Introduction: Tendinopathy is characterized by localized pain in the tendon and is related to physical activity, edema, increased sensitivity in the tendon region, decreased strength and range of motion, characterizing decreased function. Although advances have been made in relation to scientific evidence in the treatment of tendinopathies, photobiomodulation (PBM) still presents divergences in dosimetry and application techniques regarding clinical efficacy. Thus, it is necessary to conduct clinical studies that investigate the effect of photobiomodulation in relation to dosimetry on tendinopathies. Objective: To compare the effect of FBM with single or cluster when associated with eccentric exercise on pain intensity and function in patients with lower limb tendinopathy. Method: Randomized, uncontrolled, blinded clinical trial. It was developed at the Federal University of São Paulo - UNIFESP, Baixada Santista campus. The volunteers were randomly distributed through the website “randomization.com”. 42 volunteers were randomly assigned to two groups, 21 of which Group 1: PBM cluster associated with eccentric exercise and 21 in Group 2: single PBM associated with eccentric exercise. The exercise protocol was performed twice a week for 4 weeks. The application of PBM was performed after the protocol with the following parameters: FBM single 810 nm (GaAsAl) for 6 J (30s per point - 3 points), and 200 mW of power and FBM cluster 5 x 810 nm (GaAsAl) 200 mW , 6 J (30s per point totaling 30J per cluster area and 1W of power). The evaluations were carried out in 3 moments: pre-treatment, end of treatment (4th week) and follow-up of 4 weeks (8th week). Were used: NRS-11, VISA-P or VISA-A, DN-4, IPAQ, Pressure pain threshold (PPT), modified blazing scale, lunge test and LEFS. An independent sample t test was performed for the analysis of the primary outcome (VISA at the 4th week) and for other analyzes, repeated measures ANOVA and the effect size calculation were used. Results: The VISA questionnaire at the 4th week showed no difference between the groups (p = 0.81, s = 0.06). For other analyzes, there was no intergroup difference. For the activity that causes the most pain measured by the NRS-11, there was no intergroup difference (p = 0.79 and es = 0.08). Regarding the LDP, there was no intergroup difference (p = 0.3 and es = 0.37). Conclusion: There was no difference between the modes of application of FBM (cluster and single) in the symptoms, measured by the VISA questionnaire, in patients with patellar and Achilles tendinopathy.
