Chronic pain is the most common cause of long-term disability. As a result, most conditions requiring physical therapy are associated with some degree of inflammation and pain. These symptoms usually lead to functional limitations, decreased strength and mobility. Physiotherapists use a combination of manual therapy, activity therapy, patient education and physical modalities when developing a treatment plan in order to increase efficiency and get the maximum benefit. There are many factors to consider when considering the use of a particular treatment method: ease of use, time efficiency, non-invasiveness and speed of benefit. Low Level Laser Therapy (LLLT) is one of the most popular treatment modalities in physiotherapy.

 

Laser Light Therapy in Physiotherapy

 

Low-level Laser Therapy (LLLT) provides immediate relief from acute neck pain and sustained pain relief 22 weeks after completion of treatment in patients with chronic neck pain, according to an Australian study. Physiotherapists use laser light therapy to diagnose a wide range of chronic pain including arthritis, neuropathy, muscle strains, fractures, pain relief and TMJ.

Principles of Laser Therapy

 

Laser therapy uses light at very short wavelengths (600-1000 nanometres) to penetrate the body's tissues to promote tissue healing and reduce pain and swelling. Particles called photons combine in waveforms to form light. Light travels through the layers of the skin (dermis, epidermis and subcutaneous or subcutaneous fat tissue) at all wavelengths in the visible range. However, of all the light waves in the visible spectrum, those in the near-infrared band penetrate the deepest. When Low Level Laser light waves penetrate deep into the skin, they optimise the immune response in the body's bloodstream. This produces anti-inflammatory and immunosuppressive effects. It has been found that light transmitted into the bloodstream through light therapy has positive effects throughout the body as it provides vital oxygen and energy to every cell.

 

The types of light used in laser light therapy are most commonly red or near-infrared light. These forms of light appear in the electromagnetic spectrum just above visible light. Numerous studies have found that photons, especially photons in the red or near-infrared spectrum, have therapeutic properties at the cellular level, meaning that cells are able to absorb photons. The cells then use these photons to make additional adenosine triphosphate (ATP), which produces energy for the body. The ability to produce this extra energy helps to accelerate the body's natural healing process.

 

In addition, laser light therapy is a popular form of treatment, and in addition to its therapeutic benefits, it is non-invasive and painless with treatments usually lasting 5 minutes or less. Although laser therapy is usually performed two to three times a week, most people notice an improvement in their treatment after the first or second treatment, so it also works quickly.

 

Studies have shown that LLLT accelerates the inflammatory process by stimulating the mitochondrial chromophores. This is important because this stimulation increases the activity of the respiratory chain, which in turn promotes ATP synthesis, cellular repair and reproduction.

 

With these wide-ranging benefits, LLLT is suitable for a variety of therapeutic options. Below we discuss the use of LLLT in physiotherapy.

Patients have a wide variety of pain conditions, thus requiring a wide variety of research and treatment approaches.

 

The cost of unrelieved pain can be prolonged hospital stays, increased rates of rehospitalisation, increased outpatient visits, and reduced ability to function adequately, resulting in loss of income and insurance coverage.

 

In physical therapy, pain management protocols are a combination of hands-on therapy, therapeutic exercise, and therapeutic modalities. As we have discussed, research has repeatedly shown that low-intensity laser therapy is a physical therapy effective partner in physical therapy, especially when low-level laser therapy is combined with ultrasound therapy. Low Level Laser Therapy is not only effective in reducing pain, but it is also non-invasive, cost effective and time saving. The advantages of low-intensity laser therapy for various diagnostic purposes make it an important tool in the practice of physiotherapy.
