When comparing style 1 versus style 2 needling, we found significant differences in mean displacement and rotation amplitude (p<0.001 and p<0.001, respectively), but not displacement or rotation frequency (p=0.10 and p=0.76, respectively) (figure 3).
The maximum rotation frequency was 14500 rpm.
This has the added benefit of suppressing the influence of any rotation-induced sources of systematic noise that manifest at the fundamental turntable rotation frequency (see Fig. 3).
An operating rotation frequency of 325 MHz has been chosen.
The mean rotation of the femoral component was 7.6° external rotation.
Also the flux increased with rotation frequency up to an optimal frequency of 20 Hz.
The rotation frequency does not appear to follow the E2 behaviour of the Taylor Melcher model, suggesting that this may be a different kind of flow instability.
At the same time, one needs to pay attention to the muscle force in the feet, to the right speed and pedal rotation frequency.
Peaks corresponding to the fundamental turntable rotation frequency and higher-order harmonics can be resolved clearly, whereas the background noise level has not increased.
