Latency time (Command)
Total latency time in command condition

This variable is only available in MARS and in Clinical Core.

Latency time in the command condition is the sum total of all inter-digit, pre- and post-first hand latencies during the command condition. Latency time is captured during the digital Clock Drawing Test (dCDT) using digital pen technology. See the digital pen device category description for more information.

Participants are asked to “draw the face of a clock with all of the numbers and set the hands to 10 after 11.”

Latency time during the command condition is expressed in seconds.
