450 steps while asleep

[MarcTH]

My fitbit keeps registering steps while asleep, but I don't sleep walk, and nothing show up in the dashboard.  I have muscular spasticity. Could the spasms be registering as steps taken?

Which sleep sensitivity setting are you using: normal (which is the default) or sensitive? 450 steps sound like a lot of hand moves.

I’m in the opposite situation: I don’t get any steps during the night, even though I know for a fact I’m taking trips (from 1 to 3) to the bathroom. They show up as spikes on my HR graph, but don’t register as steps. Apparently, the trip is so short it doesn’t exceed the threshold for consecutive steps before steps are registered.

Mine registers every step to the bathroom. And it could be spasticity, which is what I am trying to determine.
