Laser therapy is an effective treatment for low back pain. It works by stimulating cells through photons which promotes healing. Key factors for successful laser therapy include sufficient power for deep tissue penetration, proper dosage which depends on factors like wavelength and tissue depth, and an infrared wavelength between 790-970 nm for deeper penetration. Clinical studies show class IV deep tissue lasers providing drug-free and surgery-free pain relief for low back pain.
Chronic pain is the most common cause of long-term disability in the United States. As a result most conditions that result in a visit to physical therapy involve a degree of inflammation and pain. These symptoms typically result in functional limitations, decreased strength and impaired mobility. Physical therapists create treatment plans with efficiency and maximum benefits in mind using a combination of manual therapy, activity-based procedures, patient education and physical modalities. When considering using a modality, many factors are considered: ease of use, efficiency of time, whether it’s non-invasive, and the speed in which it can benefit. Low-Level Laser Therapy (LLLT) is one of the most popular treatment modalities in physical therapy. Physical therapists use laser light therapy to great

effect with a multitude of chronic pain diagnoses including arthritis, neuropathy, muscle strains, fractures, pain reduction and TMJ.
Effective Dosage Utilizing a Therapeutic LaserRob Berman
1) Effective laser therapy requires using a laser with a wavelength between 600-1200 nm and delivering the proper dosage in joules per square centimeter (J/cm2) to the target tissue.
2) The recommended dosage ranges from 0.5-10 J/cm2 but is often quoted as 4-8 J/cm2. However, the authors believe these dosages may be too low based on clinical experience.
3) It is important to have a laser with sufficient power to deliver the necessary joules in a reasonable time, as time efficiency saves costs. Higher power lasers of 100 mW or more can deliver joules of energy much faster than lower power lasers.

Ultrasonic therapy uses high frequency sound waves above the range of human hearing to provide therapeutic effects. It works by using an electrical current to power transducers that convert the current into ultrasonic waves. These waves can then be used for diagnostic imaging, surgery, and physiotherapy. Therapeutically, ultrasonic waves create effects through thermal, mechanical, and chemical/biological interactions with tissues. Common uses are for musculoskeletal conditions like sprains, tendinitis, and arthritis. Proper application involves selecting an appropriate intensity, duration, and frequency setting based on the condition being treated. Risks like burns and tissue damage require precautions like starting with low intensities and using pulsed rather than continuous waves in some cases.

