Plantar Fasciitis! Run through or rest? Insole or shoe recommendations? Healing or prevention tips?

Ugh! Plantar Fasciitis. One of my least favorite injuries to see coming in my doors as a therapist.  Encouraged yet?

Plantar Fasciitis is a tough injury to deal with and overcome. I look at individuals with plantar foot pain near the heel is two categories: acute or chronic. Management is somewhat dependent on which category you fall into. The biggest difference is that if it is acute (short-term … let’s say <6 weeks old), you want to do everything in your power to stop it from getting worse right now! I’ll outline a few recommendations below. If it is chronic, there are some recommendations for things that might help depending on you as an individual. It often seems that each individual has a pretty specific response to all the possible interventions. Again, I’ll outline some recommendations below.

Plantar Fasciitis – What is it?

It is basically an irritation of the soft tissue along the bottom side of your foot. In particular, the heel is often involved. Fascial tissue is a thick tissue that is somewhat a middle ground between ligaments (firm, lacking mobility, meant to hold in place) and muscle (pliable, mobile, meant to move). In the foot, it is a thick tissue that covers primarily the toe flexors (curling). In a true “acute plantar fasciitis”, there is swelling in that heel area that can often be managed and certain techniques that can help it. In a “chronic plantar fasciitis” it gets trickier because I don’t really feel like we in the medical community know exactly what is going on …

There are multiple theories as to what is happening in Plantar Fasciitis, and I’m not too convinced of any of them. The traditional you will hear about is that there is scar tissue and restrictions built up in the tissue along with tightness. This theory leads to recommendations of stretching and of typically painful massage treatments on the bottom of the foot. I’ve used (and currently use) techniques based on this theory and have had some success … other times, it doesn’t seem to help much. Another theory is that the pain is related to a movement pattern fault. Basically, this theoretical standpoint would be that there is a strength or mobility issue somewhere likely in the foot, ankle, knee, hip, or back that is causing things to move differently than designed or placing more onus on the foot to handle the workload. This results in foot pain that could be related to any myriad of other things going on. I tend to gravitate toward this theoretical standpoint, but it is pretty wide open to interpretation.

Ultimately, I use the term Plantar Fasciopathy or Plantar Fascial Syndrome. Any time you hear -opathy or syndrome, you can basically assume that we in the medical field are saying “I don’t know”. I have some ideas to what is going on, but ultimately would not settle on any one thing being the ultimate definition.

So that’s what it is … kind of.

DOC TALK – Pain and Fatigue Science –> Implications for Running: Part 3 – Stress/Emotions/Memories

Let’s paint a picture of a pretty common scenario:

  • You have a high intensity speed workout or long tempo session planned for early evening
  • You slept in this AM to get a bit more sleep and rushed around to get out the door to start your work day. Work was a grind today with long hours and big projects that seemed to go nowhere. Then, right before leaving your boss called you in to talk about some underperformance on one of those projects. Finally, you get to go home … and really need that workout tonight
  • You quickly get your running gear on because you know you need to get that run in to relieve stress. Working hard sounds appealing too, so you are glad that it is a workout night. You do your warm up and feel a bit sluggish and bogged down but okay to continue
  • You start your workout, and you can barely hit your mark on the first and second rep, and it just goes way downhill from there. Instead of feeling refreshed after that hard workout, you are drained even more and mad that you couldn’t hit your goals again.
  • What a waste of a day!

Anything like that ever happen to you?

Why? Why were you not able to perform like you “should have been able to”? Let’s assume you weren’t overtrained, you weren’t injured, sleep had been good, and you were in good physical condition for this workout. So, what happened? Why were you so sluggish?

Central Governor - Fatigue

 

Likely, your emotions and stress were playing a big role in what you were feeling. The big increase in stress combined with other factors to influence your brain to produce a stronger fatigue response than typical. And then you bombed your workout just like you bombed your day :(

Today, we will spend a little bit of time exploring how emotions, stress, and memories can influence our brain and, therefore, influence our fatigue response during running.

DOC TALK – Pain Science and Fatigue Science –> Implications for Running: Part 1

Fair warning: This will be the most “science-y” series of posts to date, so feel free to tune out to your regularly programmed blog reading if this is not for you :) Today, I am going to begin exploring the relationship between pain science and fatigue science and how that affects us as runners. So, a few disclaimers:

  • My goal is to take advanced human science and break it down to somewhat simple explanations … which means this is not going to give full justice to the entire concepts
  • This is complex science, so don’t worry if you are fully following along at all times
  • It might seem that this would only apply to “advanced” or “elite” runners, but it really is universally applicable.
  • I’m not sure how detailed I am going to get as I write this series of posts, so any questions or feedback would be great!

So, let’s start with the basics (and old models of pain science and fatigue science). These are things that we probably will all have at least a basic understanding of. To be clear, these principles still apply and are still accurate, but modern explanations of pain/fatigue take much more into consideration.

When you get hurt (i.e. step off a curb and sprain your ankle), you have an injury to your ankle that leads to a pain response. This process looks something like this:

Peripheral Governor - Pain

Now in older understanding, this is how pain would generally be explained. You sprained your ankle, which led to a myriad of chemical reactions and responses that fired certain neurons that led to your experience of pain. Torn ligaments, stretched muscles, swelling at the ankle all led to pain. Again, this is still mostly accurate. These changes do occur and do contribute to pain … but they don’t explain the whole story …

Fatigue science is very similar: when you are running, things in your body are changing, and old fatigue models looked something like this:

Peripheral Governor - Fatigue

So, the traditional explanation would be that you start running and have these physical and chemical reactions in your body. The biggie that people talk about is lactic acid buildup. This is a frustratingly misunderstood concept, but it is not my goal to change that rumor, as many others have (see Alex Hutchinson’s post here). Suffice it to say, often the thinking is that at some point enough chemical builds up and causes the muscle to stop working efficiently (hence, fatigue). Again, there is a certain amount of truth to this explanation … but there is more at work …
