Joint derangements are about 80% of all orthopedic problems. Derangements are when a joint isn't sitting properly, leading to pain, stiffness, tightness, and so on. They are usually rapidly reversible! Unfortunately, people are often given structural diagnoses instead (here, it's an AC sprain) or told they have a muscle or tendon problem.
Since joint derangements comprise the LARGE majority of orthopedic problems, McKenzie experts are trained to look for them first. If a joint derangement is found, we use repeated movements to restore joint alignment. This patient had shoulder pain and limited movement following a car accident. One movement fixes her symptoms (bringing her arm across her body) - and one movement worsens her symptoms (bringing her arm back away from her body). McKenzie experts are trained to find WHICH movement is best for you and use that one movement as the treatment approach. -- Laura
I always write about not basing orthopedic treatment on imaging findings. We should also not base our treatment on clinical findings that appear to be structural without repeatedly moving the spine and/or extremity. Clinical orthopedic tests for the shoulder have been proven to be unreliable (for example, tests for rotator cuff tears, labral tears, impingement, or tendinopathy). McKenzie clinicians move your spine and extremities, looking for immediate cause and effect. Here, while it looks like the patient has a shoulder problem, when the McKenzie clinician moves her thoracic spine, it resolves. -- Laura
Tendon issues are unfortunately incorrectly diagnosed all the time. That is, issues that are not tendon problems are diagnosed as tendon problems. “Issues” and “problems” refer to tendinopathy, tendinosis, tendonitis, and tendon tears. We have hundreds of tendons in our bodies; they are pieces of tissue that connect our muscles to our bones. Those that get an unfair share of the blame are the four rotator cuff tendons in the shoulder, the two main tendon groups at the elbow, the Achilles tendon of the ankle, and the patellar tendon at the knee. This frequent misdiagnosis happens for two chief reasons.
One, tendon problems are common on images such as MRI so, in the absence of an expert clinical mechanical exam, the tendon is identified as the culprit simply because of a picture. The concern with this is that tendon problems are common on images such as MRI in people with NO pain or other symptoms. So if Sarah has a large supraspinatus tendon tear on her MRI and no shoulder pain and John has a large supraspinatus tendon tear on his MRI and does have shoulder pain, can you assert that the supraspinatus tendon tear is causing his pain? Not from that information alone, you can’t.
(Say your car starts acting funny. You open up the hood to take a quick look. You see a lot of leaves around the engine. Can you assume that the leaves are causing the problem? Or would your mechanic need to run some diagnostic tests? After all, we know that there are plenty of cars with leaves stuck under the hood that run just fine.)
The second reason for this misdiagnosing conundrum? Lack of expert clinical “mechanics.” When I first began as a physical therapist, if a patient came to me with shoulder pain (with or without an MRI report), I performed the orthopedic shoulder tests I learned in school. While there are several tests aimed at diagnosing a rotator cuff tendon problem, these tests are actually not very good. They can regularly be positive when something other than the tendon is at fault. If physical therapists, orthopedists, general practitioners, surgeons, chiropractors, athletic trainers, etc. are still basing their diagnoses (and subsequent treatment) on these tests, they are missing a lot of crucial information.
Once I learned during my post-doctoral coursework that other problems can mimic tendon problems, I began looking for these in the clinic. And, lo and behold, most of the time it is something else causing the patient’s problem. The top two problems that mimic tendon problems are misalignment in the spine joints whose nerves send signals to the area of the tendon (eg the neck) and misalignment in the extremity joint closest the tendon (eg the shoulder).
How do I diagnose a tendon problem then? These are my top two criteria:
In closing, don’t jump to conclusions based on an image or the location of pain. A lot of shoulder pain is coming from the neck or from a shoulder joint that is not sitting properly – not a rotator cuff tendon. Likewise, a lot of pain on the outside of the hip is coming from the low back or from a hip joint that is not sitting properly – not the gluteal tendon. Our bodies are beautiful in their intricacy and nuance, making my job as a mechanical therapist exciting. It is the ability to understand this nuance that makes a clinician effective at diagnosing and treating. --Laura
The article Arthroscopic subacromial decompression for subacromial shoulder pain (CSAW): a multicentre, pragmatic, parallel group, placebo-controlled, three-group, randomised surgical trial reveals no difference between the fake (or sham) surgery and the real surgery.
This type of shoulder surgery, know as subacromial decompression (SAD) is unfortunately still prevalent in the U.S. In this research study, both the sham surgery group and the real surgery group had something important in common: in both groups the shoulder joint was irrigated. Essentially the joint was power-washed. I believe this to be the key part of the intervention, the reason why both the fake and real surgeries provided the same results.
What I find in the clinic is that many joints have a piece of debris obstructing the joint's motion and causing pain. In the extremity joints this is thought to be a piece of fat, cartilage, bone, tendon, or similar. Of course, this can be effectively "power-washed" with repeated movement, too. My job is to find the movement that moves that piece of debris out of the way. My patient's job is then to perform that movement throughout the day and temporarily avoid movements in the opposite direction.
If you have been contemplating shoulder surgery, please read this study and/or contact me with any questions. Hopefully medical providers will no longer suggest this as an option. -- Laura
Joel Laing, a McKenzie specialist in Australia, gives a great demonstration of a rapidly resolvable shoulder issue - specifically, shoulder pain and loss of motion. The wonderful thing about the McKenzie method is that we are trained to actually LOOK for these problems. I was not trained to look for these problems during my physical therapy doctoral program. Now that I know how to diagnose these issues, most patients get better in a handful of visits or less versus weeks/months of PT.
In his case he needs to repeatedly move his shoulder backwards with his palm down. Typically when we find the healing movement the patient needs, the patient does a few sets per day. As Joel also points out, there are often certain movements that make the problem worse as well. While the shoulder heals, we usually ask the patient to avoid those motions for a few days if possible.
When it comes to shoulder pain, the top two diagnoses I see are:
1. The pain is actually coming from the neck or upper mid-back, so we treat the spine with movement and the shoulder pain goes away.
2. The pain is quickly resolvable with targeted shoulder movement (like in Joel's case).
Don't let shoulder pain affect your life; in the large majority of cases we can get it better fast. And don't get a diagnosis based on an MRI. Most people over 30 will have problems in the shoulder on an MRI. Since problems on an image (a torn labrum, degenerated tendons, a torn rotator cuff, bone spurs) are so prevalent in people without pain, what you see doesn't necessarily correlate with your pain. You instead need a quality McKenzie clinical exam. -- Laura
