Various treatment strategies including low level laser therapy (LLLT) are used to treat neck pain [6, 7]. The term Laser is an acronym for light amplification by stimulated emission of radiation-a form of photonic therapythat is defined by the following characteristics: collimation &#; it has little beam divergence over distance; convergence &#; the light waves are all in phase; and monochromicity &#; it has a single or narrow band of a particular wavelength of light [8]. Proponents of LLLT note laser devices are either high power or low power. High power laser devices, having a thermal effect, destroy tissue and are used during surgical procedures and for thermolysis. Low power laser devices have little to no thermal effects, have a stimulative effect on target tissues and are used to treat an array of musculoskeletal conditions to decrease pain and inflammation, stimulate collagen metabolism and wound healing, and promote fracture healing [8-10].

Lasers used therapeutically emit relatively low light energy [from a few milliwatts (mW) to 100 to 200 mW] for short periods of time (seconds to minutes) and produces insignificant changes in tissue temperature (measured to be around 1.0 °C). As such, this type of laser is often referred to as LLLT or photomodulation. The wavelength of the light emitted from lasers varies from >100 to > nanometer (nm) in the electromagnetic spectrum [8] so only wavelength above 193 are transmitted in the atmosphere. Lasers used to stimulate biological tissues were historically produced using a Helium-Neon (HeNe) gas mixture. Light is attenuated exponentially in tissue and the physical penetration depth is given by the distance over with the initial power or energy density dropped to 1/e or ~37% of its original value. The depth over which a sufficient dose can be delivered comprises multiple physical penetration depths and is more commonly quoted in the literature. Here we adopt the clinical usage of this term as the depth to which clinical affects can be achieved. HeNe has a wavelength output of 632.8 nm that is visible red light, is continuous and can penetrate 0.8 mm into tissue with indirect effects of up to15 mm [8]. Currently low level laser devices are commonly produced from semiconductor diodes composed of crystal compounds such as Gallium-Arsenide (GaAs) or Galium-Aluminum-Arsenide (GaAlAs), designed to emit laser energy at various specific wavelengths in the infrared range of the electromagnetic spectrum (730nm to 905nm). The infrared (IR)-laser light, GaAs, laser can penetrate up to approximately 5 cm into tissue with a wavelength of 904 nm and is pulsed [8]. The IR-laser, GaAlAs, laser has a wavelength of 830 nm [11, 12], is pulsed, and can penetrate approximately 2 to 3 cm into the tissue [10]. Hence, lasers with longer wavelengths penetrate deeper into the skin tissue than lasers with shorter wavelengths. There is experimental evidence to suggest that the biological effects and physical behaviour of lasers vary with the wavelength of light used [13-15]. The wavelength of red light has been consistently shown to biostimulate cellular responses including membrane permeability, intracellular calcium influx, and ATP production [14-16]. Laser driver technology considers the delivery of the therapeutic dose (J or J/cm2) either with a constant time average or as a pulse light source with low duty cycle but very high dose rate. The pulsed delivery of light allows higher dose-rates to reach deeper tissues, particularly for very short pulsed and low repetition rates. For example, a 905 nm continuous wave infrared laser allows 2.5 cm penetration of a clinically effective dose-rate, while a 905 nm super-pulsed infrared laser allows the same dose-rate even at a10 cm depth. Super-pulsed infrared laser allows high peak power (50 W) to be delivered in bursts of very short duration (200 nanoseconds). These brief pulses of light energy are delivered at frequencies of up to 10 kHz. Thus superficial tissues will not heat up due to the very short bursts. This (high peak power of short duration and high frequency) allows a therapeutic dose-rate to reach deep tissues. It is however important to note that the dose is not effected by pulsed delivery, only its rate of delivery during the actual emissions cycle of the laser. Dual channel lasers can combine both continuous and pulsed lasers to allow superficial and deep dose-rate delivery of laser energy. Thus laser drive technology allows penetration to deep tissues or more superficial tissue promoting acceleration of healing by reducing pain and inflammation while staying below the Maximal Permissible Exposure tolerance for tissue. Because of the relative ease of producing semiconductor diodes and the relative ability of infrared light to penetrate biological tissues, infrared lasers (GaAs; GaAlAs) are most often used clinically to treat musculoskeletal conditions involving structures located deep within the joint. Dosage of a laser treatment is calculated using the power output [milliwatts (mW)], the surface area of the laser beam (cm2) and the amount of time the laser beam is in contact with the skin (seconds) [8]. The wavelength of the laser device (nm) determines the quantum energy available for photochemical processes during laser exposure. Laser energy density is measured in joules per square centimeters (J/cm2) of tissue area and laser power emitted is expressed in mW.

