I have posted on the perils of patello-femoral pain in the past on this blog.  Today, I will share how surgery to fix one knee problem may lead to a new problem.  For privacy reasons, I will refer to my client as player x. 

History: Player x is a 15 y/o healthy female soccer player who suffered a lateral menscus tear in the summer of 2009.  She had arthroscopic repair followed by a brief stint (4-6 weeks) of rehab.  Surgery went well, but she did not regain full extension in rehab (she has about 5 degrees of hyper extension naturally).

Prior to fall high school season, player x came to me for sport reconditioning.  She had obvious quad atrophy (particularly the VMO) and lacked speed and explosiveness.  She worked with me 1-2x/week for 4-6 weeks and made good progress but did note some mild persistent soreness in her knee.

She played the entire fall season without injury/limitation but continued to have the same mild persistent knee pain.  The first week she began club practice (fall high school season had ended), her club coach had the players do a lot of plyometrics.  The exercises did not seem hazardous, but player x immediately had a significant increase in knee pain.

Her mother contacted me and she recently came back in for an assessment.  Ironically enough, her single leg squat and single leg broad jump were within 90% of her uninvolved leg.  However, she had mild swelling, Quad atrophy (about a 1 1/2 inch deficit) and she had significant pain with lateral movement to the side of her involved knee and could not decelerate without pain.

Hmmm…..   So what is the issue here?  After carefully evaluating her and performing functional testing I was able to rule out quadriceps tendinitis.  Her pain occurs primarily at or beneath the superioir and lateral portion of the knee cap at 30-40 degrees of flexion when she is weight-bearing.

I am fairly confident she has patello-femoral joint irritation with excess compression along the lateral facet.  Why?

1. Perhaps the slight extension deficit allowed her to run more on a slightly bent knee (more PF force)
2. Weak VMO is overpowered by the vastus lateralis creating abnormal lateral translation of the patella
3. Pain is worse with deceleration and eccentric strength exercise going past (greater quad pull and patellar compression occurs with these activities)
4. Pain with lateral movement and change of direction suggest lack of proper medial stability and dynamic control of femoral internal rotation which would subject the kneecap to abnormal joint reaction forces especially laterally where her pain is felt
5. No pin point tenderness consistent with soft tissue inflammation

The entire scenario has likely been perpetuated by the volume of training/running in soccer and was then exacerbated by the plyometrics.  She compensated and ignored the mild pain all fall, but the knee finally reached a breaking point with the plyos (keep in mind she did no plyos in the high school fall season).

I see patello-femoral pain all the time in female year-round soccer players.  What is the solution?  Stay tuned as I will share more details about patella balancing training and my corrective exercise program for player x in the next post.

Ever feel the tightness or ache deep in the shoulder during or after a series of bench press sets?  I must admit I LOVED doing bench press all through college and in my early twenties.  Guys love the chest pump and of course nothing impresses a girl more than broad shoulders, a big chest and beefy arms, right?

Then as I began gaining years of experience as a therapist and started my personal training career, I began to realize a common scenario in men lifting weights regularly.  They had horrible posture, weak posterior chain strength and sore shoulders.  The common thread was this:

• Bench press and loads of chest exercises 2-3x/week and maybe some occasional back exercises thrown in once per week. 

This repetitive bench pressing, dips and flies created a HUGE imbalance.  Keep in mind for every chest exercise you do, you should balance it with a back exercise.  Some believe the ratio of back to chest exercises should be 3:2, while others suggest 2:1.  Suffice it to say I just believe we need less pressing and flies and more back exercises in general.

The poor weak rotator cuff stands up tall in the teens, twenties and early thirties, but it eventually starts to break down over time.  Aside from modifying range of motion, load and changing arm angles (all things I preach), you must work hard to reverse the effects of gravity by doing more upper/lower back training to prevent the caveman syndrome.

Your long term shoulder health depends on it.  I have rehabbed hundreds of shoulders going through rotator cuff and labral repair that are no doubt in some way related to lifting abuse.  Take my word for it when I tell you backing off the load, volume and frequency of bench pressing will add years of life to your shoulders and prevent you from living on anti-inflammatory medication to make it through the day.  I am not anti-bench per se, but I do believe once per week is more than enough for most of us.

Today, I have included a link to a recent column I wrote for PFP Magazine on one such posterior chain exercise to work the upper back and cuff.  Click here to read the column.

