In reply to ben b:
> I should clarify "balance" - they are good for balance in the sense of not falling over despite rough ground. They aren't good for the intrinsic sense of balance..... Presumably because you can "get away with more" and are less reliant on your intrinsic sense of balance.

It can be argued that whilst a healthy individual is growing (and maturing their sense of balance), frequent pole use ( i.e. a more generous base of support) will shield the developing neuromusculoskeletal system from the perturbations of balance which would otherwise be experienced over uneven ground.
Take the poles away, and that pole user may not cope as well as someone similar who has frequently gone over the same ground without poles. Their intrinsic balance is therefore impoverished.
This is not the scenario played out by most hillgoing pole users.
The majority of hillgoers are urban adult 'plodders'. Discounting the use of poles for offloading the joints of those carrying excessive weight, with some of those we meet -poles clacking as they walk along the easy, level ground- it's sometimes difficult to see why they need to use them. Sure, you could tell them 'you don't need this level of support, you're impoverishing your intrinsic balance capabilities', but are they?
If, because of consumer choice, they see poles as necessary for getting out, then probably this 'getting out', this increased activity will maintain their balance above that of an otherwise sedentary person without poles.
Then there are the loose category of more 'sporty' looking hillgoers who appear able to move, no better than unremarkably, over broken ground. Some of them may have poles. They don't appear to move fluidly.
Within this group, there will be the 'all the gear, no idea' people who buy kit such as poles to convince themselves and to show off to others how seriously they take their mountaineering.
I guess it can be argued that some of them might enhance their intrinsic balance capacity if they ditched the poles. But we'll never know, as they are pole users.
Then there are another subgroup of pole users, myself among them. Generally a bit older. probably with one or two age related joint wear and tear issues, but differing from the plodders in their ease of rapid mobility over complex terrain. This group can only do this because they use poles frequently.
'Ah, but they're they are only balancing in the sense of not falling over despite rough ground. Their poles aren't good for the intrinsic sense of balance ' ...
I disagree.
My intrinsic balance would be at a much lower level nowadays, were it not for pole use, something I only came to in my fifties, and then, because I thought it would be nice to walk, from my house, over all the British 3000's. This choice to use poles was not just because of load carrying. It was because I have joints in my foot that don't move well. Had I not taken poles, I would have negotiated some ground more cautiously. In using poles day in, day out, combined with the fitness gained, I began to move quicker and more efficiently than I had done in my 20's, 30's and 40's. Poles extended the sort of terrain I was able to move rapidly and efficiently over. I began to choose sightlines to bomb over which I would never have attempted before at that pace, even unladen.
In doing so I enhanced my intrinsic balance capabilities. Nowadays, take away the poles, and I can still tackle more complex ground than I did before their use. Slower than with the poles, but still..
So, quite categorically I can state that poles do not always impoverish your intrinsic balance.
Regarding your suggestion for a comparative study, people who use poles do so for a variety of reasons. Some of them may use them because they have e.g. a functional joint problem. If they have a functional joint problem, then their capacity for standing on one leg may be affected.
