“…We showed that this risk group extends beyond just electricians, as only half of our patients were electricians. We have replicated the findings regarding abnormalities in temperature sensitivity from our previous study [ 16 ] and have extended these findings to include clinical measurements of nerve fiber function. These revealed a mixed picture suggesting that motor nerves, as well as different types of large- and small-diameter sensory nerves, in the upper or lower extremity were differently affected in different patients.…”

“…Participants can have a max score of 24, and a score of 12 or above indicates a presence of moderate to considerable symptoms. The HAVS is a validated questionnaire [ 10 , 16 ] that contains 10 items about hand symptoms with the scaled options of no, light, moderate and considerable. To be included, participants had to have a SLANSS score of ≥12 and report moderate or considerable symptoms on HAVS.…”

“…We have previously demonstrated reduced somatosensory abilities in people suffering an electrical accident: reduced hand thermal sensitivity to both heat and cold while vibration perception was within the normal range [ 1 ]. This suggests injury to the thinly myelinated and unmyelinated afferents responsible for the transmission of temperature alterations [ 15 , 16 ]. Here, we extended previous findings using several methods to test nerve fiber functionality in people reporting symptoms after suffering an electrical accident in the past two to six years.…”

Objective: Work related electrical accidents are prevalent and can cause persisting symptoms. We used clinical neurophysiological techniques to assess neurosensory function following electrical accidents and correlated test results with the patients’ symptoms. Methods: We studied 24 patients who reported persisting neurosensory symptoms following a workplace electrical accident. We assessed nerve function using quantitative sensory testing (QST), thermal roller testing, laser evoked potential (LEP), and electroneurography. The patients’ results were compared with previously established normative data. Results: Altogether, 67% of the patients showed at least one neurosensory impairment with a large heterogeneity in test results across patients. At a group level, we observed significant deviations in in QST, LEP, and sensory and motor neurography. Overall, we found a weak correlation between test results and self-reported symptoms. Conclusions: In a majority of patients with neurosensory symptoms after a workplace electrical accident, neurosensory testing confirmed the existence of an underlying impairment of the nervous system.

“…Peripheral polyneuropathy can appear after a high-voltage injury (10% of peripheral neuropathies following an electrical injury) [18] or lightning strike [24]. Furthermore, small fibre polyneuropathy has been reported either associated with high-or with low-voltage injury [25].…”

“…administered the cognitive tests and scales. In total, the psychological investigation, which also included an interview (Thomée and Jakobsson 2018), took 3-4 h. On the same day, the participants underwent a neurophysiological examination (2.5-3 h) conducted by a physiotherapist (Rådman et al 2016a). These two investigations alternated so that half of the participants started with the psychological examination and half with the neurophysiological investigations.…”

Purpose The purpose was to examine long-term consequences of exposure to electrical current passing through the body. We investigated (1) whether electricians after having experienced an electrical accident report more cognitive problems and lower mental wellbeing and (2) have objectively verifiable reduced cognitive function; and (3) which circumstances at the time of the accident affect long-term subjective cognitive function and mental wellbeing? Methods A survey of male electricians who had experienced electrical accidents (n = 510) and a clinical study in a subsample (n = 23) who reported residual health problems was carried out. Both groups were examined regarding subjective cognitive function (Euroquest-9) and mental wellbeing (Symptom Checklist-90 subscales). The clinical study included neuropsychological tests of memory, attention, spatial function, and premorbid intellectual capacity. A matched control group was retrieved from reference data. Results The survey participants reported more cognitive problems and lower mental wellbeing than referents. Of the examined circumstances, having experienced mortal fear at the time of the accident and health complaints, especially mental symptoms, for > 1 week after the accident were the most significant risk factors for later subjective cognitive problems and lower mental wellbeing. The only statistically significant difference in neuropsychological tests was better performance in part of the memory tests by the clinical study group compared to the control group. Conclusions The participants reported more cognitive problems and lower mental wellbeing than referents, but no long-term objective cognitive dysfunction was detected. Emotional response at the time of the accident and health complaints in the aftermath of the accident may constitute important indications for medical and psychological follow-ups.
