Effectiveness of interferential current in patients with chronic non-specific low back pain: a systematic review with meta-analysis.

Background: There is no systematic review assessing the effectiveness of interferential current (IC) in patients with low back pain.

Objective: To investigate the effectiveness of IC in patients with chronic non-specific low back pain.

Methods: The databases PUBMED, EMBASE, PEDro, Cochrane Library, CINAHL, and SCIELO were searched.

Chemical seed treatment and mycorrhizal inoculation provide better development and nutrition of common bean plants.

Background: Chemical seed treatment is an established practice in agriculture to protect crops from soil-borne pathogens and pests. Arbuscular mycorrhizal fungi (AMF) benefit plants by extending soil exploration as well as water and nutrient uptake. The objective of this work was to analyze the effects of combinations of seed treatments with doses of inoculant containing Rhizoglomus intraradices on vegetative development, root colonization and nutrition of Phaseolus vulgaris plants and soil microbiota.

Central sensitization and changes in conditioned pain modulation in people with chronic nonspecific low back pain: a case-control study.

Quantitative sensory testing is widely used in human research to investigate the state of the peripheral and central nervous system contributions in pain processing. It is a valuable tool to help identify central sensitization and may be important in the treatment of low back pain. The aim of this study was to evaluate changes in local and segmental hypersensitivity and endogenous pain inhibition in people with chronic nonspecific low back pain.

The effect of burst-duty-cycle parameters of medium-frequency alternating current on maximum electrically induced torque of the quadriceps femoris, discomfort, and tolerated current amplitude in professional soccer players.

Study Design: Repeated-measures, within-subject crossover trial.

Objectives: The primary objective was to assess the effect of the burst-duty-cycle parameters of medium-frequency alternating current on the maximum electrically induced torque of the quadriceps femoris. The secondary objectives were to evaluate the amount of discomfort tolerated and the maximum current amplitude delivered for each electrical-stimulation condition.

Effects of the carrier frequency of interferential current on pain modulation in patients with chronic nonspecific low back pain: a protocol of a randomised controlled trial.

Background: Low back pain is an important public health problem that is associated with poor quality of life and disability. Among the electrophysical treatments, interferential current (IFC) has not been studied in patients with low back pain in a high-quality randomised controlled trial examining not only pain, but pain mechanisms and function.

Methods/design: A three-arm randomised controlled trial with patient and assessor blinded to the group allocation.

Capsaicin on the viability of random-pattern skin flaps in rats.

Purpose: To evaluate the effects of capsaicin on the viability of ischemic random-pattern skin flaps in rats.

Methods: Forty EPM1-Wistar rats were randomized into two groups of 20 animals each, the capsaicin group and the control group. A random-pattern skin flap measuring 10 x 4 cm was raised and a plastic barrier was placed between the flap and the donor site.
