Capture of the multimodal signals after the delivery of a single stimulus with the punctured needle electrode (left) and esophageal electrodes symmetrical to level rib 1 and 40Â mm spacing (right). Due to directed TEPNS, similar Pdi values are achieved compared with needle electrode stimulation, but with significantly higher bilateral acceleration values
