Abstract

Background: Death by electrocaution in the water is not always indicate a specific phenomenon. Electric shock can cause damage to limb muscles, so hystopathologic examination is necessary. This study aimed to determine how strong the correlation between the electric current through water conduction with the damage of Wistar rat’s gastrocnemius muscle in the form hypercontraction points number of muscle fibers that occur. Methods: This was an experimental study with post test only control group design, using Wistar rats as research samples. Thirty Wistar rats whose have inclusion and exclusion criterias was adapted for one week and then divided into five groups, each groups had six Wistar rats. One control group was not given the exposure of electric current and the four other groups were given exposure of electric current-rise, ranging from 10-30 mA, 31-60 mA, 61-90 mA and 91-120 mA. All of the samples was examined by counting the number of hypercontraction points of muscle fibers that occur. Hypothesis test uses Spearman test by SPSS for Windows 11.5. Result: Spearman test indicates p = 0.000 or there was a significant correlation between the exposure of electric current with the number of hypercontraction points of muscle fibers. The value had a very strong positive correlation (r = 0.852). Conclusion: The greater the exposure of electrical currents is given, the number of hypercontraction points of muscle fibers that occur is getting greater too. The number of hypercontraction points of muscle fibers can describe the damage of skeletal muscles are due to the electrical injuries. Key words: electric current, muscle hypercontraction, water conduction
