Hi Denny,

The fitbit and Apple monitoring you mention is an accelerometer,
attached to body limbs. They detect how much the patient moves in the
night in order to evaluate whether the patients paralysis is normal
during sleep AND whether the patients eyes open when they are in normal
sleep paralysis. These functions are controlled in a part of the brain
just above the brain stem, and an abnormal correlation often indicates
the patients need for B6. Note that serum B6 in the blood is useless-the
cells have to be examined directly because it's what's on the inside of
the cell that counts! Video and sound perform a similar function and
additionally the sound can monitor breathing to see if breathing
actually stops during sleep!

I ordered a 32 GB SD card for my cell phone and plan to take some
overnight video (with sound) soon.

Regards and ty for the info!
