MUSCLE STRENGTH TESTING IN CHILDREN: DEVELOPMENT AND EVALUATION OF A NEW MOTOR PERFORMANCE TEST
Authors: W. A. Van den Beld
Abstract: Most validity and reproducibility studies on instruments to test muscle strength have been done in adults. There is need for data from children, because such instruments are frequently used on children in clinical practice. Our study on the performance of muscle strength instruments in children aged 4 to 11 years showed that a new Motor Performance Test had the highest validity and highest reproducibility compared to hand-held dynamometry and the Jamar dynamometer. The child-friendly Motor Performance Test can improve the diagnostic procedure in children suspected of having myopathy and spare more children from painful muscle biopsy. Moreover, it is a suitable instrument for monitoring purposes in children.
