I have my brother's old wooden crutches but i see everyone using aluminum and i have the option to get aluminum ones. Is there any reason why they'd be better then my wooden ones?
Aluminum's are lighter and adjust more easily. To set the length on woodies, have have to twist off the wing nuts, position the lower end into the rods and replace and tighten the bolts. Aluminum's are adjusted merely by pressing the lock pins.
Aluminum are lighter..........And I guess after a day of using Wooden Crutches...you can get really tired because of the exra weight your lugging around.
Aluminum might be lighter. As long as the crutches are in good shape and they are appropriately sized for you I say use what you've got.
