“…Apesar de ter utilizado métodos diferentes, Marques et al (2004) também observaram melhora da cicatrização tecidual e redução da ulcera em todos os pacientes. em experimentos com ratos diabéticos, investigaram a eficácia do laser com comprimento de onda semelhante ao da presente pesquisa associado ou não ao fator de crescimento e observaram melhora na cicatrização nos grupos que usaram o laser.…”

ResumoO emprego de fontes de luz de baixa potência, como diodos emissores de luz-LEDs, pode propiciar um recurso terapêutico opcional aos convencionais ou ser utilizado em conjunto com estes, com a vantagem do baixo custo e comprovada eficiência no tratamento de úlceras e outras enfermidades. O estudo de caso foi realizado com um paciente do Ambulatório de Clinicas do HC/UEL que apresenta úlceras nos membros inferiores. A aplicação foi feita uma vez por semana, empregando LEDs com comprimento de onda de 628 nm na úlcera do membro inferior esquerdo e o direito foi utilizado como controle. A evolução foi medida por meio de registro fotográfico, medida da área e mensuração da dor. Foram realizadas 18 sessões. Os resultados apontaram mudanças nas características clínicas da lesão e a área cicatrizada foi 30% maior em relação à úlcera controle. Quanto à dor, a escala análoga visual variou de oito para zero no membro irradiado e de nove para dois no controle. Assim, podese concluir que a LED terapia é um recurso de eleição no tratamento da úlcera venosa, nos aspectos cicatriciais e redução da dor. Palavras-chave: Úlcera. LED. Cicatrização. AbstractThe use of low power light sources, such as diodes emitters of light -LEDs, provides an alternative and complementary therapeutic resource to the conventional ones, with the advantage of being cost-effective and reliable in the treatment of ulcers and other infirmities. This study was carried out on a patient from the HC/UEL Outpatient Clinic with ulcers on both lower limbs. LEDs were applied once a week, using a wave length of 628 nm on the left lower limb ulcer ,using the right limb as control.

“…Testes clínicos com aplicação de LEDs em cicatrização de úlceras em seres humanos já foram liberados pela FDA (Food Drug Administration) norte-americana (WHELAN et al, 2001). Trabalhos recentes desenvolvidos no Brasil demonstram a eficiência deste recurso para o tratamento de diversos tipos de úlceras (CORAZZA, 2005;MARQUES, 2004).…”

“…In fact, the novel devices emit light with wavelength of 627 and 945 nm, respectively, presenting optical power of 70 and 135 mW. These values are suitable to application in photobiostimulation, which can be inferred in previous works that presented the employment of these devices emitting in the red region (approximately 630 nm) [1,15,16].…”

A novel opto-mechanical system constituted by LEDs to employment in photobiostimulation: Clinical application in optical therapy

et al. 2012

Optical techniques of photobiostimulation, which use transducer as lasers and LEDs, have been employed in the treatment of several diseases. The laser systems usually irradiate in a reduced area of the target biological tissue, presenting high cost of acquisition. Devices with a LED of Surface Mount Device (SMD) type have high angle of light emission, implying in intense decrease of the density of optical potency. Furthermore, the use of this device requires the utilization of a cooling system, which provokes an increase in the cost of this product. In the present work, it is suggested the application of a novel opto-mechanical device constituted by usual LEDs with package dimension of 5 mm of diameter, which presents significant efficient and very low cost. The arrangement of the geometric configuration of these LEDs is elaborated in such way that all units emit photons in a unique section of an specific area. An opto-mechanical system was developed, which includes seven LEDs, being that six of these LEDs are disposed in a specific angle around a unique central LED. It is important to notice that all the opto-mechanical system with seven LEDs emit light in a unique area. Besides, a methodology was employed to allow the verification of the distribution of light intensity upon this respective area. This arrangement allows that this novel device propitiate measurements of the degree of homogeneity of the light intensity in specific areas, which are accessed by the seven light emitting units. The potency employing LEDs in the red (visible) and near infrared regions were also measured, being that the result demonstrated the capability of clinical application in optical therapy of photobiostimulation, which was also used in a pilot test of clinical application.

“…For example, the red light, near the infrared, easily penetrates the fabric because they are not blocked by blood and water as other wavelengths do. Wavelengths of less than 630nm such as yellow, blue and green are considerably blocked by the hemoglobin in the blood, so they do not penetrate deeply (Marques C. et al, 2004). You can check this, for example, as a bright light through your fingers (the wavelength in red can cross).…”
