Dr. Bridwell is a talented healer. She explains everything she is doing and has helped me with chronic pain from my job. She is also an avid listener and caters her treatments to what you want. She also calls you 'baby' when she cracks you, which really ads that something special. I would recommend her to anyone, especially those who have a hard time being touched.

I went to school with Dr. Stephanie, have studied along side her for several years and now have the amazing opportunity of working with her at Magnolia Chiropractic.
Just when I think Dr. Stephanie is the most compassionate, committed, kind and thoughtful Doctor I have ever met, she raises the bar again. Anyone who has the opportunity to seek care with this incredible person will not be disappointed. Her dedication to the work and to providing excellent, professional and personal care to any individual who sets foot in her office is unparalleled.
Dr. Stephanie inspires me E V E R Y day to be a better doctor and a better human being.



I went to Magnolia Chiropractic Center in San Francisco three weeks ago due to a burning sensation in my low back which ran down my leg. I was afraid of going to a Chiropractor, but Dr. Stephanie was incredibly gentle, knowledgeable, and really understood the pain I was having in a way that took away my fear and helped me to feel more at peace. I highly recommend getting care from Dr. Stephanie Bridwell, she is a true healer. Learn more about the center. The website is www.MagnoliaChiropracticCenter.com

After a recent cross-country move, I was experiencing many survival pattern discomforts [neck, hip and low back pain], but I was lucky enough to find Dr. Stephanie.

Her skillful, holistic, co-creative approach and nurturing "table-side manner" have helped me breathe through and clear most of these.

In the healing, safe space she holds, each visit reinforces the feeling of well being, flow, trust and integration I want to have all the time.

Each deeper, easier breath brings that vision closer to manifestation.

I've been going to a chiropractor for years getting adjustments when I needed them. They always helped and I felt great until I threw my neck or back out again. Then I met Dr. Stephanie who had a completely new method that was gentle and long-lasting.

She really paid attention to me and I felt very connected to her immediately. She's got amazing intuition and is extremely dedicated to her practice and to making you better.

I owe many thanks to Stephanie and always look forward to walking through her doors.

Dr. Stephanie is the perfect healer!

With her innate sense of humanity, her sincere dedication to Chiropractic, and her love and expression of the adjustment, all new and existing patients will experience a painless, wonderful transformation in their lives.
Stephanie, you are a miracle! You have changed my life with each adjustment. I love coming to your healing center. As my body has been opening up I am becoming more and more aware of what has been binding me. It truly takes my breath away in awe.

Thank-you so very much for all you do.

It was so refreshing to come across a Chiropractor who not only listens to you, but intuitively knows how to access your nervous system into a peaceful state. Dr. Stephanie may seem very youthful, but her deep wisdom of mind-body connection was so powerful. Not only is she great with the gentle stuff, NSA care, but can help you unwind whatever tension may be going on from old injuries ....(may they be mental or physical) Thank you Dr. Stephanie for helping me re-connect to my wholeness and learn more about wellness.

Dr. Stephanie is one of the most talented and loving health care providers in all of the bay area! Her touch is gentle, her presence is always caring, and the effects of her work run very deep. Every time I get off her table, I feel so relaxed and connected to my body. She has helped me break through old energetic patterns that have hindered my own personal growth. Every time I leave her office, I'm sure I've been touched by an angel! She is absolutely the best!



5 of 5 stars. Stephanie is a gifted healer and natural empath. Certainly, yes, she does chiropractic, however, being in her presence you will sense what it is like to be in the company of a real city shaman.

OK, so I normally only promote music / film / art industries, but Dr. Stephanie is fantastic. I broke five of my toes and had six pins holding it together a year ago. I had ligament, nervous and circulatory damage. I had the foot raised for three months and was unable to walk. I have been getting a lot of therapy and Dr. Stephanie has been helping me in the final stages as I have come to get general work done as well. My foot now has the last 5% pronation and I am able to wiggle my toes independently. I highly highly highly recommend that if you see her even if you have reservations. She is gentle and explains what she is doing. I am thoroughly impressed since I typically believe in alternative medical maintenance to keep my body running optimally. If anyone has any questions, I would even be glad to talk to you and I am not the kind of person who does that in general so you should really consider Magnolia Chiropractic if you are having symptoms that you cannot explain. If your nerves are pinched, its like having an aquarium where the air tube is pinched. The fish inside will lack for oxygen because the lid is closing the tubeand the air is not flowing. Well, if that is your blood or nerves, then guess what? Yeah!!! That's right! You'll not be able to think or you'll feel tired or you'll just not feel like 100%. I feel like 173% and I've got a recovering foot. Anyhow, I don't want to make this lengthy, I just want you to get my point. Ask me or ask Dr. Stephanie... BE WELL!

