Most asked questions scoliosis clients ask me about exercise:
- Should I perform some exercises just on one side?
- Should I choose exercises that rotate me to the opposite direction of the curve?
- Should I do an extra set of movements to one side?
- I just saw research that side plank exercises can reduce curve degrees…should I be doing these?
What is the Pathomechanism of Idiopathic Scoliosis? (the short version!)I will be brief since this is a whole course in itself! We know that Idiopathic (no known cause) Scoliosis (IS) is a 3 dimensional spinal disorder that begins with anterior vertebral wedging due to RASO (relative anterior spinal overgrowth) during bone development. We also know that the rotational component of scoliosis exists as both inter-vertebral torsion (rotation of one vertebra relative to another) and intravertebral torsion (an internal rotational distortion within each vertebra), most notably at the apical vertebra (the vertebra most deviated laterally from the vertical axis that passes through the sacrum).1 This distortion contributes to less joint motion at the apex of the curve and more at the transition points of the curve. We see this to a greater degree in adults and to a lesser degree in adolescents who have a more flexible curve before bone maturity. This is apparent in a supine lateral flexion X-ray that assesses curve flexibility.
Three Goals for our Clients with ScoliosisMovement educators can keep 3 goals in mind when choosing exercises for clients with IS:
- Achieve better postural alignment along the central axis
- Provide a safe fitness option to increase flexibility, strength and fluid movement
- Support sports, recreation and functional activities that enhance quality of life
We Can Improve Posture Through Exercise!Better posture can be achieved by emphasizing the most fundamental principles of all intelligent movement disciplines: axial elongation and breathing. Scoliosis curve concavities are constantly under compression by gravity. Axial elongation encourages a natural re-alignment of the spine by using neuromuscular activity to reduce multi-plane compression and collapse of the concave side of the scoliosis curves. Once the concavities (which include the ribs) are expanded, then breath can be used to further open the collapse through:
- Tactile cueing of the concavities
- Unilateral nostril breathing
- Guided imagery
The Side Plank Research ControversyA research article was published in 2014 claiming that scoliosis curves can be reduced by doing side planks on the convex side of the curve, and was sensationalized in a WSJ article.2 But the research had many flaws3 and while interesting, it cannot make that claim. Muscular activity on both the concave and convex side of a scoliosis curve is inefficient and exercises that address each side are optimal for IS, including the Side Plank. Consider benefits of the Side Plank based on curve type:
- Single Major Thoracic Curve: performing side plank on the convex thoracic side (concavity up) can help strengthen elongated muscles on this side by placing them in a relatively shortened position, and helps to open the concave side, working these muscles eccentrically.
- Double Curve, Primary Thoracic: the same can be true for the thoracic curve but now the lumbar curve may be more compressed and specific cueing and/or modification of the exercise must be considered.
- Double Curve, Primary Lumbar: performing side plank on the convex lumbar side may be beneficial, but the thoracic curve may be more compressed, and will require special cueing or modification.
- Single Curve – Lumbar or Thoraco-lumbar: performing side plank on the lumbar or thoraco-lumbar convex side may strengthen elongated muscles on this side by placing them in a relatively shortened position and helps to open the concave side, working these muscles eccentrically.
- Adult with Degenerative Scoliosis (Lumbar): receive the same benefits as Single Lumbar curve but if there is a lateral instability (listhesis), then this exercise may not be indicated.
Safe Exercises for Spine MobilityLife takes us out of neutral spine…shouldn’t we train our scoliosis clients how to move their spine effectively out of neutral? The answer is of course yes…. but which movements and how much? This depends on your assessment of the client: Are they in pain? How much movement does the apex of each curve have? What is the curve type? What other muscle imbalances or injuries exist? What are their goals? Considering that the scoliosis spine tends to move more at the transition points and less at the apices, we may want to limit end range movements and emphasize elongation in postural shapes that minimize compression of the curve concavities. This will be more difficult for those with a double curve. So it is important to make critical decisions with your client based on your evaluation and their goals.
Recreation and Sports: Can it Be Done with Scoliosis?Everyone with scoliosis should be free to enjoy activities that increase quality of life! What does you client love to do? Sports activities such as dance and gymnastics involve many compressive spine positions for scoliosis….as do golf and tennis. Each person must be evaluated for the risk that their chosen activity may have on their scoliosis. Considerations for age, curve type, activity frequency, and muscle imbalances must be made. Clients should be educated about scoliosis spine mechanics and progressions to help them make an informed decision about the activity they choose. A fitness or movement session with your client could focus on training to maintain axial elongation and openness of the concavities during sport. Just as likely and equally important, a session could simply focus your client back to their center line!
Education and the Need for Individualized ProgramsPolestar founder Brent Anderson, PT, PhD, OCS reminds us of the importance of working within our own scope of practice. It is crucial to invest in your education to increase your effectiveness and level of safety with your scoliosis clients. Find a professional you can partner with, join a network of practitioners with like interests, and take courses to keep yourself current with scoliosis research. If you are the client, make sure that your Pilates teacher or therapist has the training to create safe and effective exercise programs for you and your needs.
