First, the working principle of cervical vertebra massager
1, low-frequency pulse massage is the massage effect produced by electric frequency pulse when the electrode is in contact with the skin. Based on the low-frequency therapy principle of TENS pulse current, pulse current with low frequency (1000HZ), low current (100mA) and low voltage (100V) is applied to nerves or muscles to promote local circulation, improve muscle state and relieve acute and chronic pain.
Low-frequency pulse massage stimulates muscle contraction by controlling the frequency and band of low-frequency pulse current, and then relaxes muscles, so there will be a sense of numbness of current. Hot compress can improve the blood circulation of the neck, reduce the accumulation of lactic acid and relieve the tension and pain of the neck muscles.
2. Physical kneading massage combines the techniques of pushing, taking, softening, kneading and pressing in traditional Chinese medicine, and simulates different massage effects through the operation of massage head. Through the mechanical way combined with the meridian science of traditional Chinese medicine to imitate the human hand, all kinds of massage techniques are realistic and realize muscle relaxation. The more and more flexible massage heads, the more comfortable they will be.
Second, the precautions of cervical massager
1, choose different types of cervical massagers according to different massage functions. According to different massage parts, choose the corresponding massage head and install it on the massage instrument.
2, according to the need, choose the strong and weak position of the switch. When starting to use, you can turn the switch to the strong and weak position first. After a little massage, if there is no discomfort, you can adjust it to the strong and weak position.
3. After fasting, satiety, drinking and strenuous exercise, cervical massagers, especially strong stimulation massage, should be avoided, because this will further accelerate the blood flow rate, enhance the peristalsis of gastric smooth muscle, and produce discomfort such as nausea, vomiting, chest tightness and shortness of breath.
4. When operating, it is normal to feel the vibration of the arm when holding the massager. If you feel uncomfortable, you can wrap some soft things such as sponges to reduce the vibration of your arms.
5. The use time of cervical massager can generally reach 30 minutes. If you feel uncomfortable during or after massage, you should stop using it.
6. When using the cervical massager, you sweat a lot, and then massage with a towel, which is safe and effective.
7. In the process of using the cervical massager, if the vibrator does not move, the vibration is loose or the noise is too high, you should immediately turn off the switch, unplug the power plug, and carefully check and troubleshoot before using it.
After understanding the working principle of cervical massager, you can better choose the cervical massager that suits you. Generally speaking, the physical kneading cervical massager is more suitable for most people. Although the cervical massager is small, it is also an electrical appliance. Pay attention to the safety of electricity when using it.
