Filter by:Hyposalivation is a condition represented by a reduced salivary flow and may include symptoms such as mouth dryness (xerostomia), pain, loss of taste,dysphagia, and dysphonia, all of which greatly affect an individual's quality of life. The aim of the present study was analized the effects of low-level light therapy irradiation (photobiomodulation PBM) on salivary gland function in patients with hyposalivation
Background: Photobiomodulation therapy (PBMT) has become an adjuvant therapeutic possibility in body remodeling procedures. Although this modality emerged in 1960, there are still few studies that demonstrate the real mechanism of action and possible interaction with subcutaneous fatty tissue. Given this scenario, this study was proposed with the aim of evaluating the effects of PBMT to Light Emitting Diode (LED) associating the red (630 nm) and infrared (850 nm) wavelengths in the subcutaneous fatty tissue. Methods: This is a non-randomized controlled study of comparative intervention that evaluated a sample of subcutaneous fatty tissue from women with grade II obesity. The participants received the LED PBMT treatment with associated red and infrared wavelengths sequentially on the left side of the abdomen and the right side was considered as control, with the collection of biological material performed at the time of bariatric surgery. For histological and immunohistochemical evaluation, Caspase 3, Cleaved Caspase 3, CD68+, HSL and adipophilin markers were used.
The present project aims to investigate the effects of lumbar strengthening training combined with photobiomodulation therapy (PBMT) on functional and psychological aspects in young and older adults with chronic non-specific low back pain. We hypothesized that lumbar strengthening training combined with PBMT should promote greater improvement on functional and psychological variables compared to strengthening training alone (placebo PBMT).
In recent years, photobiomodulation has been studied as a means of increasing muscle performance in athletes and healthy individuals. This is possible due to the physiological changes that photobiomodulation therapy can promote. Moreover, given a large number of existing studies on the subject, some directions for future research have been established. For example, future research was established, the relationship between power and time because with high power, it will achieve the same energy with shorter application times. However, irradiation may not be offered for the minimum recommended time. Therefore, this study aims to compare different powers and, consequently, different application times for muscle performance in healthy individuals. For this, 42 participants will be recruited, males between 18 to 40 years old, without recent musculoskeletal injury or cardiorespiratory problems. The participants will participate in 3 evaluations containing functional and physiological variables and ten training sessions of lower limbs with previous photobiomodulation therapy application, comparing devices with a power of 0.864W and 1.864W. 0.864W and 1.2W. Lower limbs training will be composed of stiff and squat exercises twice a week, for five weeks. In the pre- and post-intervention evaluations, the following parameters will be evaluated isokinetic apparatus, body composition, and functionality of the vertical jump. For data analysis, we will use a normality test to verify the distribution and statistical tests will be used for intra and intra and intergroup comparisons, considering two factors in the comparisons time and group. A significance level of 5% will be adopted.
