The effects of photobiomodulation and transcutaneous electrical nerve stimulation on chronic neck pain: A double-blind, randomized, sham-controlled trial.

Background: Photobiomodulation (PBM) and transcutaneous electrical nerve stimulation (TENS) are used to reduce neck pain.

Objective: To investigate the immediate and 1-month post-treatment effects of 10 treatment sessions of PBM and TENS delivered over 2 weeks on pain intensity in individuals with neck pain.

Methods: Individuals with neck pain were randomized into four groups: PBM+TENS, PBM, TENS, and Sham.

Photobiomodulation therapy and transcutaneous electrical nerve stimulation on chronic neck pain patients: Study protocol clinical trial (SPIRIT Compliant).

Introduction: Chronic neck pain is a common musculoskeletal disorder that is associated with functional disability and decreased of quality of life. Electrophysical agents are commonly used to relieve pain, however the effects of combined use of these agents are little studied. The objective is to investigate the efficacy of photobiomodulation and electrical stimulation to relieve pain, both in isolation and combined.

Segmental and extrasegmental hypoalgesic effects of low-frequency pulsed current and modulated kilohertz-frequency currents in healthy subjects: randomized clinical trial.

: To compare the segmental and extrasegmental hypoalgesic effects of TENS, IFC and Aussie current on pressure pain threshold (PPT) during and after stimulation in healthy subjects. The second objective was to compare the sensory comfort related to electrical stimulation.: 120 healthy subjects were randomized in TENS, IFC, Aussie current or placebo groups.

Effects of red and near-infrared LED light therapy on full-thickness skin graft in rats.

The aim of the present study was to evaluate the in vivo response of different wavelengths (red and near-infrared) of light-emitting diode (LED) on full-thickness skin grafts (FTSG) in rats. Thirty rats were randomly allocated into three experimental groups: control group (C); red LED treated group (R); and near-infrared LED group (NIR). Skin grafts were irradiated daily for ten consecutive days, starting immediately after the surgery using a red (630 nm) or near-infrared (850 nm) LED.

A Comparison of Three Methods for the Analysis of Skin Flap Viability: Reliability and Validity.

Technological advances have provided new alternatives to the analysis of skin flap viability in animal models; however, the interrater validity and reliability of these techniques have yet to be analyzed. The present study aimed to evaluate the interrater validity and reliability of three different methods: weight of paper template (WPT), paper template area (PTA), and photographic analysis. Sixteen male Wistar rats had their cranially based dorsal skin flap elevated.

Study protocol of hypoalgesic effects of low frequency and burst-modulated alternating currents on healthy individuals.

Unlabelled: The aim of the study will be to compare different types of analgesic electrical currents in relation to the pressure pain threshold and sensory comfort in healthy individuals. A total of 100 individuals will be randomly assigned to four groups: transcutaneous electrical nerve stimulation, interferential current, Aussie current or placebo. The electrical stimulation will be administered with a strong level for 30 min and to the placebo group, the electrodes will be positioned while the equipment will remain switched off.

[Evaluation of coronary risk and its relationship to health actions in hypertensive patients].

The risk of developing acute coronary events was evaluated according to Framingham criteria and health actions performed to hypertensive patients at a Health Unit Family of Vitória-ES. This is a observational, cross-sectional study, involving 330 hypertensive. The sample considered a 50% prevalence of the disease.
