Sleepwalking event characterization

Based on the data recorded for each sleep walking events I described them the following way:
  • Start time of event (clock time and since falling asleep)
  • Length of event
  • Length of time since the previous event in the same night
  • Event characteristics (binary format: did or did not do it):
    • 5 levels scale of actions
    • 11 levels scale of actions + repetitive behaviors
  • Heart rate
    • Average value for the night
    • Max value at time of event
  • Length of time since last drug taken
  • Sleep stage at time of event (provided by sleep tracking device)

  1. Wonderful blog.. (I can't get OpenId to work though?). Look forward to heart rate or heart rate variability data? Don't understand the complexity variables and/or 5 levels scale of actions 11 levels scale of actions + repetitive behaviors (will keep looking at the site though).

  2. Hi Chris,

    There is more about the complexity scores here:
    http://somnambuler.blogspot.com/2015/06/how-to-compare-sleewalking-activity.html
    The idea is to find a way to compare 2 events. The complexity score provides a qualitative assessment of each event while the heart rate provides a quantitative one.
    Heart rate data are available on each parameter looked at, usually graph B titled "average event heart rate increase".
    As for OpenID I am not familiar with that product. It could be that Google intentionally blocks that third party, this blog being part of Google.
