Biking and spinning usually involve a lot of spinal flexion. That's not bad, per se. But part of having healthy joints is understanding what makes them healthy. Joint mobility is a big part of joint health.
Except for the lower neck, which is extended to look up, the mid back and low back are usually flexed forward with these activities. Sitting upright is of course an option on a bike, but when people are going for speed or effort, they tend to adopt a hunched forward posture. As I say over and over, maintaining full mobility in your joints is paramount to health. If your joints are consistently in one direction or one position - and rarely if ever get moved in the opposite direction - you are much more likely to lose range of motion. Be smart about your activities and your joint mobility and significant injuries can largely be mitigated. -- Laura
How do I increase a person's ankle dorsiflexion range of motion? There is no one way to fix a sign/symptom. I can name ten possible things I would do to increase a person's dorsiflexion depending on the source of the deficit. A sign or symptom is not a diagnosis. You diagnose the problem that causes the sign/symptom and provide the appropriate treatment for that diagnosis. It’s the same as with other medical problems. There’s not one way to relieve head pain nor one way to increase low blood pressure. You figure out the reason (the diagnosis) and address that.
I know I sound like a broken record, but people want to oversimplify orthopedics when it actually takes solid diagnostic skills to achieve effective care. If a patient of mine has decreased dorsiflexion, that is just one piece of data in isolation. Combined with the other data I obtain (verbally and physically) and combined with the response to repeated dynamic testing, that piece becomes more intelligible. If you think you simply need to stretch your Achilles to gain more dorsiflexion, by all means, go ahead. It will help sometimes, but it’s not high on my list of treatments I use to gain dorsiflexion. There are many treatments I use more commonly than simple muscle/tendon stetching. So the answer to how I increase dorsiflexion is: “It depends.” -- Laura
Joint mobility is an extremely important piece of data when diagnosing and treating orthopedic disorders. Even though testing a joint’s mobility is easy, it is rarely done well. While the length of a muscle may matter, the strength very rarely does. A tight muscle (which is rare) may reduce a joint’s range of motion in a specific direction (the direction in which the tight muscle is put on stretch), but weakness is rarely a factor.
A muscle would have to be significantly inhibited and/or significantly weak for the patient not to be able to achieve full active range of motion, especially with gravity eliminated or gravity assisted procedures. (Remember: muscle inhibition usually comes from a nearby joint or spinal joints.) Muscle weakness does not impact passive range of motion, which is when the joint is moved by something external (not internal muscle strength). If a joint doesn’t move well - passively and/or actively - my investigation starts with joints themselves (local and spinal). If that proves fruitless, only then will I consider that muscles are causing reduced joint range of motion. -- Laura
When clinicians think of joint mobilizations, they think of clinicians moving joints at the level of the joint with their hands, which is true. This applies to the spine as well as the extremities. However, joints can be less-precisely mobilized - or moved - without that specific technique. In fact, if my goal for a movement is to move a joint versus, say, stretch something or strengthen something, I call it a joint mobilization. More loosely, we can just call it a movement or an exercise, but the intent is what matters - and the intent is to move the joint in a specific direction (its directional preference).
Sometimes the technique or the force applied by a clinician via mobilization or manipulation is necessary temporarily. But in the large majority of cases diagnosed as joint derangement, patients can learn how to mobilize themselves. In the trickier cases, we might have to figure out how to get assistance from some equipment at their home or from another person. When mobilizations (with or without a lot of force) are necessary as treatment, the results will be better the more often you do them. That said, in order to get those reps, it’s imperative we teach patients how to self-mobilize the best we can. The McKenzie method is predicated on teaching people how to self-treat in order to improve outcomes. My hands aren’t magic and I’m here to teach. -- Laura
It’s not uncommon that sleeping makes problems worse. That is, symptoms become exacerbated and/or movement becomes limited. Morning stiffness to a small extent is allowable when it comes to spinal flexion, but, otherwise, after being up and about for a few minutes, you should have the same amount of mobility you went to bed with.
During sleep, we often spend considerable time in one position without moving - whether we want to or not. It is my opinion that most orthopedic problems are related to movements and postures, so it makes sense that, just like with sitting or walking, sleeping postures can easily make people worse (or better).
If the thought process is that people need muscular strength to “hold” or “stabilize” joints in the right position, then there must be profound weakness if the simple act of sleeping causes joints to destabilize. Similarly, sleeping should not be aggressive enough to strain/pull muscles.
My thought process is this: I agree healthy joints should be able to withstand prolonged positions while sleeping, but I don’t think the answer is muscle-driven stability. And I don’t think muscles get pulled in our sleep. Benign positions like sitting or lying can indeed move joints - regardless of how much muscle is nearby. And these subtle changes can commonly cause symptoms. On the whole, strength is wonderful, but I believe we need to get the joint better first by moving the joint itself.
