Description
Clamping Forces
The force data were filtered post-hoc using a 4th order Butterworth filter. An appropriate cutoff frequency was determined by evaluating the spectral density of the data . To avoid the phase shifting associated with IIR digital filtering, force data were filtered first with a 2nd order Butterworth filter, then inverted, filtered again with the same 2nd order filter, and inverted back. A MATLAB program was written to extract the peak clamping force, average plateau force, rate of force application, total clamping time, and total time clamped starting from the peak force for Groups 1 and 2 .A second MATLAB program was written for Group 3 to extract the total cycling time and frequency of clamping.
