This is a list of walking aids in a Hospital: 'canadianas, muletas axilares, andarilho'.

I already translated 'canadianas' into crutches, so is there another term I could use for 'muletas axilares'? The only one that I know and also comes up on the internet is 'crutches'.

Thank you for your help!
