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

'poor treatment' is the definition.
(misuse is treating someone badly)

I don't understand the remainder of the clue.

(Other definitions for misuse that I've seen before include "Poor treatment" , "Application to a bad purpose" , "Wrongful employment" , "Ill-treatment" , "Employ or apply wrongly" .)

I've seen this clue in The Sun.
