Bonus Discussion: Neutral Spine vs Spinal Flexion | Connecting Biomechanics to Pain Science
This discussion covers:
- Where the idea that neutral spine is a safer position than spinal flexion came from and what past and current research suggests about this topic.
- The benefits of being able to generate spinal stiffness and access spinal mobility based on the activity that you are practicing.
- A brief overview of pain science and how to teach from a place that utilizes both pain science and biomechanics approaches
- General guidelines for choosing when to use a neutral spine or focus on spinal movement (e.g. spinal flexion, side bending, rotation, or extension)
- How the client’s experience, activities, and goals will influence exercise selection and when or how to introduce flexion based movements
