There are several things that contribute to shoulder impingement and rotator cuff pain.  Perhaps one of the biggest issues that impacts overhead athletes, Crossfit enthusiasts and the avid weight lifter is limited shoulder mobility.  Poor flexibility in the pecs, lats, posterior shoulder as well as limited thoracic spine extension and rotation all contribute to suboptimal movement.

Poor mobility can place the scapula in biomechanically flawed positions, increase glenohumeral internal rotation and restrict shoulder movement at end range creating compensatory movement and pain.  The video below is a snippet from my upcoming webinar on rotator cuff dysfunction and nonoperative treatment.

This webinar will be great for strength coaches, exercise enthusiasts, Crossfit athletes/coaches, athletic trainers and physical therapists.

So, I just returned from the Combined Sections Meeting for the APTA that was held in Indianapolis.  There was lots of great networking and presentations to be sure.   I attended sessions on ACL rehab/prevention, femoroacetabular impingement, elbow injuries in throwers, running gait analysis, and shoulder plyometric training with the legendary George Davies.  I thought I would give you my top 10 list of helpful nuggets I picked up over the weekend in no particular order of importance.

1. Performing upper body plyometrics has no effect on untrained subjects so don’t waste time putting it into the rehab program, where as it does benefit trained overhead athletes.  The one caveat is it also increases passive horizontal external rotation so keep this in mind when working with athletes who have shoulder instability.

2. A new study  coming out in 2015 in AJSM revealed no major differences in throwing kinematics between those following UCL reconstruction (Tommy John) and age-matched controls.  This is good news for those worried about pitching mechanics after the procedure.

3.  According to Dr. Reiman at Duke, the orthopedic hip exam does a better job of telling us they do not have a labral tear than it does telling us they do have an intra-articular problem.  The tests have poor specificity.  In fact, he goes on to say that the “special tests are not that special.”  That brought a chuckle from the crowd including me.  Bottom line – we are not really able to conclusively say “yes you have a labral tear based on my exam today.

4. Reiman also feels we must consider look for mechanical symptoms during the lowering portion of the Thomas test, while considering the fact that fat pad impingement may cause anterior hip pain as opposed to joint pain.  Again, things are not always as they appear in the “FAI” crowd so we need to take a great history, look at the classic tests and also see how squatting and loading affects the hip.

5. More experienced pitchers do not drop the glove side arm, but instead tend to move their body toward the glove to conserve angular momentum and overcome small moments of inertia.  Less experienced pitchers rotate their trunk sooner in pitching cycles whereas pitchers who threw at higher levels rotated later and produced less torque at the shoulder.  Consequently, many players with higher elbow valgus torque and distraction force at the shoulder rotate too early.

There seems to be consistent questions, debate and studies done with respect to stretching.  As the thought of more closely analyzing the quality of movement (FMS, Y-Balance testing, SFMA for example) moves to the forefront in the PT and fitness world, many search for the right mix of exercise to maximize mobility.

I count myself as a supporter and follower of the work of Gray Cook and Stuart McGill.  While I may not agree 100% with all of their ideas, I generally consider them to be brilliant minds and ahead of the curve.  I have been using the FMS in my practice for some time now and have also begun to incorporate Y-Balance testing as well (see pic below courtesy of the IJSPT)

The Y-Balance test may not have significant relevance to hip mobility as much as it does limb symmetry, but I included it here to illustrate my point in observing kinetic chain movement to help determine where the weak link or faulty movement pattern may be.  It gives us valuable information with respect to strength, balance and mobility.

With the revelation that FAI is more prevalent than we knew (click here for my post on FAI), I am always interested in hip mobility and how to increase movement in the hip joint.  Limitations in hip mobility can spell serious trouble for the lumbosacral region as well as the knee.

I currently use foam rolling, manual techniques, dynamic warm-up maneuvers, bodyweight single leg and hip/core disassociation exercises and static stretching to increase hip mobility.  However, I am often faced with the question of what works best?  Is less more?  How can I make the greatest change without adding extra work and unnecessary steps?

