Clinical Reports describe the use of EFT with various groups, e.g., university students, prisoners, refugees, or abused children. They may contain quantitative data such as scores on symptom assessments or they may describe the ways in which practitioners can work with this population.
The "mechanisms of action" for a technique such as EFT describe what is happening in the body during application of the technique. These papers describe the neurological, epigenetic, psychoneuroimmunological, and hormonal pathways engaged by EFT.
