“Neutral Balance Alignment Is Key To Becoming Pain Free!”™

I mentioned in previous posts how PNMT treats pain and dysfunction caused by muscular imbalances within the muscular-skeletal system. So, I thought I would include more detail regarding the distortions (misalignments) I look for⏤via the measurements I take⏤when treating clients, which ultimately has to do with the quote/slogan I coined 8+ years ago…

“Neutral balance alignment is key to becoming pain free!”™

When we are out of alignment, our body tends to spread distortions (via compensation) over as many segments as possible, which in turn spreads negative effects over multiple areas. My experience is that this usually stems from the hips, so my ultimate goal  during the first session (depending on my clients needs) is to get the pelvis back into neutral balance alignment.

I believe this is of great importance. In fact, when I get people back into alignment, this is when the magic really happens. To get there though, I take measurements before every session. I believe they are crucial for long-term health and wellness⏤it is about getting to the root cause; not just “rubbing where it hurts.”

Because most of my sessions last only one hour, I typically start with a select few based on my experience of what has worked over the years. If need be, I go from there considering we are all different, and our bodies respond differently as well.

The first thing I look for is a shoulder height discrepancy, while my client is standing. I check to see if they are level; most times not. This misalignment in shoulder height usually presents itself as being superior and inferior; one shoulder high, the other low. This is not an ideal situation to be in, but unfortunately, it can be difficult to avoid based on the factors that cause misalignments to begin with (more detail on that subject in another post). The good news is that this high/low discrepancy is usually an easy fix⏤one that I find most are unaware of for one reason or another.

The next thing I look for, while my client is still standing, are distortions in the pelvis. Distortions may include obliquity (high/low), torsion (twisting), anterior/posterior rotation (rolling forward/backward), etc. It could be one distortion or a combination of two or more. I also look at the knees⏤for more reasons than one⏤but specifically for confirmation of torsion.

Next would be to have my client lie on the table⏤on their back. From here I check the pelvis again; looking for more confirmation of what I saw while they were standing. I then look at the leg length. More times than not, there is a “long” leg⏤or “short” if you prefer to look at it that way. This also is not an ideal situation, but usually an easy fix if it is a functional leg length difference as opposed to a structural leg length difference. (It is my understanding that an x-ray of both legs with actual measurements of bone length, for comparison, is the only way to determine 100% if it is structural. And, of the 700+ people I have seen, a handful of them possibly had a structural leg length difference based on additional measurements I took.)

There are many other measurements in PNMT that are important indicators as to why something may be happening, but this is where I start… And they are well worth the few minutes it takes before I actually treat the muscles.

As always, I hope you find this information informative!

The Sciatic Nerve

I’ve had many clients come to me over the years requesting help with sciatic-type pain; either after having been diagnosed with “sciatica” or from assuming that it could be such. Unfortunately, it’s been made very clear to me that many people—the healthcare industry included—aren’t aware that discrepancies in certain muscles could mimic sciatica. I’m not at all saying that true sciatica couldn’t be the case, but my goal is to provide you with additional information to consider when it comes to the sciatic nerve, the muscles around it, and how PNMT can help you to become pain-free. First I’ll start off with the anatomy and then I’ll go into other details.

The sciatic nerve, which is the longest nerve in the body, is actually comprised of two nerves—tibial and common fibular (a.k.a. common peroneal)—which splits into two divisions, usually at the knee. Per Tortora & Derrickson (11th Edition), the nerve root origin is as follows…

  • Sciatic: L4, L5, S1, S2, S3
  • Tibial: L4, L5, S1, S2, S3
  • Common Fibular: L4, L5, S1, S2
    * (Click here for a dermatome chart: dermatome meaning the area of skin that provides sensory input to the central nervous system.)

As the sciatic nerve descends down the thigh, it sends branches to the hamstring muscles and the adductor magnus. At the knee, the distribution to additional muscles is as follows…

  • Tibial: Gastrocnemius, plantaris, soleus, popliteus, tibialis posterior, flexor digitorum longus, and flexor hallucis longus. It then divides into the medial plantar and lateral plantar branches:
    – Medial Plantar: Abductor hallucis, flexor digitorum brevis, and flexor hallucis brevis.
    – Lateral Plantar: Quadratus plantae, abductor digiti minimi, flexor digiti minimi brevis, three lateral lumbricals, dorsal interossei, plantar interossei, and adductor hallicus.
  • Common Fibular: Divides into the superficial fibular and deep fibular branches:
    – Superficial Fibular: Fibularis longus and fibularis brevis.
    – Deep Fibular: Tibialis anterior, extensor halluscis longus, fibularis tertius, extensor digitorum longus, and extensor digitorum brevis.

What could happen when the sciatic nerve is affected? Well, here’s what Tortora & Derrickson stated in their 11th Edition book…

Sciatic nerve injury, the most common form of back pain, is caused by compression or irritation of the sciatic nerve. Pain may extend from the buttock down the posterior and lateral aspect of the leg and the lateral aspect of the foot. It may be injured because of a herniated (slipped) disc, dislocated hip, osteoarthritis of the lumbosacral spine, pressure from the uterus during pregnancy, inflammation, irritation, or an improperly administered gluteal intramuscular injection.

