The objective of this randomized controlled clinical trial (RCT) with a double-blind technique and longitudinal chronology, is to evaluate and compare the effectiveness of High intensity laser therapy (HILT) in static mode versus scanning 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 HILT sessions or scanning 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 this differents laser to evaluate whether there are significant differences in pain reduction effects.

This randomized controlled clinical trial, titled 'Effect of Different Laser Applications on Plantar Fasciitis', aims to specifically address the effectiveness of static mode versus scanning mode (HILT) in the treatment of pain associated with plantar fasciitis. Using a rigorous methodology that includes double-blind masking and a longitudinal chronology, the study focuses on comparing two modes of laser application.

The main objective is to evaluate and compare the pain reduction between these two modes of application of LLLT. To achieve this, key questions are asked, such as the relative effectiveness of each mode and the identification of optimal therapeutic parameters, including session duration, frequency and power, that maximize benefits in patients with plantar fasciitis.

Participants in this study will undergo low-level laser therapy sessions, following the protocols established for each mode of application. Additionally, they will be asked to record their pain levels before and after each session, providing valuable information about the effectiveness of the therapy.

In the case of a comparison group, a detailed evaluation will be carried out comparing the results obtained between the group treated with static in local spot mode and the group treated in scanning mode. This approach will allow researchers to determine if there are significant differences in the pain reduction effects between the two modes of laser application.

With a solid experimental design and specific objectives, this study seeks to contribute significantly to the understanding of laser applications in the treatment of plantar fasciitis, providing valuable information for the optimization of therapy and thus improving the quality of life of patients. . affected.
