  • Title: Effect of body-scaled information on reaching in children with hemiplegic cerebral palsy: a pilot study.
    Author: Huang HH, Ellis TD, Wagenaar RC, Fetters L.
    Journal: Pediatr Phys Ther; 2014; 26(1):28-37. PubMed ID: 24356315.
    Abstract:
    PURPOSE: This study examined body-scaled information that specifies the reach patterns of children with hemiplegic cerebral palsy and children with typical development. METHODS: Nine children with hemiplegic cerebral palsy (3-5 years) and 9 age-matched children with typical development participated in the study. They were required to reach and grasp 10 different pairs of cubes. Reach data were coded as either a 1-handed reach or a 2-handed reach. Dimensionless ratios were calculated by dividing the cube size by the maximal aperture between the index finger and thumb. A critical ratio was used to establish the shift from a 1-handed to an exclusive 2-handed reach. RESULTS: The critical ratio was not significantly different for either preferred or nonpreferred arms within and between groups. All children used an exclusive 2-handed reach at a similar dimensionless ratio. CONCLUSION: Our study provides evidence of the "fit" between environment (cube size) and the individual's capabilities (finger aperture) for reaching for both groups.
