Reflex stiffness of the flexing human index finger was studied using sinusoidal movements at 3–16 Hz. The Nyquist stiffness diagram indicates the presence of a ‘presonance’ at around 4 Hz, its ‘C’ shape after correction for the mechanical properties of the relaxed finger is consistent with the involvement of a stretch reflex in its generation. This contention was supported by the presence of negative friction around 4 Hz and the disappearance of the modulation of the stiffness curve after… CONTINUE READING
