From: Infrared neural stimulation markedly enhances nerve functionality assessment during nerve monitoring
INS can be integrated in to existing clinical IONM systems while maintaining performance. (a) Normalized CMAP amplitudes resulting from ES in baseline, healthy, partial transection, and complete transection conditions. Black dashed line represents the amplitude damage threshold (50% decrease). (b) Normalized CMAP amplitudes resulting from INS in baseline, healthy, partial transection, and complete transection conditions. (c) Sensitivity and specificity for the amplitude-based IONM approach to transection injuries. (d) Normalized CMAP amplitudes resulting from ES in baseline, healthy, partial crush, and complete crush conditions. (e) Normalized CMAP amplitudes resulting from INS in baseline, healthy, partial crush, and complete crush conditions. (f) Sensitivity and specificity for the amplitude-based IONM approach to crush injuries. (g) Normalized CMAP amplitudes resulting from ES in baseline, healthy, partial stretch, and complete stretch conditions. (h) Normalized CMAP amplitudes resulting from INS in baseline, healthy, partial stretch, and complete stretch conditions. (i) Sensitivity and specificity for the amplitude-based IONM approach to stretch injuries. Specificity in all cases was calculated using the ‘Healthy’ category of responses. All data is normalized to the mean baseline values for each individual nerve. \(n = 4{ }\) nerves for all data sets (2 rats).