Laser and its use in veterinary practiceManzoor Bhat
Laser technology has various applications in veterinary medicine. Lasers can be used for both therapeutic and surgical purposes. For therapy, low-level lasers are used for pain relief and wound healing through photobiostimulation. For surgery, high-powered lasers allow for precise tissue ablation with less pain, bleeding, and scarring compared to traditional scalpels. The first veterinary laser surgery was a laser-assisted vocal cord procedure in 1964. Lasers continue to provide new capabilities and improvements for veterinary patients.
LASER SURGERY
Class 4 > 500 mW Surgical lasers
Introduction
Surgery using a laser to cut tissue instead of a scalpel
Laser scalpel
Highly focused laser beam efficiently ablates (either vaporize or chip away) the living tissue.
At the same time, it seals (welds) capillaries, small blood vessels, lymphatics, and nerve endings, with significant benefits to both patients and surgeons.
MECHANISM OF ACTION
Photovaporolysis
Char – remnant of non-fluid cellular component.
Photoplasmolysis
Crater
Zone of carbonization- the limit of vaporization
Zone of coagulation and thermal necrosis- Slightly farther away from the center. This zone will eventually die.
Zone of hyperthermia- Farthest from the center. Beyond these zones there is no effect Depth of the crater and the diameter of these zones are directly related to power density.
20-watt Carbon Dioxide laser with plume evacuator
Highly absorbed by water, making it perfect for tissue cutting, vaporization and acoustical destruction.
Thermal injury to surrounding tissue is very superficial.
Lateral thermal injury of 0.05 mm to 0.1 mm
Because there is such minimal lateral thermal damage, injury to surrounding tissues is limited to what you see during application of the laser energy.
General parameters for CO2 laser use
Routine incision: Spot Diameter: 0.4 mm
Power Setting: 6 to 10 W
Routine ablation/vaporization Spot Diameter: 0.8 mm
Power Setting: 10 to 20 W
Delicate location incision: Spot Diameter: 0.3 to 0.4 mm
Power Setting: 3 to 6 W
Routine excision: Spot Diameter: 0.8 mm
Power Setting: 8 to 15 W
LASER USES
Less Pain - The laser seals nerve endings as it cuts. So the patient will have less pain.
Less Bleeding - The laser seals small blood vessels during surgery and speeds up surgery by minimizing bleeding.
Less Swelling - No physical contact except the invisible laser beam. The tissue will not be crushed.
Sterilization - The laser sterilizes the surgical site as it cuts. Bacteria and viruses are vaporized by the laser during laser surgery.
Faster Recovery - Less bleeding and swelling will result in faster healing.
Precision - The beam direction and power can be controlled precisely to remove thin layers of tissue and produce minimal side effects on the surrounding healthy tissue.
Reduced hospitalization time - All above factor will greatly reduce the procedure time.
Laser surgery benefits for surgeons
Unique surgical capabilities: Laser surgery improves many surgical procedures by making them simpler and reducing risk. This enables surgeries that are not practical with conventional methods.
Laser therapy is effective for treating various musculoskeletal conditions like tendinitis and arthritis. Lasers work by emitting coherent, monochromatic beams of light that can be absorbed by tissues to induce physiological effects. Different types of lasers exist like ruby and diode lasers. Treatment involves applying the laser beam to areas like joints for a specified dosage while avoiding eyes and cancers. Studies show lasers can reduce pain and swelling, accelerate wound healing, and improve strength and function for conditions like lateral epicondylitis and rheumatoid arthritis. Precautions must be taken to prevent eye or skin damage from high intensity laser exposure.

The document discusses the history and applications of low-level laser therapy (LLLT). It summarizes three studies that examined the use of LLLT to reduce pain, swelling, and trismus following surgical removal of impacted third molars. The first study applied laser intraorally and extraorally immediately and 24 hours after surgery. It found reduced pain, swelling, and increased interincisal opening with laser. The second study used a zonal laser technique and found reductions in pain and swelling, though not statistically significant. The third study applied intraoral laser once and found significantly reduced pain compared to medication alone. Overall, LLLT shows potential for improving outcomes following third molar surgery, but standardized power settings are needed

