[Late effects of low-voltage electricity accidents. Rotator cuff tendinitis, hearing loss and neuropsychological dysfunction].

This article describes the symptomatology of three patients following electrical accidents. The flow of the current was from hand to hand, voltage was 220/380 V, and duration was at least a few seconds for all patients. The development of symptoms was the same, and may be explained as a thermal effect of electricity on the tissue. Initially the patients experienced transient confusion, followed by stiff muscles after 1 to 3 days, and then pain in the muscle attachments and joints close to path of the current. This pain increased slowly during the first two weeks. Recovery was gradual, but often incomplete. The case notes showed that electrical accidents may be followed by chronic rotator cuff tendinitis. The clinical examination also revealed a hearing loss at about 2,000 Hz and above 4,000 Hz. The neuropsychological testing indicated a diffuse impaired function in only one patient.
