When RLN function recovers, discrepancies between EMG and VC movement have been reported in clinical and experimental studies. The present study was conducted to clarify the actual relationship between EMG and VC movement measured by ACC during nerve recovery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>EMG obtained by continuous nerve monitoring (C\u2010IONM) was compared with ACC during traction injury to the RLN, and throughout 40\u2010min nerve recovery. A three\u2010axis linear accelerometer probe was attached to the VC, and ACC data were registered as described. Traction damage was applied to the RLN until there was a 70% amplitude decrease from baseline EMG, or until loss of signal (LOS), that is, EMG values \u2264100\u2009\u03bcV.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010two RLN from 16 immature pigs were studied. Correlation between EMG and ACC were calculated during nerve injury and nerve recovery. The mean correlations were for the 70% and LOS group from start to end of traction: 0.82 (\u00b10.17) and 0.87 (\u00b10.17), respectively. Corresponding correlation coefficients during 40\u2010min recovery was 0.50 (\u00b10.48) in the 70% group and 0.53 (\u00b10.33) in the LOS group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>There is a high correlation between EMG and VC movement during nerve injury, and a moderate correlation during early nerve recovery.