This study investigated the effects of infrared laser exposure on cell growth in an in vitro model of wound healing. Fibroblast cell cultures were wounded and then exposed to various doses of 980 nm laser light. Results showed that low and medium intensity laser light significantly accelerated cell growth, while high intensity light negated benefits. Further experiments found cell growth was accelerated over a wide range of exposure durations using medium intensity laser light, with no reduction at longest durations. The study confirms clinical observations that low-level infrared laser exposure can accelerate healing of superficial wounds.
This case report describes the successful treatment of a 47-year-old man suffering from chronic back and leg pain for 10 years using high power laser therapy. Over 10 treatment sessions, the man's pain was reduced by 60-70% and his neurological signs dramatically improved. High power laser therapy stimulates cell metabolism, reduces inflammation, and aids nerve regeneration to provide long-term relief for conditions like radiculopathy. Further research is still needed to better understand the anatomical effects of laser therapy.
This case report describes the successful treatment of an 89-year old female patient's chronic peripheral neuropathy using high power laser therapy (HPLT). Over the course of 15 HPLT treatments administered 3 times per week, the patient's pain was significantly reduced and eventually eliminated. She remained pain-free for nearly a year before symptoms gradually returned, at which point another course of 15 HPLT treatments again eliminated her pain. HPLT was shown to accelerate nerve regeneration and improve blood flow in this patient, providing over 11 months of pain relief, far exceeding other medical treatments she had tried.
The document describes a case study of a 33-year old professional baseball player who sustained a grade 1 ankle sprain. He was treated with a class IV therapeutic laser, Polymem bandage, open basket weave tape, and ice. This new treatment approach reduced pain and swelling, allowing the player to return to play in just 2 days, much faster than the typical recovery time of 1 week. While these new modalities seemed effective in this case, more research is needed to validate their use for ankle sprains.
This case report describes the treatment of a patient with an acute disc herniation at L3/L4 resulting in radiculopathy and foot drop using high power laser therapy. The patient had failed to improve with epidural steroid injections. After 10 treatment sessions over several weeks applying high power laser therapy to the affected areas, the patient's pain and neurological symptoms fully resolved and improvements were still seen over 18 months later without recurrence. High power laser therapy was able to penetrate deeply and stimulate tissue healing, reducing inflammation and promoting nerve regeneration to resolve this patient's disc herniation and associated symptoms.
This case report describes the treatment of a 58-year-old woman suffering from bilateral Achilles tendinitis for 1-2 years. She had not responded to physical therapy or steroid injections. She underwent four treatments with a Class IV infrared laser over each Achilles tendon. This led to a significant reduction in her pain scores on a visual analog scale and an increase in ankle range of motion. The report concludes the laser therapy was effective at decreasing the symptoms of her Achilles tendinitis.

Factors Influencing Reaction Rates:
Concentration of Reactants: Higher concentrations generally increase the rate of reaction.
Temperature: Increasing temperature typically increases reaction rates.
Catalysts: Substances that increase the reaction rate without being consumed in the process.
Physical State of Reactants: The surface area and physical state (solid, liquid, gas) of reactants can affect the reaction rate.
Hepatocarcinoma today between guidelines and medical therapy. The role of sur...Gian Luca Grazi
Today more than ever, hepatocellular carcinoma therapy is experiencing profound and substantial changes.
The association atezolizumab (ATEZO) plus bevacizumab (BEVA) has demonstrated its effectiveness in the post-operative treatment of patients, improving the results that can be achieved with liver resections. This after the failure of the use of sorafenib in the already historic STORM study.
On the other hand, the prognostic classification of BCLC is now widely questioned. It is now well recognized that the indications for surgery for patients with hepatocellular carcinoma are certainly narrow in BCLC and no longer reflect what is common everyday clinical practice.
Today, the concept of multiparametric therapeutic hierarchy, which makes the management of patients with hepatocellular carcinoma much more flexible and allows the best therapy for the individual patient to be identified based on their clinical characteristics, is gaining more and more importance.
The presentation traces these profound changes that are taking place in recent years and offers a modern vision of the management of patients with hepatocellular carcinoma.

Mainstreaming #CleanLanguage in healthcare.pptxJudy Rees
In healthcare, every day, millions of conversations fail. They fail to cover what’s really important, fail to resolve key issues, miss the point and lead to misunderstandings and disagreements.
Clean Language is one approach that can improve things. It’s a set of precise questions – and a way of asking them – which help us all get clear on what matters, what we’d like to have happen, and what’s needed.
Around 1000 people working in healthcare have trained in Clean Language skills over the past 20+ years. People are using what they’ve learnt, in their own spheres, and share anecdotes of significant successes. But the various local initiatives have not scaled, nor connected with each other, and learning has not been widely shared.
This project, which emerged from work done by the NHS England South-West End-Of-Life Network, with help from the Q Community and especially Hesham Abdalla, aims to fix that.

