  • the pediatric temporal Spatial Deviation index quantifying gait impairment for children with cerebral palsy
    Developmental Medicine & Child Neurology, 2019
    Co-Authors: Joanne Y Zhou, Katelyn Cahillrowley, Kevin S Zhang, Evan Lowe, Jessica Rose
    Abstract:

    AIM To develop an easily-administered metric to quantify gait impairment in children and to assess its use in children with cerebral palsy (CP). METHOD The Pediatric Temporal-Spatial Deviation Index (TDI) was developed from gait data collected from 75 typically developing children (37 males, 38 females; mean age 9y 4mo; interquartile range [IQR] 8-10y) and 17 children diagnosed with spastic CP (nine males, eight females; mean age 9y 9mo; IQR 9-11y), in Gross Motor Function Classification System (GMFCS) levels I to III, aged 7 to 11 years. Children walked on a pressure-sensitive mat. Children with CP also completed 3D gait analysis. The Kaiser-Meyer-Olkin test of sampling adequacy was used for temporal-Spatial feature selection. Principal components obtained from temporal-Spatial gait parameters quantified Deviation from typically developing gait. Deviation was normalized to a Pediatric TDI score mean (standard Deviation [SD]) of 100 (10). The Pediatric TDI for children with CP was compared to 3D motion capture-based Gait Deviation Index (GDI). RESULTS The Pediatric TDI was significantly lower for children with CP compared to typically developing children (p<0.001), correlated with average GDI (r=0.610, p=0.009), and demonstrated sensitivity (0.78) and specificity (0.88) to gait function, assessed with GDI. INTERPRETATION The Pediatric TDI is an easily administered, revealing gait metric that can be used in children with CP in pediatric clinics and for research. Detection of gait abnormalities in the clinic can expedite diagnosis and treatment. What this paper adds The Pediatric Temporal-Spatial Deviation Index (TDI) is a single-score index of gait Deviation, based on nine parameters. The Pediatric TDI was more revealing than single temporal-Spatial gait parameters. The Pediatric TDI is quick and simple to administer in the clinic.

    Abstract:

    This research aims to develop a gait index for use in the pediatric clinic as well as research, that quantifies gait Deviation in 18-22 month-old children: the Toddle Temporal-Spatial Deviation Index (Toddle TDI). 81 preterm children (≤32 weeks) with very-low-birth-weights (≤1500g) and 42 full-term TD children aged 18-22 months, adjusted for prematurity, walked on a pressure-sensitive mat. Preterm children were administered the Bayley Scales of Infant Development-3rd Edition (BSID-III). Principle component analysis of TD children's temporal-Spatial gait parameters quantified raw gait Deviation from typical, normalized to an average(standard Deviation) Toddle TDI score of 100(10), and calculated for all participants. The Toddle TDI was significantly lower for preterm versus TD children (86 vs. 100, p=0.003), and lower in preterm children with <85 vs. ≥85 BSID-III motor composite scores (66 vs. 89, p=0.004). The Toddle TDI, which by design plateaus at typical average (BSID-III gross motor 8-12), correlated with BSID-III gross motor (r=0.60, p<0.001) and not fine motor (r=0.08, p=0.65) in preterm children with gross motor scores ≤8, suggesting sensitivity to gross motor development. The Toddle TDI demonstrated sensitivity and specificity to gross motor function in very-low-birth-weight preterm children aged 18-22 months, and has been potential as an easily-administered, revealing clinical gait metric.

  • research on Spatial Deviation analysis model of land use change
    Economic Geography, 2005
    Co-Authors: Zhang Xinchang
    Abstract:

    The Deviation analysis of Spatial-temporal structure is based on GIS overlay. At present, the method in common use to describe Deviation of expansion in Spatial structure makes use of comparative analysis to study difference of various classification of land-use in Spatial position. Although this method can draw the outline of Spatial structure characteristic of land-use with object and brief advantages, its changed speed is not comparative in the strict sense because divided Spatial units are not equal land areas. Thus the method above is improved in the paper by creatively importing the changing intensity index by average of year that the comparative new index can describe Deviation of land-use Spatial-temporal structure. Changing intensity index means that land-use changed area of a certain Spatial unit is percentage of overall land area in different a certain period of research. In order to compare intensity or trend of urban land-use change in different period of research, changing intensity index in each Spatial unit by average of year that has been calculated is a standard processing course is for its changing speed by average of year in land area of each Spatial unit. The changing intensity index is comparative. Thus we can make a through research for land-use classification and obtain Deviation situations of Spatial-temporal structure for different land classification. The result will benefit the planning management of urban land-use of developed districts in China in the future.
