Validity and responsiveness of the test of athletes with knee injuries: the new criterion based functional performance test instrument.
The purpose of this study was to evaluate the validity and responsiveness of the new criterion-based test instrument test for athletes with knee-injuries (TAK) which has been evaluated for reliability in an earlier study. Thirty-five subjects between 18 and 50 years were included in the study. They were all anterior cruciate ligament (ACL)-reconstructed and operated with hamstrings graft. ⋯ The total points for TAK/patients' assessment and TAK/physiotherapist's assessment showed large effect size (1.08 and 1.03), respectively. IKDC/total score and SF-36 scale physical functioning showed moderate effect size (0.79 and 0.41), respectively. The result of this study showed that the TAK is a reliable instrument with a large effect size for changes over time, indicating that the TAK is a very sensitive functional test instrument assessing the ACL-reconstructed patients during the rehabilitation period.
