The Importance of Performing the Lateral Step Down Assessment in Runners

4/28/2015

0 Comments

If there is one assessment that I perform in working with injured runners beyond watching them run, it is undoubtedly the lateral step down (LSD).  The LSD is a simple, efficient, moderately reliable, and relevant assessment that yields a wealth of information when considering the performance demands of running. It tells you close to everything a clinician needs to know with the exception of a runner’s tolerance to hopping, cadence, and breathing strategy. Since a good portion of running related injuries (RRIs) tend to occur during the stance phase of running, the LSD gives clinicians, coaches, and trainers with a window into any potential impairments that may negatively impact one’s running while possibly putting them at risk of injury.

Before conducting an LSD assessment of an injured runner, however, it is important to first understand that during the running gait cycle that knee absorption during the stance phase is upwards of 45 degrees of knee flexion. The examiner should therefore set the height of the step to ensure the performer cycles through the 0-45 degree range of knee flexion. Additionally, the performer should also be barefoot to eliminate the potential influence of footwear as a shoe with a heel to toe differential may disguise any dorsiflexion limitation (apologies for demonstrating with shoes in the vid below). From there, I typically demonstrate the movement to provide the runner with a model of performance before having them practice a couple times to get acquainted with the movement. Special attention should be paid to ensure that the foot of the stance leg is straight and at the edge of the platform while the great toe is pointed towards noon on an imaginary clock. The non-stance leg should be held in full knee extension while maintaining the foot in a level position. The hands should also be positioned on the pelvis to ensure that they do not augment the performer’s balance. I typically perform 5 repetitions per side. 

Prerequisites
1. Clear understanding of how to perform the test
2. Completion of the LSD on the non-involved extremity
3. Ability to fully weight bear through the affected extremity

Equipment
1. Stepper or platform with adjustability
2. Level surface/ground for the platform for rest on

Information that We Obtain from the LSD Assessment
1. Toe dexterity
2. Single leg postural stability       
3. Ability to progress the leg over the foot (ankle dorsiflexion)
4. Tolerance to eccentric and concentric closed chain contractions
5. Adequate hip and lumbopelvic neuromuscular control?
6. Breathing strategy

Possible Compensatory Strategies to Monitor
1. Excessive subtalar pronation
2. Dynamic knee valgus
3. Femoral internal rotation
4. Hip adduction/contralateral pelvic drop
5. Excessive hip flexion

Interview with Richard Severin PT, DPT on Cardiovascular Considerations in Working with Endurance Athletes

4/27/2015

0 Comments

 
This past Friday, I had the distinct privilege to do a Q&A session with Richard Severin PT, DPT, who is a future PhD student at the University of Illinois - Chicago specializing in cardiopulmonary and orthopedic physical therapy. I specifically reached out to Rich to have him share his perspective and advice in terms of what rehabilitation professionals, trainers, and coaches should be doing from a screening and safety standpoint in working with distance runners and triathletes. As you will soon discover, Rich possesses an incredible command of the field. Perhaps his only pitfall is that he is from Philadelphia (Im a Pittsburgh boy - cross state rivals). Although he is too humble to disclose this, Rich scored a perfect on his physical therapy board exam. Needless to say he is an incredible resource that will have a profound impact on the profession. Without further ado, Rich Severin folks...

The Case for Space in the Toe Box of Running Shoes & Beyond

4/21/2015

There are relatively pieces of footwear advice that I give to runners with absolute certainty. One of them, however, is the fact that we should always afford adequate space for the forefoot by selecting a shoe that provides appropriate width and volume at the level of the toe box to avoid cramming our feet. While I hate to use a diagnostic image of this nature as it may seem to be a scare tactic, I thought that it would make it readily apparent that runners should strive to take better care of their feet through ensuring proper fit. 

I gained first hand appreciation for the ill effects of running in a shoe that did not provide enough space for the width of my forefoot a couple years ago when I returned to visit my family in Pittsburgh over the winter holidays. In typical fashion, I went out for a mid afternoon with the only difference being that I was in a new pair of shoes. Despite initially feeling okay, I started to experience a sharp pain at the base of my second toe on the left side about five miles into my run. After stopping to loosen up the laces, which seemed to be a bit too snug, I tried running again only to find myself wincing with every step. Fortunately, I was able to make it home and was relieved to finally get out of my shoes and off my feet. Although the pain gradually subsided over the next few days while I gradually resumed pain free walking, I noticed that I had developed a toe gripping strategy on the left side (see video below) that most likely set in during that run as I was never aware of it prior to that outing. Over the next few weeks, I had to focus extensively on resolving this compensatory strategy of gripping my toes through practicing various toe dexterity drills before I was able to finally return to walking and running without issue.
  
