combination of these features, (5) calculating the magnitude of the difference between the subject and the mean of the control, and (6) scaling and transforming the difference, in order to provide a simple, and statistically well-behaved, measure. Linear combinati...

Pelvic kinematics and their relationship to gait type in hemiplegic cerebral palsy

Abstract: While there is general clinical consensus that children with Unilateral Spastic Cerebral Palsy (USCP) walk with an increased anterior pelvic tilt and the affected hemipelvis retracted, there is less agreement to observations in the coronal plane. Furthermore, the relationship of 3D pelvic kinematic parameters to the Winters, Gage and Hicks (WGH) hemiplegic gait classification has not been reported in the literature. Valid 3-D kinematic gait data were obtained in a representative population of 91 children with hemiplegia (56M, mean age 10.8yrs, age range 5–18yrs; WGH classification Type I n=32, II n=5, III n=7, IV n=9, unclassified n=38). Deviations of symmetry and range of movement from our normative data set (n=48; 26F; mean age 9.9yrs; age range 5–18yrs) for mean tilt, tilt...

We appreciate the interest expressed in our article, which investigated late deformities occurring after the transfer of flexor carpi ulnaris to extensor carpi radialis brevis in children with cerebral palsy. (Source: The Journal of Hand Surgery)

Wrist Tendon Transfers in Cerebral Palsy

The article by Patterson et al addresses deformities after wrist tendon transfer in patients with cerebral palsy (CP). They propose that failure of scar to stretch during rapid growth contributes to the development of a wrist extension deformity after flexor carpi ulnaris to extensor carpi radialis brevis transfer.
