HDLT-HPLT High Dose – High Power Laser Therapy
  • HPLTwas first introduced to the medical field in 2002 by then CEO of Avicenna Laser Technology, Inc, Bruce R. Coren, DVM, MS.
  • The company invented and developed the first High Power Therapeutic Laser to receive FDA clearance in 2003.
slide3
TMA– Technological Medical Advancements is a spin off from Avicenna and was founded not only to advance the field of Laser Medicine but also to bring other innovative medical devices to the market place.
  • TMAoffers the most powerful laser platforms in the world and thus allowing physician\'s of all medical disciplines the capability to heal injuries previously refractive to traditional medical care.
design of the tma laser
Design of the TMA Laser
  • The TMA laser was designed from the ground up to be a therapeutic medical laser.
slide5
It was developed using researchby our own biomedical engineers and clinicians as well as collaboration with a major medical school and university optics department.
slide6
We investigated important criteria such as wavelength, power and power density, optics and beam deliveryin order to afford the greatest penetration and delivery of a therapeutic dose capable of stimulating tissue healing in deep seated pathologies.

  • Therapeutic Lasers are used for the stimulation of cell function.
  • The biological effect is photochemical not thermal, as is the case with surgical lasers.
comparison of class iv surgical and therapeutic lasers
Comparison of “Class IV” Surgical and Therapeutic Lasers
  • Surgical lasers collimate high amounts of laser energy into a beam of high intensity resulting in tissue destruction
slide13

High Power Therapeutic Lasers take a high amount of laser energy but instead of beam collimation you get beam divergence resulting in tissue stimulation

energy medicine and therapeutic laser physics
Energy Medicine and Therapeutic Laser Physics
  • The therapeutic dosage of laser energy is measured in Joules
  • Dosage is a function of the lasers power output
  • For every one watt of continuous laser power output, one joule of laser energy is delivered per second of time
slide64

For a pulsed laser the energy delivery depends on the duty cycle. Duty cycle tells us what percentage of time the laser is on or actively firing. If the duty cycle is 50% then the laser at 1 watt only delivers 0.5 Joules / Second.

  • For any given time period a continuous wave laser delivers twice as much energy than laser with a 50% duty cycle
laser physics
Laser Physics

The shorter the wavelength, the more readily the energy is absorbed in the body.

The higher the wavelength, the deeper the penetration of photon energy.

absorption curve
Absorption Curve

980 nm: Low melanin, low water, low hemoglobin absorption thus an optimal wavelength to choose when designing a therapy laser for stimulating tissue at greater depths of penetration.

physiological effects light tissue interactions
Physiological Effects Light – Tissue Interactions
  • 65% of laser energy is absorbed in the skin and subcutaneous tissue layers with the following having a high affinity for absorption:
    • Hemoglobin in blood
    • Melanin in skin, hair, moles, etc.
    • Water (present in all biological tissue)
how laser light penetrates tissue
How Laser Light Penetrates Tissue
  • As light energy hits the surface of the skin and subsequent deeper layers, some of it is scattered and some of it is absorbed and some is reflected
  • At each tissue interface less energy is available to pass further through to the next layer because of the effects of absorption, reflectance and transmission
laser penetration
Laser Penetration
  • Laser Energy is just another form of energy on the electromagnetic spectrum.
  • Depth of penetration is determined by wavelength and energy density.
  • Just like with x-rays when deeper penetration is required, more energy must be delivered to reach the target tissues.
clinical therapeutic laser penetration
Clinical Therapeutic Laser Penetration
  • Prime Determinants of Laser Penetration and Concomitant Tissue Stimulation are:
  • Power – measured in Watts or milliwatts
slide72

Wavelength – measured in nanometers

  • Power Density – measured in mw / cm2
  • Frequency – continuous wave versus pulsing
importance of power density
Importance of Power Density
  • Since approximately 65% of the energy delivered is lost in the epidermis
  • If you don’t start with enough energy on the skin, there will not be enough to stimulate cell healing in deeper tissues
slide74

If you do not have sustained power density over a long enough period of time treatments may be ineffective

single wavelength multiple wavelength continuous or p ulsed wave laser
Single Wavelength, Multiple Wavelength,Continuous or Pulsed Wave Laser
  • A laser with two or more wavelengths only has the ability to penetrate as deep as each individual wavelengths allows
  • Most class iv lasers that pulse or have a high duty cycle coupled with multiple wavelengths of energy emission will not penetrate as deep as CW lasers of a single wavelength or lasers that can pulse but still maintain a high average power output
slide76
Continuous wave lasers = 100% duty cycle, laser is always delivering energy which is needed to overcome absorption in the superficial layers
  • Newer generation of TMA lasers can now pulse yet still maintain a high average power output allowing for greater tissue saturation with less thermal effects
slide77

In Laser Medicine 1 + 1 Does Not Equal 2

  • Dual wavelength lasers only penetrate as deep as each wavelength individually. Penetration is not additive. There is no validated clinical benefit to this scenario. It is more of a marketing
slide78

