What is high power laser therapy?
High Power Laser Therapy uses laser radiation in the 800 to 1100 nm wavelength range. Wavelengths: 808/810 nm and 980 nm are particularly popular, of which the first wavelength is the source of the biostimulation effect, and the second leads to a local increase in tissue temperature. 2W was used as the limit power value above which we can talk about high power laser therapy. The use of a high power laser can lead to a local increase in tissue temperature not exceeding 42 degrees C.
The 808 / 810nm wavelength is strongly absorbed by the cytochromes contained in the mitochondria of each cell. This activates the respiratory chain and initiates processes that increase ATP production. Furthermore, laser light affects the stimulation of enzyme synthesis, which is associated with obtaining biostimulation effects.
The 980nm wavelength, for a change, is strongly absorbed by water, which causes a rise in tissue temperature. Thanks to this, an increase in metabolism, an increase in the collagen fiber stretch, an increase in the permeability of biological membranes and an analgesic effect is achieved. Thanks to these phenomena, applying the laser beam in the place of disease occurrence allows not only for biostimulation of the designated area of the body but also to obtain a noticeable improvement without the need for more invasive treatment methods. For 808 / 810nm wavelength there is observed deep penetration, reaching up to 5cm. The 980nm wavelength, due to its strong absorption by water, penetrates much shallower. Tests and measurements show that the transmission factor for the wavelength of 810nm is 25 times higher than for 980nm. Both of these wavelengths are outside the visible range.
Therefore, high power lasers use a visible pilot beam, usually in red colour. A high power laser has a wide impact on the body’s processes. Its use enables the stimulation of DNA synthesis, an increase in the fibroblasts activity (among others, they are involved in the healing process, increase cartilage compressibility, produce collagen), and phagocytosis activation.
How does high power laser therapy
help patients?
The effectiveness of treatment of diseases using high power laser therapy has been proved by research. The laser is currently used in the treatment of diseases in the field of general medicine, dermatology, ENT, dentistry, neurology, orthopaedics, podology, surgery, rheumatology and even oncology. It also supports rehabilitation, physiotherapy and sports medicine, helping to reduce the effects of injuries and damages to the tendon and bone.
Laser therapy helps in the treatment of diseases located in almost every area of the patient’s body with a particular focus on the treatment of persistent, severe pain, wound healing, anti-inflammatory and anti-edema effects. This type of therapy allows not only to alleviate the symptoms connected with pathological changes in tissues but also to effectively treat their causes.
The use of high power laser therapy.
What diseases does it cure?
High power laser therapy supports the healing and regeneration of tissues, activates the metabolic processes of cells and accelerates microcirculation. It works equally well in the case of myalgia as well as in the treatment of damaged or irritated nerves connected with the occurrence of acute, radiating pain. High power laser therapy is used to treat, among others such diseases as:
sore tendon heels – Achillodynia
plantar fasciitis
joint sprain, hallux
arthritis, bursitis
meniscus damage
cervical discopathy, cervical radiculopathy
calcaneal spur
Intercostal neuralgia, trigeminal neuralgia
bruises, ligament/tendon rupture
chondromalacia patellae
lumbago – lower back pain
sciatica – ischialgia
tarsal tunnel syndrome, degeneration of joints
The positive effects of laser therapy are visible after a few treatments depending on the treatment parameters and frequency.
High power laser in physiotherapy centers
Laser therapy devices allow the use of radiation sources in pulse or continuous mode, and their power is many times greater than the power available only for biostimulation lasers. Devices enabling the use of a treatment encyclopaedia (e.g. Polaris HP) allow for comfortable conducting of therapy. The use of tested procedures significantly reduces the possibility of incorrect selection of parameters.
Astar has also developed a technology that increases the precision and effectiveness of therapy while limiting the thermal effect on the skin and subcutaneous tissue. The DILA focusing adapter (Deep Intratissue Laser Adapter) forms a laser beam in a way that reduces power loss in surface tissues, which significantly increases the comfort and effectiveness of the treatment.
Polaris HP S – benefits for the patient
Modern pain therapy
The simultaneous use of two modules with different wavelengths allows to achieve a double therapeutic effect – biostimulation of a selected area of the body and an effective and fast thermal effect at the application site. In this way, Polaris HP S eliminates even severe, chronic pain connected with bone and soft tissue disorders, restoring patients’ comfort of life. High power laser therapy is helpful in the treatment of diseases in the field of, among others, orthopaedics, rheumatology, dermatology, podology, neurology and many more.
Its beneficial effects on tissues have also been appreciated by specialists in the field of veterinary medicine and animal physiotherapy.
Rapid tissue regeneration
Biostimulation in combination with high power laser therapy has a beneficial effect on tissue areas covered by the pathological process. Thanks to its activity, laser therapy increases the body’s tissue regeneration capacity, and by stimulating angiogenesis, the vascularity and nutrition of the affected area also increases. The combination of laser therapy with 808 nm and 980 nm wavelengths has an antimutagenic effect, and also results in an increased synthesis of collagen, proteins, RNA, DNA and ATP, acceleration of electrolyte exchange between the cell and the environment, stimulation of fibroblast activity, greater tissue oxygenation, and activation of phagocytosis (natural protection against pathogens) and a significant reduction in pain by activating the analgesic mechanism according to the gate control theory of pain proposed by Melzack and Wall.
Advanced technology
ASTAR has designed and patented a unique solution enabling therapy on deeper tissue layers. DILA (Deep Intratissue Laser Adapter) is an adapter that, thanks to the use of an advanced optical system, allows the formation of a laser beam focused in the tissue to a depth of several centimetres. The use of this technology means that the thermal effect on the surface of the area in which the laser beams are applied significantly decreases. DILA is an optional accessory of the device.
Benefits for the physiotherapist
Intuitive operation
The device has been designed based on the needs and recommendations of physiotherapy specialists, so that its operation allows for obtaining long-lasting treatment effects. Polaris HP S is equipped with a practical encyclopaedia describing the methodology for performing particular treatment procedure displayed on a large, 7-inch graphic display with a touch panel. The user can choose to work in manual or program mode and select independent settings for both radiation sources. Adapters changing is extremely simple, and the laser application site is indicated by a pilot beam enabling to define precisely the area undergoing therapy. Operation of the device and quick change of treatment parameters is facilitated by a handy knob. High power and biostimulation laser therapy. Polaris HP S is a dual-use device – as a high power and biostimulation laser simultaneously. The controller has two built-in radiation sources (with peak output power up to 18 W in pulse mode). The list of supported applicators includes R and IR point probes, a cluster laser applicator and a scanning laser applicator also available in the ASTAR offer. The use of any of these applicators allows you to conduct biostimulation laser treatments.
Mobile, comfort and safe
Thanks to the Polaris HP S device, it is possible to perform treatments in a physiotherapy center or mobile, in any place chosen by the user. The device is lightweight, weighs only 6 kg, and the ergonomic bag available as an option will fit the device with its equipment. Polaris HP S has a built-in self-test procedure that ensures current control of all device modules each time it is turned on.
Polaris HP S
Polaris HP S allows to perform biostimulation and high power laser therapy. It combines the effects of both therapies enabling maximum effectiveness during treatment. The device has two laser modules with a wavelength of 808 and 980 nm (power of 8 and 10 W) that can work in continuous, pulse or superpulse mode.
Polaris HP S also works with the innovative focusing DILA adapter (Deep Intratissue Laser Adapter), which allows the formation of a laser beam in a way that reduces the occurrence of a thermal effect and compensates for power losses in surface tissues
