The Week in Research Review, etc 7-29-18

Last week was the 1st of my research review that summarized my social media posts from the previous week. It seemed to be well received so I figured I’d continue it. My goal is to help summarize some of the research that I found interesting and package it nicely for my readers.

Each photo contains a link back to a social media feed where you can see the conversation that ensued and maybe chime in…or just be a passive reader and see where the conversation went. You never know where the conversation may go on social media…so be ready! haha!


Socioeconomic Factors for Sports Specialization and Injury in Youth Athletes Jayanthi et al Sports Health Journal 2018.

This study looked at the effect of socioeconomic status (SES) on rates of sports specialization and injury among youth athletes.

They looked at injured athletes between the ages of 7 to 18 years that were recruited from 2 hospital-based sports medicine clinics. They compared these with uninjured athletes presenting for sports physicals at primary care clinics between 2010 and 2013.

They concluded that:
✅High-SES athletes reported more serious overuse injuries than low-SES athletes
✅More hours/wk playing organized sports
✅Higher ratio of weekly hours in organized sports to free play
✅Greater participation in individual sports

I applaud the authors for attempting to bring this very difficult collection of data into a formal research paper. I will say some of the statistics and standard deviations may not make the conclusions as powerful.

I do think this is a good paper to help educate our athletes on injury rates, especially in those that specialize in 1 sport.

From #Twitter’s @retlouping that perfectly sums up what I’ve observed recently on social media with many PT’s.

For some reason, pain science has overtaken most diagnosis and treatment conversations.

It’s as if you get bullied into talking pain science and ignoring our clinical judgment and diagnosis skills. I understand there’s a constant tug-of-war between the biomechanical PT’s and the pain science PTs.

But as usual, the answer usually lies somewhere in between and both groups are correct. The biomechanics of an injury are often important as well as the language we use to explain these tissue biomechanics.

To my fellow clinicians, especially the newer grads and #dptstudent, remember this little cartoon for every future encounter.

Yeah, speak to people in non-threatening tones (in my world it’s just being respectful) but trust me, they WANT to hear what could be going wrong or what may be causing their pain.

Don’t blow off their symptoms and don’t go into depth about pain science because they won’t understand.

Trust me, the clinicians that try to do that often end up losing their patients in the long run.

I hear these stories day after day of people coming to me because the last PT either only talks to them or made them ONLY do strength exercises and it didn’t help their pain.

The PT didn’t listen to them and was so blinded by their pain science background that they ignored the person sitting right in front of them. Remember, the person sitting there will tell you what is going on and what treatment will most help them feel/move better.


Influence of Body Position on Shoulder and Trunk Muscle Activation During Resisted Isometric Shoulder External Rotation Krause et al Sports Health 2018.

The purpose of this study was to examine ER torque and electromyographic (EMG) activation of shoulder and trunk muscles while performing resisted isometric shoulder ER in 3 positions:
✔️Standing
✔️Side-lying
✔️Side plank

Using surface EMG and a hand-held dynamometer, the researchers tried to determine EMG activity of the:
✔️infraspinatus
✔️Posterior Deltoids
✔️Mid traps
✔️Multifidi
✔️External/internal obliques (dominant side)
✔️External/internal obliques (non-dominant side)

EMG values for the infraspinatus were greatest in the side plank position. In general, EMG values for the trunk muscles were also greatest in the side plank position.

✅Their Conclusions: If the purpose of a rehabilitation program is to strengthen the rotator cuff, in particular, the infraspinatus, the side plank is preferred over standing or side lying. If the goal is to simultaneously strengthen both the rotator cuff and trunk muscles, the side plank position again is preferred.

Makes sense but good to see the research and have concrete evidence to back up what we think actually goes on.

Reliability of heel-height measurement for documenting knee extension deficits. Schlegel et al AJSM 2002

Prone heel-height difference of 1cm equates to 1.2 degree difference in knee extension ROM.

Do you use this method to assess knee ROM? I still measure knee extension ROM is supine but find this method helpful as well.

I know my friend and colleague @wilk_kevin has measured this way for many years. i originally saw his use this technique at @ChampionSportsM

I don’t want people to confuse this with prone hangs for knee extension ROM. I am not a fan of that method as I’ve stated in the past.

This is a method to assess knee extension differences, particularly after an ACL reconstruction. I have gone back to using this method for some people that have subtle ROM differences side-to-side.

The patella position (on the plinth or off) did not matter in the study and thigh girth did not appear to make a difference.

I would recommend stabilizing the pelvis to prevent excess ROM from occurring at that region and to better isolate the knee joint.

Have you tried this method? Tag a friend who may benefit from using this ROM method…thanks!


