External noninvasive peripheral nerve stimulation (EN-PNS) is a neuromodulation technique in which a low-frequency electrical stimulation is applied via a ball-shaped electrode that is placed directly onto the skin. ⋯ Patients reported EN-PNS to provide ongoing benefit at long-term follow-up. Further prospective investigations are justified.

Diagnosis and treatment of pain in plexopathy, radiculopathy, peripheral neuropathy and phantom limb pain. Evidence and recommendations from the Italian Consensus Conference on Pain on Neurorehabilitation.
Pain may affect all aspects of social life and reduce the quality of life. Neuropathic pain (NP) is common in patients affected by plexopathy, radiculopathy, mononeuropathy, peripheral neuropathy. Phantom limb pain (PLP) is a painful sensation that is common after amputation, and its pathophysiological mechanisms involve changes in the peripheral and central nervous system. ⋯ Data on the functional outcome and impact of pain on neurorehabilitation outcome in these conditions are lacking. In most cases, a multidisciplinary approach is recommended to offer a better outcome and reduce side effects. High quality studies are requested to address the unmet needs in this field.

Symptoms described in previous studies indicate that electrical injury can cause longstanding injuries to the neurosensory nerves. The aim of the present case series was to objectively assess the profile of neurosensory dysfunction in electricians in relation to high voltage or low voltage electrical injury and the "no-let-go phenomenon". ⋯ Neurosensory injury can be objectively assessed after an electrical injury by using QST with thermal perception thresholds. The findings are consistent with injuries to small nerve fibres. In the clinical setting thermal perception threshold is therefore recommended, in addition to tests of tactile gnosis and manual dexterity (Purdue Pegboard).

Inhibition of Somatosensory Evoked Potentials During Different Modalities of Spinal Cord Stimulation: A Case Report.
Although the number of patients with chronic neuropathic pain treated by spinal cord stimulation (SCS) is continuously increasing, its analgesic mechanism remains to be elucidated. Previous studies have demonstrated that classical SCS (low stimulation frequency evoking paresthesia) inhibits the somatosensory evoked potentials (SEPs). ⋯ All the tested SCS modalities are able to inhibit SEPs and thus the lemniscal system. In particular, both paresthesia and paresthesia free SCS affect SEPs in the same manner. The presence of this inhibitory effect during paresthesia free modalities suggests that it is independent from the generation of action potentials, with a probable mechanism acting at the stimulation site. Further studies investigating the relationship between the inhibition of the lemniscal system and the analgesic effect of the SCS are, therefore, warranted.

To investigate the incidence and risk factors of neuralgia after limb-salvage surgery for pelvic tumors with focus on the reconstruction methods. ⋯ The incidence of post-operative neuralgia was 8.3 % in this study cohort. The LLVBS technique could increase the risk of post-operative neuralgia.
