Not invented here

I had a meeting with the Chief Exec of the UK’s premier cancer research hospital, last year. He was genuinely interested by my pitch about LLLT. He said I should meet his pain team to present data on Oral Mucositis (OM). Eventually a meeting was set and I gave my best to the Head of Pain Services. Lets call him Dr Fred. Dr Fred listened patiently then, when I had finished, he gave me some feedback: 1) he did not like the company logo 2) he accepts the mechanism of action but 3) LLLT achieves too many things and 4) he had to go to another meeting. A surgeon friend of mine offered to go persuade Dr Fred and they had two hour meeting. Dr Fred said he would pitch it to his team, but after a few weeks chasing for an update, he said that nobody was interested.

How can that be when (according to the article in this months literature watch by Rene-Jean Bensadoun and Raj Nair) there is no consensus on a single agent or agents that can be used either prophylactically or therapeutically to reduce severity or duration of oral mucositis, and yet four associations/agencies* either suggest or recommend LLLT for OM.

Could it be the case that they did not discover LLLT for OM so they are not interested? The good news is that there are three cancer hospitals in three different countries coordinating to run a multi centred trial with THOR lasers so maybe then we can get some interest.

How Photobiomodulation Therapy Works (video cartoon)

A short introduction to how the Photobiomodulation behind THOR lasers effects the body.

PBM Therapy has a photochemical effect (like photosynthesis in plants). One of the main mechanisms of action occurs in the mitochondria (the cellular power plant inside every cell). The effect depend on the application of the correct wavelength and density of light, delivered to the target tissues for an appropriate period of time (typically between 30 – 60 seconds). Pulses can improve tissue repair and anti-inflammatory effect, analgesia is best achieved with a continuous beam.

Low Level Laser Therapy LLLT / Cold Laser Literature watch for Feb 2012

Just 9 papers for you this month including LLLT for orthodontic tooth movement, diabetic periodontitis, ischemic stroke and a laboratory study on chronic mild stress to add to the clinical reports we have seen in recent months.

A plug for the 2012 World Association for Laser Therapy conference in Gold Coast Australia in September. You know you have to go to Australia at some time in your life, well this is that time. Not only does Australia have the most extraordinary wilderness, wildlife and waves of anywhere in the world, it is also the host of this year’s WALT conference. I anticipate that most of the researchers you have read about on this newsletter / blog over recent years will be there . At the WALT 2012 conference in September you can see their latest work and hear their latest thoughts first hand. This land of sun, sea and and so many lasers is probably the most welcoming country i have ever visited, so I suggest you click here to register and click here to book your flights.

The truth will set you free, but you might need a political bulldozer

I love introducing LLLT to an audience of doctors oblivious and innocent of its effects on tissue regeneration, inflammation and pain. At first, the response is that no therapy can do all of this (heal diabetic wounds, improve recovery from sports injuries, neck pain, osteoarthritis and neuropathic pain etc), then I explain the mechanism by which LLLT increases ATP and reduces oxidative stress. By the time I have finished, the final question is not “what is LLLT?” or “how does it work?” or “is there clinical evidence?” but “why is this not used everywhere throughout medicine?”.

The truth is that evidence is not enough. I am involved in the early stages of putting together an international multicentre clinical trial for a pathology that already has 14 RCTs behind it. What difference will one more trial make? The difference may not be the trial itself, but the eminence of the doctors / scientists and their institutions doing it. I am also involved in the early stages of fund raising for another trial that has considerably less clinical data behind it and will be far less ambitious in its scale but, I suspect, will make greater progress. Why ? The focus on political influence. It is not enough to do good science, not enough to address a big unmet need, not enough to influence key opinion leaders, you have got to get the political bulldozers in.

The THOR LLLT Treatment Protocols Library

The Treatment Protocol Library is available only to THOR Customers and/or people who have attended a THOR training course in the last 3 years. All treatments are based on our four step method which includes treatment of the injury, trigger points, lymphatics and nerve roots.

A quick insight into navigating the THOR treatment library, where our customers can learn how to apply our PBM treatments, and download these for future reference.

Many diodes make light work

Having just posted a feature on Prof. Jan Bjordal and the WALT dosage recommendations (read here), I am thinking about dose and cluster probes.

The advice from them is that the correct energy should be applied, that the whole pathology should be treated and, in some cases, there is a power density limit.

At our training course last weekend, someone asked how our LED cluster probe treatment dosage can be compared with the WALT guidelines which are based on single probe treatments. For example, the guidelines for treating a tennis elbow is one or two points, 4 joules per point, max 100mW/cm2.

With our 69 LED cluster probe, for example, the total power applied seems very high (1390 mW). It delivers 4 joules in less than 3 seconds. But this energy is delivered over a very wide area (28 cm2), not over a single point as in the WALT guidelines.

If we divide the 1390 mW power delivered by the area covered of 28 cm2, we get 50mW/cm2. So each cm2 gets 50mW, in which case 4 Joules is achieved at every square cm in 1min 10 seconds. That seems reasonable at first.

We conducted studies on a pig and on a cadaver and found that at 3 cm and 5 cm deep. our 69 LED cluster has the same power density at depth as our 200mW laser which has a surface power density of 5,000mW/cm2. The study showed that light at 50mW/cm2 from the LEDs on the surface scatters and then accumulates at depth to achieve the same density as our single 200mW laser. A 200mW laser delivers 4 joules in 20 seconds but with its surface power density of 5,000mW/cm2, it is considered too strong for treating a tennis elbow (as it exceeds the recommended power density maximum of 100mW/cm2). However, the LED cluster probe has a lower surface power density (so doesn’t exceed the WALT guidelines) but maintains a suitable power density several cm down, to deeper the target tissues.

I think that cluster probes achieve the best of both worlds, they have a lower surface density light than most lasers and yet the same subcutaneous density at depth and over a larger area too, so the whole pathology gets a more even treatment.

I would love you to leave me some feedback. If you use our LED clusters what is your clinical experience? and if you are a physicist what formulas might explain this?

I’m thinking that many diodes make light work, better.