Evidence-Based Best-Practice Guidelines for Preventing #ACL Injuries in Young Female Athletes: A Systematic Review and Meta-analysis Petushek et al AJSM 2018.

Injury prevention neuromuscular training (NMT) programs reduce the risk for anterior cruciate ligament (ACL) injury.

Eighteen studies were included in the meta-analyses, with a total of 27,231 participants, 347 sustaining an ACL injury.

The overall mean training amount was 57 sessions totaling 18.17 hours (roughly 24 minutes per session, 2.5 times per week).

They concluded:

✔️Interventions targeting middle school or high school–aged athletes reduced injury risk to a greater degree than did interventions for college or professional-aged athletes.

✔️Continued exposure to neuromuscular training throughout the sport season seems to enhance prophylactic effects of NMT.

✔️NMT interventions were effective for female basketball, and handball athletes and interventions including various athletes were potentially effective (eg, soccer, basketball, and volleyball).

✔️ Interventions included some form of implementer training (eg, instructional workshop, video, or brochure) on proper program implementation.

✔️Programs including more landing stabilization and lower body strength exercises during each session were most effective.

🤔Programs including balance, core-strengthening, stretching, or agility exercises were no more effective than programs that did not incorporate these components.

✔️ Specifically, programs that included more landing stabilization exercises (eg, drop landings, jump/hop and holds), hamstring strength (eg, Nordic hamstring), lunges, and heel-calf raises reduced the risk for ACL injury to a greater degree than did programs without these exercises.

✅ Wow, lots of great information here. Please share this with a friend or colleague who may benefit from knowing this information.


Hope that helped to catch you up on my posts from this week.

The Week in Research Review, etc 7-22-18

The Week in Research Review, etc 7-22-18

I’m trying out this new concept of publishing my social media posts into a nice package for a weekly delivery to my subscribers.

  1. Knee Case Study
  2. Contralateral ACL Strengthening
  3. Shoulder Static Stabilizers
  4. Weighted Ball Research
  5. Glute Activation


This kid came to me the other day with L knee swelling after sliding headfirst into 2nd base during a baseball game.⠀

Continued to play in the game and even pitched the next day, all without pain or loss of motion.⠀

As you can see from the video, he has a bunch of fluid in his knee, medial ecchymosis (bruising) but full pain-free ROM.

Ligamentous tests appear negative and he has absolutely no pain or stiffness with anything.

I took this video to show what appears to be a bursal sac disruption from the impact of his knee into the ground as he was sliding.

The mechanism fits the presentation and clinical exam.

I advised him to monitor his swelling, wear a knee sleeve and continue his activities per his tolerance.

He is going to touch base with me next week to make sure the fluid is dissipating (and not worsening) and he remains asymptomatic.

What do you think? Am I missing anything? What’s your diagnosis? Tag a friend who may be interested in this case.

Cross-education improves quadriceps strength recovery after ACL reconstruction: a randomized controlled trial. Harput et al Knee Surg Sports Traumatol Arthrosc. 2018

This study looked at a group of ACL reconstructed patients that were divided into 3 groups.

All 3 groups performed the same standardized ACL rehab, but one group was the control group that performed the standardized rehab only.

The other 2 groups did either 3x per week extra concentric knee extensions on their uninjured leg for 2 months (beginning at 1-month post-op through 3-months post-op) or additional eccentric knee extensions on their uninjured leg 3x per week for 2 months between months 1-3 post-op.
💪🏼
They found that the quads strength for the concentric group was 28% greater compared to the control group. 💪🏼
The eccentric group was 31% greater when compared to the control group.

Conclusion: Concentric and eccentric quadriceps strengthening of healthy limbs in early phases of ACL rehabilitation improved post-surgical quadriceps strength recovery of the reconstructed limb.

Pretty crazy stuff and one more reason to work on bilateral strengthening with most of our patients, especially when they’re post-op ACL reconstruction.

Do you work on bilateral strengthening? if not, why? If you do, what other studies have you seen that show similar results?

This picture shows a simplified view of the static stabilizers of the shoulder joint. I highly recommend reading a classic paper by Wilk et al 1997 JOSPT that talks about this and cites a paper from Bowen et al Clin Sports Med 1991 @wilk_kevin

When one is picturing these stabilizers, the superior glenohumeral ligament (SGHL) is most taut when the shoulder is externally rotated at 0 degrees of abduction.

As we progress to 45 degrees of GH abduction, we stress the middle glenohumeral ligament (MGHL) as we externally rotate the humerus.

Finally, at 90 degrees of GH abduction, we stress the inferior glenohumeral ligament (IGHL) as we externally rotate. More specifically, the anterior band of the IGHL.

