We were, in fact, talking about having her wear some kind of wrist
bracelet.  However, there are complications.  One of them is her own
willingness.  I cannot express to you just how difficult it has been
to get her to do so much as wear underpants.  She is highly sensitive
to 'touch' on her skin.  We fought for years and years, almost minute
by minute in battles with her, over things like this.  Even today,
getting her to keep something on will be _very_ difficult.

There are other possibilities.
I assume you have considered CCTV, a camera and monitors.
A camera gives a new possibility, in this digital age,
I think one can do some analysis of the picture, for example
'falling over' could be detected perhaps, with some frame by frame processing.
Never programmed that, but I did do motion detection, and for sure frequency of
motion can be detected.
It is said that Microsoft is coming out soon with a new version of the Xbox
or one of it's variants (dunno), that has a camera that can detect gestures...
There must be some game developer API available...
Now I am just thinking aloud... could be some direction to look,
the vibration sensor or 'angle' (vertical versus horizontal, and speed of position
change) could be one of those 3 axis acceleration sensors, some people here (not me)
have extensive experience with those.

Yes, even 1D accelerometer would be enough to detect impact
(falling). But perhaps she is just jumping around for fun. So,
accelerometer could be part of the sensor, but not only one. However,
false positive might not be so bad, the OP might want to know when she
is having fun anyway.
