Position Type (X _maxForce )

X,Y,Z position in mm where max force occured

Mean Force (\(\bar {F}\))

Mean Force reading in Newtons along X,Y,Z axes

Mean Force Magnitude Value

Maximum Force (F X _max )

Maximum force along X,Y,Z axes

Maximum force magnitude

Force Slope (\(\hat {F}\))

Slope of magnitude force across repetitions for

flexion /extension
