Why physical therapy and yoga did not help your low back pain

In this article, we will examine physical therapy and yoga for people with low back pain. We will look at who these treatments will work for. We will also look at who these treatments can’t work for. We will also look at what people can do to make physical therapy work better and avoid unnecessary spinal surgery.

Physically therapy and Yoga do work for people. They do not work for everyone. For some, they can make the problem worse. This will be explained below.

When a new patient comes into our clinics with back pain and a history of physical therapy and other strengthening and stretching programs, they are often confused by the lack of results, we often hear:

  • “I have sciatica, after physical therapy, it was worse.”
  • “I tried physical therapy, it did not help.”

The Caring Medical experience is that the results of PT are often disappointing. Disappointing may not be the right word, perhaps dangerous would be better because failed PT is a primary reason for someone to be sent to unnecessary spinal surgery.

Physical therapy is a major component of the orthopedist’s “conservative” approach to low back pain relief. The Caring Medical experience is that the results of PT are often disappointing. Disappointing may not be the right word, perhaps dangerous would be better.

  • What makes physical therapy and its frequent companion treatment chiropractic manipulation dangerous is that they were given to patients who could not benefit.
  • But it wasn’t the physical therapy that was dangerous, it was the failure to achieve pain relief from it that created the danger for patients.
  • When these patients went back to the orthopedist and reported lack of success in physical therapy, chiropractic, massage, yoga, etc., the failure of these treatments were used as justification to send that patient to possible unnecessary spinal surgery. That is the danger of the failure of these treatments.

Who are these patients at risk for dangerous unnecessary surgery?

These are patients who suffer from pain caused by spinal instability from weakened and damaged spinal ligaments. For physical therapy, and as we will see later in this article, yoga and pilates, to work, a person needs strong spinal ligaments. Strong spinal ligaments provide resistance the spine and core muscles need to strengthen the core, provide stability, and make physical therapy more successful.

Patients who were at risk for physical therapy failure should be identified sooner.

A paper published in the Journal of Advancement in Medicine (1) by the Department of Physical Therapy, University of Utah, Salt Lake City, wanted to evaluate whether early physical therapy (manipulation and exercise) is more effective than a consultation where the patient were simply given education on rest, activity, and standard care options.

In this study, 207 patients with an average age of 37 were monitored and followed up at one year. Here are the study’s learning points:

  •  The primary outcome was that patients showed a positive change in disability, measured by the Oswestry Disability Index, after 3 months. That is the good news. Three months into PT, positive change. Now the bad news:
    • Early physical therapy resulted in statistically significant improvement in disability relative to usual care but the magnitude of the difference was modest and did not achieve the minimum difference considered clinically important at the individual patient level. (It didn’t help that much).
    • There was no difference between groups in the Oswestry Disability Index score at 1-year follow-up. (At one year both patient groups, those who had PT and those who did not reported the same results).
    • Results did favor early physical therapy at 3-month follow-up for outcomes of patient-reported success and overall health and fear-avoidance beliefs for work. (That they were getting treatment helped get people back to work, but it may not have been the treatment) as there were no improvements in scores for pain intensity or the Fear‐Avoidance Belief Questionnaire (a scoring system for people fearful of moving) for physical activity outcome at any time point. Because there were no changes in scoring, the patients may have gained improvement through the placebo effect.

The researchers, remember are physical therapists, they note: “The potential benefits of early physical therapy should be considered in light of the time and effort required to participate in physical therapy.”

The researchers were not trying to say physical therapy did not work better than educational guidelines, what they were trying to show was the physical therapy did provide benefits for many patients. Patients who were at risk for physical therapy failure should be identified sooner.

In the screening process of the study, patients with pain radiating into the knee area and clinical findings suggesting nerve root compression (suggesting lumbar radiculopathy, sciatica) were excluded, as well as patients who had a previous spinal surgery.

