Zeile 8: Zeile 8:
 Several cycles of movement should be included, but there is no study which analyses how many cycles is best. We recommend more than 3 cycles, others recomment a minimum of 5. The optimal number may depend on many issues, including the joint  and the amount of soft tissue artfeacts. Each user should experiment with his own measurement procedure. Several cycles of movement should be included, but there is no study which analyses how many cycles is best.
