Reliability of isokinetic evaluation in passive mode for knee flexors and extensors in healthy children

BACKGROUND: The isokinetic dynamometer has been considered the gold-standard measurement of muscle performance. However, the reliability for the passive mode in children has not been reported to date. OBJECTIVES: The purpose was to evaluate the reliability of the isokinetic dynamometer in passive mode in children. METHOD: Twenty-one healthy children (ten girls, eleven boys), aged 5 to 12 years (age: 8.5±2.2 years), were evaluated using an isokinetic dynamometer. Each participant was tested twice with a one-week interval and performed five consecutive cycles of knee extension and f...