HealingFest Weekend!!!

Magnoia Chiropractic Wellness Center is gearing up for the next Transformational Gate™ Program!!!

The dates have just been announced... August 29-September 2 / Denver, CO
HealingFest 2008 - Back to back programs - The 125th Transformational Gate followed by a Reorganizational Living Seminar.

"We would love to support you in your healing and your desire to attend this program. We will be there to support you in preparation for the program and will be there healing with you throughout the weekend! This program will surely take your care to the next level!!
If this is the first time you have heard about the transformational gate program, the details are below. Please let us know if you are interested and we will get you the information you need to make a decision in regard to your participation. If you are attending and would like your loved ones to come-please get them under care with a Network Doctor ASAP. We can recommend a docor in most areas of the US and around the world"...Dr. Stephanie Bridwell MS, DC, San Francisco CA, Chiropractor

What is it?

Participants from all around the world are here to share this healing, and self awareness weekend which has been attended by more than sixteen thousand people. Participation in The Transformational Gate™ demonstrates your commitment to life, and to a greater degree of wholeness and healing for yourself and the global community.

Attendees are here from all walks of life: lay people of all ages, chiropractors, body and social workers, and other health and wellness facilitators, all with their own stories, and their own dreams.

There are those who are relatively new to the process of personal transformation, new to the concept of being attentive to one's body, its tension, its ease, its movement, its stillness, its breath and its energetic flow.
There are those for whom this is their first Transformational Gate™, and for some this Transformational Gate™ may be their fifth or twenty-fifth program attended. Whether you are a veteran or virgin "Gater", we welcome you to this profound and powerful program
PURPOSE:
The Transformational Gate™ Seminar is an educational, experiential weekend designed to help you develop lifetime tools for greater awareness of yourself, your tension and ease patterns, and your bodymind's underlying rhythms and needs. This will assist you in developing a positive experience with your own self- correcting energy dissipating systems resulting in enhanced spinal and nerve system integrity, insight and well being. The Gate nurtures your awareness of your inter-connection with the web of life, assisting you in your journey.

The workshops at The Gate are designed to improve your attentiveness to your inner wisdom. We have found the experience of "awakening" in a group environment facilitates personal healing. The direct and indirect results of The Gate support your advancement in Network Care, and have many self healing benefits including increased self correction and self regulation of spinal subluxations
Through our own healing we become more compassionate towards ourselves. Through our compassion for ourselves we can be more available to others. Through our heightened participation with ourselves, we more fully participate with others in the shared experience of healing. This accelerates the healing process for all in attendance.

THE FORMAT:
All Gate participants are assigned to either of two groups (A or B). When group "A" is in the "Network" room, group "B" is participating in a workshop, and vice versa. The workshops coupled with the Network sessions are synergistic, each adding to your Gate progress.

Dr. Donald M. Epstein, who is the founder and developer of the Network Chiropractic, Network Spinal Analysis™, and Somato Respiratory Integration™ methods, will present lectures at the Friday and Saturday evening programs and at the Sunday commencement program.

The Friday and Saturday evening programs also include entertainment and participatory programs such as music, songs and dance, or audio visual presentations. For program times and locations , please refer to the Gate schedule.

Due to the unique nature and needs of each group, the times of the individual sessions and programs may vary slightly from your printed schedule. Please allow yourself to surrender to the flow of the weekend as this too is part of the healing process.

We have prepared a special "travel card" for each gate member. When you enter the "Network" room for your group session, please pick up your card from the table outside the room, and hand it to the staff doctor assisting you that session. Please place a fresh piece of face paper on the entrainment/adjusting table. At the completion of your session, he or she will initial your card and make notations. Please deposit the card in the box provided outside the room. The travel cards will be alphabetized, and placed outside the room for your next scheduled session.

