Does Your Doctor Really Understand Your Level of "Physical Activity"?

I came across a study recently that came to a not-very-surprising conclusion: that a high level of leisure-time physical activity is good for your knee cartilage.

That’s nice to hear (again), but it’s hardly stop-the-presses news. Nor is it necessarily true without qualifiers. There is an appropriate amount of physical activity that’s good for knee cartilage, but you to make sure you get that amount right for you, especially if you have a difficult case of knee pain. Too much and you’ll further damage your knees.

What I found more interesting was this idea of “physical activity,” taken in its broadest sense. The study focused more on activities such as walking and Nordic walking, but “activity” can be almost anything: it’s crossing the room, kneeling to scrub the floor, walking to the mailbox, carrying your little niece on your shoulders. It’s all of that and much more.

This study got me thinking about something doctors and physical therapists usually don’t do: they don’t take anything resembling a comprehensive inventory of how you use your knees each day. Example: You have really bad knees and your doctor asks what sports you do. You say you don’t run or play basketball, but get in a few miles of slow walking each day.

Sounds great, right? So maybe your doctor writes down, “Sporting activity appropriate.” But what if you’re also lugging your two-year-old around all the time? That could be doing as much damage to your knees as playing basketball a few times a week.

In my book, I went into a lengthy criticism of a knee study that seemed to me to be a bit of a mess. One flaw concerned giving too much weight to how much time your knees spend in a certain kind of physical activity, like running or walking. That’s part of the picture, but it seems to me everything you do from the moment you wake up until you hit the sack at night is part of the picture. And if you’re not being asked about how you use your knees outside of sport, your health-care provider (or therapist) isn’t looking at the whole picture, but only at what might be a small piece.

One point I like to make about conquering knee pain is personal involvement in finding a solution. The experts are good, but they are limited: they only have a short time to spend with you, and there’s no way they can crawl inside your body and feel how your knees feel, and live with those joints for a few days to see how they’re being used, and how they’re irritated, and to what degree.

So I think it falls to everyone with knee pain to do this analysis themselves. Ask yourself, “How do I use my knees each day?” What knee-unfriendly things do I do? How much squatting, lifting, kneeling, carrying, walking? You may find activities in there you’re doing that you shouldn’t be – at least not until your knees are stronger.

Open Comment Forum Again, Your Turn to Speak!

I thought today that once more I'd turn over the mike to all of you. The open comment posts have turned into some of the best read recently!

Again, you're all welcome to discuss whatever you want. If, however, anyone is searching for a topic, here's one that's a bit different: What are some of the best resources you've found online that have helped you with your knee pain (this website excluded of course; I'm not scrounging for compliments :))

Otherwise, hope you're all well, and looking as forward to the end of winter as I am (okay, none of this applies to our friends south of the equator; forgive me for being Northern Hemisphere-centric). I want to ride my bike again but it's hard when the temperature is 16 degrees at six o'clock, like today. Cheers!