So the next time you go to buy a new pair of shoes, make sure to select a shoe that is not only comfortable and defect free, but also that affords adequate width and volume in the toe box. Of equal if not greater importance, is to also select dress and casual shoes that do the same since we tend to spend a good deal of time in various shoes outside of our running footwear. Here's to foot health!

Good Ol' Running Stupidity Syndrome (RSS)

4/6/2015

0 Comments

 
Two weeks ago, I came down with a case of Good Ol' "Running Stupidity Syndrome," or what I refer to as "RSS."

It was a mild Sunday morning and I had no major commitments aside from writing training programs for coaching clients. So, I decided to go for a long run (10-16miles), which I often do every 7-10days. After my usual ten minute fitness walking warm up, I broke into a conversation pace run, which initially took me along Lake Washington Blvd before heading through the Arboretum near the University of Washington. Upon exiting the Arboretum, I arrived at the base of 24th Ave, which is a long hill (~1.5miles) that is relatively steep (~7-8% avg incline). 

Up to that point in my run, I was maintaining a solid clip before having to contend with "The Monster." While it's not the steepest hill in Seattle, it's definitely a long, arduous climb along uneven pavers from start to finish. Despite having done this run in the past, I never completed the entire hill in a continuous manner because it's a beast. For some odd reason, however, I was feeling motivated and courageous and decided to run the entire hill at a relatively fast pace as a test of mental fortitude. Amateur hour!

As I fought my way to the top of the hill, I felt a sense of accomplishment and was finally on the homestretch as the rest of the run was predominantly downhill or at least level. This was not my longest run in 2015, but the most challenging between hills and pace.

After arriving home, I took care of some errands and light yard-work before finally dialing things back. Early that evening, however, I started to experience pain and tightness along the inner aspect of my foot and ankle region just below the bony part of the inside of my ankle. Right then and there, it became readily apparent that I was dealing with a case of RSS. 

To offset my poor decision making, I was forced to rest the next 2 days (by some standards not classified as a "running related injury"). Fortunately, I was able to cycle, lift, and swim as these activities did not reproduce any symptoms beyond a 1-2//10 discomfort with a few lower body movements.

So, the next time you are interested in having an overly ambitious training session or happen to feel unusually motivated, air on the side of caution. Longevity in running demands consistency, sound decision making, time for adaptation, and understanding it as a skill. 

Onward!

3 Simple Reminders for Injured Runners

4/1/2015

0 Comments

 
Every day I have the privilege to work with injured runners, who are in distress over their inability to train in a consistent manner. In the vast majority of cases, most runners seeking my services have already tried everything under the sun (to no avail) as they desperately attempt to keep training before they break down, accept their situation, and come knocking on my door. Before delving in to my physical therapy evaluation, I always make it a point to first speak with them about their injury and unique presentation in an effort to help them reconceptualize their situation while mitigating threat to their livelihood as a runner. To this end, I thought it would be helpful to share three simple reminders that I often bring up in conversation while working with injured runners.

1. MOST RUNNING RELATED INJURIES ARE NON-TRAUMATIC
When considering the injury patterns among runners, the research clearly demonstrates that the vast majority of running related injuries (RRIs) are non-traumatic in nature. This is great news because it's not as if you were tackled and sustained an ACL injury or that you dropped a heavy weight on your foot. So put your mind to ease and realize that things are not that bad considering the fact that there was no overt trauma.  

2. THE BODY HAS A REMARKABLE AFFINITY TO HEAL -
As a runner, chances are that you are in relatively good health as a function of your training and active lifestyle. With that said, your body has a remarkable affinity to heal irrespective of your age. While some runners may possess certain co-morbidities that may delay the recovery process, most runners will rebound from injury in a timely manner provided that they remain pro-active, work with a running injury specialist, and make good decisions during the recovery process.

3. RUNNERS ALMOST ALWAYS RESPOND TO CONSERVATIVE TREATMENT
In providing care for hundreds if not thousands of injured runners at this point in my career, I've never personally worked with a runner, who went on to require surgery to address a RRI that was non-traumatic in nature. This is good news provided that you connect with a rehab professional, who specializes in managing injured runners and prepares you for a safe return to training. If surgery, pills, and injectables are offered as a viable solution or long term fix, make sure to get a second opinion. While such measures can provide short term relief, they typically worsen the situation and only serve to prolong an otherwise timely recovery.

See you on the streets!
