Low frequency machines operate at frequencies below 20Hz only and make up the largest number of home use pivotal machines on the market. Companies who import these machines will often promote them as being the same as the scientifically proven machines, but fail to explain the differences. The reality is that low frequency pivotal machines do have some benefits, but not as many and would not produce as significant results as pivotal machines with full frequency range. Benefits of these machines include balance, blood circulation, lymphatic drainage, relaxation of muscles, and exercise recovery.
