The story of how LLLT / Photobiomodulation was discovered

This is an extraordinary lecture. It is the story of how LLLT / Photobiomodulation was discovered, and because of the context in which it occurred you might also find it very moving, so get some tissues. It is an hour and 10 minutes long so get comfortable, maybe get some popcorn and a drink too. I will paste the email that Andrew Mester wrote into the comments section below.

Here is the email from Andrew Mester :

I had the privilege to give a keynote presentation at the most recent NAALT (North American Association of PhotobiomoduLation Therapy) meeting in February 5, 2017 in Coronado Island, San Diego. The title of paper was: “Invention of Laser Biostimulation”. My lecture is in Youtube now.

BACKGROUND:
Photo-medicine is an exciting new field in both scientific and clinical research all over the world and most recently in the USA. I learned in this interesting … Continue reading

Class IV laser dose concern. An update from Prof. Jan Bjordal. World Association for Laser Therapy (WALT)

The title of last months PMLS editorial was Low Level Laser Therapy (LLLT) and World Association for Laser Therapy (WALT) Dosage Recommendations. Written by the Scientific Secretary Prof. Jan Bjordal. He describes how far we have come and the importance of the WALT dosage recommendations. No abstract is available for editorials so I have prepared one for you below.

LLLT for Multiple sclerosis (MS) : Nice work Jeri-Anne, Janis and Chukuka

Original article  from http://www.sciencecodex.com/light_as_medicine-121445

Multiple sclerosis (MS) causes progressive paralysis by destroying nerve cells and the spinal cord. It interrupts vision, balance and even thinking.

On a suggestion from a colleague, Jeri-Anne Lyons decided to test how the disease responded to a radical therapy – exposure to a certain wavelength of light called near-infrared (NIR).

THOR at Harvard MIT

David Sengeh has been developing powered limbs at MIT for amputees (like the bionic man). Where the powered limb attaches to the body (the stump of the original leg) it gets very sore. David has been using our standard THOR products to heal the stump and reduce pain. It works very well, though it takes a lot of time to treat the whole area. I am in Boston now to help David start clinical trials with a new device we designed that will treat the whole stump. The amputee puts the the leg stump into the LED treatment cylinder and gets a complete treatment in just one minute :-)

How THOR pulses affect dose (they dont)

THOR laser and LED treatment probes always give the same average power regardless if pulsed or continuous.

THOR pulses are not a fixed pulse width, the pulses are always 88% on 12% off so no matter what pulse frequency is used the the average power remains the same, even when compared with continuous.

This is because we increase the peak power in pulsed mode to compensate for the period when the beam is off.

At say 2.5Hz the THOR pulse width is calculated  0.88 / 2.5  = 0.352 seconds (352ms)

At say 10Hz the THOR pulse width is calculated 0.88 / 10 = 0.088 seconds (88ms)

At say 100Hz the THOR pulse width is calculated 0.88 / 100 = 0.0088 seconds (8.8ms)

Cougar treated with THOR Low Level Laser Therapy (LLLT) by exotic animal veterinarian Jenny Conrad

The picture below is of a cougar treated by exotic animal veterinarian Jenny Conrad. She reports that “Pirate had a seizure of unknown origin and fell off his perch. He’s not usually this approachable but he seemed to like his LLLT treatment and let us work on him for about an hour. He purred the whole time. He seems to be feeling better this afternoon”.

In Memoriam Professor Isaac Kaplan: 1919 – 2012

Isaac Kaplan was not an LLLT guru but the first surgical laser pioneer. As you will see below he was a tremendous figure, well known and much loved. I will leave it to Glen to tell his story but will add one anecdote of my own which Isaac told me:

Many decades ago Isaac was the guest of honour at a dinner in China where upon he alone was served a grand imperial treat called Emperors Soup. The hosts and other guests gathered around to watch in awe as he enjoyed this great delicacy. As Isaac gazed into his soup he saw something moving. Nervously, he picked up his spoon and, bringing the offending creature to the surface, wondered if he should call the waiter to complain. But, as he looked around, he saw the faces of his audience full of delight and encouragement, fervently hoping he would enjoy the wriggling delicacies. He dutifully ate them, attempting to show his enjoyment. Later, he eventually summoned up the courage to ask what he had consumed. It turned … Continue reading
