Darn foot injury from repetitive movement (2,3,3)

I believe the answer is:

to and fro

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

'from repetitive movement' is the definition.
I can't judge whether this definition defines the answer.

'darn foot injury' is the wordplay.
'injury' indicates anagramming the letters.
'darn'+'foot'='darnfoot'
'darnfoot' is an anagram of 'TO-AND-FRO'.

Can you help me to learn more?

(Other definitions for to and fro that I've seen before include "Shuttle's motion" , "Directions of oscillation" , "From place to place" , "both ways" , "This way and that, back and forth" .)
