The objective of this randomized controlled clinical trial (RCT) with a double-blind technique and longitudinal chronology, entitled \"Effect of different laser applications on Plantar Fasciitis\", is to evaluate and compare the effectiveness of laser therapy low-level (LLLT) in local spot mode versus sweep mode in the reduction of pain associated with plantar fasciitis. The main questions it seeks to answer are: * What is the comparative effectiveness between low-level laser therapy in local spot mode and sweep mode in reducing pain in patients with plantar fasciitis? * What are the optimal therapeutic parameters (session duration, frequency and power) for LLLT in both modes, maximizing pain reduction in patients with plantar fasciitis? Participants in this study will perform the following tasks: * Undergo low-level laser therapy sessions in local spot mode or sweep mode. * Comply with the instructions on the duration and frequency of the sessions. * Record the pain levels experienced before and after each session. The investigators will compare the group undergoing local spot mode low-level laser therapy with the group undergoing sweeping mode low-level laser therapy to evaluate whether there are significant differences in pain reduction effects.
