Terminal latency index formula
latency, comparison of median and ulnar nerve sensory conduction, and comparison of fourth finger median-ulnar peak latency3. Terminal la-tency index (TLI) and residual latency (RL), cal-culated from distal motor latency, distal distance and proximal motor conduction velocities, are electrophysiological parameters used to identify Terminal latency index was used to compare the distal segment (distal to the wrist) with the intermediate segment (wrist to elbow).

Terminal latency index (TLI) was used to compare the wrist-to-thenar muscle segment with the elbow-to-wrist conduction velocity. Modified F ratio (MFR) was used to compare the spinal cord-to-elbow segment latency with that of the wrist-to-thenar muscle segment.
Background: The terminal latency index (TLI) is a calculated value that adjusts the distal motor latency for the terminal distance and the proximal motor nerve The calculation of TLI is explained in the material and methods-section on page 21. It was shown that the mean median nerve terminal latency index (TLI) with as distal motor latency (DML), terminal latency index.

Terminal latency index (TLI) was used to compare the wrist-to-thenar muscle segment with the elbow-to-wrist conduction velocity. Modified F ratio (MFR) was used to compare the spinal cord-to-elbow segment latency with that of the wrist-to-thenar muscle segment. The utility of terminal latency index (TLI) as an electrophysiological marker for MAG‐CIDP has been debated. In this study we confirmed its diagnostic usefulness and evaluated TLI threshold values for motor nerves investigated in routine nerve conduction studies. Sensitivity values of electrophysiological findings were as follows: median distal sensory latency (mDSL) 91.5%, fourth finger median-ul- nar sensory (M4-U4) latency difference 91.5%, mTLI 90.1%, median sensory nerve conduction velocity (mSNCV) 87.4%, and median motor dis- tal latency (mMDL) 68.6%. If we look at the tail when the machine is idle, say the 99.9%-ile latency, every terminal gets into the range where the additional latency ought to be perceptible, according to studies on user interaction.
