Sensitivity (red/light) and probability (blue/dark) for cross-correlation based conduction velocity analysis (CVA). This novel methodology for reflex detection is based on evaluation of muscle fiber conduction velocity (CV) and maximal cross-correlation estimated from surface electromyography. Sensitivity and specificity is presented for both the tibialis anterior (TA) and soleus (SOL) muscles. The black cross indicates the identified thresholds entailing an equally weighted joint value for sensitivity and specificity of 0.96 and 0.91 for TA and SOL respectively.
