Radiotherapy in the head and neck region and chemotherapy might give rise to oral mucositis which is a severe and painful inflammation. There is no known definite cure for mucositis. A number of studies have attempted to evaluate the effect of low-power laser on radiotherapy- and chemotherapy-induced mucositis. The present study was undertaken to evaluate the effect of low-power laser on the pr...

We have developed a linearly-polarized Ytterbium-doped fiber ring laser with single longitudinal-mode output at 1064nm for LISA and other space applications. Single longitudinalmode selection was achieved by using a fiber Bragg grating (FBG) and a fiber Fabry-Perot (FFP). The FFP also serves as a frequency-reference within our ring laser. Our laser exhibits comparable low frequency and intensit...

aim and background:   knee osteoarthritis (oa) is a prevalent and disabling disease. periarticular corticosteroid injection has been traditionally used for the pain control in these patients. recently low power laser has been introduced as a therapeutic option. this study was conducted to evaluate the efficacy of low power laser added to periarticular steroid injection for long-term treatment o...

Background: Acupuncture is an indispensable part of traditional Chinese medicine for relief of pain. The purpose of this study was the immediate & latent of low power LASER Ga-Al-As irradiation applied to acupuncture points on experimental pain threshold. Methods: This quasi-experimental study was conducted on seventy adult women ranging from 20 to 40 years old assigned randomly into two groups...

INTRODUCTION Temporomandibular disorders (TMD) lead to masticatory muscle pain, jaw movement disability and limitation in mouth opening. Pain is the chief complaint in 90% of the TMD patients which leads to disability and severe socioeconomic costs. The purpose of this study was to evaluate the therapeutic effects of low level laser therapy (LLLT) compared to pharmacotherapy with NSAIDs (naprox...

The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS). Thirty BMS subjects were randomized into two groups - Laser (LG) and Placebo (CG). Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG. Each patient received 4 irradiations (laser or placebo) twice a week, for two consecutive weeks (blinded ...

introduction: myofascial pain syndrome (mps) treatment is challenging with a high recurrence rate and still lacks a clear treatment frame. therefore research on new, more efficient and long lasting effect treatment modalities is necessary. this study looked at the effects of intravenous laser therapy (ivl) and percutaneous low level laser (plll) in the management of shoulder mps. methods: in th...

Expectations about the magnitude of impending pain exert a substantial effect on subsequent perception. However, the neural mechanisms that underlie the predictive processes that modulate pain are poorly understood. In a combined behavioral and high-density electrophysiological study we measured anticipatory neural responses to heat stimuli to determine how predictions of pain intensity, and ce...
