Laser
Non-thermal and thermal effects
Use on open wounds
Chronic pain and acute treatment
More research demonstrating efficacy
Safe to use on most populations.
Ultrasound
Thermal and non-thermal effects
Closed wounds only
Not to be used over the eyes
Potential tissue damage if used incorrectly
Lack of research demonstrating efficacy
Should not be used on those with circulatory or neuropathic conditions, children or the elderly.
To summarise, Laser can be used on a wider range of injuries and conditions and has fewer contraindications to treatment than ultrasound. Ultrasound poses more of a risk in terms of potential tissue damage, mostly due to the thermal effects and danger of burns. Finally, there is more scientific evidence supporting the use of laser therapy for treating soft tissue injuries.
One study published in the American Journal of Sports Medicine in 2008 (Stergioulas et al) demonstrated a significant improvement in pain levels in those with Achilles tendinopathy when laser was used in conjunction with eccentric strengthening (compared to sham laser and eccentric strengthening).
However, the lack of evidence supporting the use of ultrasound therapy may be due to the wide variation in treatment settings used among different studies which can have dramatic effects on the outcomes. Ultrasound also has a pro-inflammatory effect which may explain why studies looking into the anti-inflammatory effect have shown no effect.
Conclusion
In conclusion, it appears that laser therapy has more applications in treating soft tissue injuries and also poses less risk of cell damage. Whilst many clinicians regularly use ultrasound and have seen positive results in the clinical setting, there is less research to back this up than there is with laser therapy.

Questions and Answers about Class 4 Cold Lasers
There is a big difference between class 3 and Class 4 products.
There is a lot of controversy in the cold laser market about class 4 lasers and their performance when compared to lower power cold lasers. Many class 4 lasers are not technically "cold" since they can warm the treatment area once above about 4 watts but there is really no census about what is the best name for lasers used for photobiomodulation but they all serve the same goal so we will call them both cold lasers and class 4 lasers on this site.
One issue manufacturers debate the most about is about how much power works best for photobiomodulation. Class 4 manufacturers would say more power means faster treatment times and higher dosages that make it is worth the extra cost. Class 3 manufacturers, on the other hand, say lower power promotes better healing with no risk of burning anyone. So who is right?
This article will try to clear the air. Manufacturesr tend to highlights their products' advantages and bash everyone else's lasers. All the lasers on the market can provide good results (even some of the lower power systems) but they all try hard to make their laser stand out in the crowd. Truthfully, there is some truth to all the claims, however, they are typically taken out of context so should not effect your decision about what product to buy.
Below is a table that shows some common claims and some of the underlying facts behind the claim. Always keep in mind that almost every class 4 laser has the option to turn down the power when it is appropriate so you have more flexibility with a higher power pulsing/CW class 4 laser.
There is a big difference between class 3 and Class 4 products?
Yes and No.
Yes. Once you get above 5 watts, the laser diodes are installed in a cooled housing and you use a fiber optic cable to transfer the power to the handheld probe. This adds a lot of complexity to the system.
No, the cutoff for a class 4 laser is 0.5 (1/2) watts per beam. This means that, for example, the Avant LZ30 with 2 beams at .450 watts per beam is more powerful than some Class 4 lasers but is a class 3b. The Apollo is Class 4 but uses probes that are extremely similar to the Class 3b probes used byThor. It is just a matter of picking individual laser diodes above or below .5 watt output. The line between class 3 and class 4 lasers is very blurry.
Class 4 lasers are not appropriate for home use?
False, however most class 4 systems do require extra training to make sure the user is safe. Many home users start out getting therapy in a doctor's office but want the convenience of therapy at home. In this case, users can simply adapt the protocol that is already working for use at home to save time and money. Systems like the Apollo cold laser use a divergent beam and a timer as the only variable so less training is required. For pain control, class 4 power lasers, with higher power and continuous wave, are the best.
Too much power is not as effective for healing?
This statement has NOT be proven by an independent study; it has only been shown by studies paid for by lower power laser manufacturers who use the study to discredit class 4 systems. Higher dosages are better for pain control but higher-end Class 4 laser have adjustable power so when you want less power, you simply turn it down. When you need more power for better pain control, you turn it up.
Class 4 lasers are not worth the money?
False. Using a class 4 laser for less than 20 minutes per day, you probably don't need to spend the extra money. That being said, for many people, higher dosages and shorter treatment times are a key to great results. If you are not concerned about therapy times, flexibility or giving your patients the maximum pain relief, then a lower power product is fine. Class 4 lasers are for doctors and home users who want to have every option available without limitations for any condition. State-of-the-art class 4 lasers can be purchased for less than $12,000, however mediocre class 3b laser for over $15,000. You get what you pay for with most class 4 systems
Class 4 lasers are better for pain control?
Class 4 lasers have shorter therapy times?
Class 4 lasers are better for treating larger areas?
Yes to all of these claims. Higher power lasers provide better pain control in a shorter period and can cover large areas much faster than a lower power lasers. The key here is not necessarly the class but the total power output of the system. Higher power allows for more flexibility. Everyone in the market seems to agree that more power is better for pain control, better for larger areas and will shorten the time it takes to get the optimum healing or pain control density.
Class 4 laser are dangerous?
Yes. In the wrong hands, a class 4 cold laser can cause damage just like a scalpel, a bad drug prescription or any of the other tool doctors use every day. This is not a good reason to not have the tool. With proper training and adhearing to safety precautions, class 4 lasers are safe.