As we internally rotate at 90 degrees of abduction, we stress the posterior band of the IGHL.

These concepts have rehab implications and should be kept in mind when we’re rehabbing people after an injury or surgery.

For example, if someone has an anterior Bankart lesion (front labral repair), then we need to progress them slowly into external rotation, especially at 45 and 90 degrees of abduction.

Another example would be a rotator cuff repair, like the supraspinatus. We would want to progress them slowly at lower degrees of abduction 0-45 degrees but maybe we can progress them a bit quicker at 90 degrees of abduction.

Hope these concepts make sense because they are very important to understand for many patients with shoulder injuries.

Effect of a 6-Week Weighted Baseball Throwing Program on Pitch Velocity, Pitching Arm Biomechanics, Passive Range of Motion, and Injury Rates. Reinold et al Sports Health Jul-Aug 2018. @mikereinold

Our 1st of potentially 3 research articles looking at the effects of weighted balls on youth baseball pitchers.

High school baseball pitchers performed a 6-week weighted ball training program.

Players gradually ramped up over the 6 weeks to include kneeling, rocker, and run-and-gun throws with balls ranging from 2oz to 32 oz.

🤔After 6 weeks, the weighted ball group did increase velocity by 3.3%, 8% showed no change, and 12% demonstrated a decrease in pitch velocity. Also of note, 67% of the control group also showed an increase in pitch velocity.⠀

The weighted ball group had a 24% injury rate although half of the injuries occurred during the study, and the other half occurred the next season. There were no injuries observed in the control group during the study period or in the following season.

The weighted ball group showed almost a 5-degree increase in passive shoulder external rotation, also known biomechanically as the late cocking position or layback position.

There were no statistically significant differences between pre- and post-testing valgus stress or angular velocity in either group.

✅Our conclusion: Although weighted-ball training may increase pitch velocity, caution is warranted because of the notable increase in injuries and physical changes observed in this cohort.

Episode 705: “Hip Prep for Glute Activation”⠀
.⠀
Tag a friend looking for a glute🍑 killer!⠀
Hip prep is a series of 6 exercises I’ve adopted from my girlfriend @smenzz and her clinic @eliteorthosport. I use it with my patients to prime the glutes and lower body in general before getting into more dynamic and plyometric activities. I will make the statement right now: if done RIGHT, it’s an absolute glute killer & I promise you that you will feel your glutes!⠀
.⠀
I like these 6 exercises in particular for a variety of reasons.⠀
✅They challenge the glutes in all 3 planes of motion.⠀
✅They hit all types of muscle contractions: isometric, concentric, and eccentric⠀
✅They are performed upright in a functional position⠀
✅There is a variety of double leg, single leg, and split stance variations⠀
✅They train proper lower extremity alignment in a variety of hip and trunk flexed/neutral/extended positions⠀
.⠀
The 6 exercises are:⠀
1️⃣3 way clams: 5 per leg per position⠀
2️⃣Side steps: Alternating steps to the left and right starting with 1 step all the way to 5 steps⠀
3️⃣Monster Walks: 10 steps forward, 10 steps backwards⠀
4️⃣W’s: 10 steps to the left, 10 steps to the right⠀
5️⃣Squats: 10 squats⠀
6️⃣Single leg fire hydrants: 30s per side⠀
.⠀
💡Understand that you first need to teach these exercises in isolation first, before throwing someone all 6 at once⠀
.⠀
Have fun!⠀


Hope this helps you keep up to date and fulfill my goal of this website…simplify the literature and bring great content to you so you can apply it 1st thing Monday morning! Happy Reading! 👊🏼

The Evolution of a Physical Therapist

I’ve been a practicing Physical Therapist since 2003. I’ve observed a lot, talked to a bunch and read a lot. By all means, I am no expert! The evolution and growth of a physical therapist can take many roads.

I am always learning and listening but at times I do become complacent (that’s human nature). I’d be the 1st to admit that. I sometimes get stuck in my ways despite what others are saying in the literature or on social media.

I think that’s the great thing about social media…it keeps me listening. It has helped me to evolve and keep me on my game.

Ultimately, what has kept me on my game has been my desire to give my patients the best care that I can give them. I would expect the same from my own personal healthcare provider (I have a PCP, dermatologist, and a rheumatologist).

We have a responsibility to be the best for our patients. There are a lot of people chirping their opinions all over the place s I wanted to take this time to reflect on how I’ve seen many PT’s grow.

I’ve always wanted to write this post but I was inspired by my friend and co-owner of Champion Physical Therapy Mike Reinold when he posted this graphic on his Instagram feed.

I’d like to briefly chat about the evolution of a physical therapist through my eyes.