You are invited to, but not required to, participate in all of the sessions and programs available for the members of your group at the Gate.

Exciting Promising Research- NSA and Spinal Cord Injury!!

Surface Electromyography in Network Spinal Analysis
This research, which involves human subjects, has been approved by the
University Park Institutional Review Board (IRB)
of the University of Southern California
(case USC UPIRB #01-01-009)

Network Spinal Analysis (NSA) is a technique through which the practitioner applies light pressure at precise points along the spine closely correlated to regions where dural attachments to the bony vertebrae and contiguous structures have been demonstrated. Although patient specific, within one to three months of care, the spine exhibits a spontaneous rocking motion which is not initiated voluntarily, but can be voluntarily ceased. Retrospective and longitudinal studies have indicated that the benefits of this type of care include enhanced flexibility and physical stability of the spine. This type of care also appears to relief adverse mechanical tensions in the spinal cord. Adverse Mechanical Tensions in the Central Nervous System is a theory developed by Alf Breig, a neurosurgeon from Stockholm, Sweden. Most importantly, this kind of care seems to provide the same kind of repetitive motion that has allowed, in the well publicized case of Christopher Reeve, some late sensory and motor recovery from spinal cord injury.

The theoretical foundation of Network Spinal Analysis is Alf Breig's theory of Adverse Mechanical Tensions in the Central Nervous System. In this theory, the attachment of the dura mater to the cervical vertebra creates pathological tensions on the cord in case of vertebral misalignment or postural problems. In Network Spinal Analysis, the dural-vertebral attachment is put to use to creates an oscillation that produces the same kind of repetitive motion that has been linked to spinal cord injury recovery in the well publicized case of Christopher Reeve. The oscillation is first localized to the vertebral area but soon propagates down the spine. Likewise, the attachment of the filum terminale to the coccyx in the sacral area also creates an oscillation that propagates up the spine. The uprunning and downrunning waves along the spine eventually yield the rocking motion of the spine typical of NSA. In addition to its potential applications to spinal cord injury recovery, in less dramatic cases it provides an intensive exercise for the back musculature, not reproducible by classical physio-therapeutical means.

During the rocking motion, a fair amount of surface electromyographic (sEMG) activity is present along the spine. The sEMG signals recorded at the cervical, thoracic, lumbar, and sacral levels show "bursts of EMG activity" appearing at random and lasting anywhere from a few seconds to a minute.
Early sEMG nonlinear signal modeling
Our early attempt to achieve a better understanding of this neurophysiological phenomenon has been to perform a nonlinear dynamical modeling of the sEMG signal during its "bursting" phase. The False Near Neighbor (FNN) approach, popularized in the chaos literature by Ruelle as a mean of estimating the dimension of an attractor, did not manage to reveal anything substantially different from a pseudo-random sequence. However, such proven techniques as the Nonlinear Canonical Correlation Analysis (CCA) and the Alternating Conditional Expectation (ACE) did reveal the presence of nonlinear phenomena and both techniques consistently pointed to a nonlinear dynamics of a dimension somewhere around 6 or 7. The CCA reveals a subtle, but definite (i.e., jumping from 0.1 to 0.8), increase of the 3rd, 4th, and 5th canonical correlation coefficients under nonlinear distorsion of the past and the future, while the ACE reveals some saturation in the regression functions predicting the future from the past.
Switching ARIMA modeling
Despite the nonlinearities in the sEMG signal, the possibility of a linear modeling was comtemplated, first because it could clarify the issue of the stationarity of the signal, and also because with the marked "bursts on top of background" signal aspect, it appeared plausible that the signal would be fairly well represented by two linear models (one for the burst, the other for the background) switching between each other. The background versus bursting discrimination was done on the base of the correlation and partial correlation sequences. Surprisingly, the background signal appears less stationary, as its correlation sequence does not decay as fast as it should be. The burst signal, however, appears more stationary, as its correlation sequence decays faster. A switching criterion, based on the correlation, was developed, and it appeared that the overall signal is fairly well modeled by the two linear models swithing among each other.
Spatio-temporal analysis of wave phenomenon
Next, a "spatio-temporal" analysis of the collection of signals recorded at various points was developed to determine whether a "wave" pattern traveling along the spine is present.

