The Rise of Tendinosis

I know these days we all get lost surfing the internet.

A site I visit, and visit to often, is Pub Med.

Pub Med is a site that is full of the latest and oldest research.  I always go to take a look at what is new when it comes to exercise and injuries.

I know, kind of strange.

One injury I have been seeing more of is tendinosis.

Just last week I got an email from a fitness professional that does group fitness classes that has had 5 months worth of Achilles tendinitis issues from all the step classes she has been doing.  My guess, it is Achilles tendinosis.

So, I will call the increase in tendinosis as Prediction #7 in Exercise Rehabilitation 2011.

Tendinitis versus Tendinosis

The first step is to define what tendinitis is and tendinosis is.

Better yet, I found a table that describes it much better than I could.

That is a great table.

Make sure you read it.

If we had to simplify things, we would say tendinitis is damage to the tendon with inflammation, and tendinosis is damage to the tendon with no inflammation.

I know with myself I have a chronic Achilles tendinosis that occurred during a hike in Ecuador.

Yes, in Ecuador.  I was hiking up a mountain and my boot got stuck in the mud.  As I pulled it out, I felt a twinge in my calf.

When it acts up on me, I do a few weeks of specific Achilles tendinosis exercises, and it feels better.  The pain vanishes, I get my strength back, and I can go back to running.

Most Common Tendinosis

Tendinosis can occur anywhere in the body, but the most common areas are in the ankle, knee, and shoulder.

Here is a specific list of common areas that tendinosis occurs:

  • Achilles tendinosis
  • Supraspinatus tendinosis
  • Patellar tendinosis
  • Subscapularis tendinosis

What Can You Do About Tendinosis?

As usual, exercise is the answer.

There is debate on specific protocol, but I have a number that I have been using with myself and my clients with success.

Over 2011, I will chat more about it.

As with all injuries, make sure to have it assessed, get an accurate diagnosis, and get clearance to start an exercise rehabilitation program.

Before I wrap up, here is one of the exercises I do:
