The shoulder mobility screen in the FMS often reveals side-to-side asymmetries.  It is more common to see hypermobility in female clientele, while their male counterparts exhibit more hypomobility.  Overhead athletes tend to demonstrate excessive horizontal external rotation and a relative loss of internal rotation on the dominant side.  This hypomobility can be detrimental to overhead athletes and increase risk for overuse injuries if it becomes excessive.

The following exercise is an effective way to improve shoulder mobility and optimize function.  One important point is to focus on form and move very deliberately through the motion.

Execution: Begin lying on the floor face up.  Bend the left knee up to 90 degrees and cross the right leg over top of the left interlocking them.  Roll to the left side and pin a folded towel or pad between the right knee and the floor.  Place the arms in 90 degrees of shoulder flexion with the right on top of the left in an outstretched position. Next, slowly sweep the right arm up overhead and around the body as you attempt to place the torso/back on the floor.  The finish position for the right arm will be reaching the right hand and arm up behind the back.

Exhale as you perform the sweeping motion and hold the end position for 2 seconds.  Reverse direction and return to the start position.  Perform 5-10 repetitions on each side.

Application: Limited shoulder mobility is a common finding, especially among male clientele with tightness in the pecs, lats and posterior shoulder.  Asymmetry with respect to mobility is common with greater difficulty found trying to reach the dominant arm up behind the back on the FMS shoulder mobility screen.  This exercise will help improve thoracic spine motion and shoulder mobility.  The focus should be on strict form and proper stabilization to avoid unwanted motion.  Pinning the pad (or towel roll) to the floor will help ensure better stabilization.

If hypomibility is an issue and clients score a 1, foam rolling the pec minor/major, latissimus dorsi and the posterior rotator cuff musculature prior to performing the exercise will be helpful.  Stability training can be added in later once the soft tissue mobility restrictions and movement pattern is improving.

One of the most difficult problems to treat in the clinic is chronic pain related to tendinopathy.  More specifically, the Achilles tendon, patella tendon and elbow extensors often present challenges for doctors and clinicians alike when it comes to effectively reducing or resolving pain.  Over time, people develop chronic inflammation or even little tears in the muscles running up to the lateral epicondyle.

There have been many studies done looking at PRP over the past 5-10 years.  The debate continues, however, with respect to its efficacy in terms of results, especially given the fact that patients must currently pay out of pocket for the procedure.  I have written two earlier posts on PRP that you may be interested in reading as a back drop for this one:

2011 – An Update on Platelet Rich Plasma

2011 – Platelet Rich Plasma and Rotator Cuff Repairs

Currently, my approach to treating these injuries involves an approach focused on soft tissue mobilization via instrument assisted soft tissue mobilization, stretching, strengthening and a trial of iontophoresis in most cases.  We also offer dry needling at our facility and this has been effective in reducing pain.  I will talk more about this point later as it relates to the prospective multi-center trial summarized by Mishra et al. in the February 2014 edition of the American Journal of Sports Medicine.

Before I get to the study, I thought it would be pertinent to provide some straightforward information on PRP as it is a question that comes up with patients on a regular basis.  Essentially, the process is as follows:

1. Collect 30-60 ml of blood form the patient’s arm

2. Blood is then placed in a centrifuge.  The centrifuge spins and separates the platelets from the rest of the blood.

3.  A syringe is then used to extract 3-6ml of the platelet-rich plasma

4. The concentrated platelets are then injected into the elbow (or site being treated)

The thought behind PRP is to increase the growth factors up to 8x, which promotes temporary relief and stops inflammation. The question is how successful and cost effective is this process?  Consider that opting for surgery will run between $10,000 and $12,000 figuring in costs for the surgeon, hospital/surgery center, anaesthesiologist, etc.  PRP injections will cost upwards of $1000, so one would think that would be a favorable option for insurers if surgery could be averted.

What about cortisone injections?  They are widely used as a survey of 400 members of the American Academy or Orthopedic Surgeons found that 93% had administered a corticosteroid injection for lateral epicondylar tendinopathy.  According to Bisset et al (Br  Med J 2006) and Lindhovius et al (J Hand Surg Am 2008) cortisone injections do provide short term pain improvements but also result in a high rate of symptom recurrence.  There are other potentially harmful side effects from injections including: reduced collagen synthesis, depletion of human stem cells, depigmentation, and enhancement of fatty and cartilage like tissue changes that can lead to tendon ruptures.

So, the big question is whether or not tendon needling with PRP is an effective treatment option for chronic tennis elbow suffers. Mishra and his colleagues set out to examine this with a double blind, prospective, multi-center randomized controlled trial of 230 patients.  In the study, the patients were teated at 12 different facilities over 5 years.  All patients had at least 3 months of pain/symptoms and failed conservative treatment.

