“…These effects include increases in the discharge threshold of the Ia afferents and inhibition of Ia terminals (Hayward et al, 1986, Hultborn et al, 1987, Shinohara, 2005. Such vibration has been shown, in the ankle, to decrease the amplitude of H reflexes in both the stimulated and synergistic muscles (Curtis and Eccles, 1960, Hultborn et al, 1987, Shinohara, 2005. Such vibration exposure has been demonstrated to alter overall joint dynamics as well, with vibration of the ankle tendons, for example, altering center of pressure trajectories in standing sway after vibration exposure (Wierzbicka et al, 1998).…”
