Abstract
OBJECTIVE: The main purpose of this study was to measure the peak acceleration of the upper limb (UL) during reaching, and to calculate correlations between peak acceleration data and functional test results in children with cerebral palsy (CP). METHODS: We recruited 15 children with CP (8 boys and 7 girls) and measured peak acceleration and function as revealed by the Jebsen Taylor Hand Function Test (JTHF), the Quality of Upper Extremity Skills Test (QUEST), the Box and Blocks Test (BBT), and the ABILHAND-Kids questionnaire. We calculated correlations between peak acceleration data and scores on the functional tests. RESULTS: The peak acceleration of the more-affected UL was significantly higher than that of the less-affected UL (p< 0.05). The peak acceleration data were positively correlated with JTHFT scores. On the other hand, the peak acceleration data were negatively correlated with QUEST, BBT, and ABILHAND-Kids scores. The test-retest reliability of the peak acceleration was excellent, with an intra-class correlation coefficient (ICC) 0.87-0.98. CONCLUSIONS: Peak acceleration data correlated with UL functional test results; as this proved to be reliable, the tri-axial accelerometer is a clinically useful assessment tool for evaluating UL movement. Therefore, our results suggest that measurement of acceleration using a tri-axial accelerometer is appropriate when clinicians quantify UL movement during therapeutic rehabilitation in clinical settings.