A summary video, Prolotherapy for back pain when physical therapy stops working

In this video, David N. Woznica, MD, offers a brief summary of physical therapy failures for back pain and how Prolotheray injections may not only help with the back pain but make physical therapy more effective.

Summary learning points:

  • We do see many patients who have had good benefits with physical therapy and chiropractic care. Unfortunately for many, this is short-term. The good news is however that something has helped these people and we can help those treatments work better and alleviate their back pain.
  • While there are different physical therapy techniques and chiropractic techniques, we do not explore all of them with the patient, we only want to explore those techniques that have helped the patient so we can expand on the successful side of treatments.
  • Generally, people who have pain when they sit for too long or bend in certain positions will be referred to a physical therapist. The therapist will then suggest a series of exercises to strengthen the spine. Why then would this not work? Many people have a diagnosis of discogenic pain. This means that the pain is suspected from coming from the discs, yet it may not be obvious on an MRI. In our clinics, we see that it is not discogenic pain, but spinal instability being caused by loose and weakened spinal ligaments. The spinal ligaments are strong rubber bands that hold your vertebrae in place and prevent herniation and bulging.
  • Here is why physical therapy will not be successful for some. Physical therapy needs resistance to build muscle strength. If the ligaments are damaged they do not offer the resistance the physical therapy needs to be successful.
  • We utilize Prolotherapy and Platelet Rich Plasma injections to strengthen and repair these ligaments. Both of these treatments are demonstrated and explained below.
  • Once the ligaments are strengthened and repaired we will often refer the patient back to physical therapy with a realistic expectation that the therapy will now be more successful for them. Sometime we will recommend exercise that they can do as well.

Physical therapy for lumbar radiculopathy and sciatica? Why won’t they work? The controversy surrounds ligaments and core muscles

There is much research surrounding low back pain and physical therapy and exercise. The above study was singled out because it appeared in one of the most highly regarded medical journals in the world, the Journal of the American Medical Association (JAMA), and an article on this study appeared in the October 14, 2015 edition of the New York Times. In that article lead author, Dr. Julie M. Fritz is quoted as saying: “Most treatments that are effective have only modest effects. The pattern of low back pain is one of recurrence and remission, and changing that pattern is a real challenge. There are no magic answers.”

And this is what we find at Caring Medical when taking a patient history. The patients will tell us their story of treatment, success, remission, new pain, sometimes worse pain, back to therapy, or to the chiropractor. They will repeat the cycle until such time as the cycle is broken by pain management medication therapy or a recommendation to surgery.

What they generally do not tell us is that they went to a doctor and that doctor did an examination on their back and hip area looking for instability caused by spinal ligaments and the accompanying muscle weakness, spasm, and low back pain.

Spinal instability = Ligament strength first then muscle strength

There are two sets of muscles in the body: mobility muscles and postural stabilization muscles.

  • Mobility muscles are important primarily for their ability to contract and create, manage, and move the large joints. The triceps and bicep muscles that move the arm and the tensor fascia lata, psoas and quadriceps muscles that move the leg belong to this first group.
  • The postural stabilization muscles are deeper muscles that contract as the mobility muscles move the joint and usually have proximal (center or core) attachments that remain fixed, either on the spine posteriorly (behind) or on the sternum and ribs anteriorly (in the front). They are the anchor when the distal or furthest attachments to the mobility muscles are moved.
    • These stabilizer muscles are often referred to as “core” muscles since they attach to the axial skeleton and pelvis, which are considered the foundation of the human body.
  • Thus, the two sets of muscles work together, with the stabilizing muscles contracting and stabilizing a person’s core as the mobility muscles move one or more peripheral joints. For example, when the tensor fascia lata and psoas muscles contract to move the lower leg, the contracts to hold the pelvis in place so it cannot move, thus stabilizing it so the two mobility muscles can move the leg.
The tensor fascia lata muscle, a stabilize muscles often referred to as “core” muscle since they attach to the axial skeleton and pelvis, which are considered the foundation of the human body.

