Zulu 'I farm emmer that's ground to give support for elderly' (6,5)

I believe the answer is:

zimmer frame

I'm a little stuck... Click here to teach me more about this clue!

'give support for elderly' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'zulu i farm emmer that's ground' is the wordplay.
'zulu' becomes 'Z' (phonetic alphabet: alpha, bravo, charlie etc.).
'that's ground' is an anagram indicator ('grind' the letters into a new form).
'farm'+'emmer'='farmemmer'
'farmemmer' anagrammed gives 'mmerframe'.
'z'+'i'+'mmerframe'='ZIMMER FRAME'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for zimmer frame that I've seen before include "Aid to walking" , "Walker's aid" .)

I've seen this clue in The Daily Mail.
