Figure 6.

Effect of previous peripheral nerve stimulation on reflex modulation. A, An example of the reflex responses (thick lines) in the flexor muscle when a PES at the right brachial plexus was applied (bottom panel) and was not (top panel). The thin lines demonstrate the waveforms without PTB. B, The reflex responses in both muscles in PES condition. Other notations are the same as in Figure 5. The asterisks express a significant difference between the force fields (**p < 0.01). Note that even when PES was applied, the modulation of reflex responses according to the cued force fields remained clear.