The tensor fascia lata muscle, a stabilize muscles often referred to as “core” muscle since they attach to the axial skeleton and pelvis, which are considered the foundation of the human body.

The primary role of the core muscle systems in the lumbar spine and pelvis is to provide segmental control and dynamic stability to the spinal column it cannot be done without strong ligaments.

The lumbar region is well endowed with the core muscles, which play a role in the stability of the spine. These muscles—the abdominal muscles, the psoas major, and the erector spinae—are all actively involved in maintaining the functional stability of the lumbar spine in both upright and sitting postures. Their muscle action is especially crucial during the very high loading that the lumbar spine typically undergoes. Without these muscle forces, such large loads would cause disruptions in the lumbar vertebral column and likely result in spinal instability and severe pain.

  • The anterior core muscle group consists of four abdominal muscles that encircle the abdominal region and include:
    • the external oblique,
    • internal oblique,
    • transversus abdominis, and
    • rectus abdominus muscles.
  • The posterior core muscle group is further divided into superficial, intermediate, and deep subgroups according to their muscle length.
    • The superficial muscles are the longest and run vertically from the sacrum to the upper vertebral spine;
    • the intermediate muscles, of medium length, arise from the transverse processes of the vertebrae and attach to the spinous process of the vertebra above it;
    • the deep muscles are the shortest and connect adjacent spinous processes. These latter muscles move the trunk and back.
This illustration reveals the complexity of the back muscles. Back muscles and core muscles are a primary focus of physical therapy. Spinal instability, caused by spinal ligament laxity can cause vertebrae to move out of their natural positions and cause bulging and herniation. Even a single maligned vertebrae can impact and cause dysfunction throughout the spine and core muscle groups. This will make physical therapy ineffective.

Physical therapy will not make gains without without strengthened, repaired ligaments

  • Except for the lower back, muscles do little to stabilize the joints since their job is to move the joints.
  • Large muscles are necessary in the lower back due to the enormous forces that are transmitted to support the body’s weight; thus, the core musculature is an important part of maintaining spinal stability, but is not the most important part—strong ligaments are.
  • Ligament laxity is what causes spinal instability throughout the spine and neck, and Prolotherapy treatment for back pain (see video) is the primary treatment for restoring spinal stability, with core strengthening exercise playing a secondary role.
  • An injury to one section of the spine affects other sections but the action of the erector spinae muscles is also a contributing factor. The vertebral joints (hinges) in the spine are very close together and when one is loose, it causes increased forces on the next vertebral level, as well as a contraction of the erector spinae muscle, which then pulls on the vulnerable segment, causing it to become unstable as well.
  •  To be curative, the treatment for chronic diffuse spinal pain must be a comprehensive regimen of tightening all the “screws” on all the loose “hinges”. This is why Prolotherapy to the spine can involve multiple areas and many injections. If you do not comprehensively treat all the loose ligaments with Prolotherapy, the pain will likely recur.

Yoga works when there are strong ligaments, yoga will not help when ligament instability prevents muscles from getting needed resistance

Some patients with lower back pain have seen great results with yoga. Some patients have seen poor, none, or worse, results that caused greater injury to the low back. Why do some get benefits and others didn’t? How do some hurt themselves worse? The answer is ligaments.

Let’s first paint a picture by way of a comparison between yoga and physical therapy and the ligament problem.

  • If ligament damage and weakness are the problem, a patient trying yoga and physical therapy will find in most cases, neither will help.
  • If the patient’s ligaments are still strong enough and can provide the spinal and core muscles resistance, the spine will be stable enough for yoga and physical therapy to work and provide great relief.

Research that was published in the July 2017 edition of the Annals of Internal Medicine (2) helps us shed some light on realistic expectations for Yoga and Physical Therapy.

