The Measurement of the High Speed Terminal Extension Power in the Knee Joint

The terminal extension power of the knee is very important for its stability. Now we can evaluate it in isotonic contraction or low speed isokinetic motion. But we have never been able to measure the strength in the high speed isokinetic motion. High speed measurement is more reasonable to the sports activity. So we used a new machine (MYORET made by kawasaki Juko) which can measure the high speed terminal extension power using so called “passive mode” and evaluated 7 objects (14 knees).