In addition, I added a video of the exercise below.  This is easy to do and will immediately improve shoulder health.  Consider adding it to your gym routine at least 2x/week on upper body days.

In closing today, I want to wish all of my friends, family, subscribers and followers a Happy Holiday Season!

Wow, it has been a while since I posted.  After battling what may have been H1N1 for nearly 2 weeks I am back at it.  I just returned from the Sports Physical Therapy Section Meeting in Las Vegas held last weekend.  All the brightest minds in the industry were there covering the latest research with an emphasis on knees and shoulders this year.

I must say I came away most impressed with Dr. Scott Dye.  He is an orthopedic surgeon at the University of San Francisco, CA.  He spoke on several topics but continued to highlight this concept of respecting the “envelope of function” in regard to activity and healing.  It really resonated with me as it sounded a lot like my concept of threshold training.

He believes we have a set envelope of function, if you will, that predetermines how much stress our body will absorb before breaking down.  There is the natural envelope and then an area he termed “supra physiologic load.”  Once we break this barrier of supra physiologic load, then mechanical tissue failure ensues.

He preached using bone scans as a diagnostic tool for measuring whether your body was really at tissue homeostasis as opposed to still being inflamed.  His assertion is that often we push people back to full activity too soon based upon subjective reports of no pain and clinical tests as opposed to measuring the joint itself with a scan to see if it is still reactive.

He raised a few eyebrows when he suggested that he does not let athletes return to play after ACL reconstruction until somewhere near 18 months.  While that may seem crazy, he had some interesting research he has done to show how his post-op patients do not get early arthritis at follow-up as far out as 15 years after surgery. 

In essence, he explained that we as practitioners must progress rehab and training in a very sequential and client specific way based upon this envelope of function theory.  While I am not sure I bought  his rehab time lines lock, stock and barrel, I do believe he is right on track with this envelope of function idea.

I have been saying for years that pain is not a good sign during training or rehab.  My critics have often said you can push through some pain with frozen shoulder, rotator cuff pain and the likes with training in order to move forward.  I have always countered that your body has a threshold to activity.  The only surefire way to progress without re-injury is to adequately gage and understand the threshold level, while adding stress to the system only as able while staying within the threshold.

How do I measure the threshold?  I have included my basic definition below:

With a proper training threshold, the athlete or client learns how to grade and evaluate the stress on his/her body during every practice/training session, while gaining an understanding of the exact threshold itself.  The threshold (activity tolerance level) should increase or progress with subsequent training, and the use of pain or soreness in response ot said stress should be the guiding factor in adding more load or volume.

Key parameters to track include:

• Pain at rest or before activity
• Pain during activity
• Pain after activity
• Length of time for pain (if present) to resolve or return to baseline

Teaching athletes and clients to track and understand this concept is critical to long term health.  First, you must get them to honestly report their symptoms.  Then, you must earn their trust by reassuring them your goal is to return them to full activity as soon as possible but as safely as possible.  Finally, you must implement the system and relate it to the exercises for them to understand how to measure their body’s response.

As I work with elite level athletes and everyday folks struggling with SLAP tears, rotator cuff impingement and knee arthritis to name a few, I become more convinced that accurately gaging their threshold or envelope of function is the key component when it comes to successful exercise program design and progression.

I am often asked when is it safe to go back to play after an injury.  In most cases, I am dealing with lower body or back injuries with my athletes, so for the purposes of this post, I will address a lower body functional return to play paradigm.

The tricky part about this question is that no two injuries are created equal.  Sure, I will be the first to acknowledge that I have general approaches to certain injuries and have a sense of how long it should take most of the time.  But, over the past 13 years I have seen enough irregularity and differences to say that everyone heals and recovers differently.

For example, I have had athletes with a simple grade 1 ankle sprain not go back to sport for 6 weeks, whereas those with much more severe grade 2 or even grade 3 sprains go back in much less time.  Why?  There may be several reasons including compliance, body structure, previous medical history, fitness, pain tolerance, and the quality of the rehab to name a few.

