Figure 6

A comparison of difference values of the impulse of joint acceleration attributed to individual torque between the pressed and struck touches across different torques for the shoulder, elbow and finger joints at each loudness level. The negative value indicates that the impulse at the pressed touch is smaller for the shoulder, and smaller for the elbow and finger compared with the struck case. Note that a result of the wrist joint was not shown due to no significant difference in the peak angular velocity between the two touches. * p < 0.05, ** p < 0.01. The error bars represent ± 1 SE.
