At Pioneer Spine and Sports Physicians, our physical therapy department uses advanced Class IV laser therapy to treat a wide range of musculoskeletal conditions. It is a non-invasive treatment that uses light energy to promote healing and reduce pain. In this therapy, photons (light particles) penetrate the skin to stimulate cellular activity and improve circulation, helping tissues heal faster. Class IV lasers are high-power lasers that deliver therapeutic energy to muscles, ligaments, and joints.
How Laser Therapy Works
Laser therapy works through a process called photobiomodulation (PBM). When laser light penetrates the skin, it interacts with the mitochondria in cells, specifically the cytochrome c complex. This interaction increases cellular metabolism and stimulates the body's natural healing processes. The result is improved circulation, reduced inflammation, and decreased pain. By flooding the injured tissue with photons, these lasers provide fast and efficient treatment for acute and chronic conditions.
When is Laser Therapy Recommended?
Laser therapy is often recommended for treating a variety of musculoskeletal conditions, including:
- Chronic pain
- Soft tissue injuries
- Joint pain
- Tendonitis
- Ligament sprains
- Post-surgical recovery. It can be used as an alternative to prescription medications or surgery, and it is particularly effective in reducing pain and inflammation.
What Does Laser Therapy Feel Like?
During laser therapy, patients typically feel a soothing warmth in the area being treated. The sensation is often described as relaxing, especially when combined with a massage-ball treatment head. Many patients report immediate pain relief during the session, particularly with higher-power lasers like LightForce® Class IV devices.
Is Laser Therapy Safe?
Yes, laser therapy is considered safe when administered by a trained professional. Class IV lasers were cleared by the FDA in 2004 for pain reduction and increasing circulation. However, safety precautions like wearing protective eyewear are necessary during treatment to prevent eye injury. The treatment is non-invasive and drug-free, making it a safe alternative to surgery and medications.
How Long Does a Therapy Session Last?
Laser therapy sessions are generally quick, lasting between 3 to 10 minutes depending on the size, depth, and severity of the condition being treated. The high power of Class IV lasers allows therapeutic doses to be delivered in a short amount of time, making it a convenient option for both patients and clinicians with busy schedules.
How Often Will I Need to Get Treated with Laser Therapy?
Most clinicians recommend 2-3 laser therapy treatments per week when beginning treatment. The cumulative nature of laser therapy means that its benefits build up over time, making early and frequent treatments more effective. As symptoms improve, treatments can be administered less frequently.
How Many Treatment Sessions Will I Need?
The number of treatment sessions needed varies depending on the condition and how the patient responds to therapy. Most treatment plans involve 6 to 12 sessions, with more sessions required for chronic conditions. Your healthcare provider will create a treatment plan tailored to your needs.
How Long Will It Take Until I Notice a Difference?
Many patients experience some relief immediately after their first treatment, such as a warm sensation and reduced pain. However, the benefits of laser therapy are cumulative, meaning noticeable improvements often occur after a few sessions. Continued treatments will provide ongoing benefits.
What Are the Contraindications for Laser Therapy?
Certain situations contraindicate the use of laser therapy, including:
- Overgrowth plates in children
- Over the abdomen or lower back in pregnant women
- Around glandular tissues (e.g., thyroid, testes, ovaries)
- Over pacemakers or internal pain pumps
- Patients taking photosensitive medications like steroids or antibiotics
What Are the Side Effects of Laser Therapy?
Laser therapy has minimal side effects. Patients may experience temporary redness or warmth in the treated area due to increased blood flow. In rare cases, improper dosing can lead to temporary swelling or nerve irritation. However, these effects usually resolve within 24 to 36 hours. When administered correctly, laser therapy is a safe and effective treatment option with few side effects.
