Efeito do laser vs LED na região do infravermelho próximo sobre a atividade muscular esquelética estudo clínico

Abstract

Resumo Introdução: Estudos têm demonstrado a efetividade do laser no infravermelho (IV) sobre a atividade musculoesquelética. Contudo, não foram observados estudos sobre os efeitos da radiação emitida por um LED (Light Emitting Diode)

Comparative Study of Morphometric and Fourier Transform Infrared Spectroscopy Analyses of the Collagen Fibers in the Repair Process of Cutaneous Lesions

“…Considering the data obtained at this experimental time for the LED group, this result is probably due to the action of phototherapy, making energy available to the cells that were damaged by the surgical process, thus accelerating the repair process during its secondary phase. 20,21,25,43,44 The most significant results were observed with the combination of LED and a semipermeable dressing (LED + D). It is noteworthy that the application of the dressing positively influenced the tissue repair process by accelerating it.…”

“…45 Therefore, these results confirm studies that suggest that US and LED therapies, used individually, increase the formation of collagenous fibers and complete reepithelialization of the injured area. 7,18,20,44 In this study, it was possible to verify that the combination of the semipermeable dressing with LED therapy accelerated the tissue repair process. This would reduce the postsurgical time for healing, which is a very important factor in clinical procedures.…”

Effects of low-level laser therapy (LLLT 808 nm) on lower limb spastic muscle activity in chronic stroke patients

“…However, a later study, conducted with athletes by Maciel et al [49], which applied LLLT (830 nm) in the medial gastrocnemius muscle, showed no significant difference in the increase of the RMS signal (p = 0.1563), the force peak (p = 0.4219), and the onset of muscle fatigue (p = 0.2188). However, Muñoz et al [29] observed that the masseter muscle activity was significantly higher after LLLT (780 nm) (p < 0.05) compared to control values, even without significant differences in the values of strength and fatigue times (p > 0.05).…”

“…Fig. 1 Flowchart of the muscle tissue alterations caused by spasticity and the LLLT effects in the muscle tissue [24][25][26][27][28][29][30][31][32][33][34] Exclusion criteria Presence of hypoesthesia and/or hyperesthesia of the involved lower limb to be studied; presence of active infection and rash at the site of application of the electrodes to be used for electromyography; joint stiffness, contractures, and deformities; Wernicke and Broca's aphasia; uncontrolled hypertension; presence of neoplastic lesions at the site of application; intake of analgesics and/or anti-inflammatory medications during the 2-week evaluation; stroke patients who were on medication containing steroids or steroid medications; and Fitzpatrick Skin Scale type IV and type V. Normally in a clinic situation, patients with darker-pigmented skin can receive the LLLT treatments, but the laser may need to be moved around on the skin, more frequently due to uncomfortable heating [35]. We wanted to keep the laser application method as consistent as possible across all patients; therefore, those patients with darker-pigmented skin were excluded from this research study.…”

Nível de conhecimento sobre Lasers e Leds entre graduandos de Odontologia

“…O que leva aos efeitos biológicos é a quantidade e modo como a energia é entregue, juntamente com o comprimento de onda, sendo que os comprimentos de onda mais utilizados na clínica odontológica se situam na faixa de 600nm a 1000nm, para os Lasers de baixa potência. A bioestimulação promove processos celulares como uma melhor nutrição celular que favorece a regeneração nervosa no caso do tratamento da parestesia oral (Silva Neto et al, 2020, Muñoz et al, 2013Matos et al, 2018).…”
