I don't know of anything like that, but maybe there is a plugin for it.

However, I do know the '[ mark contains the start position where you last made a change. So, you could do something like this:

function! JumpIfChanged(move)
let movement=a:move " initialize to passed-in command
if line("'[") == line(".")
let movement = "`[".movement " jump to start of change first
endif
return movement
endfun

nnoremap <expr> j JumpIfChanged('j')
nnoremap <expr> k JumpIfChanged('k')
