Cycling and walking balance are related. The tests could help in relating the two, and possibly contribute to understanding. They may indicate other underlying medical conditions.
They both rely on balance, but as the search you posted throws up the mechanisms used to retain balance are very different between cycling and walking.
The medical profession already has numerous tests for balance - before implementing another it would be wise to assess what's missing from existing ones and asking whether a proposed new one plug those holes.

How to test an individual's (current) propensity to have falls of one kind or another? The obvious answer is to acquire a history of performance of the balancing acts, counting the incidents where the balancing failed. Can an artificial test of any real utility be devised to simulate such balancing acts and any propensity to fail at the balancing? Maybe - but they would never be as good as the history of the actual balancing acts performed in the full circs in which such balancing is done.
So here's another complication in such assessments: what of the real-world circs in which such balancing acts are done add or detract from the risk of not-balancing when one needs to? In cycling the answer is that there are many such real world peripheral circs. They could never be included in a simulator test that didn't tend to become "actually cycling about in the real world".
And this history would need to be analysed to identify the rate of head-bangs when un-balancing occurred; and the percentage of serious head bangs; and those in which a cycling helmet either reduced the impact or alternatively contributed to any injuries (such as those from a rotational jerk to the neck when a helmet catches on something).
If such history and a sufficiently fine-grained analysis of it could be made (which seems unlikely but possible*) I suppose one might derive some sort of probability figure for varying cycling circs and the individual cycling in them that might be the basis of deciding to wear a cycling helmet or not. What probability figure should be the watershed?
If such figures are derived and result in the buying and wearing of a cycling helmet, what other everyday activities involving the possibility of falls should have histories recorded and decisions made on the analysis? How much history is needed? As individual behaviours and capabilities change over time, what makes such a collected history redundant or irrelevant?

In short, such calculations of risk can never ne anything much better than a wild guess (AKA an intimation or, more bluntly, irrational** fear). How much easier to choose the cycling helmet and its wearing based on fashion, peer pressure, adverts and other factors? A lot easier. Which is why it's what helmet buyers actually do.
* Some can make an informal history of their conduct whilst needing to balance in some way, coming to the conclusion that "I'm very good at it, rarely falling" or "I fall over all the time, everywhere" and various in between balancing-skills. That could be a legit basis of an ad-hoc analysis and decision resulting in the use (or no use) of a cycling helmet based on the probability of a future fall/head-bang. Having road-cycled for 65 years and fallen rarely, with no head-bangs involved, I use that history and its "analysis" to decide not to wear a cycling helmet unless I can foresee a very dangerous cycling circ in my next planned ride. (Although in fact I'd just not ride)
