Light-emitting-diode in Diabetic Subjects

Summary

Diabetes mellitus (DM) is a metabolic disorder, characterized by hyperglycemia and metabolic disorders, resulting in changes in insulin secretion and / or action. Physical function is critical for functional independence, and chronic diseases such as diabetes can lead to functional decline, and diabetes mellitus is a major contributor to the progression of sarcopenia and physical disability. DM is also known to have a strong associated with the development of peripheral arterial disease. Peripheral arterial disease is characterized by obstruction of the arteries of the lower limbs, leading to a low oxygenation of the muscles of the lower extremities. Among the physiotherapeutic resources that can be used, phototherapy involves the use of light for the treatment of muscular injuries, by modulating the physiological processes associated with the repair process. Clinical trials show that light emitting diode (LED) is a technique that interferes with muscle strength, generating an increase in maximal voluntary contraction and peak torque. It is hypothesized that the LED application is capable of improving the muscular strength, fatigue, functional performance and blood flow capabilities in individuals with diabetes. It is also expected that the results of this study may contribute to and increase the resources used by physiotherapists within the clinical scope, contributing to the care of diabetic patients.

Conditions

• Diabetic Neuropathies

Interventions

DEVICE

Red Light-emitting diode device

The phototherapy will be applied for 3 days followed by a red LED blanket of 25x40 cm2, with equidistant distribution - 1 cm between them, with total energy per area of 180 J, bilaterally on the anterior tibial and triceps sural muscles, bilaterally. The intervention of these muscular groups is made possible by the distal involvement of diabetic polyneuropathy. All LEDs will be checked at the beginning of the project in the Laboratory of Photophysics of the Faculty of Philosophy, Sciences and Letters of Ribeirão Preto, University of São Paulo, in which the wavelengths will be checked, the angle of radiation, power and power density.

DEVICE

Infrared Light-emitting diode device

The phototherapy will be applied for 3 days followed by a infrared LED blanket of 25x40 cm2, with equidistant distribution - 1 cm between them, with total energy per area of 180 J, bilaterally on the anterior tibial and triceps sural muscles, bilaterally. The intervention of these muscular groups is made possible by the distal involvement of diabetic polyneuropathy. All LEDs will be checked at the beginning of the project in the Laboratory of Photophysics of the Faculty of Philosophy, Sciences and Letters of Ribeirão Preto, University of São Paulo, in which the wavelengths will be checked, the angle of radiation, power and power density.
