Reliability of isokinetic strength measurement of the knee in typically developing children has yet been studied and seems to be good. Because in daily life activities strength of the hip- and ankle-joint muscles are also important, the investigators aim to study the reliability and validity of isokinetic strength measurements of the hip and ankle.
Intra-tester reliability of isokinetic strength measurements of the knee, hip and ankle in a Biodex System 4 device will be studied. Children will be assessed at different movement velocities using the test-positions as proposed by the manufacturer. Maximum peak torque will be established.
Children will also perform functional strength assessments and the relation with the results of isokinetic strength measurements will be analysed.