EXPERIMENTAL STUDY DESIGN- RANDOMIZED CONTROLLED TRIALRishank Shahi
Randomized controlled clinical trial is a prospective experimental study.
It essentially involves comparing the outcomes in two groups of patients treated with a test treatment and a control treatment, both groups are followed over the same period of time. Prepare a plan of study or protocol
a. Define clear objectives
b. State the inclusion and exclusion criteria of case
c. Determine the sample size, place and period of study
d. Design of trial (single blind, double blind and triple blind method)
2. Define study population: Most often the patients are chosen from hospital or from the community. For example, for a study for comparison of home and sanatorium treatment, open cases of tuberculosis may be chosen.
3. Selection of participants by defined criteria as per plan:
Selection of participants should be done with precision and should be precisely stated in writing so that it can be replicated by others. For example, out of open cases of tuberculosis those who fulfill criteria for inclusion may be selected (age groups, severity of disease and treatment taken or not, etc.)
Randomization ensures that participants have an equal chance to be assigned to one of two or more groups:
One group gets the most widely accepted treatment (standard treatment/ gold standard)
The other gets the new treatment being tested, which researchers hope and have reason to believe will be better than the standard treatment
Subject variation: First, there may be bias on the part of the participants, who may subjectively feel better or report improvement if they knew they were receiving a new form of treatment.
Observer bias: The investigator measuring the outcome of a therapeutic trial may be influenced if he knows beforehand the particular procedure or therapy to which the patient has been subjected.
Evaluation bias: There may be bias in evaluation - that is, the investigator(Analyzer) may subconsciously give a favorable report of the outcome of the trial.
Co-intervention:
participants use other therapy or change behavior
Study staff, medical providers, family or friends treat participants differently.
Biased outcome ascertainment:
participants may report symptoms or outcomes differently or physicians
Investigators may elicit symptoms or outcomes differently
A technique used to prevent selection bias by concealing the allocation sequence from those assigning participants to intervention groups, until the moment of assignment.
Allocation concealment prevents researchers from influencing which participants are assigned to a given intervention group.
All clinical trials must be approved by Institutional Ethics Committee before initiation
It is mandatory to register clinical trials with Clinical Trials Registry of India
Informed consent from all study participants is mandatory.
A preclinical trial is a stage of research that begins before clinical trials, and during which important feasibility and drug safety data are collected.
Following points high.
3. Avicenna Laser Technology, Inc. was founded in 2002 by Bruce R. Coren, DVM, MS and James Ohneck with the intent to develop a therapeutic laser system capable of delivering healing laser energy to depth’s never before achieved and to offer physician's of all medical disciplines the capability to heal injuries previously refractive to traditional medical care. In December of 2003 Avicenna was granted a 510-k and became the first “Class IV” Therapeutic laser to cleared by the FDA
4. The Avicenna laser was designed from the ground up to be a therapeutic medical laser. It was developed using research by our own biomedical engineers and clinicians as well as collaboration with a major medical school and university optics department. We investigated important criteria such as wavelength, power and power density, optics and beam delivery in order to afford the greatest penetration and delivery of a therapeutic dose capable of stimulating tissue healing in deep seated pathologies. All of our lasers have there own research to support our claims as well as being tested in our patient treatment and R&D center. No other laser manufacturer can make that statement. They typically use studies done with other lasers and then make a great leap of faith to make the claims they do without any of their own research. The world of laser therapy is unfortunately buyer beware!

