Akbari A1 1. Assistant Professor, Department of Physiotherapy, Faculty of Medicine, Zahedan University of Medical Sciences Abstract Background: Shoulder pain is the third most prevalent cause of musculoskeletal disorder after low back and cervical pains. Most of the shoulder symptoms are attributed to the rotator cuff. The objective of this study was to compare the effects of low-power ...

o bjectives: one major drawback of orthodontic treatment is its long duration due to slow tooth movement and the pain at the onset of treatment following application of forces. there is controversy regarding the efficacy of laser for decreasing the treatment time and pain of orthodontic treatment. the purpose of this study was to investigate the effect of low level diode laser on the rate of or...

introduction: low level laser therapy (lllt) also known as photobiomodulation, is a treatment that uses low-level lasers or light-emitting diodes (leds) to change cellular function and is a clinically well accepted tool in regenerative medicine and dentistry. considering the variety of laser, exposure, cells and study types, the exact effects of low level laser therapy seems to be unclear. the ...

introduction: tooth pain and sensitization are the two main causes of discomfort after periodontal flap surgery. effects of low level laser therapy for reducing pain have already been established; these kinds of lasers have been used for tooth desensitization as well. this controlled blind study sought to compare tooth pain and sensitization after 660nm laser irradiation in a split mouth and al...

The laser flare intensity in diabetics, measured with the scattering of a light beam, was evaluated and compared with actual aqueous protein concentration obtained during surgery. Measurement of the laser flare intensity in 120 diabetics and 108 normal subjects was performed with the laser flare cell meter (FC1000 Kowa, Tokyo). Aqueous protein concentration in 26 diabetics and six controls who ...

Measurement of laser intensity inside a femtosecond laser filament is a challenging task. In this work, we suggest a simple way to characterize laser peak intensity inside the filament in air. It is based on the signal ratio measurement of two nitrogen fluorescence lines, namely, 391 nm and 337 nm. Because of distinct excitation mechanisms, the signals of the two fluorescence lines increase wit...

introduction: an attack of acute myocardial infarction (mi) poses the threat of great damage to cardiac tissue. operative therapeutic modalities such as coronary artery bypass grafting (cabg) may enhance myocardial perfusion in high-grade coronary vasculature occlusions. it has been shown previously that low-level laser therapy (lllt) significantly reduces infarct size following induction of my...

low-power lasers are a group of lasers with a power less than 500 mw and unlike high-power lasers they have no effect on tissue temperature; they produce light-dependent chemical reactions in tissues. the purpose of this study was to review the clinical applications of these lasers and their success rate in different studies in orofacial pains. the articles with the key word “low level laser th...

[Purpose] This study examined the effects of High Intensity Laser Therapy on pain and function of patients with chronic back pain. [Subjects and Methods] This study evenly divided a total of 20 patients with chronic back pain into a conservative physical therapy group that received conservative physical therapy, and a high intensity laser therapy group that received High Intensity Laser Therapy...
