(4)Use Purpose and Eect by Frequency Range
Frequencies below 20 Hz are eective for chronic pain, knotted muscles and stiness, while frequencies over
100Hz ease sudden pain in the back or joints faster than low frequency. Medium frequency, which is a lot used
in the range of over 1000 Hz, penetrates deeply into skin and directly stimulate internal organs, which has an
eect on constipation, etc.
Although ultrasonic waves 1 MHz less than 1.0 W have a low lipolysis eect, they aect the depth of penetration
of current by being combined with low/medium frequencies and have a cartilage regeneration eect through
a thermal eect. The ultrasonic waves used in the EMS Body Massager of EtBu are less than 1.0 W, and do not
need separate power.
(5)Eective Use Method
For eective use, it is important to contact the correct parts with the pad (electrode). Appropriate intensity and
use times should be adjusted according to symptoms. Stimulating one part continuously for more than 30 minutes
and stimulating twice or more a day are not recommended.
Eects vary depending on the user’s muscle tension, and the necessary intensity of stimulation is dierent.
(6)Intensity
Strong intensity alone is not good. As it is important how deeply the frequency penetrates, you should adjust
it to the intensity that is suitable for you. Extremely high intensity can aggravate symptoms by stimulating
nerves such as muscle ligaments. In other words, intensity is subjective. You should adjust it to the level where
you feel comfortable or good.
The sense of current varies widely by individual. Therefore, there is no absolutely good designated intensity.
If you have problems with your senses or with the expression of opinions or had a disease that should be
considered, you must select the stimulation carefully according to condition or state. Humans’ sensory nerves
normally become insensitive after the prolonged use of electric stimulation due to an adaptation phenomenon.
Those who have repulsion to electric stimulation are recommended to receive it at a slightly weak level.
If you endure strong stimulation forcefully, it is not good as muscles are more tensed.
