Plantar fasciitis is the most common cause of heel pain in adults.

It causes a stabbing pain in the bottom of your foot near your heel, most notably with the first step out of bed in the morning. Ouch! As you stand up and walk around, the pain may subside, but it will often return after long periods of standing, or when you stand up after sitting for a while.

‘Plantar’ refers to the sole, or bottom of your foot. ‘Fasciitis’ is inflammation of the thick band of tissue that connects the heel to your toes. The plantar fascia also connects to the tissues that run down your leg and Achilles’ tendon. Sometimes problems such as trigger points in the muscles in your leg (called the soleus and gastrocnemius) can cause or contribute to the problem of plantar fasciitis. If that is the case, treatment may be needed in the leg – but more on that later.

Plantar fasciitis is more common in runners but is also seen in the very active dancers, the overweight and those who wear shoes with inadequate support. Your foot mechanics can also increase chances of developing plantar fasciitis. A flat foot, a high arch, or an abnormal pattern of walking can put added stress of the plantar tissues.

It most commonly affects patients between ages 40 and 60, and certain occupations that require long periods of standing such as factory workers, teachers, and store clerks can be at increased risk. Standing on a hard surface increases the risk, so someone forced to stand for a long time should use a cushioned pad or carpet.

Diagnosis of plantar fasciitis usually does not require diagnostic imaging, but occasionally an x-ray may be taken to determine whether a heel spur is present. Heel spurs are bony projections from the bottom of the heel along the course of the plantar fascia. Spurs usually require invasive procedures, such as surgery to correct. Whereas since plantar fasciitis is an inflammatory condition, surgery is NOT recommended.

In the past, treatment for plantar fasciitis consisted of the following: icing, foot orthotics, heel pads and cushions, anti-inflammatory drugs, and steroid injections. But there is a new solution that is giving patients across the country relief from plantar fasciitis – regenerative, non-invasive pain management with a class 4 therapy laser.

  • Class 4 therapeutic lasers deliver red and infrared photons of laser light into the tissues.
  • The red photons are absorbed by more superficial tissues, while the infrared photons penetrate deeper into the body.
  • The treatment is non-invasive and painless, to the contrary you would only feel a mild warming sensation during the treatment.
  • The photons of light are absorbed by different components (water, oxygenated hemoglobin, various enzymes) in your body, resulting in enhanced blood flow, improved tissue oxygenation and resolution of inflammation.
  • For someone suffering from plantar fasciitis, the pain “relief” can sometimes be noticed after just the first treatment!
  • Treatment times are about five minutes, or maybe a little longer if treatment is also required in the leg. Remember how we said that sometimes trigger points in your leg muscles can cause or contribute to plantar fasciitis? Those trigger points cause a chronic shortening of the muscles, essentially pulling on the plantar fascia 24 hours a day, making your plantar fasciitis pain even worse.
  • Treatments are usually delivered three times a week for four to six weeks – but your clinician will determine the schedule and number of treatments that is best for you.
  •  A very high percentage of patients will get relief from the pain, discomfort and disability caused by plantar fasciitis within six weeks once they receive the class 4 therapy laser treatments

Tissue injuries constitute a range of specific injuries. For example, anyone who has or had a large bruise that took several days to heal experienced a contusion, which is a tissue injury. This injury is in the soft tissue injury class. 

  • Sprains and strains involve a tear in a tendon, usually the ankle and knee.
  • Bursitis results from inflammation of liquid surrounding joints.
  • Tendonitis comes from overusing a tendon, and common in athletes.
  • One application of class IV laser therapy that is started to gain acceptance is pain management after surgery.

These soft tissue injuries are treatable with class IV laser therapy.


Photobiomodulation (laser therapy) is a scientifically proven modality and will be a valuable modality in all fields of health care in the years to come. Class 4 therapy lasers could possibly be the single piece of medical technology that has changed the lives of more human and animal patients in the last decade.

Potential Benefits of Class 4 Laser

What does research tell us about potential Class IV laser therapy benefits? Some of the most popular applications for this type of laser treatment are:

1. Can Reduce Inflammation, Aches and Pains

Intended uses of Class IV laser devices include:

  • Promoting relaxation of muscles and providing relief from muscle spasms
  • Reducing minor joint aches, pain and stiffness
  • Temporarily decreasing arthritis symptoms
  • Helping to increase blood circulation

A recent review of published studies has found that photobiomodulation treatments appear to be “effective, safe treatments in a variety of conditions,” when devices were used for indications “including pain, cognitive dysfunction, wound healing, diabetic macular edema, and postprocedural side effects.”

