低频脉冲电流通过毫针刺激腧穴，具有调整人体功能、肌肉张力、加强止痛、镇静、促进血循环等作用。由于脉冲电流的波形、频率不同，其作用不同。频率快的叫密波（高频)，一般在50-100次/秒，频率慢的叫疏波（低频)，一般在2-5次/秒。

The low frequency pulsation of the stimulator would stimulate the point via the inserted filiform needle so as to affect the physiological function of the body, relieve the muscular spasm and pain, induce sedation and promote the blood circulation. As the pulsation varies in frequency and wave pattern, the actions of the pulses may be different. The high frequency pulse 50-100/sec is known as dense wave, the low frequency pulse 2-5/sec termed as rarefaction wave.

密波段

对感觉神经和运动神经产生抑制作用。常用于止痛、镇静、缓解肌肉和血管痉挛，针刺麻醉等。

Dense Wave

It may induce an inhibitory effect on the sensory nerve and motor nerve, commonly used for sedation and pain relief, relaxation of muscles and vessels spasm, acupuncture analgesia, etc.

疏波

刺激作用较强，能引起肌肉收缩，提高肌肉韧带的张力。对感觉和运动神经的抑制发生较迟。常用于治疗痿症、肌肉、关节、韧带、肌腱的损伤等。

Rarefaction Wave

It provides stronger stimulation to the points via the needles, thus causing contraction of muscle and the increment of the tension of muscles and ligaments. It induces a retarded inhibitory effect on the sensory and motor nerves. This kind of wave pattern is suitable for paralysis, injury of muscles, joints, ligaments, and muscular tendons, etc.医.学 全,在.线,提供www.med126.com

疏密波

是疏波、密波自动交替出现的一种波形。交替持续的时间约各1.5秒，能克服单一波形易产生适应的缺点。能促进代谢、气血循环，改善组织营养，消炎性水肿。常用于止痛，如扭挫伤、关节周围炎、气血运行障碍、坐骨神经痛、面瘫、肌无力、局部冻伤等。

Rarefaction-Dense Wave

It provides an alternation of rarefaction wave and dense wave, each wave lasting for one and a half second. This pattern has the advantage of avoiding sensory adaptation to the electro-stimulation which may occur in the treatment with single wave pattern, being good for the promotion of metabolism and the flow of Qi and blood, improving the nutrition of tissues and relieving the inflammatory edema. It is commonly used for pain, sprain and contusion, peripheral arthritis, disturbance of Qi and blood circulation, sciatica, facial paralysis, myasthenia, local frozen bite.

断续波

是有节律地时断时续自动出现的一种疏波。断时，在1.5秒时间内无脉冲电输出，续时，是密波连续工作1.5秒。此波不易产生适应，能提高肌肉组织的兴奋性，对横纹肌有良好的刺激收缩作用。常用于治疗痿症、瘫痪等。

Intermittent Wave

A regular intermittent rarefaction wave, it is an alternation of one and a half second stimulation in rarefaction wave and one and a half second on stimulation. This kind of wave may increase the excitability of muscular tissue and have a fine stimulative and contractive effect on the striated muscle. It is commonly used for muscular weakness and atrophy, paralysis, etc.

锯齿波

是脉冲波幅按锯齿形自动改变的起伏波，每分钟16-25次，其频率接近人体的呼吸规律，适用于刺激膈神经（相对于天鼎穴部)作人工电动呼吸，抢救呼吸衰竭，故又称呼吸波。并有提高神经肌肉兴奋性，调整经络的功能，改善气血循环等作用。

Sawtooth Wave

It is a kind of fluctation wave in sawtooth form, the frequency ranging from 16-25/min which is close to human's respiration, therefore also known as respiratory wave. It is used for stimulating the phrenic nerve, (Tianding LI 17) artificial electric breathing and respiratory failure. It also has the actions of raising the excitability of nerves and muscles, regulating the meridians and collaterals, improving the flow of Qi and blood.