Traditional Chinese Medical Science
Radial Artery: one of the surface superficial arteries. The reason to choose surface irradiation for the radial artery is the following:
1. Position of radial arteries is much superficial compared with parts of the body.
2. It is closer to the heart and the blood flow volume is larger, and with blood going through the radial arteries at per eight minutes(whole blood volume).
3. It's easy ti touch and locate and runs along the vein.
So the laser energy can be easily absorbed by blood cells, to ensure the good effect.
Ulnar Artery:
Ulnar artery and superficial palmar branch of the radial artery fit in to deep palmar arch, through the meridians of ulnar artery heart, for treatment of chest, consciousness disorders and this meridian site of the lesion.
Neiguan Acupoint: is at the two cross fingers inwards the first cross grain on the inner sie of the wrist, shown as below. In the meridian doctrine of traditional Chinese medicine, the neiguan acupoint belongs to the pericardium meridian and is one of the eight confluence points. Large quantity of experiments and clinical practices have certified that the meiguan acupoint has the following adjustment function to the heart:
1. It can adjust the abnormal heart rate in a bidirectional way. The high heart rate can e slowed down and the low heart rate can be accelerated;
2. It can increase the blood flow volume of the coronary artery in acute myocardial ischemia;
3. It can strengthen the myocardial contractility and improve the cardiac function.To choose low level laser irradiation at the NEIGUAN acupiont is considered by experts as"One of the most outstanding and effective methods to treat cardiovascular and cerebrovascular diseases.

QFA
1. How do I choose the power and treatment time?
For the power, It is divided into four levels.
For the time, It divided into 10 min, 20 min, 30 min, 40 min, 50 min, 60 min.
For general patient, we suggested for 30 min with the highest power.
It's suggested Twice or three times a day and 30 min per each treatment.
The time and power can be according to your own fitness scale or adaptedness gradually add per each treatment time to 10 min or 60 min.
After every 10 days treatment, pause 1 or 2 days. Then continues the next 10 days treatment.
2. How to operate the semiconductor laser therapeutic instrument?
Firstly, wear only for left hand. The device's back part correspond with the radial artery. If there is a lot of dirt on your nasal cavity laser probe or ear cavity laser probe before application, please clean it. When using nasal cavity laser probe, stick the nasal cavity head into your nose for 2-3 cm and clamp the nasal septum. Using way of ear cavity laser probe is the same as wearing common earphone. Press on/off key to turn on the device. You will see the LCD screen is on, only mode A is activated. Press Mode key to choose Red/Blue or both modes for laser therapeutic instrument.
Insert the nasal or ear or pain relief pad probes line into the socket, mode B is also activated. Press on/off key one second to start the treatment (notice: long press of the on/off key will shut down the instrument), you can see the laser coming out from the phototherapy instrument probe during the treatment. After the treatment is finished, long press on/off key to shut down the instrument. Store in a safe place after cleaning (gently wipe by tissue) the therapy head. Only one probe work each time, nasal cavity laser probe, ear cavity laser probe and laser pain relief pad can't work together.
3. How to find the Radial Artery?
Using two fingers of your right hand to position the outside of the left hand's first wrist line (See the picture). Then, use the instrument backpart of the Radial Artery laser acupoint correspond with the hand's Radial Artery to wear the instrument on your left hand.
4. May I choose do not use the nasal cavity irradiation?
We strongly recommend that should combine with the nasal cavity irradiation. Thus, can get the maximum treatment efficiency. Before using the nasal cavity probe, DO USE the small cap to protect on the head. Please clean your nasal cavity head with 0.9% normal saline (sold in drugstores), or gently wipe by tissue. Then, stick the nasal cavity probe into your nose for 2-3 cm and clamp the nasal septum.
5. What others should I pay attention to during the treatment period?
You do not need to change your other living habits, while you should develop a certain diet or do certain exercise if you have cardiovascular and cerebrovascular diseases, hypertension, diabetes, etc. in addition, please do not use ethanol to clean your nasal cavities and the phototherapy instrument head, since ethanol irritates mucosa and will damage the probe shell. It is suggested to clean with 0.9% normal saline (sold in drugstores) or gently wipe with a wet pa per towel.
6. May I choose a longer treatment time to enhance the curative effect?
You are suggested to use the instrument according to the time and magnitude specified by us. Because medical experiment has found out that the more energy the mucosal tissue of human body absorbs from soft laser will not necessarily enhance curative effect, since over radiation witl make the mucosal tissue to be less sensitive.
7. Will I feel anything during the treatment?
You will hardly feel any pain, harshness or other discomfort; however, since light luminance coming out of the therapy head is fairly high, please do not bring out the phototherapy head and directly observe the light with your eyes and it is better to close your eyes during the treatment. In the few beginning days, because of improved blood circulation state, very few patients will experience such normal phenomenon as dry throat, headache, worse rhinobyon, slight nose bleed, etc. If you have serious discomfort, you may
reduce the treatment time or power for each treatment, or reuse it after three days, the discomfort will disappear soon.