Their mechanism of action is photochemical, meaning that light energy causes chemical reactions inside cells that help to reduce inflammation and pain. This is a key, distinguishing factor that sets these treatments apart from other approaches.

Class 4 lasers are also now being recognized as optimal devices for reaching deep tissues that are tied to pain. Higher doses of light and higher output are needed to deliver appropriate doses of energy, due to the large portion of light that is absorbed, reflected or scattered at the skin’s surface. Less powerful lasers may not work if they cannot penetrate deep enough to provide any stimulating effect.

Other considerations in the overall depth of penetration and success of treatment include specific wavelengths and how they interact with the skin. Some light is absorbed more at the surface with darker skin or hair color than another wavelength. Additional features of a medical laser can include continuous wave or pulsing operations that also assist in achieving better results.

2. May Help with Recovery from Acute and Chronic Injuries

Using Class IV laser therapy for overcoming both acute and chronic injuries, such as tendonitis or damage to the knees, are among the most common applications. Not only do treatments address damaged tissues in specific areas of the body (knees, shoulders, back, etc.), but they also affect related issues. Overcompensation in some muscles, back pain or poor posture tied to overuse and inflammation may be improved.

Treatments have been shown to provide relief and boost recovery by reducing pain and inflammation as well as stimulating nerve regeneration, muscle relaxation and immune system response.

3. Used to Treat Skin Conditions Including Wounds and Scars

Emerging research, in both human and veterinary applications, suggests that photobiomodulation can lead to significant stimulation of healing in many types of wounds, burns and scars. Therapy lasers are used on a regular basis for managing wounds in the veterinary market (feline, canine and equine).

However, lasers are not currently cleared by the FDA specifically for wound therapy in humans. A physician may use a therapy laser for wound care but this would be considered off-label usage. It is anticipated that these applications will be become more prevalent as new studies are published and the FDA grants specific clearance.

Additional post-surgery applications with therapy lasers are emerging as a viable treatment to reduce infections and induce faster healing times, by up to 50 percent, for surgical incision sites.

4. May Help Treat Neuropathy

Therapy lasers are increasingly being used as an effective treatment for neuropathy and there are a number of clinical studies indicating positive outcomes.

Some companies in the laser therapy business have been selling lasers on the internet for home use, often touting the same results as devices used in a medical office. These lasers are typically Class I, II, III or LED products and will have little or no therapy benefits due to their low power.  A powerful product like a Class IV laser is essential for providing the most benefits.

In addition to tissue healing at the cellular level are other significant biological effects. With treatment from laser light, cells get rid of waste products quicker. The result is quicker tissue healing of tendons, ligaments, and muscles. Class IV laser therapy stimulates the growth of fibroblasts; these collagen-based cells lead to wound and tissue healing. Once again, this promotes faster healing.

Tissue healing cannot occur without blood flow. Class IV laser therapy aids in the development of new capillaries in wounded tissue and temporarily widen other blood vessels. This helps wounds heal faster because of increased blood flow.

A leading cause of pain is scar tissue or the formation of fibrous tissue. Consequently, class IV laser therapy for tissue healing results in less scarring. Another leading cause of pain is inflammation. Laser light produces vasodilation, an anti-endemic effect that triggers the body’s lymphatic drainage system.

Laser light also helps reduce nerve sensitivity, reducing pain signals sent to the brain. In tissue healing with class IV laser therapy, the brain and adrenal gland increase endorphins and enkephalins, the body’s natural pain killers. Laser light produces photons that get absorbed by chromophores, which in turn promotes immunoregulation and longer-lasting pain relief.

CLASS 4 LASER FOR HEALING [ by DoctorZo.Health ]

About Class IV Laser

Class IV lasers are more expensive than older class lasers. The expense does not go to waste, because the treatment is very effective for the following conditions:

  • Soft Tissue Trauma
  • Muscle and Tendon Sprains
  • Back and Neck Pain
  • Carpal Tunnel Syndrome
  • Myofascial Trigger Point
  • Tennis/Golf Elbow
  • Plantar Fasciitis
  • Degenerative Joint Conditions
  • Rheumatoid Arthritis
  • Osteoarthritis
  • Nerve Pain
  • Sports Injuries

How long does each treatment take?