9. Energy has the capability to penetrate into tissue to varying depths-depending on its corresponding wavelength and power (examples: Electromagnetic spectrum-X-Ray) Surgical Laser Beam- Infrared energy collimated to a fine beam causes tissue destruction Therapeutic Laser Beam- dispersal of same energy causes tissue stimulation
10. Laser therapy aims to bio-stimulate injured and dysfunctional tissues. Clinical studies and trials of Class III & IV laser technology indicate the following beneficial effects of light therapy on tissues and cells.
11. Chromophores are components of molecules which absorb light. The stimulation of chromophores on mitochondrial membranes incites the production of ATP. Leading to a biological cascade of events.
12. Increased Growth factor response within cells and tissue as a result of increased ATP and protein synthesis. Accelerated cell reproduction and growth leading to faster repair of damaged tissues. Increased metabolic activity- via increase in enzyme outputs, oxygen and nutrient availability.
13. Faster Wound Healing- Laser significantly increases fibroblast and collagen production which are essential for tissue repair. Improved Vascular Activity- Increased capillary production leads to faster wound closure. Greater Tensile Strength – Surgical repaired wounds heal with greater tensile strength, including skin, tendon, ligament and fascia. Scar Tissue Reduction- Wounds heal with less scar tissue formation.
15. Anti-inflammatory via an anti-edemic effect as it causes vasodilatation and activation of the lymphatic drainage system.
16. Via increased endorphin release. Anti-inflammatory via less edema as a result of lymphatic system activation and less swelling. Via Suppression of nociceptors.
17. Strengthening the immune system response via increasing levels of lymphocyte activity and through a newly researched mechanism termed photo-modulation of blood. Documented evidence of Tumor size reduction in animals. Mechanism of action unknown.
18. Improved Nerve Function via increased nerve cell reconnections Trigger Point Resolution Acupuncture Point Stimulation Dermatology, Respiratory, GI and OB-GYN cases also being treated by numerous Avicenna clinicians in the field.

20. Safety protocols must ensure sufficient precautions are taken to protect the health and safety of employees and patients .
21. Therapeutic Energy = Measured in Joules Energy Output is based on lasers power output 1 Watt = 1 Joule / Second Laser therapy is a positive form of energy medicine When you treat a patient with a therapeutic laser there is a measurable dosage to every treatment
22. Class IIIa = lasers 1 to 5mw of power (laser pointers) Class IIIb = lasers 6 to 500mw in power (typical cold laser you read about) Class IV = lasers above 500mw of power Avicenna = 12,000mw maximum output
23. Although all therapeutic lasers bio-stimulate tissue, that is where the similarities end. Laser Therapy is all about Physics!
24. As light energy hits the surface of the skin and subsequent deeper layers, some of it is scattered and some of it is absorbed 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
27. 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) In order to overcome those factors one most start with large quantities of energy
28. Prime Determinants of Laser Penetration and Concomitant Tissue Stimulation are: Power – measured in Watts or milliwatts Wavelength – measured in nanometers Power Density – measured in mw / cm2 Frequency – continuous wave versus pulsing
29. Approximately 65% of the energy delivered is lost in the epidermis If you don’t start with enough energy there will not be enough to stimulate cell healing If you do not have sustained power density over a long enough period of time treatments may be ineffective Too much power density can also be detrimental (surgical lasers that have been converted to therapy lasers.) Collimated beam vs. Divergent Beam
30. A laser with two or more wavelengths only has the ability to penetrate as deep as each individual wavelengths allows 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 Continuous wave lasers = 100% duty cycle, laser is always delivering energy which is needed to overcome absorption in the superficial layers
31. In Laser Medicine 1 + 1 Does not = 2 Dual wavelength lasers only penetrate as deep as each wavelength will go individually. The penetration is not additive so there is no real benefit to this scenario. It is more advantageous to have one wavelength of greater power that stimulates cell metabolism and tissue regeneration at all tissues in its pathway. We knew this going into the formation of our laser system unlike our competitors who relied on other laser manufacturers incorrect theory of wavelength and biostimulation.
32. In order to get penetration you must create significant energy density to overcome absorption in the superficial layers of the skin. With low power density and even with pulsed class iv 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. In order to to do so you must saturate the superficial layers of the sponge- with enough water-energy to soak the sponge, so as you pour more water-energy over the sponge it will start to penetrate or leak through. This it what is needed and why it is important to deliver the energy in a continuous manner. Low power or pulsed class iv lasers just cannot provide the energy necessary to overcome the absorptive capabilities of the superficial skin layers and that is why they fail to deliver a positive outcome when trying to reach deep seated pathologies.

