Nerves - like discs - often inspire fear in people. Yes, they can be injured just like other structures, but nerve problems are not necessarily more severe than other types of orthopedic problems.
We temporarily impact nerves all the time, stretching them and compressing them just like other structures. You bang your funny bone and your arm throbs for a minute. You sit on your leg and your leg and foot go to sleep for a few minutes. These examples teach us both how resilient nerves can be and how irritation and compression can create symptoms. (Perhaps even more importantly, they teach people that nerves can send symptoms away from where the root of the problem is.) Understanding how your body works is the first step in mitigating fear when something goes wrong.
Most nerve irritation problems I see stem from the nerves being irritated near the spine. These irritations create variable symptoms; it can feel like the numbness and tingling you feel when you compress a peripheral nerve in your arm or leg or it can be pain, tightness, heat, etc. Nerves serve the very important role of relaying information and sensation throughout your body, and, like other structures, they can usually heal given the right environment.
I sat at a performance years ago with my legs crossed for at least 30 minutes without moving. When I went to get up I almost fell because there was little power in my ankle muscles nor was there great sensation. I realized what had happened and I wasn’t afraid. On the contrary, I thought it was really fascinating how I couldn’t lift my foot up at all. I expected it to resolve in 15 minutes or so and it did. I often remember that incident when I happen to be sitting with my legs crossed, the back of one knee over the other.
Big picture: don’t be afraid when it comes to nerves. If they get compressed or irritated wherever in the body, most of the time, by removing the compression (typically with movements) and by giving it an environment to heal, it will heal. To be clear, many neurological symptoms (having to do with nerves) are not orthopedic in nature, but they too can usually be fixed if you get the correct diagnosis. --Laura
The study, “Prevalence of Optimal Metabolic Health in American Adults: National Health and Nutrition Examination Survey 2009-2016,” was published online Nov. 28, 2018 in the journal Metabolic Syndrome and Disroders. I propose that similarly few Americans are musculoskeletally healthy.
While there may be some debate over the absolute best criteria to use to determine metabolic health, the five used in this study are clearly important. For instance, some clinicians argue that insulin level is a more significant barometer of health than glucose level.
For musculoskeletal health, as I have written before, I propose that the criteria are: full joint mobility; full strength; full nerve extensibility; and full, pain-free function. Function means being able to do what you want to do with your body and not being limited by musculoskeletal problems. (Be aware: not being able to do something can be limited by fitness, not problems.) Yes, full, pain-free function is less objective and more individual than the other three metrics, but it is still relevant and critical.
Could you make the argument that being able to walk 1 mile in under 15 minutes should also be a criterion? Or that normal musculoskeletal health means you should be able to get up from a chair without needing your hands? Sure. Those demands, though, usually require that you meet the basic criteria. There’s certainly room for debate, and we do have valid tests that measure people’s ability to do things like this.
However, whichever metrics we use - the simple ones I propose or more involved ones - it’s clear from my experience (ten years working in orthopedics) that not many Americans would fit the criteria for being musculoskeletally healthy. -- Laura
