    Developmental limb apraxia in deaf children : an objective assessment
    (2001) Kinsella, Angela; Ogilvy, Dale
    This study determines the presence of developmental limb apraxia in deaf signing children and in an oral hearing-impaired child who presents with oral apraxia. The VICON 370 Motion Analysis System was adapted to objecitvely assess the presence of this disorder and to illustrate differences in patterns of movement between the experimental and control subjects.The execution of motor performance of praxic functioning was analysed on a continuum of complexity across signs, gestures and meaningless movement sequence. Qualitative measures of kinematic abnormalities, spatial parapraxias, temporal qualities, quantitative elbow joint angles, resultant tractories of elbow position and wrist joint centre were obtained.
