Course Description This 2-hour online course will provide students with foundational knowledge on lower extremity biomechanics and orthotic theory. The fundamental of key orthotic theories such as Root, SALRE, Tissue Stress will be reviewed as well as the biomechanical consideration that lead the student to the best orthotic selection for the patient’s specific condition. This course is the primer to Vasyli Medical Biomechanics Academy library of additional courses which drill down further into orthotic application in specific instances. Learning Objectives By the end of this course, the participant will be able to: 1. Establish relationship of nature vs common era functional surfaces and its effects on foot biomechanics 2. Successfully identify a minimum of 5 foot/ankle anatomy landmarks 3. Understand the key biomechanical theories and their interrelation 4. Successfully comprehend the 4 axis of motion and their relation to foot and ankle mechanics 5. Identify the key factor to success orthotic prescription.
