The Origin of Structural Integration
You may have heard of Rolfing, named after Dr. Ida Rolf, the founder of structural integration. You may also have heard of the Anatomy Trains Structural Integration series, or ATSI, another school that evolved the SI approach under Thomas Meyers, student of Ida Rolf and founder of ATSI.
Understanding the difference between these two schools clarifies why the Anatomy Trains Structural Integration approach is desgined for you.
Xavier and Natalie, both Board Certified Structural Integration Practitioners at Somatic Healing and Alignment, offer the Anatomy Trains 12 series to clients throughout Lakeville, Edina, and the greater Twin Cities area.
There are Two Common Misconceptions About Structural Integration
Why the Structural Integration Series Provides Lasting Change
Rolfing vs. Anatomy Trains: Two Schools, One Foundation
The second misconception stems largely from a lack of public awareness about structural integration as a broader field of bodywork.
The lack of awareness is largerly becasue structural integration is ahead of its time in terms of full body pattern recognition and therapeutic application. Connecting the dots of pain in one area being driven by a distant relationship elsehwere.
The rest of the western world of bodywork and health has been too focused on old models that rely on how the scapel cut through the body and the deductions made from it instead of looking at how people develop from embryo (and altering scapel angles). These deductions and conclusions can not even explain the complex interplays of walking.
Everyone else not elightened to the approach of structural integration are finally coming around thanks to the efforts of many people within different fields connecting the dots of fascial function.
For clarity, the rest of this blog compares the Rolfing approach and the Anatomy Trains Structural Integration approach to the series, highlighting where they diverge and why those differences matter.
The Rolfing 10 Series vs. the Anatomy Trains 12 Series
The first major difference between Rolfing and the Anatomy Trains series is length.
Rolfing offers a 10 session series, whereas ATSI offers a 12 session series. A 3 series option also exists, though that falls outside the scope of this blog.
Why does the Anatomy Trains Series Added Two Sessions to the Rolfing Recipe?
- The superficial sleeve rotation, the outer layer of myofascia
- And the myofascia along the arms into the shoulder girdle
How the Session Territory Compares Across Both Series
In general, the Rolfing and ATSI sessions cover similar territory within their respective series. However, two sessions present in the ATSI 12 series do not appear in the Rolfing 10 series:
| ATSI 12 Series | Rolfing 10 Series |
|---|---|
| Superficial Front Line | Session 1 |
| Superficial Back Line | Session 2 |
| Lateral Line | Session 3 |
| Spiral Line | Not Present |
| Deep Front Line Lower | Session 4 |
| Deep Front Line Torso | Session 5 |
| Deep Back Line | Session 6 |
| Deep Front Line Head | Session 7 |
| Pelvic Girdle Down | Session 8 |
| Pelvic Girdle Up to Shoulder | Session 9 |
| Arm Lines | Not Present |
| Balance Whole Body Spine Out | Session 10 |
For more detail about each line there is an overview of the series, for the dedicated reader, there is a book written by Thomas Meyers, and for everyone, book the first session of the 12 series to develop an intimate personal relationship with these lines across the sessions.
Why the Sprial Line Session Matters in the Anatomy Trains Series
The fourth session, spiral line session, of the ATSI 12 series addresses the superficial sleeve rotation before delving into the deeper myofascial core rotation. The Rolfing 10 series skips this step entirely.
Without first unraveling the superficial sleeve rotation, resolving the deeper core rotation becomes significantly more difficult.
Becasue the superficial sleeve, the myofascia you see, the abs, the thigh, and chest, directly counters the deeper core. If you have ever tried to unwind a cord without knowing where the end is, it would be a similar feeling if you did not address the counter rotation. Therefore, the addition of the spiral line session in the ATSI series creates more opportunity for meaningful change.
Why the Arm Line Session Strengthens the Anatomy Trains Approach
The other session absent from the Rolfing 10 series is the 11th session of the ATSI 12 series. This session addresses the myofascial roots of the arms, think in the armpit, and works all the way down to the hands.
While both the Rolfing and ATSI series touch on the roots of the arms throughout the series, Rolfing does not allocate a dedicated session to the full arm the way ATSI does.
The purpose of this session is to drape the shoulder girdle and arms over the newly supported core, the deep front line. Because patterns held within the arms affect the axial body and vice versa, addressing the full arm provides substantially more space for whole body change.
Why Choose the Anatomy Trains 12 Series
The 12 series is designed specifically to catalyze change throughout your entire system. That means unraveling the maladaptive patterns and deviations from neutral that have been set into your body since you first learned to move as a child.
This idea is not entirely new. Movement modalities developed long ago, such as the asanas within Yoga, offer a similar path.
However, what sets structural integration apart is the speed at which change occurs, the relatively small investment of time required, the series’s ability to activate the body’s own natural drive toward health, and the bodywide pattern based approach. In terms of physical alignment, that means guiding the body to move within gravity toward neutral, while also honoring the emotional and mental change that naturally follows.
