Therapeutic Ultrasound and Photobiomodulation Applied on the Palm of Hands: A New Treatment for Fibromyalgia?A Man Case Study
摘要： Fibromyalgia is a chronic disorder put in the spotlight in the last decades. Known since the 1920s, the disease is described by multiple painful points, of heightened sensitivity to touch that prevails in women, and afflict 3% to 10% of worldwide population. Fibromyalgia affects skeletal muscles and soft tissues. However, although there is no joint pain. Pharmacological treatment consists in analgesics and anti-inflammatory drugs to ease the pain. In addition, antidepressants, anxiolytics and anticonvulsants can be prescribed to control pain crises. Non-pharmacological approaches as therapeutic ultrasound and photobiomodulation are an alternative for pain relief. Recently, the synergic action of therapeutic ultrasound and photobiomodulation has emerged as an alternative to treat fibromyalgia in women when applied at the palm of hands. The success of the treatment is attributed to stimulation of neuroreceptors close to blood vessels located at the palm of hands and found to be in higher incidence in fibromyalgic patients when compared to healthy patients. This study aimed to evaluate the synergic effect of therapeutic ultrasound and photobiomodulation applied to the palm of hands of a fibromyalgic man patient. Evaluation was based on Quality Life Questionnaire (SF-36) and Visual Analogue Scale (VAS). Results show the treatment could improve the patient’s quality of life (SF-36) and reduce pain (VAS), indicating a new therapeutic approach to treat chronic disorders like fibromyalgia, reducing pain and increasing quality of life of fibromyalgic patients.

A comparative evaluation of the effectiveness of low-level laser therapy, ultrasound therapy, and transcutaneous electric nerve stimulation in the treatment of patients with TMDs: a prospective study
摘要： Introduction A temporomandibular disorder (TMD) is considered to be multifactorial with several treatment modalities available to provide symptomatic relief. The use of non-invasive biological techniques with minimal or no side effects is highly recommended. The present study evaluated the effectiveness of low-level laser therapy (LLLT), therapeutic ultrasound (Th.US), and transcutaneous electric nerve stimulation (TENS) for the management of TMDs. Methodology A total of 45 patients (16 males and 29 females) with an age range between 20 and 50 years having temporomandibular joint (TMJ) disorder with TMJ pain, joint sounds, limited mouth opening, and pain in muscles of mastication were included in the study. The patients were randomly divided into 3 equal groups where group I was given class IV A low-level laser therapy (indium gallium arsenide phosphide [InGaAsP]) at a wavelength of 940 nm biweekly for 4 weeks. Group II was given therapeutic ultrasound in continuous mode at a frequency of 1 MHz and intensity of 1–1.25 W/cm2 for 3 min/session (3 sessions of 3 min each in every visit). The patients in group III were given TENS therapy with low-intensity current for a duration of 30 min, with a pulse rate of 0.11 Hz biweekly. All the patients were followed up twice a week until 1 month corresponding to total eight visits in 4 weeks to check for reduction in pain intensity, number of tender points, joint sounds, and maximal possible mouth opening. Results There was a statistically significant greater reduction in pain (p < 0.005), greater increase in mouth opening (p < 0.005), and more reduction in tender points (p < 0.005) in LLLT group. The significant comparative results could be observed in the first week of therapy itself. The results revealed that LLLT provided most significant symptomatic relief followed by therapeutic ultrasound and least improvement was observed in TENS group. Conclusion Although all the three physical therapies improved the signs and symptoms of TMDs, LLLT was found to be most effective in relieving pain, improving mouth opening, and reducing the number of tender points from the baseline until the end of the treatment compared with therapeutic ultrasound and TENS. Hence, it can be concluded that LLLT is a safe and clinically effective therapy for managing patients with TMJ pain and reduced mouth opening.

Sinergic Effect of Therapeutic Ultrasound and Low-Level Laser Therapy in the Treatment of Hands and Knees Ostheoarthritis
摘要： Osteoarthritis is a degenerative joint disease that affects predominantly hands and knees of the elderly population, being characterized by chronic pain and limitation of joint movements. Therapeutic approaches to ease the pain, as low-intensity pulsed ultrasound and photobiomodulation (low-level laser therapy) have been broadly used as a complement to drug treatment of osteoarthritis. The aim of this study was to evaluate the synergic effect of LIPUS associated to LLLT on osteoarthritis of hands and knees. For this, 69 patients, being 48 affected by knee osteoarthritis and 21 affected by hand osteoarthritis were selected for the study. Patients were evaluated by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for knee osteoarthritis and by Australian Canadian Osteoarthritis Hand (AUSCAN), for hands osteoarthritis. All patients filled out the Visual Analogue Scale (VAS) pain questionnaire, which showed statistical improvement of hands (p<0.001) and knees (p<0.001) when comparing before and after treatment. Functional evaluation by AUSCAN showed improvement of hands functionality (p<0.002). Results showed that the synergic therapy of LIPUS and LLLT were efficient in the treatment of hands and knees osteoarthritis, providing a new approach of a non-pharmacological and non-invasive treatment that contributes to better quality of life for the patients with this chronic and degenerative pathology.

Four-dimensional optoacoustic monitoring of tissue heating with medium intensity focused ultrasound
摘要： Medium-intensity focused ultrasound (MIFU) concerns therapeutic ultrasound interventions aimed at stimulating physiological mechanisms to reinforce healing responses without reaching temperatures that can cause permanent tissue damage. The therapeutic outcome is strongly affected by the temperature distribution in the treated region and its accurate monitoring represents an unmet clinical need. In this work, we investigate on the capacities of four-dimensional optoacoustic tomography to monitor tissue heating with MIFU. Calibration experiments in a tissue-mimicking phantom have confirmed that the optoacoustically-estimated temperature variations accurately match the simultaneously acquired thermocouple readings. The performance of the suggested approach in real tissues was further shown with bovine muscle samples. Volumetric temperature maps were rendered in real time, allowing for dynamic monitoring of the ultrasound focal region, estimation of the peak temperature and the size of the heat-affected volume.