Coming from some of the best research universities in the United States, doctors from Boston University School of Medicine, Harvard Medical School, the University of Pittsburgh School of Health and Rehabilitation Sciences, and the University of Washington found:

  • “The yoga and physical therapy groups showed almost the same amount of improvement in pain and activity limitation over time.” (As I stated above, Yoga and physical therapy should work the same for the same patient).
  • “The improvements in pain and activity limitation in the yoga and physical therapy groups were also found at 1 year and were similar to each other.” (Again, Yoga and physical therapy should work the same for the same patient).
  • “Yoga did not perform better than education in terms of improvement in pain and activity limitation at 3 months.” (Yoga did not work better than simply educating the patient on how to handle their low back pain, similar findings were noted in the above study centered on physical therapy from the University of Utah. Again, PT and yoga should be just as effective or ineffective in the same patient. It is all about the ligaments).
  • “However, participants in both the yoga and physical therapy groups were less likely to use pain medications at 3 months compared with the education group.” (As noted in the  University of Utah, the patients were getting treatment, treatment in the short-term no matter the treatment will likely show improvements in patients who are hoping that the treatments will work. The placebo effect if you will).
  • “Other measurements (satisfaction and quality of life) were similar between the physical therapy and yoga groups. (Again, yoga and physical therapy should work the same for the same patient).

The portions of the above in quotations comes from the Annals of Internal Medicine, patient information recap of the study.

January 2017, a study lead by the University of Maryland published in The Cochrane Database of Systematic Reviews.(3)

The authors concluded:

  • “There is low- to moderate-certainty evidence that yoga compared to non-exercise controls results in small to moderate improvements in back-related function at three and six months.” (Again, yoga can be best effective when the spinal ligaments are strong. If spinal instability is the problem, yoga will not be successful for very many patients).
  • “Yoga may also be slightly more effective for pain at three and six months, however the effect size did not meet predefined levels of minimum clinical importance.” (Confirming again if spinal instability is the problem, yoga will not be successful for very many patients.
  • “It is uncertain whether there is any difference between yoga and other exercise for back-related function or pain, or whether yoga added to exercise is more effective than exercise alone.” (Again, yoga and physical therapy should work the same for the same patient).
  • “Yoga is associated with more adverse events than non-exercise controls, but may have the same risk of adverse events as other back-focused exercise.” (See note below on people overdoing it on weak ligaments).

In a commentary to the above study, researchers from the United States Department of Veteran Affairs and from Rutgers University published in the journal Explore August 2017 (4), their beliefs that yoga will provide benefits from some patients. This is explained in this statement:

“Even though the evidence was of moderate to very low certainty (that yoga worked for low back pain sufferers), given its relative safety, the trends toward positive results, and the high rates of chronic pain and opioid use, yoga should be considered as a potential approach to include as part of a patient’s care plan for non-specific chronic low back pain. Similar to non-yoga exercise, yoga helps bring movement into the body. However, yoga also supports the development of body-awareness and focus on posture and alignment, as well as assists with physical and mental stress, which may be particularly important in the management of chronic low back pain. “

Pilates works when there are strong ligaments, Pilates will not help when ligament instability prevents muscles from getting needed resistance

Pilates is an exercise program that concentrates on the deep stabilizer muscles of the core. Pilates, like physical therapy, like core stabilizing exercises, can only work when the ligaments of the spine can support the exercise activity and provide resistance so the muscles strengthen.

It is very rare to see research that says one form of exercise works and another does not. They either all work or they all don’t work. Studies supporting one form of exercise over another support this idea.

Here is the last paragraph from an August 2017 study in the Journal of Exercise Rehabilitation:

“On the basis of the present study it can be concluded that lumbar stabilization exercise, dynamic strengthening exercise and Pilates are beneficial in the treatment of chronic nonspecific low back pain for reduction of pain, improvement in functional ability, increase range of motion and improve core strength.

