Scientific Studies

The clinic follows Evidence Based Chiropractic. This means that the approaches and techniques that are performed on you will have proven scientific studies demonstrating the success. The following are a few of the clinical trials and published studies that show the success of the techniques we use at JL Quiropráctico.

Activator Chiropractic

The Activator Method has more than a 100 published research papers. The following are a few of the more relevant and significant studies.
