From: Infrared neural stimulation markedly enhances nerve functionality assessment during nerve monitoring
Electrical and infrared neural stimulation evoke consistent amplitudes over time as measured by clinical IONM system. (a) Probability distribution of normalized amplitudes evoked in undamaged nerves resulting from ES (teal) and INS (red) using a clinical IONM system. Grayed region represents amplitude values that fall below the damage threshold (50% decrease in amplitude). (b) Statistical analysis of amplitude variance and false positive rates. (c) Time course of normalized amplitude values over two hours produced by ES and INS. All values normalized to the mean at \(t{ } = { }0\;{\text{min}}\). Linear fitting performed on all data for ES (\(R^{2} = 0.131\)) and INS (\(R^{2} = 0.026\)). \(n = 12\) nerves for all distribution graphs [a–b; 6 rats total]; \(n = 3\) nerves and rats for time course plot in (c).
