Mod to use mouse 4 and 5 as keybind?

I would absolutly love if there was a mod that made it possible to add mouse 4 and 5 as my run and sprint button but the game just doesn't let me and i have lost 5 total caracter in like the last month just because i keep hitting home button because any other key then alt for sprint (i use cap maj as my run button) just brake my hand so does a mod like that exist
