Answer

However, peroneal nerve stimulation may be better in some cases because of the following:

  • Duing clinical diagnostic testing, some patients can tolerate peroneal nerve stimulation but find posterior tibial nerve stimulation too uncomfortable.

  • The posterior tibial nerve may be difficult or impossible to stimulate adequately in some patients, because of adiposity at the ankle, casting, amputation, etc.

  • In some patients with peripheral neuropathy (which may tends to affect longer nerves more severely), peroneal nerve SEPs may be present whereas no posterior tibial nerve SEPs are identifiable.
