Applied Kinesiology uses manual muscle testing to evaluate the central nervous system's response to various stimuli. This document summarizes Applied Kinesiology techniques for assessing adrenal gland function, including associated muscle weaknesses, symptoms of adrenal stress, nutritional support, and case studies demonstrating AK's principles. While some research supports AK's reliability, other studies found manual muscle testing results were not better than chance or consistent with predefined nutrient assessments.
