In order to receive full CBP® accreditation for this course please complete the quiz at the end of the course. When you finish the last lesson the quiz will be available. Thank you!

This course provides an integrated education for the Doctor of Chiropractic in the science and art of spine, posture, and lower extremity disorders. The total permutations of abnormal posture using formulas from probability theory will be delineated and a literature review on postural displacements as they correlate to patient conditions will be provided. The details of objective postural assessment and measurement will be reviewed. The Chiropractor will learn corrective global postural subluxation set-ups for the head, thoracic cage, & pelvis on a drop table. To provide diagnosis, analysis and course of care for short leg syndrome and lower extremity disorders. A survey of research material will be reviewed supporting the utilization and efficacy of Chiropractic Biophysics drop table technique treatment methods across a population of patients with chronic pain conditions.


You can start and stop the course at any time. The course is available in your account for 6 months
A test is provided at the end of the course with 31 questions, 75% score required. You have 5 attempts and 2 hours to complete the test.