In the end, rehab professionals and strength coaches must have sound knowledge of pathophysiology, tissue healing, and program design that ensures maximal progression with optimal tissue loading.  Messing up the stress gradient (too little or too much) will slow the return to play process.  Below are some major milestones my athletes must clear in order before we even get to what I term “functional rehab” or preparatory movement prior to controlled practice:

1. Full active range of motion
2. Normal strength on muscle testing
3. Normal walking gait
4. Symmetrical squat and lunge patterns
5. Single leg squat (back, hip or knee injury) and/or calf raise (ankle injury) within normal limits compared to uninvolved side
6. Single leg hops in place x 10 equal to uninvolved side with no pain or instability
7. Normal running gait on treadmill x 5′ without pain or instability
8. Lateral gait cycle within normal limits (shuffle, carioca and cross stepping)
9. Planned and predictive controlled agility without pain or instability
10. Low level plyometrics in 3 planes without pain or instability

After moving through this fundamental progression (may take days or weeks), the athlete may then begin to perform more demanding neuromuscular work.  This would involve more rotational work, full intensity sprints an cutting, and gradually the transition to reactive agility and speed drills.  Once the athlete completes this process, he or she is ready for controlled practice.

This is an area where I see student athletes get in trouble. They get “cleared” so to speak by the MD and go back to practice.  Cleared to a coach means full go, right?  The athlete should ease back into practice even after a carefully prescribed rehab plan like the one I just laid out.  However, too often, I see athletes rushed back to full practice too soon.  In the case of soft tissue and stress reaction injuries, this often sends them back to the training room or sideline much sooner than the coach or athlete would like.

What is the answer?  Controlled practice progressions with the idea of first increasing volume (total minutes) prior to restoring maximal intensity.  Athletes know what is hard and what hurts.  We just need to communicate with them.  Allow them to do the easier drills and fill up time with those prior to ramping up the intensity for the entire practice.

Let’s take soccer as an example.  Dribbling, passing and light shooting are lower level drills.  In contrast, set pieces and small sided games are much more demanding.  Athletes and coaches must use discretion when returning form play to avoid re-aggravating an injury.  Measuring pain before, during and for 24 hours afterward is crucial in determining how the body is absorbing the force and responding to the training stress. 

If soreness is lingering for more than 24 hours, this is a red flag that the volume and/or intensity is too much.  I educate all my parents, coaches and athletes to follow this simple 24 hour rule.  I have found if you do, you end up with predictable results in terms of recovery and return to play.  So, if you have suffered an injury, be sure to consider moving through a set functional progression and be sure to used a controlled return to play approach to ensure you make a full recovery.  Have questions?  Leave a comment or shoot me an email.

According to research, more than 70% of people in the US will experience at least one episode of low back pain (LBP) in their life.  What is known about LBP and jogging?  Keep in mind running is an extension activity in the spine.  It also involves obvious repetitive compression/loading with ground impact.

A recent study in the Journal of Athletic Training (Sept./Oct. 2009) looked at the impact of lumbar paraspinal muscle fatigue and postural adjustments seen in running.  Poor lumbar extension endurance has been linked to increased risk for developing LBP.  In this study, researches looked at 25 recreationally active participants with a history of recurrent episodes of LBP and 25 healthy controls.

The testing process included:

1. 5 minute warm-up on the treadmill
2. 60 seconds of treadmill jogging at self selected pace
3. 1 set of fatiguing isometric lumbar extension exercise
4. Another 60 second treadmill jog at the same speed

For your reference, the fatiguing lumbar exercise consisted of repeated cycles of 10 second, gravity resisted isometric contractions followed by a 10 second rest on a lumber hyper extension chair.  So, what did the results show?

In a nutshell, those with a history of recurrent LBP showed much less postural adjustment with the muscle fatigue compared to their healthy counterparts.  The healthy subjects tended to exhibit a more forward trunk lean (1.1 degrees or less lumbar lordosis) and increase lateral bend during jogging gait.

On the flip side, those with recurrent LBP, they tended to stay more upright (0.2 degrees of additional lean on average).  The authors feel this may indicate a coping mechanism due to core instability and a way to effectively stabilize the spine.    Increased trunk lean would increase forces on the spine and intervertebral disc.  The lack of change in the population with LBP may help explain excessive fatigue in the muscles that support the spine, pelvis and hips.

So what does this mean for those who have LBP?  The postural change, or rather lack thereof, may be an Aha moment in regard to the need for improved core training for runners and athletes.  It should also indicate that long term running or athletic competitions may increase the risk for more frequent LBP or a greater back injury. 

There are three big takeaway messages here:

1. Include low back extension endurance training in your workouts
2. Integrate appropriate core exercises (planks, side planks, 3 dimensional exercise) to improve strength and stability of the hips, pelvis and spine
3. Get professional evaluation and training from a knowledgeable fitness pro if you have LBP