To take it a step further and per my Precision Neural Mobilization training manual, a normal response from the sciatic nerve during a deep stretch, for example, could result in a sensation down the posterior thigh which may extend into the calf and foot. On the other hand, there are indications and causative factors that could result in abnormal responses. They are as follows…

Now back to some muscles and PNMT….

The gluteus minimuspiriformis, and hamstrings are a few muscles that can mimic sciatica. Trigger points (click here and here for previous posts on TrP’s—and please note that the muscles below, in bold, link to webpages that show TrP referral patterns) in the gluteus minimus can refer pain all the way down the side of the leg; usually stemming from the anterior fibers. TrP’s in the piriformis can send pain from the buttocks down the back of the thigh; however, the pain doesn’t go past the knee—it is also well known for its ability to entrap the sciatic nerve, so any tightness will produce sciatic symptoms. TrP’s in the hamstrings can also send pain down the back of the thigh. Travell reports that there are “rare” cases where the sciatic nerve is entrapped between two heads of the hamstring attachments on the ischial tuberosity; however, this study by Kari Saikku, Jarkko Vasenius, and Pekka Saar from the University Central Hospital in Helsinki, Finland found that this sort of entrapment “is not extremely rare.”

At the end of the day, muscular discrepancies within the muscular-skeletal system can in fact mimic sciatic-type symptoms—and I want you to be aware of this, especially if you have tried every other option out there to no avail. There are more holistic and non-invasive approaches to treating pain and dysfunction, and PNMT is a prime example. By taking just a few measurements to see how a person’s body is aligned, a trained therapist can ascertain what muscles are pulling where, and treat the affected muscles to help the individual to become pain-free again.

Sounds awesome, doesn’t it?

As always, I hope you find this information informative… And more importantly, HAPPY NEW YEAR!

The QL: Another Player In Back Pain

In a previous post, I went over the psoas major and how it is a major player in back pain, so today I thought I would go over the QL—the quadratus lumborum, which is a common source of low back pain. Before I go on though, let’s go over the anatomy…

THE ANATOMY (per Tortora & Derrickson, 11th edition)
Origin: Iliac crest and iliolumbar ligament.
Insertion: Inferior border of 12th rib and first four lumbar vertebrae.
Action: Acting together, pull 12th ribs inferiorly during forced exhalation, fix 12th ribs to prevent their elevation during deep inhalation, and help extend lumbar portion of vertebral column; acting singly, laterally flex vertebral column, especially lumbar portion.
Innervation: Thoracic spinal nerve T12 and lumbar spinal nerves L1-L3 or L1-L4.

The QL is a very strong lateral flexor and lateral stabilizer of the trunk; working synergistically with the psoas—on the same side—in lateral stabilization. It also assists the multifidi, erector spinae, and serratus posterior inferior in extension.

So, how do you know when the QL could be influencing back pain? Well, here are a few indicators for treatment…

  • Persistent pain, even at rest
  • Back pain after a violent sneeze or cough
  • Great pain when turning from one side of the body to the other while in bed
  • Excruciating pain when laterally bending or during forward flexion
  • Pain when standing; however, putting bilateral pressure above both iliac crests lessens the pain
  • Hyperlordosis is present.

If you experience one or more of the aforementioned, there is a good chance the QL is a player in your back pain—low back, specifically.

As always, I hope you find this information to be informative!

The Psoas Major: A Major Player In Back Pain

Have you ever had back pain or know someone who has? If so, this post is for you, my friends!

There are many muscles that could cause back issues, but today I’m going to focus on just one, that being the psoas major; mainly because I’ve come across too many new clients whom never had them treated before… And this surprises me. Another reason is because I’ve noticed that many people think that only back muscles should treated because it’s their “back that hurts”. Believe it or not though, there are muscles in the front of our body that have an effect on back pain as well. Before I go on though, let’s go over the anatomy…

THE ANATOMY (per Tortora & Derrickson, 11th edition)
Origin: Transverse processes and bodies of lumbar vertebrae.
Insertion: With iliacus into lesser trochanter of femur.
Action: Psoas major and iliacus, acting together, flex thigh at hip joint, rotate thigh laterally, and flex trunk on the hip.
Innervation: Lumbar spinal nerves L2-L3.

NOTE: Some people refer to this muscle as the “iliopsoas” because the psoas major and iliacus share a common tendon and end-point, but they are in-fact two separate muscles, which is why I’m only going to refer to the psoas; however, they do work in-conjunction, in some circumstances.

The function of the psoas is to increase flexion of the thigh at the hip. It can either bring the femur towards the spine or the spine towards the femur; just depends on what movement is taking place. An example of when it would be active—or contracting—is when you swing your leg forward during walking or running. The psoas is also a strong lateral flexor and stabilizer of the vertebral column (ipsilaterally—same side); as in when you bend to one side or the other.

