How Does Cold Laser Therapy Work?

If you're exploring treatment options for a persistent injury or ongoing pain, you may have come across cold laser therapy — also known as Low Level Laser Therapy (LLLT). Here's a breakdown of what it is, how it's used in physiotherapy, and what to expect from a session.

What Is Cold Laser Therapy?

Cold laser therapy uses low-intensity light applied directly to the skin over an area of pain, inflammation, or injury. Unlike surgical lasers, it doesn't cut or burn tissue — the light is applied at a level intended to interact with cells in the treated area without generating significant heat. It's non-invasive and generally painless.

What Happens During Treatment?

During a session, your physiotherapist applies the laser device directly to the skin over the target area for several minutes. There's no sensation of heat or discomfort for most patients — many describe feeling nothing at all, or a mild warmth.

Cold laser therapy is rarely used on its own. At Elanora Physiotherapy, it's typically combined with manual therapy, targeted exercise, and other physiotherapy techniques as part of a broader, individualised treatment plan.

What Might It Be Used For?

Physiotherapists may consider cold laser therapy as part of a treatment plan for:

Tendon injuries (e.g. Achilles tendinopathy, tennis elbow, rotator cuff issues)

Joint pain associated with osteoarthritis

Muscle strains and soft tissue injuries

Recovery support following soft tissue surgery

Persistent or chronic pain presentations

Whether it's appropriate for your specific injury depends on an individual assessment — it isn't a one-size-fits-all treatment, and your physiotherapist will discuss whether it fits your recovery goals.

Is There Evidence Behind It?

Low level laser therapy has been studied for its role in supporting pain reduction and tissue recovery, and it's used by physiotherapists internationally as one tool among several. As with most physiotherapy modalities, results vary between individuals, and it works best when combined with an active, individualised rehabilitation plan rather than used in isolation.

Thinking About Trying Cold Laser Therapy?

If you're dealing with a nagging injury, joint pain, or a soft tissue issue that hasn't resolved with other approaches, it may be worth discussing cold laser therapy with your physiotherapist. At Elanora Physiotherapy, our team can assess your condition and let you know whether it's a suitable addition to your treatment plan.
