“…Another non-invasive therapeutical modality that has been used for several years in the control of pain is laser therapy. Its anti-in lammatory effect is pointed out in several studies [1,11,12]. However, in this case study where the therapy used was conjugated, VAS presented a percentage decrease of -716.66% in relation to pain perception.…”

Osteoarthritis of the hand is a chronic condition that involves hand joints, but receives less attention. Few studies have investigated the use of ultrasound therapy and laser therapy for the treatment of hand osteoarthritis. The objective was to evaluate the effect of the conjugated treatment of therapeutic ultrasound and laser therapy on the pain and joint function of a patient with hand osteoarthritis. The is case of a woman, 57 years old, with a diagnosis of osteoarthritis on hand for 3 years, presenting constant pain and worsening after manual activities. The pain and function were evaluated, respectively, by Visual Analog Scale (VAS) and Australian Canadian Osteoarthritis Hand Index questionnaire (AUSCAN). After 12 sessions using ultrasound and laser therapy application, there was an expressive improvement in the pain and functional indexes of the patient. The combined application of therapeutic ultrasound and laser therapy, through the unifi ed fi eld action of the therapies used, proved to be effi cient in reducing pain and improving the functionality.

“…In like fashion the LLLT alone modulates pain and its antiinflammatory effect has been investigated in some studies [7,9]. Even though, the effect of these two modalities acting concomitantly has not been studied before, being a precursor of an innovative equipment.…”

“…Similarly, laser therapy has been used to modulate pain. The studies are based on the anti-inflammatory effect of light as an explanation for the improvement of pain [7][8][9]. In this Context, the uses of technology as therapy excellent option of treatment propose in reason of necessity of decrease of medicine intake.…”

Osteoarthritis of the knee (KOA) is a chronic degenerative musculoskeletal disease associated with functional disability and chronic pain. Currently, physical modalities, such as ultrasound and Laser therapies, are usually prescribed in rehabilitation scenarios as an adjunctive treatment of symptomatic KOA. These therapies have demonstrated great potential to reduce pain and improve the functional capacity of patients with this disease.Thus, the purpose of this case report was to show the effects of prototype equipment specially developed to perform the combined application of therapeutic ultrasound and laser therapy in the symptoms of knee osteoarthritis.The present case reports the use of a prototype of equipment developed to perform the combined application of ultrasound and laser therapy. A 63-year-old woman with KOA for 12 years with painful complaints and worsening of functional capacity was submitted to 12 sessions using the prototype. After treatment, she observed a 95% reduction in pain and a decrease in the WOMAC questionnaire indexes related to pain, morning stiffness, and disability. In addition, to a 50% improvement in the sit and put test.Like this, a single case study shows the efficacy of the combined US and laser therapy on pain and function in the treatment of the symptomatic KOA. The results analyzed, as well as the patient's report make it possible to show the effectiveness in the conjugated treatment and the new equipment.

“…Energy density was in the range from 0.9 J/cm² to 105 J/cm², power density ranged from 9.8 mW to 500 mW, wavelengths contained in the range from 632.8 nm up to 904 nm. Jang and Lee [32] in a meta-analysis of pain relief effects by laser irradiation on joint areas enclosed 22 clinical trials with over 1000 patients involved. The scope of the diseases from which patients suffered in this meta-analysis had a wide spectrum including: rheumatoid arthritis, osteoarthritis, TMD, low back pain, shoulder pain, neck pain.…”

Laser radiation has specific attributes: monochromaticity, high coherence and polarization. These properties result in the extensive use of lasers in medicine. Laser devices can be assigned into three basic groups by means of their level of energy: high, medium and low energy. All of these types of radiation are used in medicine. However, the most commonly used, in basic science and clinical studies, is low-energy radiation. Molecular effects of low energy laser irradiation on cells are generally described as "fotobiostimulation" and "fotobiomodulation". These phenomena consequently lead to attempts to exploit this kind of radiation as a treatment method (low-level laser therapy-LLLT). Areas in which LLLT is used are: regenerative medicine (for healing wounds and ulcers); aesthetic medicine (to improve appearance of scars); dentistry (to accelerate healing of implants); physiotherapy (to reduce chronic pain syndromes), orthopedics (in bone healing) and cardiology (as a prevention of restenosis after percutaneous coronary intervention). This paper discusses the medical applications of LLLT which are used in daily clinical practice as well as those The laser was invented by Theodor Maiman in 1960 and since that time it is used in many different aspects of human life, including medicine. Lasers are distinguished from other light sources by their coherence, polarization and monochromaticity; therefore, they can transmit a wide range of energy.The physical process enabling the laser to function is called stimulated emission (laser is an acronym of light amplification by stimulated emission of radiation). There are many ways to classify laser devices. Lasers can be grouped by gain medium, wavelengths, modes of operation but the most useful way, from a medical point of view, is the division by energy level. And so by the amount of energy transmitted, the sources of laser radiation are divided into 3 basic groups: low, medium and high energy.There are many reports regarding the usefulness of full laser energy spectrum in clinical practice. High-energy radiation causes tissue destruction and therefore it is mainly applied in surgery. It is used for coagulation, cutting tissue, control of bleeding, destruction of tumors etc. Medium energy lasers are mainly used in oncology, especially as a part of photodynamic therapy. The low energy laser, among the all energy radiation groups, seems to have the widest range of applications in medicine. Despite much research, the exact mechanism action of low energy laser radiation on the human body is still unknown. Due to numerous studies on low-energy radiation, new therapeutic applications are being discovered and enrolled to clinical practice. The aim of this paper is to review the most common clinical applications of low-energy lasers.