How do you know when the psoas could be influencing back pain? Well, let me share a few examples—which also happen to be indicators for treatment—with you…

  • You have back pain when lying on your back; without a pillow under your knees
  • You have back pain that is vertical, but is relieved when in the reclining position
  • You have difficulty straightening after prolonged sitting

Taking it one step further, let me share some additional indicators for treatment with you…

  • An increase—or possible decrease—in your lordotic curve
  • You stand with your weight off the affected psoas side
  • You have unexplained pelvic floor pain (neural entrapment issues)
  • You have rotational distortions of the spine (Scoliosis)
  • You have groin pain

Please keep in mind that muscles have synergists and antagonists, so even though you have this information at your fingertips, there are other muscles not mentioned in this post that can cause a person pain and dysfunction in the back; anywhere in the body, really.

As always, I hope you find this information to be informative!

IMPORTANT NOTE: The psoas is a deep muscle in the abdominal area and great caution should be of utmost concern when treating this muscle. I mention this because of the possible presence of an AAA—Abdominal Aortic Aneurysm—which would be a serious contraindication for treatment, due to the fact that it could have potentially disastrous consequences.

Muscle Contractions

In this rather lengthy post, I’d like to go over muscle contractions and their types; isotonic (concentric and eccentric) and isometric. However, before I delve into each contraction specifically, I’m going to start off by providing a very watered-down version of an anatomy and physiology lesson in regards to our muscular system from a cellular level. For the record, I am not an A&P professional… Just thought I would use this opportunity to brush-up on some facts that I learned back in ’06. In fact, I probably learned this sometime between ’90 and ’93, but who remembers such detail from almost 20-years ago and while in high school. Hahaha! 🙂

Skeletal muscle tissue—which produce body movements, stabilize body positions, store and move substances within the body, and generate heat—is made up of hundreds to thousands of cells, also called muscle fibers. Muscle fibers consist of sarcomeres, which are made up of thick filaments, thin filaments, and Z discs; among other things. In order for muscle fibers to contract, certain proteins must be present; two of those being actin and myosin. Check out this link for visual aids and here is where you can read more about this in detail.

Okay, enough A&P for now! I’m a layman so onward with layman terms regarding the functions of skeletal muscles, that being muscle contractions. While the muscle is under tension, it may shorten, lengthen, or remain the same…

Muscle contractions are classified as being either isotonic or isometric. An isotonic contraction (iso- = equal; -tonic = tension) happens when tension developed by the muscle remains almost constant while the muscle changes its length. These contractions are used for body movements and for moving objects. The two types are known as concentric and eccentric.

Concentric isotonic contractions happen when two ends of a muscle are brought closer together during the contraction. The muscle shortens and pulls on another structure, such as a tendon, to produce movement and to reduce the angle at the joint. An example of a concentric isotonic contraction is when one does a bicep curl. As the dumbbell is lifted up, visualize how the two ends of the bicep move closer together during the contraction. This is the simplest form of contraction and is usually the least problematic.

Now imagine one lowering the dumbbell after the bicep curl. It is with this movement that the previously shortened bicep now lengthens during the contraction, which is known as an eccentric isotonic contraction. The bicep in this example contracts so it can control the speed at which the dumbbell is lowered. Per Tortora & Derrickson, 11th edition, repeated eccentric isotonic contractions produce more muscle damage and more DOMS (delayed-onset muscle soreness) than concentric isotonic contractions.

Isometric contractions happen when a muscle contracts but the ends do not move at all, and even though they do not result in body movement, energy is still expended. Isometric contractions are vital because they stabilize some joints as others are being moved. They maintain posture and support objects in fixed positions. The perfect example would be me sitting at the computer typing this right now. I’m sitting erect trying to use good posture and my mid-back is starting to hurt… Ugh! My lower trapezius is sustaining a contraction—to hold me upright—and it is becoming too much. At no time have the ends of the muscle come closer together. Make sense? I bet all of you have experienced this at one time or another.

There is one more category that should be mentioned, that of approximation; the length-tension relationship. If two ends of a muscle are brought closer together, over time, the muscle will adjust its length to keep the same tension. While not a true contraction, it acts like one. This is the concept of Davis’ LawWhen two ends of a muscle are brought together, the pull of tonus is increased. When two ends of a muscle are separated, tonus is lessened or lost, thereby weakening the muscle.

The first part of Davis’ Law has to do with adaptive-shortening. Unless something acts upon the shortened muscle, it will remain in the shortened position and adapt that position as the new “normal”. It will then resist attempts to return to the old “normal” as it has forgotten what that position was.

The second part of Davis’ Law has to do with stretch-weakeness. Muscles are affected by either duration or magnitude. Stretch-weakness is definitely a factor of duration, not magnitude. Having a shoulder much lower than the other for a short period of time is not as powerful as having a small difference for a long period of time.

It is through this length-tension relationship that PNMT comes in handy. These discrepancies within the muscles can cause pain and dysfunction. That being said, proper measurement from a Certified Precision Neuromuscular Therapist can help verify whether your pain and/or dysfunction is caused by misalignment within the muscular-skeletal system.

I hope this information has been informative!
