Sue loves spending time with her grandkids. But, lately, she has been struggling with basic movements such as walking in the park or bending down to pick up toys. She tries a few stretches and rubs her stiff neck but in vain. Chronic pain or restricted mobility is a common problem in Canada for various reasons. In most cases, physiotherapy helps. Laser therapy, a physiotherapy modality, has shown effective results in reducing pain in adult patients<\/a> with musculoskeletal disorders. But, is this the right treatment for you? Let\u2019s find out.<\/p>\n

What is Laser Therapy?<\/strong><\/h2>\n

Laser stands for Light Amplification by Stimulated Emission of Radiation. <\/em><\/p>\n

In physiotherapy<\/a>, laser therapy is a specific treatment approach where a trained therapist applies low-level laser light on the areas of your body that ache or feel stiff. The process is also known as Low-Level Laser Therapy or LLLT.<\/p>\n

LLLT is non-invasive. It generates a single wavelength of light and primarily affects the functioning of connective tissue cells. The low-level light accelerates tissue repair and also acts as an anti-inflammatory agent. It is effective in treating a wide range of musculoskeletal disorders among people of various ages.<\/p>\n

Common myths regarding laser therapy<\/strong><\/h3>\n

Burns or feels painful<\/strong><\/h4>\n

LLLT uses low-intensity light that penetrates the skin without emitting heat or causing discomfort.<\/p>\n

Instant results<\/strong><\/h4>\n

LLLT works cumulatively. While some may find relief after the first session, others may need multiple sessions to feel completely better.<\/p>\n

Relieves pain only<\/strong><\/h4>\n

Low-level laser therapy<\/a> reduces inflammation, improves circulation, boosts healing and promotes cell regeneration as well.<\/p>\n

Caters to only athletes or serious injuries<\/strong><\/h4>\n

Anyone recovering from chronic conditions or injuries can benefit from laser therapy, including seniors, desk job workers and athletes.<\/p>\n

How Laser Therapy Works in Physiotherapy?<\/strong><\/h2>\n

Laser therapy in physiotherapy or LLLT uses specific wavelengths of light (632 to 904 nm) to promote cellular regeneration and tissue healing. The low-intensity light penetrates the skin and interacts with cells without causing thermal damage or side effects.<\/p>\n

What\u2019s the science behind laser therapy?<\/strong><\/h3>\n

Absorption of the laser light- <\/strong>The therapist detects the affected areas and applies the light on them. Specific molecules within the cells (primarily the mitochondria, which is the cell\u2019s powerhouse of energy) absorb the light particles.<\/p>\n

Photobiomodulation- <\/strong>Once the light is absorbed, it triggers a process called photobiomodulation where all the biological processes within the cells are activated.<\/p>\n

Cellular responses- <\/strong>Photobiomodulation leads to several benefits such as enhanced blood circulation, reduced swelling, tissue repair and healing.<\/p>\n

How Does Laser Therapy Benefit You?<\/strong><\/h3>\n

The benefits of laser therapy are related to the cellular responses triggered by the process called photobiomodulation, as discussed above.<\/p>\n

Pain Relief- <\/strong>Laser therapy reduces pain by stimulating cellular repair and reducing inflammation. The light source treatment blocks pain signals and reduces nerve sensitivity, reducing chronic and acute pain.<\/p>\n

Improved Blood Flow<\/strong>– LLLT facilitates the flow of nutrients and oxygen to injured cells.<\/p>\n

Increased ATP Production-<\/strong><\/p>\n

Reduced Inflammation- <\/strong>Laser therapy controls swelling and promotes faster recovery.<\/p>\n

Better mobility- <\/strong>The laser treatment helps regain movement in stiff or injured joints.<\/p>\n

Post-surgical rehabilitation- <\/strong>Laser therapy reduces scar tissue formation and promotes faster healing.<\/p>\n

All in all, laser therapy is used in physiotherapy to treat a wide range of musculoskeletal disorders that cause pain, limited mobility and discomfort. It is effective in treating conditions like arthritis and nerve pain.<\/p>\n

Which Conditions are Treated by Laser Therapy?<\/strong><\/h2>\n

Laser therapy is prescribed for various musculoskeletal, neurological, and inflammatory conditions. Here are some of the most common ones:<\/p>\n