For purposes of penetration it is more advantageous to have one wavelength of greater power that stimulates cell metabolism and tissue regeneration at all tissues densities in its pathway

is there a magical wavelength
Is There A Magical Wavelength?
  • Throughout our 13 years of clinical experience using a 980nm treatment beam, we have experienced stellar results with both superficial and deep pathologies.
  • We still feel once you are treating within the infrared spectrum, power, power density and dosage are the key to better clinical outcomes.
slide80

Sponge Theory

  • In order to achieve penetration one must create significant energy density to overcome absorption in the superficial layers of the skin.
  • With low power or pulsed lasers it is like pouring small amounts of water onto a large sponge (the dermis and subcutaneous tissues) and expecting the water to leak through.
slide81

In order to do so you must saturate the superficial layers of the sponge- with enough water-energy to soak the sponge-superficial tissue structures

  • So as you pour more water-energy over the sponge it will start to penetrate or leak through.
slide82

This it what is needed to penetrate and why it is important to deliver a high amount of laser energy/dosage on the skin

  • Especially if you want to reach deep seated pathologies.

slide85

Translation – As laser light or energy penetrates through the body more and more energy is absorbed so by the time you start reaching deeper structures there is not enough therapeutic energy to cause adequate tissue stimulation

  • Thus the reason why low power lasers as well as pulsing lasers cannot effectively treat deep seated pathologies.
other factors affecting lasers penetration
Other Factors Affecting Lasers Penetration
  • Duty Cycle – 100%
        • Laser is firing continuously
        • Duty Cycle – 50%
  • Laser is firing 50% of the time. This will not only cut energy delivery but it will also affect ability to penetrate.
slide87

Pulsing – Lasers that pulse also do not emit continuous energy

  • Lasers that can operate at 100% continuous wave output or pulse the laser energy while still maintaining a high average power output is key to treating deep seated pathologies and better clinical outcomes.
class iii vs class iv laser beams
Class III vs. “Class IV” Laser Beams

With a high power output the laser beam can easily penetrate deeper joints especially when compared to a class iii laser which at best only offers superficial penetration.

why therapeutic lasers fail
Why Therapeutic Lasers Fail
  • Under penetration - The typical low level or cold laser or weak or pulsed class iv laser does not concentrate the laser energy sufficiently to allow for adequate penetration
slide90
Under-dosage – The typical low level or cold laser or weak or pulsed class iv laser does not deliver enough energy to adequately stimulate deep seated inflammatory conditions
slide91

TMA protocols are successful because they call for delivery of significantly larger amounts of therapeutic energy than industry standard protocols.

tma diowave philosophy
TMA-Diowave Philosophy
  • TMA’s goal has always been to build the most efficacious laser available to deliver the best outcomes.
  • Our lasers are built from the ground up and are designed to get patients who have failed traditional therapy better
slide93

Many other lasers are built based on economic factors or from taking laser from other markets like dentistry and converting them into weak class iv lasers

  • There are no shortcuts to treating deep seated pathologies and one must deliver the correct dosage of laser energy in order to get the best outcomes.
the key to better outcomes
“The Key to Better Outcomes”
  • Higher the power output of laser energy
  • The Greater The Penetration and Dosage
  • The Faster the Therapeutic Outcome
slide95

The Quicker the Patient Returns to Normal

  • This is the main reasons we keep advancing our technology and developing more powerful lasers.
why more power is better
Why More Power is Better
  • More power equates to deeper penetration, faster delivery of the proper therapeutic dosage, and ultimately better outcomes
  • A 30 watt laser will not only penetrate deeper, it will put more therapeutic energy to the target pathology
  • It will do this 3X faster than a 10 watt laser and 5X faster than a 12 watt laser with a duty cycle of 50%
recommendations for high dose laser therapy
Recommendations for High Dose Laser Therapy
  • Small Joint – 25-50 lb. Pet = 6,000 Joules
  • Small Joint – 50-100 lb. Pet = 9,000 Joules
  • Large Joint - 25-50 lb. Pet = 9,000 Joules

PHYSICAL PARAMETERS OF

SOME COMMON CLASS IV LASERS

slide102

MDO = Maximum Diode Output

  • Duty Cycle = Average Time Diodes Are Firing
  • MPTD = Maximum Penetrating Therapeutic Dosage.
slide103

Because wavelength and power determine

penetration, and each wavelength penetrates

independently, the maximum penetrating dose

is no greater than the maximum power output

of each diode. With a 50% duty cycle

penetration of each diode gets cut in half.

4. JPM = Joules Per Minute

5. CPW = Cost Per Watt

(Continuous Power Output)

slide104

Maximum power output per wavelength is one of the most important factors in favorable treatment outcome.

  • With a dual wavelength laser, laser beam penetration is reduced by 50%; with a 50% duty cycle setting and dual wavelengths, laser penetration is equal ¼ of the stated power output of the laser.
slide105

With multiple-wavelength lasers (2-3) beam penetration is reduced even more significantly. If a 50% duty cycle setting is paired with a three-wavelength laser, beam penetration is equal to 1/6 of the stated laser power output.

  • A 10W CW Diowave laser has a stronger maximum diode power output of any therapy laser currently produced.
