Representative knee angle of a patellar tendon reflex test.

<p>Time 0 is the time the reflex hammer struck the patellar tendon. Reflex amplitude is measured as the offset of knee angle from the original position.</p

Comparison of mean values of experimental and theoretical maximum tapping velocities (±SD).

Mean values of patellar tendon reflex amplitudes according to tapping angle (± standard error).

<p>The reflex amplitude increased gradually with the increment of tapping angle. ^* denotes statistical significance difference compared to tapping angle of 15°. ^# denotes statistical significance difference compared to tapping angle of 30°. ^$ denotes statistical significance difference compared to tapping angle of 45°. ^¤ denotes statistical significance difference compared to tapping angle of 60°. ^¢ denotes statistical significance difference compared to tapping angle of 75°. ^¥ denotes statistical significance difference compared to tapping angle of 90°. Symbols (^¤, ^¥) in bold indicates statistical significance difference at <i>P</i><0.01, symbols not in bold indicates statistical significance difference at <i>P</i><0.001.</p
