The Effectiveness of Therapeutic Class IV (10 W) Laser Treatment for Epicondylitis

Abstract

These findings suggest that laser therapy using the 10 W class IV instrument is efficacious for the long-term relief of the symptoms associated with chronic epicondylitis. The potential for a rapidly administered, safe and effective treatment warrants further investigation.

Effects of Gallium Arsenide Laser on Pain and Grip Strength in Patients With Tennis Elbow

“…Many previous researchers conducted their studies on low level laser application with a wavelength of 904 nm and dosage between 2.3 and 4 J/cm 2 [17]. In the present study, the applied wavelength was 980 nm with a dosage of 10 J/cm 2 that increases the level of penetration and energy absorbed density and better effectiveness for laser application.…”

“…Oken et al reported that low level laser with short-term application had no effect in improving pain since the absorbed energy density was not enough, while long-term irradiation would be much more effective on pain reduction or better grip strength [17]. Based on laser theory, effectiveness of laser irradiation depends on the amount of absorbed energy [17].…”

“…Based on laser theory, effectiveness of laser irradiation depends on the amount of absorbed energy [17]. This amount of necessary absorbed energy may increase in a period of time during sessions of application.…”

“…Low level or cold laser therapy with a wavelength of 904 nm has less than 500 mW power and high level laser with similar wavelength has a power higher than 500 mW. The effectiveness penetration depth for high power lasers is about 3 to 4 cm [17]. The laser biological effects depend on three important parameters: wavelength (nm), wave density (j/cm 2 ) and wave intensity (W).…”

Parameter Reproducibility in Photobiomodulation

“…A seemingly reasonable dose may just be the effect of a thin fiber, 2 and a high energy may be dispersed over a large area, thus resulting in a low dose. 3 Qualified readers of an article may be able to calculate what is missing if other parameters such as the spot size (cm 2 ) is reported. However, anyone should be able to have access to all the necessary Tables 1-3 show the work of some fictional authors, Smith et al, who use the tabular method to include necessary detail for their treatment of carpal tunnel syndrome.…”