It’s true that spinal discs enlarge when we lie down to sleep, and that may be the sole factor why someone has more pain and/or less motion upon waking (vs related to any certain position). But even if that is the causative factor, then, again, I want to primarily address the disc (part of the joint) versus address the musculature around it. It’s also true that not all orthopedic problems are joint problems. Sleeping on a painful tendon can worsen symptoms, too. But most problems do have to do with joints - and addressing them effectively is important. -- Laura
If neck, mid, back, or shoulder blade symptoms are worse with driving or after driving, it’s worth considering your car posture. The same applies to symptoms anywhere in the head, face, shoulder or arm, all the way to your fingers. (The lower portion and bottom seat can play a role in low back and leg problems.) Most cars put the mid back in flexion and the neck in flexion and/or protrusion. In other words, the mid back joints are rounded and the joints of the neck are either bent forward or pushed forward.
If a posture has no effect on symptoms while you’re in the position nor after, and if your movement ability is not negatively affected, then there’s no problem. For a lot of patients with upper body complaints, though, posture in the car does warrant discussion. Many patients note driving is exacerbating and many patients spend a fair amount of time in their cars. The good news? With all of the patients’ cars I’ve assessed, adjusting the ergonomics of the car is easy and inexpensive. The theme is usually (if not always) to get the upper body straight, not flexed. The hardest part is for patients to get used to it - but that beats symptoms! -- Laura
Sometimes the neck isn’t just the neck. Movements affect joints of the neck in distinct ways. When you're at rest in sitting, for instance, the lower cervical is typically in flexion wheras the upper cervical spine is in extension. The designation into three separate sections (upper cervical, mid cervical, and lower cervical) is helpful. Retraction and extension target different parts differently, as do protrusion and flexion. Retraction-extension is not identical to pure extension. Lateral flexion in neutral is different than lateral flexion in retraction. And so on. As I believe most orthopedic disorders are fixed with specific movement, I am specific when it comes to finding that particular movement. -- Laura
So sit-ups flex your spine? So what? We flex our spine thousands of times a day and sit flexed an awful lot as well. As long as you (1) know how to discern if an activity (such as sit-ups) is harming you and (2) know how to correct it if it is, you are good to go. The best way to know if an activity is harming you outside of symptoms is ascertaining if it decreases your motion. (If we’re talking about the low back, that means flexion, extension, left sideglide, and right sideglide.)
I incorporate sit-ups into my workouts as well as other spinal flexion exercises. I like sit-ups with my legs straight and ones with my legs bent. But, what do I also do? I spend 10 seconds every day checking if I have my normal low back motion and also perform prophylactic movements. (I’m lying on my stomach propped on my elbows right now.) If I were just starting sit-ups, I would check right after to make sure they didn’t cause me to lose motion (they never did).
Are there certain things certain people can’t do? Of course. Sit-ups could hurt your back just like brushing your teeth could or a long car ride could; they’re not extra scary. By understanding the concepts of how to keep joints healthy, we don’t have to avoid nor fear specific exercises. I’m here to teach. -- Laura
If someone tweaks something, the question then becomes, what was tweaked? I find most tweaks occur in joints - not muscles, tendons, ligaments, labrums, nerves, or other structures. Think of a kitchen drawer not opening properly. Usually it’s the moving, connector parts that get tweaked, not the metal or the wood itself. The analogy is that joints are the primary moving units when it comes to our bodies.
Tweak also usually implies something not major, which I like. Problems that aren’t that serious can typically be fixed simply with movement. The final important point is that tweaks are not only acute events - long-standing symptoms can also be the result of a simple unrecognized tweak that just stuck around, never getting the proper treatment. These long-term problems often have fixes just like the recent tweaks that people do recall. -- Laura
Yes, some patients have problems that cannot be fixed with movement. But how will you know unless you test movements and interpret the effect? In almost all orthopedic cases, diagnosing should involve repeated movement testing. Morton's neuroma is currently diagnosed by imaging and provocation testing, but, as Michael David Post and Joseph R. Maccio's paper "Mechanical diagnosis and therapy and Morton's neuroma: a case-series" demonstrates, a repeated movement exam is needed to assess if patients will benefit from repeated movements.
If you take people with no toe pain and put them in an MRI, many will have neuromas. So we know they can be present without causing pain. When patients do have pain, then, we can't assume their neuroma is the cause. We need to investigate if the spine is the cause or the toe joint is the cause. Additionally, assuming a neuroma is causing pain still doesn't mean the patient won't do well with repeated movement treatment (but you have to find the correct movement).
What percentage of patients who complain of toe pain receive a competent repeated movement exam? How many with toe complaints will have a clinician investigate their lumbar spine? And what percent will even be recommended to see a movement-based therapist if the image shows a neuroma? If these three patients hadn’t resolved their problems in just a few visits with repeated movement, what types of therapies, injections, surgeries might they have had? In this case series, three patients with medically-diagnosed diagnosed neuromas abolished their toe pain with repeated movements, with those results remaining at one year. One patient required repeated movements of the lumbar spine (low back) and two patients needed repeated movements of the affected toe.
When it comes to movement testing, I believe in end-range repeated movement testing that investigates the relevant spinal segments as well as the relevant affected joint(s). This is the core foundation of the McKenzie method. Movement testing is not the same as orthopedic special tests or palpation tests or provocation tests. It means repeatedly moving a person in the clinic and at home and evaluating the effects if has on the person’s symptoms and mechanics. Looking at a picture and seeing if something hurts when you press on it is rarely enough. -- Laura
