Effects of prolonged repetitive stimulation of median, ulnar and peroneal nerves.

abstract：:We measured the peak voltage induced in a sensing loop by a Magstim 200 magnetic stimulator. Coil output varied little for repeated stimulation at the same intensity over a wide range of coil output. In contrast, the first stimulus immediately after a change in intensity was of larger amplitude and showed greater vari...
