Effects of low-level laser therapy on the healing of foot ulcers in people with diabetes mellitus

Abstract

Objective: Identify the effects of low-level laser therapy on the healing of diabetic foot. Method: Systematic review of the PubMed, LILACS, SciELO, CINAHL, Cochrane, Web of Science and Scopus databases, in which 92 articles were identified and six were included in the final sample after the eligibility criteria. Results: The articles pointed out as effects of laser therapy the effectiveness in the progression of the tissue repair process of the diabetic foot, pain relief, anti-inflammatory action, increased tissue perfusion of the lesion and improvement of the vascular response and the nervous system. Conclusion: Laser is an adjuvant therapy that can accelerate the wound healing process, relieve pain, improve neovascularization, and thus minimize the risk of complications, such as lower limb amputation and improvement of quality of life for people with diabetes and impaired skin integrity.

Photodynamic therapy for infected foot ulcers in people with diabetes mellitus: a systematic review

“…9 However, it is pertinent to discuss the importance of health education with the patients during therapy, especially regarding glycemic control, foot care, use of appropriate shoes, and a healthy lifestyle to improve the success of PDT. 13 The current study contributes to improving the awareness of healthcare professionals regarding new protocols and medical therapies using adjuvant technologies with better cost-ben-…”

“…Although there are favorable reports regarding the application of PDT, 11,12 newer investigations can provide additional evidence about the effectiveness of PDT in the treatment of DFU. 13 A study identified that health professionals, even those with qualifications to operate LASERs, have doubts regarding the dosage, wavelength, time, and number of applications to be used. 14 Therefore, it is important that health professionals, especially wound experts, understand the new approach of PDT in treating infected ulcers and incorporate it into their practice to promote optimized healing and reduce the number of complications due to DFU.…”

Effect of Low-level Light Therapy on Post-operative Healing of Secondary Chronic Osteomyelitis of the Jaws - A Prospective Study

“…Aside from osteomyelitis research, the effect of LLLT on bone repair was thoroughly carried out and showed stimulation of bone production;[ 30 31 32 ] therefore, the positive effect of this treatment modality can be postulated. A stimulating effect was recorded in terms of blood and lymph neovascularisation,[ 33 34 ] synthesis of RNA, DNA, collagen and its precursors, as well as positive effects on the levels of prostaglandin, phagocyte cytoplasmic granules, cell proliferation and production of adenosine-5’- triphosphate. [ 35 36 ] Furthermore, an existent penetration of LED 635-nm low-level light through the soft and hard tissues of the jaws was demonstrated[ 37 ] which implies that the complete jaw bone thickness receives therapeutic doses.…”

Dosimetria do Laser de Baixa Intensidade para Cicatrização de Úlcera Venosa: Um Protocolo de Revisão Sistemática

“…Its use is safe and valuable in wound treatment due to its wound-healing, anti-inflammatory, analgesic, and edema-reducing effects, reducing the recurrence rate of deep ulcers (5)(6) . In addition, a systematic review of the effects of LLLT on ulcers due to diabetic vasculopathy suggests that adjuvant therapy may improve neovascularization and minimize the risk of complications (7) . Light Amplification by Stimulated Emission of Radiation (LASER) uses electromagnetic radiation, which differs from normal light due to its specific physical properties.…”
