Yes.  Kentucky law requires that an employee be allowed a 10 minute paid rest break for each 4 hours worked. 

The rest break is in addition to the meal or lunch break, but, remember, the meal or lunch break need not be paid. 

That said, the question isn't as easy or as clear-cut as it may initially seem. A factory worker who is constantly on the production line with parts or components streaming constantly down the assembly line has to stay on the line and keep at it. An office worker, on the other hand, usually has great leeway to get up and leave his or her work space as needed or desired. Are these self-directed interruptions of work considered breaks? Hard to say they wouldn't be. On the other hand, they're not clear-cut and distinct 10 minute periods.