In the past, I wrote a post about Crossfit and shoulder pain based on a 38 y/o male client of mine.  Click here to read that post. In my prior entry, I discussed differential diagnosis of rotator cuff and labral pathology, as well as my treatment approach for that client.

If you follow my blog, twitter feed or webinars, you know I treat a lot of Crossfit athletes.  Recently, I worked with a 25 y/o female suffering from marked shoulder pain that was keeping her out of the gym.

Below are the key findings from her intake on 8/30/13:

• Onset of left shoulder pain on 8/8 related to snatches
• Right hand dominant
• Intermittent pain if sleeping on her left side
• Full AROM
• Mild weakness with supraspinatus and external rotation on left
• Positive impingement signs
• Positive O’Brien’s test (labral test)
• Positive sulcus sign bilaterally (indicates multi-directional instability or MDI)

Sulcus sign

Treatment intervention

1. Rhythmic stabilization and PNF exercises
2. Rotator cuff and scapular strengthening
3. Closed chain stabilization training
4. Game Ready (cryotherapy)
5. Home program issued at visit #1

I saw the patient once per week and she did her home program for 4 weeks.  At week 4, we gradually began allowing her to do some modified gym workouts but still no snatches or full overhead work.  She was pain free at this time and all impingement/labral signs had resolved.  At this point she returned to some wall ball drills (limited height) but still no snatches.

The client’s final visit was on 10/2/13.  Her Quick Dash percentage of perceived shoulder dysfunction was now 0%.  She was symptom free, but more importantly she had a great understanding of how to modify her lifts, loads and volume based on her multi-directional instability.  She was now aware of how her instability impacts her shoulder in “at risk” positions and in the face of fatigue.  This brings me to the primary reason for this second post related to Crossfit and shoulder pain.

In my initial post, I focused on overuse and shoulder inflammation as a result of poor mobility, muscle imbalances and a lack of physical preparedness to do high intensity exercise like Crossfit.  On the other end of the spectrum lies the unstable shoulder.

Hypermobility and/or shoulder instability is a major problem for those doing Crossfit in light of the following:

1. Many lifts and exercises put the shoulder in “at risk” positions
2. Poor glenohumeral joint stability places more stress on the rotator cuff and long head of the biceps
3. With the AMRAP approach and train to failure nature of the WOD, fatigue is a given and this means the stabilizing muscles that matter most will often fail leading to a much higher injury risk

Key Takeaways

• My client had secondary rotator cuff and bicipital irritation related to primary instability
• Rest and a combined stabilization and cuff/scapular strengthening exercise program was effective in resolving her symptoms within 30 days
• High load/high volume overhead lifts and those that place the shoulder at end range pose a higher injury risk for those with MDI or anterior instability
• Shoulder stability work trumps mobility work in those with shoulder instability – this often runs counter to traditional approaches that tend emphasize better mobility (one program does not fit all)

Closing thoughts

We must keep in mind that the shoulder is inherently unstable in order to allow us the freedom of movement necessary to perform the various tasks and exercise.  With that said, repetitive movements and lifts can create micro and/or frank shoulder instability over time.  Those with a history of shoulder subluxation/dislocation/instability are a high risk group to begin with. Adding high loads to failure places the shoulder in a fatigue and compromising state.  As a coach, competitor or health professional, we must remember that even the best intentions and coaching can fail us if the risk of a lift outweighs the reward.

As I have said before, anyone who decides to do Crossfit MUST get a proper assessment prior to starting to reduce injury risk. Ideally, this assessment would begin with a full FMS to help uncover any mobility or stability issues and asymmetry.  Keep in mind research reveals that females will almost always score a 3 on shoulder mobility and many may be hypermobile. Conversely, they tend to score lower (1 in many cases) on the trunk stability push-up.  Any pain with screening would necessitate a referral to a PT or MD for further evaluation.

Trainers cannot be asked or expected to catch multi-directional shoulder instability.  However, they can and should be aware of relative risk, anatomical tendencies and red flags that may predispose clients to injury.  For those wanting to be the best in the business, I would suggest developing a system for assessing clients and partnering with allied health professionals like me to incorporate best practices in their business.  Perhaps most importantly, trainers and coaches must be willing to adapt, limit, or eliminate exercise that does not fit the needs and abilities of the clientele.

The random nature of the WOD makes it difficult for unassuming clients to judge how best to fit in the Crossfit model if they have a dysfunction or injury concern.  My goal is always to empower people with knowledge about their body and sound advice for optimal training.  For those intent upon getting back to Crossfit after injury, I work hard to normalize their function and offer tweaks and modifications to prevent re-injury.  Prehab is a must for this population.  But in the end, some shoulders will simply not be able to handle the rigors and intensity of Crossfit.
