Why do they have Wikipedia reference-linktennis elbow? Do they play tennis? or its it pain the the region of the proximal radioulnar joint. Perhaps if we can find the cause here that might shed better light on the best treatment. Are they doing anything particularly wristy, Do they have poor proximal shoulder control that causes an over-activity in the forearm extensors? I would start to look for these contributory factors.

I agree with the unloading principal of taping to facilitate reduction in pain while things 'heal' and the mechanics of the movement are addressed. 8o
