spinal curves

This blog post is about sitting with a backrest, which could be the back part of a chair, or something added to the chair for additional support and comfort. 

A well-designed backrest can contribute to a healthier back—but a poorly designed one can cause tension and pain. Pexels

Support and relief

Virtually any backrest will give relief that a tired back will appreciate. Support is certainly preferable when we sit for longer periods of time to enjoy reading, TV, a movie, or, if we are lucky, live theater. 

With the trunk slightly inclined against a backrest, there is less compressive force due to gravity acting on the spine. In addition, the trunk stabilizer muscles get a break. When we are driving or traveling by plane or train, a backrest also confers additional protection from vibration or any untoward impact. 

Backrests can certainly improve your comfort but it is also true that many do more harm than good. It makes sense to be discerning about your backrests and to understand the ways in which they can help or hurt.

Shaping your back 

There is unfortunately a significant disadvantage that is built into most modern backrests. A backrest will shape your back as you lean into it and almost all backrests introduce excess curvature, with a significant concave curve in the lower back (lumbar area) and a significant convex curve in the upper back (thoracic area). This is driven by the incorrect paradigm of the S-shaped spine.

This spinal shape is considered to be normal (as well as ideal) in today’s conventional wisdom. Physical therapists and medics are taught this S-shape paradigm, which is explained in detail in my book, 8 Steps to a Pain-Free Back, and in our blog post Which Shape is Your Spine? 

The S-shaped spine has become the concept that determines the design of our furniture, including backrests for chairs and car seats. 

Most backrests follow the S-shaped spine paradigm and are designed to give “lumbar support.” This creates exaggerated curvature and compression in the lumbar spine.

Office and gaming chair backrests are often engineered with exaggerated contours. These distort the spine’s natural alignment. Such excessive curves curtail the spine’s ability to lengthen.

This style of easy chair has less drastic curves but will still result in some lumbar and upper back distortion; it also pushes the shoulders and head forward. Back2.co

This lounger has a mild thoracic curve which still encourages the upper back to round. 

What you want is a backrest that reflects and promotes the healthy spinal shape that we all enjoyed as toddlers and is still prevalent in many nonindustrialized areas of the world. The shape of a modern letter “J” is a good shorthand to describe this relatively straight alignment of the vertebral column and the pronounced angle at the lumbosacral junction. Unlike the S-shaped spine, there is no exaggerated lumbar sway or thoracic curvature. You can see this shape embodied in the Ubong hunter’s torso shown below. It is J-shaped rather than S-shaped. 

These Ubong tribesmen have a J-spine.

This medical illustration from 1911 more closely depicts the J-shape spine rather than the S-shape of modern conventional wisdom. The only pronounced curve is at the L5/S1 junction at the base of the spinal column.

A backrest with gentle traction

Beyond supporting a healthy J-shape in your spine, ideally a backrest would also stretch your spine, especially in the lumbar area. With a little know-how you can get hours of therapeutic traction into your day, reducing pressure on your spinal discs and nerves and improving circulation in the surrounding tissues. We call this combination of healthy shape and traction stretchsitting.

This schoolboy in Brazil has healthy posture and instinctively uses the backrest to stretchsit, lengthening his spine. 

How to choose a backrest

1. If your chair’s backrest already offers some friction (e.g., textured fabric) and you don’t mind adjusting it when you sit, a folded towel can serve you adequately for stretchsitting. This video will show you how.
2. Our Stretchsit® Cushion creates healthier contours and provides traction with its soft, grippy nubs. It comes with extension straps that hold its position without repeated adjustments.

The Gokhale Method Stretchsit® Cushion comes with adjustable straps and can transform most chairs and car seats.

3. The Gokhale Pain-Free™chair is designed to provide healthy contours and traction for stretchsitting. It has the additional advantage of having a built-in wedge, a waterfall front, and other features making it suitable for stacksitting (sitting without a backrest). 

The Gokhale Pain-Free™chair has a custom forged “back upright” (the metal piece that goes between the seat pan and the backrest) to allow your behind to be behind. This allows your spine to have a healthy J-shape. The backrest has sticky nubs sewn into it to provide therapeutic gentle traction.

At the beginning of the pandemic, my tween daughter was the dancer in my house. When her in-person hip-hop class was canceled, she quickly turned online for inspiration, showering me with her 30-second Tik Toks.

I was amused, but resolute that dancing online was not for me. I had my own exercise regime, at the heart of which were a series of Pilates-based exercises that I had incorporated in the hopes of healing a nagging injury. 

But now, 16 months into the pandemic, I’m dancing online too, maybe even more than my 12-year-old. This is thanks to Esther Gokhale and her unbelievably fabulous community who, like me, wanted to find a safe, therapeutic, and fun way of exercising after injuring our backs.

I first heard Esther years ago on a podcast and subsequently checked her book 8 Steps to a Pain-Free Back out of the library. I remember being especially interested in the pictures of women holding their babies so comfortably; I had recently given birth, and I tried my best to imitate the women pictured. 

Me with Baby Yael in 2013. I now see I had a very pronounced S-shape curve. 

From reviewing pictures of myself during that time, I see now that I did a poor imitation, but at the time I didn’t have any pain, so I returned the book to the library. 