Higher power of Class IV lasers treatment times are less. Most treatments take minutes. The typical treatment is 3 to 9 minutes, depending on the size of the area treated.

How long before the results are felt?

You may feel improvement in your condition after the very first treatment. Sometimes you will not feel improvement for a number of treatments. Each treatment is cumulative and results are felt after 3 or 4 sessions.

How often should a patient be treated?

Acute conditions may need daily treatment, particularly if they are accompanied by significant pain. More chronic problems respond better when treatments are received 2 to 3 times a week, tapering to once a week.

  • Acute problems usually need 4 – 10 total treatments.
  • Chronic problems can take up to 10 – 20 treatments.

What’s different about the Summus Class 4 laser used by Doctor Zo?

It’s the only LASER on the market with a four Wavelength/Triple Delivery Mode. Summus was the first to employ three infrared wavelengths simultaneously of 800 nm, 905 nm, and 970 nm and combine them with a 660 nm visible beam. These Four Wavelengths are more efficient, healing the tissue while also aiding in pain relief. Combine this with Three Distinct Delivery Modes (Continuous Wave, Frequency Modulated, and Intense SuperPulse), and he has a therapeutic laser solution that offers as much variety as the conditions and patients he treats.

Class IV therapy laser treatments by Doctor Zo provide a deeper depth of tissue penetration and ultimately provide a dose that results in positive and reproducible outcomes. Higher wattage also results in faster treatment times and provides results unachievable with low wattage lasers. These lasers provide a wider range of treatment options than Class I, II, and IIIb lasers due to their ability to treat both superficial and deep tissue conditions. Laser Therapy is the use of red light to create therapeutic healing. Class IV effects include less healing time, less pain, better circulation and decreased swelling. Laser treatment has been FDA cleared since 2002 and is now widely used in the United States.

What are the benefits of Laser Therapy?

Laser Therapy stimulates tissue repair, healing and growth. The red laser light accelerates wound healing, decreases inflammation and pain, and scar tissue formation. Class IV laser treatment provides great results for chronic tissue pain and has virtually no side effects.

How Does Laser IV Treatment Work?

Infrared light stimulates tissues at the microscopic level helping to increase transportation of nutrients to cells in the body. This initiates the production cellular energy and improves tissue function and health.

What Does Class IV treatment feel like?

There is little or no sensation during laser theapy. Every now and then you can feel mild, warm or tingling. Areas that hurt prior to treatment may be sensitive before pain goes away.

Are there any side effects or associated risks?

Very few side effects have ever been noticed. Occasionally some old injuries or painful spots may feel agitated for a few days, as the healing process completes.

Can it be used in conjunction with other forms of treatment?

Yes! Laser Therapy is often used with other forms of therapy, including physical therapy, chiropractic adjustments, massage, soft tissue mobilization, electrotherapy and even following surgery. Other healing modalities are complementary and can be used with laser to increase the effectiveness of the treatment.

Class 4 Laser Therapy Benefits

The benefits of class 4 laser therapy include reduced pain and swelling as well as improved range of motion but a class 4 laser has some very interesting effects that we don’t notice right away.

A class 4 laser increases tissue regeneration which is why you heal faster but it also accelerates soft tissue and bone repair. This kind of laser therapy can also improve nerve regeneration & function as well as impact your cells to increase cell metabolism, enzymatic responses, collagen production, and promote angiogenesis (the creation of new blood vessels). So yes, you walk away from class 4 laser therapy feeling better but the therapy continues to work on the cellular level to improve your musculoskeletal health after you leave the office.

We use class 4 laser therapy on a range of issues including chronic knee pain or arthritis, chronic Achilles,’ tendonitis, elbow pain or tendonitis in the elbow, and chronic wrist pain. We are able to use the class 4 laser on a wide range of injury sites and extremities to provide relief to our patients.

Now you might be wondering what it feels like to get class 4 laser therapy. We find that many patients think that laser therapy will hurt and they’re pleasantly surprised to learn that they will feel some soothing warmth in the area we’re treating but certainly no pain. Class 4 lasers provide pain-free relief to many of our patients and can also be used in conjunction with other treatments like Spinal adjustments.
