Actigraphy for Better Sleep?

Tuesday, January 5th, 2010

I previously questioned the efficacy of the Zeo "Personal Sleep Coach" and concluded that this device would be unlikely to provide their claimed sleep improvements.

Another method for monitoring sleep patterns is with the use of Actigraphy*. I seriously doubt that these movement-based devices can do any better:

At least the Zeo device uses an EEG-based sleep histogram for determining sleep state. How can the acitigraph tell the difference between someone just laying awake quietly versus deep sleep?

*This Wikipedia entry reads like an advertisement for one these devices!

Is the Zeo “Personal Sleep Coach” a Scam?

It's hard to believe that MedGadget covered the Zeo Personal Sleep Coach as if it were a real medical device.

At first the technology looks intriguing:

  • Softwave™ Sensor Technology (wireless)
  • Bedside Display
  • Web and Database Technology

So far so good. Then you get:

  • Personalized Sleep Coaching Program
  • SmartWake™ Alarm (optional)

RED FLAG!!!

and the Zeo 7 Steps to Sleep Fitness are:

  1. Evaluate your Sleep Fitness
  2. Relax your way to sleep
  3. Build your bedroom sanctuary
  4. Optimize your sleep schedule
  5. Adopt the Power Down Hour™
  6. Eat and drink smart for sleep
  7. Harmonize with your housemates

All for only $399 (with free shipping).

Now the fine print:

Zeo Personal Sleep Coach is neither a medical device nor a medical program and is not intended for the diagnosis or treatment of sleep disorders. If you suspect that you may have a sleep disorder, consult your physician.

Is this for real?  I guess I shouldn't be surprised -- No FDA approval.

I can believe that these sensors are capable of collecting EEG that could be used for sleep staging.  But even that hasn't been proven true. An abstract accepted  for presentation is interesting but is not validation. The technology here is the confidence part of the trick.

They claim to use the sleep histogram (personal sleep score or "ZQ") along with on-line analysis as a metric for determining if any of the  7 "Sleep Fitness" steps are actually helping.  Based on normal ranges of sleep stage percentages during the night these metrics may well tell you if a person slept "normally", but can ZQ changes really be attributed to some lifestyle alteration? Where's the clinical validation for this?

Also, the technology is supposed to:

find what could be a “natural awakening point” - when it could be a little easier to get out of bed in the morning.

It could, huh?

Anyone that would shell out money for a product like this probably has a real sleep disorder and should see a medical professional for evaluation.

Most sleep disorders are caused by apnea events anyway. A real ambulatory polysomnography (PSG) system (e.g. the Somté) includes EEG, EOG, and a full complement of breathing parameters (airflows, pressures, and SaO2).

To me anyway, the Zeo device and program will help very few people and appears to be another direct-to-consumer rip-off.
