A present was then utilized at a frequency of 30 Hz, which sufferers described as an inside buzzing sound. They then continued with their present coaching routine and accomplished duties to enhance motion and grip energy.

What had been the outcomes? An article in Naturopathy by Moritz et al. (2024) report that:

Seventy-two p.c of contributors confirmed enhancements higher than the minimally vital distinction standards for each energy and useful domains.
