Abstract
Various basic qualitative and quantitative methods for the evaluation of sensorimotor functions after Traumatic Brain Injury (TBI) are introduced and discussed. Methodological aspects are illustrated by a single case follow-up study of a child after severe TBI (age 11; 712;1 yrs; 6, 8 and 12 month post TBI) in comparison to an age-matched healthy control group (N=16). The evaluation consisted of neurological investigation, Barthel-Index, Terver Numeric Score for Functional Assessment, Rappaport Disability Rating Scale (modified version), a coordination-test for children (KTK), a pilot-tested Motor Function Score, quantitative evaluation of spatiotemporal gait parameters on a walkway and on a treadmill, and the kinematic assessment of hand motor functions. Quantitative movement analyses revealed two general types of motor disorder: Slowing of movements and compensatory motor strategies. Averaged z-scores showed deficits, which were pronounced in fine motor skills (hand movements: 1.86, gait: 1.3). During follow-up, a strong improvement rate during the first (-0.48 z-scores) and nearly no improvement rate (-0.03 z-scores) during the second time interval was seen. Clinical scores and developmental tests were not able to document the whole restitutional course, whereas motor tests with special emphasis on functional aspects and the quantitative movement assessment seemed to be suitable methods. We conclude that a sufficient evaluation of sensorimotor functions after TBI in childhood needs an increase in procedural uniformity on onehand and the combination of various qualitative and quantitative methods on the other hand. To connect both claims, further research is necessary.
