TRANSCUTANEOUS LASER IRRADIATION OF BLOOD IN SIMULTANEOUS MODE (S-ILIB) FOR FATIGUE RECOVERY

The modified transcutaneous laser irradiation on blood (ILIB), a systemic modality of photobiomodulation therapy (PBMT), consists of a laser application on the radial artery or other artery in the body, to improve systemic functions and physiological dynamics of the body. The available therapeutic strategies for the management of fatigue due to daily life stress are mainly focused on lifestyle changes associated with nutrition and exercise. Thus, the present study aims to report a series of cases in which transcutaneous modified ILIB therapy in simultaneous mode (S-ILIB), was used to treat fatigue symptoms. Four healthy patients, without any type of significant comorbidity, reported fatigue related to stress. They were treated by the new PBMT protocol with the modified ILIB technique. The intensity or perception of fatigue was rated using a visual analogue scale (VAS). The "simultaneous technique" used in the present study consisted of laser irradiation in four sites of the body: 1- the radial artery region of the right arm; 2- the radial artery region of the left arm; 3- the right dorsal pedis artery; and 4- the left dorsal pedis artery. For PBMT, two laser device were used at 660 nm, on contact mode, with 100 mW of power. The patients reported a clear recovery in the energy sensation after the S-ILIB session. The PBMT protocol seems to be a promising therapy for managing energy recovery in fatigue-stress-related daily routines; however, complementary studies are required to establish the safest and most efficient protocol
