Good spot to see how those vertigo therapy sessions are working out.

Those buttons were obviously used to slyly divert the patient's attention while she went about her dastardly deeds.

(Just hopping on the over-imagination bandwagon)

I suppose cribs could have been used for certain folks who just tended to roll around a lot and fall out of normal beds. Modern hospital beds do have low side bars.
If they were strapped in, they wouldn't really need the bars, and the bars don't seem like they would have stopped someone not strapped in from hopping out.

They likely used to go through quite a few toilets from being repeatedly jumped on until they started with the concrete. The sink is probably high enough to deter most jumping.

Vic Tanny Machine we called them, as he always had those in his tv commercials. He was the Jack LaLanne of the era.

Ah, I love the smell of mimeographs in the mornng. Smells like...QUIZZES!