Well, Stuart McGill and Janice Moreside just published a study in the May 2012 Journal of Strength & Conditioning Research that sought to examine three different interventions and how they improve hip joint range of motion.  Previous work has been focused on the hip joint alone, and they wanted to see how other interventions impacted the mobility of the hip.  Click here for the abstract

Dysfunctional movement is common with shoulder pain and impingement.  One dysfunction you may encounter is a downwardly rotated scapula. If upward rotation is limited, a client will display excessive shoulder flexion above 90 degrees when the humerus is in maximal internal rotation.  Typically, a person will have minimal flexion beyond 90 degrees if the scapula is moving properly.

Upward rotation of the scapula is the result of a force couple between the upper and lower trap along with the serratus anterior.  If any of these muscles are weak, rotation can be limited and overpowered by the rhomboids and levator scapulae muscles (both downward rotators).  This pattern of muscle dominance is common.

Additionally, tightness in the rhomboids, levator scapulae, pec minor or latissimus can also restrict normal mobility.  It is probably safe to assume stretching of the chest and lats would be helpful, but it is critical to encourage the proper muscle firing patterns in the traps and serratus anterior as well.

Below is a video demonstrating wall slide shrugs.  The shrug should be done at or above 90 degrees.  You can perform reps at multiple angles or move to end range and perform a series there.

Application:  The exercise is designed to encourage upward rotation in a more functional manner as opposed to traditional shrugs with the arms at the side.  While I am not opposed to traditional shrugs with little or no weight for basic elevation, this position generally tends to activate the rhomboids and levator scapulae which is not desired given their natural dominance pattern.

The wall slide shrugs should not create any pain or discomfort.  However, they may feel awkward particularly if the client has a faulty muscle activation pattern.  As muscle tightness resolves and strength improves, clients should gain more mobility and optimal shoulder function.

I thought a fitting way to kick off the new year would be to share the top 10 things I learned or embraced that have most shpaed and impacted my training and rehab this past year.  In no particular order I will rattle these things off.  I hope at least one of these little pearls has a positive impact on your training and/or rehab as well.

1. Often times it appears necessary to perform a biceps tenodesis or tenotomy in active adults undergoing a SLAP repair to ensure more predictable pain relief.  I heard this at a sports medicine conference last May and I can tell you those patients having this done alongside their shoulder surgeries seem to recover quicker with less pain relief.  With that said, keep in mind that SLAP tears are difficult to define and operate on as surgeons still do not have great agreement across the board on defining the extent of injuries and how to deal with them (operative vs. non-operative).
2. Performance on the Functional Movement Screen (FMS) has little to no correlation with athletic performance.  I screened an NBA player and an NFL player this year who both failed the screen.  However, they obviously have mad athleticism and genetic ability.  Keep in mind the FMS is a valuable tool used to assess movement and expose injury risk patterns based on the 7 tests.
3. Soft tissue therapy is undervalued and misunderstood by most lay people.  Assessing tissue restrictions and educating our clients to perform self myofascial release techniques is essential if they want to compete and remain healthy day in and day out.  Specific problem areas I have increased my focus on this year have been the psoas, soleus and posterior rotator cuff/joint capsule.  Click here for my soleus blog post.
4. Core training is probably as much about not moving as it is about generating force with movement.  I read work from Stuart McGill and other smart people in the field, and the concepts of anti-rotation and anti-extension are sound concepts to explore and look more closely at.  Many times, performance in sport and life require us to resist movement and maintain position so strengthening the core to resist potentially harmful and stressful motions is and should be an important part of training and rehab programs.  Understanding how to facilitate and activate core musculature in the training to protect the spine and improve mobility/strength is key.  Click here for more on my core training.
5. Hip dissociation is an important element to train as the lack of it can impact function and performance in a negative way.  We assess it on the active SLR in FMS and I see the lack of it show up on clinical exams all the time.  Whether it is HS tightness, hip flexor weakness or simply poor neuromuscular control, clients who are unable to effectively dissociate the hips are more prone to injury and limited performance.
