BACKGROUND Low-level laser therapy (LLLT) is a conservative treatment for lateral epicondylitis (LE), but it is also an alternative intervention between the very different approaches of Chinese and Western medicine. OBJECTIVE The purpose of this study was to systematically review and meta-analyze the therapeutic effects of LLLT on LE. METHODS We searched several electronic databases, includ...

OBJECTIVE To investigate the effect of therapeutic infrared class 3B laser irradiation on skin temperature in healthy participants of differing skin color, age, and gender. BACKGROUND Little is known about the potential thermal effects of Low Level Laser Therapy (LLLT) irradiation on human skin. METHODS Skin temperature was measured in 40 healthy volunteers with a thermographic camera at la...

OBJECTIVE This study was carried out to investigate the influence of pulsed-wave low-level laser therapy (LLLT) on the healing of a deep second-degree burn model in rat. BACKGROUND DATA Review of literature indicates that LLLT has a biostimulatory effect on wound healing; however, no clear recommendation can yet be made. METHODS Two deep second-degree burns were made in the skin of 67 rats....

BACKGROUND AND PURPOSE Low-level laser therapy (LLLT) modulates various biological processes. In the present study, we assessed the hypothesis that LLLT after induction of stroke may have a beneficial effect on ischemic brain tissue. METHODS Two sets of experiments were performed. Stroke was induced in rats by (1) permanent occlusion of the middle cerebral artery through a craniotomy or (2) i...

BACKGROUND In recent decades, low-level laser therapy (LLLT) has been widely used to relieve pain caused by different musculoskeletal disorders. Though widely used, its reported therapeutic outcomes are varied and conflicting. Results similarly conflict regarding its usage in patients with nonspecific chronic low back pain (NSCLBP). This study investigated the efficacy of low-level laser therap...

[Purpose] The purpose of this study was to investigate the effects of radiofrequency (RF), electroacupuncture (EA), and low-level laser therapy (LLLT), which are used in physical therapies, on facial wrinkles and moisture. [Subjects and Methods] A total of 30 female participants aged 30-55 years participated in this study and the results will be used as a reference for further development of sk...

INTRODUCTION Intestinal ischemia and reperfusion (i-I/R) is an insult associated with acute respiratory distress syndrome (ARDS). Herein we evaluate the dose-response effect of low-level laser therapy (LLLT) on lung inflammation induced by i-I/R. METHODS Mice were subjected to mesenteric artery occlusion (45 min) and killed after clamp release and intestinal reperfusion (2h). Increasing doses...

The inferior alveolar nerve (IAN) is a branch of the trigeminal nerve and this nerve supplies sensation to the ipsilateral lower lip, teeth, and buccal mandibular gingivae. The anatomical position of IAN places this nerve at increased injury risk. During oral surgery, the nerve tissue may be damaged so paresthesia which is characterized by the sensorineural loss that may occur [1,2]. Neurosenso...

Burn scars are known to be difficult to treat because of their tendency to worsen with hypertrophy and contracture. Various experimental and clinical efforts have been made to alleviate their effects but the problem has not been solved. Since patients keep asking for Low Level Laser Therapy (LLLT) and believe in its effectiveness on burn scars, and since former studies show contradictory result...