35. 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. Pulsing – Lasers that pulse also do not emit continuous energy Avicenna is 100% continuous wave energy

38. Under-dosage – The typical low level or cold laser does not deliver enough energy to adequately stimulate deep seated inflammatory conditions Under penetration - The typical low level or cold laser does not concentrate the laser energy sufficiently to allow for adequate penetration Wrong Diagnosis – This typically occurs when doctors are treating image studies and not the patient. It is paramount that a proper orthopedic and neurologic exam is performed!

Surgical lasers accomplish their objective through excessive heating of tissue are used to cut, coagulate and evaporate tissues. This type of laser replaces the scalpel of the surgeon. There are several advantages to laser surgery. One of the major benefits is that it is often referred to as "bloodless surgery." Laser procedures usually involve less bleeding than conventional surgery. The heat generated by the laser keeps the surgical site free of germs and reduces the risk of infection. Because a smaller incision is required, laser procedures often take less time (and cost less money) than traditional surgery. Sealing off blood vessels and nerves reduces bleeding, swelling, scarring, pain, and the length of the recovery period. Of course laser surgery is not without risk. Like traditional surgery, laser surgery can be complicated by: Hemorrhage Infection Perforation of an organ or tissue. Laser surgery can also involve risks that are not associated with traditional surgical procedures. Being careless or not practicing safe surgical techniques can burn or destroy healthy tissue. Although many laser surgeries can be performed in a doctor's office rather than in a hospital, the person guiding the laser must be at least as thoroughly trained and highly skilled as someone performing the same procedure in a hospital setting.
Therapeutic Lasers are used for the stimulation of cell function. The biological effect is photochemical not thermal, as is the case with surgical lasers.
Compromised cells and tissues respond more readily than healthy cells or tissues to the transfer of energy that occurs between laser therapy emitted photons and the receptive chromophores found in various cells and sub-cellular organelles. Laser energy causes photochemical reactions in the cells. Laser light photons are absorbed by receptors (chromophores) on the mitochondria which are located within the cells. This causes increased production of cellular energy (ATP), which leads to normalization of cell function, pain relief, and healing . The result is that laser therapy has a significant effect on damaged cells and tissues while normative biological constituents are appreciably less effected. A more in-depth explanation regarding the physiological effects of laser therapy will be described in greater detail, later in this presentation.
Develop safety protocols to ensure sufficient precautions are taken to protect the health and safety of all employees and patients .
Each type of tissue has its specific absorption characteristics depending on its specific components (for example, skin is composed of cells, hair follicles, pigment, blood vessels, sweat glands, etc.) The main absorbing structures within tissue are: Hemoglobin in blood Melanin in skin, hair, moles, etc. Water (present in all biological tissue) However a not so well-know fact surrounding laser light is that 5% of all laser energy is absorbed by the skin and subcutaneous tissue. That’s right…. 65% Is it any wonder why low power, Class III lasers, fail to provide the therapeutic energy necessary to stimulate favorable physiological changes on a consistent basis?
Point out that this study was done with OUR laser so we know from this how to establish our protocols, does the competition?
Snapshot in time, when laser is applied clinically its over time so power density and time are both important
This photo demonstrates the ease of specificity with your new Avicenna Laser. Imagine your chances of success treating a tendonopathy with a small diameter beam.
The nice thing about laser therapy is… that it is a modality…. that literally “does it all”. It reduces inflammation, reduces pain, accelerates healing, reduces muscle spasms and trigger points, increases circulation and so on…..plus it has been shown to provide one other characteristic that other modalities don’t do…..does you know what that is? The answer is … Regeneration...it stimulates the proliferation of chondrocytes and osteoblasts. That’s right! Lasers have been shown to reverse inter-articlar loss of cartilage and… accelerate the healing of fractures and bone implants. Additionally, laser has been shown to accelerate the repair of peripheral nerves.
