Had a GREAT talk with yesterday regarding bike fit considerations for triathletes, especially triathletes with scoliosis or fusions.

One important difference between road bike and triathlon fit is taking into account the fact that the rider has to go on to do an entire run once they get off the bike. That often means putting a little less stress through the hamstrings so that they have the ability to generate the force we need on the run.

Check out my Youtube or Dr. Laura’s to watch the entire chat - we cover everything from leg length discrepancies to breathing on the bike!

Success in physical therapy looks different for everyone.

I’ve helped patients with each one of these goals this year. When it comes to PT, nothing is too simple or too complex - the only thing that matters is that the plan supports whatever that person wants to achieve.

If you’re a PT, make sure you’re listening to what your patients really want to accomplish.

If you’re a patient, make sure you’ve got a PT who understands and knows how to get you to where you want to go.

Here’s a hill I will readily and absolutely die on:

Clinicians- Your. Words. Matter.

We’ve all heard of the placebo effect. The nocebo effect is its opposite: it’s the occurrence of worse outcomes due to patient expectations.

And where do those expectations come from? Often, it’s from the language we as practitioners use.

Nocebo comes from that latin root of “I shall harm.” Our words, if not chosen carefully, can do exponentially more harm than good.

Telling someone they “have the spine of a 90 year old” or their knees are “bone on bone” creates a narrative that these things are permanent and the person is broken. Tell someone this sort of garbage enough times, and it’s no wonder they believe it.

We as physical therapists are uniquely positioned to be able to change these narratives. Because we get the chance to take those unhelpful comments and show people what their bodies can *do*.

🏋️‍♀️Sure you have disc degeneration, but look at how you can squat without pain.
🚶‍♀️Your ortho may have told you you needed a hip replacement yesterday, but you’re still walking 2 miles a day.
💪Sure your MRI showed a rotator cuff tear, but you are still in the gym doing upper body work without symptoms.

But, as they say, with great power comes great responsibility. Telling someone their form is “bad” or that deadlifts will hurt their back, or not to twist in order to protect their spine reinforces feelings of vulnerability and hesitancy.

Beliefs create outcomes.

So be intentional when discussing findings. Be impeccable with your words. Be the reason that the person in front of you believes in themselves today.

Look. Most of us wait to do *anything* until pain or restrictions physically prevents us from doing something we want to do.

But, the older I get, the more I realize a little mobility can go a long way.

Doesn’t have to be complicated, doesn’t have to be a lot. Just has to be some movement for your spine and body that you don’t otherwise access throughout the day.

Here’s my daily routine:

1️⃣Open books at the wall. Great for thoracic rotation
2️⃣Thoracic foam rolling with sidebending and rotation. Gets ¾ movements of your thoracic spine - extension, rotation, and sidebending
3️⃣Extension with cactus arms: focuses on thoracic extension

See a theme? My mobility work focuses on thoracic (midback) movement. That’s because that’s where I’m the stickiest from years of cycling and bending over OR tables and patients.

Your mobility work may look different. But if you’re looking for some ideas, this is a great place to start.