The first method relies on the Canonical Correlation Analysis of the past of the raw signal at one point S (the "source") and a time-shifted version of the future of the signal at another point T (the "target"). More specifically, from the canonical correlation coefficients, the Akaike mutual information is computed versus the time-shift and, if the mutual information shows a maximum for a time-shift t_s, it can be concluded that it takes an amount of time t_s for the wave to travel from S to T. From this analysis, it appears that the "source" is the sacral area, for indeed, the correlation analysis shows an increasing amount of time for the wave to go to the lumbar, thoracic, and finally cervical area. The fact that the sacral area appears the "source" is probably related to the attachment of the filum terminale to the coccyx. Conversely, the correlation analysis did not reveal such a consistent pattern when the cervical area is viewed as the "source." This is probably related to the fact that the attachment mechanism is by far more complicated in the cervical than it is in the sacral area.

Next, another simplified analysis based on correlation between wavelet subband signals was developed. The reason for focusing on some specific subband signals is that it appeared that some of the subband signals are noise related and hence irrelevant. That part of the signal the most relevant to the wave phenomenon is the D_8 subband signal of the Daubechies wavelet decompositon of order 3 down to 8 levels. The correlation between the subband signals turned out to be much larger than the correlation between the raw signals, hence a higher confidence in our assertion that there exists a nonvanishing correlation between the signals at various points, hence a higer confidence in the assertion of existence of a wave phenomenon.

The spatio-temporal analysis was conducted on a quadriplegic subject who had sustained the same kind of neck injury as Christopher Reeve and who had been under NSA care for about a year and who had recovered some control of his fingers and toes. The purpose of this study was to confirm the spinal cord injury recovery by spatio-temporal analysis of the sEMG signals running along the spine. The same analysis was also done on a base-line subject, in the same experimental setup and under the same protocol as the quadriplegic subject. The quadriplegic subject shows a weaker correlation involving the neck signals, as can be expected, but existence of a correlation between such distant signals as the sacral and cervical signals, with a 99% confidence level, reveals some recovery from the spinal cord injury.

April Events at Magnolia

Greetings from Magnolia Chiropractic,
I hope you are all enjoying the beginning of spring. As the weather gets nicer, we become inspired to get outdoors more and enjoy the many delights that living in the bay area has to offer.  

I want to remind you that regular chiropractic care is very effective in assisting you to stay connected to your body, the vehicle that carries you from place to place, this allows you to experience your hobbies, relationships, and health at OPTIMALLY!
One of the most exciting benefits of Network Chiropractic care is that it assists the brain in finding habitual patterns that may have worked for us a in the past, but may not be supporting who we are today. We get to rewrite that script with habits that support our growth and wellness.

Join us for:

Wine and Cheese party!! Please join us free wine and cheese bring friends and family. We will have a raffle and discounts toward the extraordinary care in our office.
Yoga Workshop- Free the Hips and Spine. Please pre-register space is limited to 7. Learn to free what is binding our hips and how to move the energy up through your spine. This will increase greater range of motion in hips and spine.

Free Wellness Talks-This month there will be 3 opportunities to learn more about how your care in our office. They are free to the community and all are welcome! Also, if you would like me to speak to your company or community I would love to. Please send me an e-mail to schedule a 45 minute talk with hands on experience. 

Some topics for talks that I do are:

· How to 'un-do' unhealthy habits and replace them with habits that support wellness
· How posture effects the way you perceive the world
· How stress is over 80% responsible for the chronic disease's most prevalent today and how to change that
· The many benefits of chiropractic care during pregnancy
· Chiropractic care and athletic peak performance
· How Network Care can reduce lost time from work and increase performance

Stroke Video-If you have not seen this yet, it is fascinating! It explains a scientist's unexpected experience of the interface between consciousness, awareness and the brain, when she suddenly found herself having a stroke. She explains the events in a way that anyone can understand. It will also help you understand how the brain and nervous system is involved during your Network care. http://www.ted.com/talks/view/id/229
