True, DC Blue Print • • • • Find the cause Explain the source Determine effective treatment Shorten treatment time What Happens to Movement After Injury? • What is it about pain that changes the way people move? Or • What is it about the way that people move that causes pain? What Comes First? Injury Pain Altered Motor Control We should diagnose this FUNDAMENTAL QUESTION? For Your Pain “Immediate pain reduction can be achieved by altering muscle activation and movement patterns” Spine, 8-6-2012. S. McGill, D. Ikede Movement, Not Muscles Don’t add strength to dysfunction Movement Comes First If movement is dysfunctional, all things built on that dysfunction might be flawed The Search Is On Laser Focus • Laser: Light Amplification by Stimulated Emission of Radiation • A focused beam of light that emits photon energy • All photons travelling same direction at same wavelength = coherent light Laser Focus “The cell is a machine driven by energy…in every medical tradition before ours, healing was accomplished by moving energy”. Albert von Szent-Gyorgi, 1967 How Does it work? Well, the answer is best explained using the basic principles of photochemistry. A single photon can trigger a reaction in one cell that causes the emission of several photons. These then trigger photon emissions in other cells, and the effect spreads from cell to cell to cell like a chain reaction. These are called high-speed branched-chain processes. How It Works • Increase cellular regeneration (this involves the physiology of cell metabolism, the mitochondria and the synthesis of ATP) • Increase cellular communication (this involves the nervous system, phospholipid cell membrane and the integrin system) How It Works • LLLT stimulates cell activation processes which, in turn, intensifies physiologic activity • Healing is essentially a cellular process • Light energy initiates a cascade of reactions • From cell membrane – cytoplasm – nucleus – DNA • Cellular amplification Wavelengths • Expressed in terms of color. Each wavelength has different properties: – 635 NM wavelengths is the frequency of a healthy cell – 635 NM is the absorbable dose, e.g. WholeFood supplement vs. Centrum or One-A-Day – 20 times more effective than longer wavelengths Why? • Wavelengths between 400 to 660 NM have sufficient energy to displace electrons in atoms to a higher energy level • This is desirable – the higher energy level electron is now more available for donation, expediting the efficiency of all human physiological processes Why? (cont’d) • Longer wavelengths (above 660 NM) penetrate deeper, but at a cost of reduced electron volt ability to displace electrons to a higher energy state. Just because there is deeper penetration does not mean that it excites electrons to higher energy level better Power and Wavelength • LLLT accelerates tension healing, increasing fibroblast proliferation and collagen synthesis • LLLT effective at reducing post-injury inflammation and accelerated soft-tissue healing • LLLT increases ATP…stimulating DNA synthesis and cell proliferation • 632.5-nm laser “produced a higher deposition of collagen, increasing the tensile strength of completely severed and surgically repaired rat tendons Comparative Study Using 685-nm & 830-nm Lasers in the Tissue Repair of Tenotomized Tendons in the Mouse, Photomedicine and Laser Surgery, Dec. 2006, vol.24(6), p.754-758 The efficacy of low power lasers in tissue repair and pain control: a meta-analysis study.

Frequency • Frequency is the blinking quality of the red line • Frequency (in Hz) – the number of light flashes per second. Allows for modulation of the light which can overcome clinical plateaus in patients • Frequency of 30 or less is visible to the naked eye • Over 30 – the pulse/blink is too fast to see and it appears as a continuous line Practice Management Tip • When using laser – remember patients are unable to “feel” the laser • Laser increases cellular regeneration • Laser increases cellular communication Dr. Rob’s Fab 5 Joint dysfunction EC Matrix Exercise/ergonomics/proprioception Laser therapy Nutrition: a) Diet b) Supplements Laser/Pain Management Dr. Rob’s take: • By applying laser energy to affected areas, the frequency sensory nerve firing is increased, which subsequently increases the frequency of stimuli to the spinal cord, brainstem, and brain, in turn inhibiting pain at the spinal cord and brain stem levels Don’t you need a lot of power for the light to penetrate? Too much power – not low-level laser Arndt-Schulz Law • “Weak stimuli excite physiological activity, moderately strong ones favor it, strong ones retard it, and very strong ones arrest it.” • Biomodulation Restoring the cell back to its natural frequency Connective Tissue: A body-wide signaling network?

The low-level laser therapy application improves the healing process of the Achilles tendon of rats Conclusion: the laser treatment is effective during the healing process in tendons since there is more presence of gags and collagen types I and III in tendons submitted to low-level laser than in tendons without treatment. With respect to the active isoform of MMP2, the low-level laser with a pulsed emission is more effective than low-level laser continuous 2012 Fascial congress abstract.

Choosing Your Next Laser • Regulating considerations – FDA-cleared • Therapeutic factor – laser light parameters: – – – – Dose and frequency Wavelength Power Modulation (pulsing) of light • Non-therapeutic factors: – Portability – Size and weight – Corded or cordless operation How does laser compare to other modalities? • Research – ultrasound has value, but laser has been shown to close wounds more effectively • Ultrasound tends to cause slight retraction of hard and soft tissues, laser causes proliferation of these tissues 1) Denir H, 2004.

Photomed laser surg, Dec:24(6) 735-40 What does the low-level laser do • Laser therapy – stimulates both the nervous system and site of tissue injury • Clinically proven to: – – – – suppress inflammation Increase oxygen and blood flow Promote muscle calcium update Increase neurotransmitter release • Key – by addressing the injury with a diverse tool it is possible to resolve the condition more effectively by suppressing not one but all contributors How does laser therapy strengthen muscle? • By delivering specific parameters of light that can increase ATP production, promote calcium influx, and support proper nervous system function and neurotransmitter release WOW • Muscle contraction requires acetylcholine • Acetylcholine causes an electric impulse • Impulse releases Calcium from sarcoplasmic reticulum (inactive form)to the sacroplasm • ATP causes stronger contraction WOW (cont’d) • Stop contraction • Calcium goes from sacroplasm sarcoplasmic reticulum • More ATP the better the relaxation • ATP is required for contraction and relaxation of the muscle • LLLT quickly and efficiently increases levels of ATP How can low-level laser therapy penetrate through clothing? • Low-level laser emits approximately 45 BN photons every second • Clothing material will demonstrate some degree of photon inhibition – the reaction at the cellular level is a 1-to-1 reaction • This requires 1 photon to excrete 1 electron positioned with the photoreceptor Why can’t I feel anything during treatment? • LLLT does not deliver significant amount of energy therefore no friction-like reaction occurs which produces heat • The type of energy delivered does not vibrate or oscillate the cell, therefore no photo-acoustic sensation is experienced How can a response be produced in a matter of a few seconds • Since low-level therapy is responsible for modulating the energy state in which electrons reside, an immediate increase in the rate at which the photo receptor functions coupled with an alleviation in energy production is observed Why the Erchonia PL5A Laser? Increases ATP and decreases free radicals Reduces pain and fibrosis; speeds tissue repair, improves strength and ROM’s; turns on inhibited muscles; synchronizes muscle coordination Why the Erchonia PL5A Laser?
