Analysis of low-level laser transmission at wavelengths 660, 830 and 904 nm in biological tissue samples.

Background: In recent decades, low-level laser therapy (LLLT) has occupied a prominent position and has been studied in various fields of knowledge, and your effects have been widely observed in studies about numerous tissues, such as tendons, peripheral nerves, cutaneous tissue, bone, and muscle, in different fields of knowledge.

Purpose: To analyze the power transmitted by low-level laser therapy (LLLT) to different tissue samples by using distinct wavelengths.

Methods: Skin samples of rat (n = 7, 1.

Red and infrared laser therapy inhibits in vitro growth of major bacterial species that commonly colonize skin ulcers.

Low-level laser therapy (LLLT) is used in chronic wounds due to its healing effects. However, bacterial species may colonize these wounds and the optimal parameters for effective bacterial inhibition are not clear. The aim of this study was to analyze the effect of LLLT on bacterial growth in vitro.

The forearm positioning changes electromyographic activity of upper limb muscles and handgrip strength in the task of pushing a load cart.

The aim of the present study was to analyse the electromyographic activity of the upper limb muscles as well as the handgrip strength during the activity of pushing a load cart. Eighteen healthy male right-handed volunteers (21.50 ± 2.

Blue Laser Inhibits Bacterial Growth of Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.

Objective: The purpose of this study was to analyze the influence of blue laser on bacterial growth of the main species that usually colonize cutaneous ulcers, as well as its effect over time following irradiation.

Background Data: The use of blue laser has been described as an adjuvant therapeutic method to inhibit bacterial growth, but there is no consensus about the best parameters to be used.

Methods: Strains of Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, and Escherichia coli ATCC 25922 were suspended in saline solution at a concentration of 1.

Abdominal muscle strength is related to the quality of life among older adults with lumbar osteoarthritis.

The aim of the present study was to determine the association between abdominal muscle strength and quality of life among older adults with lumbar osteoarthritis. A blind, cross-sectional study was conducted involving 40 older adults: 20 with lumbar osteoarthritis (12 women and 8 men, mean age of 65.90 ± 4.

Polarized currents inhibit in vitro growth of bacteria colonizing cutaneous ulcers.

Infections caused by Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli are among the microorganisms that often lead to infection in pressure ulcers. Polarized current has emerged as a possible intervention to limit bacterial proliferation. We analyzed the effect of fixed diphasic - Bernard (FD-B) and high voltage monophasic pulsed (HVMP) currents on bacteria S.
