The advantage of this instrument is that the therapist can determine the stimulation effect of each point by adjusting the strength of electricity as well as the pulse frequency. This means that both sedative and tonicizing effects can be achieved. These instruments can be used with needles too. This application is more frequently used than electrodes. The instrument is attached to the needle via clip adapters.
Electricity flows directly through the needle to the acupuncture point.
The effect is, in this case, more direct. The range of instruments can be differentiated through various criteria. The construction of the instrument is important. Electrically analogous instruments are simple instruments. The emitted electricity is logically subject to variations.
