Thank you Bonette for all of your very useful ideas and recommendations.
We have wondered about such "travel" crutches in the past. It would be really convenient to have a pair, especially if you traveling with a wheelchair or walker as well etc.. My father's concern has always been the stability.... He is a big man - over 6' 1" and he has recently gained quite a bit a weight... and he pounds his crutches! So any crutch that is not really sturdy is a concern, and we are starting to wonder if a crutch with a weight limit of 250 lbs might be a little risky.
My Dad has been scanning the web and it seems like there are more options for crutches then when we first bought his 4 years ago. He is finding some brands I am not familiar with that have shock absorption in the crutch itself (!), and he was questioning whether the ergonomic hand grips were necessary...... He's also had a rough time with his Walk Easy cuffs, which get stretched out from falls and regular use and clearly need to be replaced much more frequently. Wonder if the Federman cuffs are a much more sturdy construction.
So thanks for posts everyone. I would love to hear more stories about the pros/cons of the crutches you use and what you have learned, and what is your ideal.... And how often you replace your crutches (and how you decide when to...)?