However, last November while experiencing non-stop back pain, I purchased the book, which led me to Esther’s website and one-on-one coaching. Six weeks later, after completing the Elements course, this is what I wrote to friends and family in my 2021 New Year’s letter:

I’ve been relearning how to walk, stand, and sleep over the past six weeks. This is what one does when she becomes so desperate for relief from unrelenting sciatica, the kind that starts in the buttock and runs down to the calf. It all began with a yoga injury in May 2019, but the pain became unbearable after our move (hello, stress and grief, and, yes, more disc degeneration.)

An MRI from December 2020 had pinpointed “severe facet arthritis bilaterally” at L4-5, and mild to moderate facet damage elsewhere. I had tried everything from PT to Pilates, from massage to medical marijuana, but what seems to have made the biggest difference is the Gokhale Method, which attempts to reteach the body how to do the work of everyday life without further degrading our discs.

I was skeptical about how much I could actually learn online from a Gokhale coach, given that postural work benefits from hands-on adjustments and corrections. But with COVID-19 raging, this is not the time for in-person classes. Happily for me, my coach was terrific, and after completing the 18 introductory classes, I’m feeling so much better. It’s definitely not a magic bullet, but it’s the best thing I’ve tried so far, and I want to believe that if I keep it up, I’ll eventually be pain free. Here’s hoping I can report that next year.

Seven months later, I am thrilled to say that I am indeed pain-free and living a full life that enables me to care for my family, return to writing, and relaunch my health coaching practice that I had put on hold due to the pandemic and pain.

My recovery has been so complete that in May I undertook training to become a certified canoe instructor and am now teaching at the American Canoe Association’s Camp Sebago in New York. 

Now free from back pain and sciatica I am once again able to canoe.

Even though I feel great, I know that wellness takes regular work, and I’m grateful for the ongoing Gokhale Exercise program. Gokhale Fitness teacher Eric Fernandez has gotten me to enjoy strength training; teachers Kathleen O’Donohue and Roberta Cooks are responsible for me incorporating Moving Meditation into my morning routine, while Esther’s daily 1-2-3 Move program has rekindled my love of dance and taught me steps from traditions that include bharata natyam, samba, capoeira, 50s rock, and reggae. Joan Baez’s music is a fave—she is a student of Esther’s and will often be dancing on the screen with the rest of us. 

Head-loading is a fun way to practice many important posture principles, shown here on the 1-2-3 Move program. 

Esther will also occasionally focus on yoga asanas and offer modifications that have enabled me to safely return to a yoga practice. If you see me balancing boxes (or my canoe) on my head, it’s thanks to all the practice I’ve now had with the Gokhale™ Head Cushion, gently “head-loading” my way to a taller, healthier neck. Thanks to the Gokhale Pain-Free™ Chair and Gokhale Stretchsit® Cushion, I’m also able to sit well at my desk and to drive long distances without pain, something that was impossible seven months ago.

1-2-3 Move often features artefacts such as Greek statues, Indian deities, or photographs of people from different cultures going about their work. Esther points out that examples of healthy posture by Americans are more readily found some generations back, in works such as those by Grant Wood or Winslow Homer.

My favorite class was the one devoted to the Hindu deity Ganesh, who takes the form of an elephant with a pot belly. While dancing to the “Ballad of Ganesha” by Lil Darkie, we took a cue from Ganesh, who holds himself beautifully, despite his roly-poly largesse. Esther talked about how strong abs are something that everyone, no matter what size, can cultivate. If Ganesh can carry himself well, the rest of us can do so as well. She made a similar point using images of Japanese sumo wrestlers. I deeply appreciate that Esther, raised in India by her Dutch mother and Indian father, takes a global perspective on healing.

As a Functional Nutrition and Lifestyle Practitioner, I’ve come to view the Gokhale Method as nonnegotiable, or what Andrea Nakayama, CEO of the Functional Nutrition Alliance, calls “Tier 1”—the basics that must be in place before supplementation (Tier 2) or any kind of medical intervention (Tier 3). 

Tier 1 includes community support, something that is available in any Gokhale Method group class. These social and emotional components of healing, and the importance of surrounding yourself with healthy posture cues from people, artwork, and music, are frequently discussed during the Q&A on the 1-2-3 Move program. 

In this 1-2-3 Move video, Esther shows how traditional artefacts such as shadow puppets from Java, Indonesia, inspire us to free our arms and open the chest.

The Gokhale Method is not against appropriate medication or procedures. Back in February when I was still having some pain upon waking every morning, I asked Esther what she thought of “injections” as a way to mitigate this. To my surprise she said that she sometimes suggests that her students consider this “Tier 3” approach, but only after they have tried “Tier 1” first. Medical interventions such as injections and painkillers can create a window of pain-relief that enables students to learn to improve their posture and address the root cause of their problem. 

I had already had an injection into my SI joint the previous September, which didn’t give me any relief. So I booked a one-on-one appointment with Esther, who pinpointed an excessive curve in my lumbar area. The transformation I brought about in my spine led to me being used as an example of progress in a blog post about spine shape. 

My “before” (above) and “after” (below) Elements photos show a considerable change from an S-spine towards a J-spine. You can read more about spine shape here.

With ongoing attention to creating more of a J-spine and less of an S-spine I no longer have pain. Perhaps even more importantly, I have greater trust that my body, with the right support, can heal.