However when compared, lumbar stabilization proved to be more effective form of exercise than Pilates and dynamic strengthening for chronic chronic low back pain.”(5)

They all worked. One a little better than the others in this one group.

The point of this article is that Physical Therapy, Yoga, and Pilates will work better if strong ligaments in the spine are present to provide the resistance necessary to achieve gains

In this video, Danielle Matias, MMS, PA-C explains and demonstrates a Prolotherapy treatment into the lumbar spine.

Video Summary and Learning Points

  • Prolotherapy is multiple injections of simple dextrose into the damaged spinal area.
  • Each injection goes down to the bone, where the ligaments meet the bone at the fibro-osseous junction. It is at this junction we want to stimulate repair of the ligament attachment to the bone.
  • We treat the whole low back area to include the sacroiliac or SI joint. In this video, the patient’s sacroiliac area in being treated to make sure that we get the ligament insertions and attachments of the SI joint in the low back.
  • I’ve marked with a black crayon all down the midline of this patient’s back  and then I have a horizontal line drawn where her pain stops. This patient has a curvature of her spine, scoliosis, so it is important to understand where the midpoint (center) of her spine is. In this patient, we are going to go up to the horizontal line into the thoracic area which is usually not typical of all treatments.
  • It’s important to note that this particular patient is actually not sedated in any way so even though it is a lot of shots and a lot of injections through the skin which can be painful, patients tend to tolerate it really well the whole procedure goes relatively quickly
  • At 2:20 I’m just making sure that I get the sacroiliac or SI ligaments as well as the iliolumbar ligament to help strengthen the low back.
  • After treatment we want the patient to take it easy for about 4 days.
  • Depending on the severity of the low back pain condition, we may need to offer 3 to 10 treatments every 4 to 6 weeks.

Caring Medical and Rehabilitation Services research: Our paper “A Systematic Review of Dextrose Prolotherapy for Chronic Musculoskeletal Pain,” published in the journal Clinical Medicine Insights. Arthritis and Musculoskeletal Disorders made these observations supported by accompanying citations:

  • In approximately 90% of patients, low back pain is mechanical in nature, typically originating from overuse, straining, lifting, or bending that results in ligament sprains, muscle pulls, or disk herniation.
  • The popular understanding of back pain is disc herniation as a frequent cause, but to a much greater extent, ligament injury forms the underlying basis.
  • Ligaments hold the disc in place, and with ligament weakness, the disc is more likely to herniate.
  • Low back pain patients who remain symptomatic despite tailored physiotherapy are believed to possess deficient ligament strength in the rear elements of the sacroiliac joint, resulting in insufficient stability to permit effective muscle recruiting strategies.(6)

Without strong ligaments, physical therapy cannot work.

The entire content of this article is nicely summed up in these few words. “insufficient stability to permit effective muscle recruiting strategies.” Without the ligaments, physical therapy cannot work.

The next bullet point, from the same research, gives the solution:

  • Experimental studies have found Prolotherapy effective in stimulating the production of collagen fibers, thus strengthening ligaments.

In a separate study we published in the Journal of Prolotherapy,  we published these findings:

  • We looked at 145 patients, who had been in pain an average of four years and ten months, and were treated quarterly with dextrose Prolotherapy.
  • This included a subset of 55 patients who were told by their medical doctor(s) that there were no other treatment options for their pain and a subset of 26 patients who were told by their doctor(s) that surgery was their only option.
  • Patients were contacted an average of 12 months following their last Prolotherapy session and asked questions regarding their levels of pain, physical and psychological symptoms and activities of daily living, before and after their last Prolotherapy treatment.


  • In these 145 low backs, 89% experienced more than 50% pain relief with Prolotherapy;
  • more than 80% showed improvements in walking and exercise ability, anxiety, depression and overall disability;
  • 75% percent were able to completely stop taking pain medications.(7)

These patients were treated every three months on average.

In summary, when physical therapy does not work, then the person should consider Prolotherapy.
