“…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.

“…This research study suggests that analgesia associated with LLLT results in the anti-inflammatory properties on the articular capsule as suggested by the World Association of Laser Therapy (WALT), with similar results being produced, resulting in both pain relief and a decrease in knee circumference values. [6,7,8] The main finding of this study is that of an adjunctive effect of LLLT with the conservative exercise management of KOA. The findings showed that the KOA outcomes significantly improved across all three intervention groups (p<0.05), with the LLLT group showing better short-term pain relief, but the combined exercise-LLLT group demonstrated better longterm reduction in pain symptoms.…”

Background: Knee Osteoarthritis (KOA) is a prevalent, chronic disorder with excessive functional, social and economic burdens. The goal of treatment is to alleviate the symptoms and slow the progression. Documenting the effects of exercise and LLLT as co-modalities in the management of KOA allows practitioners to implement this management tool as part of KOA rehabilitation, resulting in the earlier discharge from a supervised rehabilitation setting. Objective: The purpose of this study was to determine the effect of low-level laser therapy (LLLT) in the treatment of knee osteoarthritis (KOA). A randomised controlled trial (RCT) was conducted on 111 participants (aged between 40-75 years) diagnosed with KOA. Participants were randomised into an exercise (n=39), LLLT (n=40), or a combined exercise-LLLT (n=32) group. Methods: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale was used to assess pain and functionality. Knee range of motion was assessed using a goniometer, and the one-minute timed sit–to-stand test measured physical functionality at four time points: (T1) baseline, (T2) post 12-session intervention, (T3) one-month post intervention and (T4) three-month’s post intervention. Knee circumference was measured using a measuring tape. Results: WOMAC pain and functionality scale and knee circumference scores decreased in all three groups (P<0.05), but the combined exercise-LLLT group demonstrated better outcomes than the LLLT or exercise alone groups respectively. The combined exercise-LLLT group showed better acute and long-term benefits with participants experiencing a 3.5 centimetre decrease in knee circumference, 24 point improvement in the WOMAC pain and functionality scale, and a four repetition increase in physical functionality. Conclusion: The findings suggest that LLLT is a viable tool for managing KOA when used in conjunction with physical exercise.

“…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.
