In reply to Roberttaylor:
My mother has RA so is always asking me to extend the trekking poles she has, even if it isn't stuck as they can get. But some people might treat them as walking sticks and leave them as they are initially adjusted? I would expect a gift should look a bit nicer, so perhaps a cork handled version and one of the T handle shapes (never used those myself). Flick locks would be easier but I find the Black Diamond ones to be tricky, so perhaps Leki ones are better? I was amazed to see all the different rubber feet that they make for these now and more and more people are using them in the street when they come to the Lakes, even indoors!
Personally, I think the twist off camera screw handles and a wooden cap are the nicest but I haven't seen any for a while.
What about this as an idea but from a cheaper brand (or keep the receipt):

PS: if she decides she likes it, get some black reflective tape off ebay and put it around the pole, she will never notice...
