ELDOA Level 4 is four days in length. The priority of this module is all things sacra-iliac joint and pubis symphysis including an in-depth study of the biomechanics of the pelvis and one day review of all the ELDOA exercises taught in the program up to this point, done in an interactive format, allowing for feedback and class discussion. Instructor prompted clinical scenarios will be used to enhance the course work with respect to the exercise application. Group exercise will be taught each day by a student in this course.
