ZB meaning in Electronics ?

Zero balancing is a type of manual therapy devised by American osteopathic doctor Frederick "Fritz" Smith in the 1970s. Drawing from principles of osteopathy, Chinese medicine and Structural Integration, Smith proposed that the energy field within the human body could be affected by manual manipulations, so bringing health benefits. The practice teaches that currents of energy are stored within the human skeleton, and that these affect both physical and mental wellbeing.

According to an article in Science-Based Medicine, zero balancing is pseudoscientific. Article writer and lawyer Jann Bellamy places zero balancing among many vitalism-based practices that exist within the "cornucopia of quackery" of massage therapy. Bellamy writes that in the United States of America the public are inadequately protected from such practices because of the lack of independent oversight; instead regulation is carried out within a "closed loop" system by massage-focused organizations.
