Some chiropractors study this science. If I remember correctly, there was a lot of advancement in this back before antibiotics came out. Then it got shoved aside. In the past decade or two, it’s been reemerging. Has some interesting data….but someone would need to know what they’re doing and have the calibrated equipment. It is actually VERY complex.