Biological Effects of High Power Laser Therapy
Many research trials and clinical studies have been performed to determine the positive effects of Laser Therapy for a wide range of clinical conditions. The following list is a compilation of the most widely studied biological effects of Laser Therapy.
Effect #1:
Pain Relief: Laser Therapy relieves pain through several different biological mechanisms:
- It blocks the pain signals transmitted from injured parts of the body to the brain. This makes the nerves less sensitive and significantly reduces perception of pain.
- It helps to decrease inflammation and swelling.
- It increases the production and release of natural pain killing chemicals within our bodies.
Effect #2:
Inflammation Reduction:Laser Therapy causes the smaller arteries and lymph vessels of the body to increase in size, a mechanism called vasodilation. It is this process that allows inflammation, swelling and edema to be cleared away from injury sites more effectively as well as assisting in the more rapid resolution of bruising. Vasodilation also promotes lymph vessels to drain which aids in the healing process.
Effect #3:
Faster Wound Healing:Your skin and other body tissues are made up primarily of collagen. Fibroblasts are the building blocks needed to create collagen. Laser Therapy stimulates the production of fibroblasts and therefore allows collagen to be made. Laser Therapy, is therefore, an effective treatment for open wounds and burns.
Effect #4:
Improved Nerve Function:Laser light speeds up the process of nerve cell regeneration. This allows for a shorter recovery time after a nerve injury. Laser Therapy also increases the strength of action potentials, or signals sent along nerve fibers. The increased signal strength improves overall nerve and muscle function. It is for these reasons that Laser Therapy is so effective at reducing the symptoms related to nerve injury – namely sharp pain, numbness, tingling and burning.
Effect #5:
Accelerated Tissue Repair and Cell Growth:The light emitted by therapeutic lasers penetrates into tissues to stimulate the energy production in cells. The increase in cellular energy enables the cells to absorb nutrients and expel waste products more rapidly. This dramatically accelerates the repair of injured tissues and leads to faster tendon, ligament and muscle healing.
Effect #6:
Increased Metabolic Activity:Laser Therapy also has a significant impact on individual blood cells that pass through the laser beam during treatment. The laser light enables the red blood cells (RBCs) to be able to carry more oxygen and nutrients to the rest of the body. This allows for increased metabolic activity and production of specific enzymes. Both of these effects can be felt throughout the entire body and are not limited to the area exposed to the laser.
Effect #7:
Improved Blood Flow:Laser Therapy significantly increases the formation of tiny blood vessels, called capillaries, within damaged tissues. More capillaries allow more blood flow to the area of injury. This results in accelerated healing as wounds are closed more rapidly and scar tissue formation is reduced.
Effect #8:
Reduced Formation of Scar Tissue:After tissue damage has occurred through cuts, burns or surgery; scar tissue often forms around the injury site. Laser Therapy reduces the formation of scar tissue by speeding up the healing process. It does this by improving blood flow to the injured area and thereby allowing for the more effective removal of waste products. Faster healing always leads to less scar tissue formation.
Effect #9:
Enhanced Immune Function:ATP (adenosine tri-phosphate) is the single most important form of energy that powers ALL chemical reactions within ALL cells of the body. When laser light is absorbed by chromophores, which are embedded within most cells of the body, this activates the production of ATP. Higher energy production leads to faster and more efficient cell function. This is especially true of immune-specific cells that are exposed to Laser Therapy. This improved efficiency aids the immune system in fighting off undesirable microbes and pathogens.
Effect #10:
Acupuncture Point Stimulation:Laser Therapy is also an effective alternative to traditional acupuncture treatment. Traditional acupuncture delivers therapeutic effects through the stimulation of acupuncture points throughout the body. This is achieved by piercing the acupuncture points with needles and then twisting the needles by hand, tamping them or connecting them to electrical stimulation devices. Laser Therapy may be used to stimulate the same acupuncture points without the need for invasive needling or similar mechanical stimulation.

Laser Acupuncture
A relatively new method of stimulation, laser acupuncture usually uses low-energy laser beams — instead of traditional acupuncture needles — to influence the flow of current at the acupuncture points. Beyond conventional medicine, this procedure is usually the preferred procedure for effective treatment of painful conditions such as carpal tunnel syndrome, tennis elbow, arthritis of the knee, and chronic headache in children. Most practitioners have an in-depth knowledge of traditional Chinese medicine and a clear understanding of how various acupuncture points function.
A laser acupuncturist typically aims a beam of light from a laser tube onto an acupuncture point, stimulating it similar to the way acupuncture needles do. The visible red laser beam, radiating from helium and neon gases, usually heats up the point. During the procedure, a practitioner may hold the beam steadily for a period that can range from ten seconds to a maximum of two minutes. The duration of the beam usually depends on the amount of tissue the laser must penetrate, and the power the acupuncturist needs to apply on a point. Sometimes, a practitioner may also have to use invisible infrared lasers.
Laser acupuncture is primarily used to serve two purposes: an anesthetic effect and the stimulation of acupuncture points in a therapeutic program. The procedure has some distinct advantages over the traditional needle method. Many patients who are usually afraid of needles, such as children, prefer the lasers. Use of a laser makes it a typically noninvasive, aseptic procedure, which significantly reduces the pain and recovery time associated with invasive treatments. Generally, this method can also treat the same range of complaints as needle acupuncture.
While laser therapy significantly reduces patient trauma, and is usually a good choice for treating conditions where the risk of cross infection is high, the effectiveness of this treatment is often limited to peripheral points. The acupressure points on a patient’s hands, feet, and ears often respond to laser treatment, but deeper abdominal points do not usually benefit, as most of the laser beams used cannot penetrate beyond 0.19 inches (5 mm).
Some acupuncture clinics have invested in a user-friendly and intelligent laser acupuncture system. This relatively new system can largely be controlled and monitored remotely over the Internet. In such systems, the software typically automatically recognizes the meridian points, and monitors the laser beam for more controlled treatment.