There seems to be a general development that occurs in the PT world- most are good but I’m beginning to see a side that is a bit disheartening. Maybe it’s a social media thing but I think we need to take a step back and re-evaluate for a second.

We’re always looking for a protocol to guide our patients. Here’s my attempt at the phases of a PT…Hope you enjoy (some of it is tongue-in-cheek so don’t get all crazy on me!)

The New Grad DPT student

This is the hungry, newly crowned physical therapist looking to break into the profession. Their eyes finally on the prize but probably scared to death (I hyperbolize). No more clinical instructors to guide you. No more reliance on someone else to lead the way. The plan of care is all yours!

Looking at your schedule for the next day or week, you may see that eval that worries you. Someone on the schedule with a diagnosis of “LBP” or a post-op ACL.

It was easier to treat these when your CI called the shots and you could observe, help and chime in with your thoughts and treatments. Accountability was minimal but the rewards seemed grandiose when the patient emerged with better function.

  • When is it safe to push an ACL?
  • How fast should one start strengthening after a rotator cuff repair?
  • When is it safe to start a throwing program after a Tommy John surgery?
  • What do you tell the patient when they come in with their 1st episode of acute low back pain and how do you treat it?

These are just a few of the challenges a new grad has to face.

Insurances are daunting. People can be daunting. You greatly influence the functional outcomes of that person sitting in front of you. Your words and actions matter but you don’t know that yet.

I often compare this stage to a new NFL quarterback who struggles to read defenses and rushes the ball when he throws…oftentimes to a defensive back waiting for an easy interception. He wasn’t anticipating that defense and got nervous. The game was moving too quickly and he can’t keep up with the schemes.

This is the new grad, a simplified version, but one that tries to do a lot but has minimal experiences and abilities to “read the defense.” The game is moving quickly and your decisions often come with little confidence.

But don’t worry, the game will slow down a bit.

2-5 years out and Feeling Confident

At this point, you’ve seen a bunch. You better understand the complexities of people, the medical system and how to kinda manipulate your way through. You realize that you can do it but your school studying was only a small prep for reality.

You’re motivated, finding your groove and beginning to get comfortable. There are still some questions but you don’t have to rely on the other PT’s in your group to help with progressions.

Pubmed has hopefully become your greatest ally, hopefully.

Although I do run into many that rely on Facebook and Twitter for their ‘research’. There’s always a post looking for advice on progressing a meniscus repair or return to a sport after an ACL.

I’ll often direct them to PubMed because just feeding people research is not helping them in the long run. They need to know where to find the information and learn how to interpret it.

The game is slowing down and your confidence is growing. Some even think they’re super-confident and try to ‘take on the world’. They are the ones out on social media leading the charge for change. A revolution of sorts…that their way is better than what has been done the past 5, 10, 20, 40 years!

They’re seeing their practice through rosy glasses with blinders. Blind to the fact that there are many before them who equally tried to champion a cause only to find out there’s more to it. The journey, although it seems triumphant and vigilant, falls short.

There will always be a new treatment technique, new modality a new system that is promising better outcomes. Your words, although seemingly loud, fall on so many deaf ears because the ship is going to steer itself. You’ve tried to lead the charge only to learn that the profession of PT is bigger than you.

You can only control what happens within your practice, or the few people that follow you on Instagram.  Although those ‘followers’ are often bots of some sort, pretending to like your content.

It’s a strange world out there, your words are seemingly wise, but there are so many out there shouting similar words that it gets drowned out. You think your experiences, although limited in the grand scheme of things, should guide your practice and the people that ‘follow’ you.

This, my friend, is where you’ve gone wrong. You have a ways to go. In fact, you’ll never get there. You’ll realize that each day presents a new challenge that doesn’t fall into a predefined mental algorithm.

When you have this revelation, then I think you’re ready to explore the next phase of your growth curve.

5+ years- beyond

The chart above calls you an expert but I’m not 100% a fan of this. No one in our field is truly an expert because there are challenges way above anything we could ever control.

Each personality that enters into our facilities presents with life stories that have shaped their pain, their expectations, and their outcomes.

But you know what, it’s at this stage that you realize that you are only a small piece of the puzzle. You can only help guide the process based on your plethora of experiences.

You’ve stayed on top of the literature and have altered how you practice. You no longer think that your way is the best but have dabbled in many other systems and taken a bit from all of them. Your way is NOT the best way.

You also have come to realize that there are always outliers out there. You know the ones that think the extreme positions are the best for all patients.

For example, there’s a huge social media push that says “manual therapy sucks”. No one should use manual therapy and you’re only wasting your time.

The flip side arguments say that there are many people that have a shifted inominate (whatever the hell that means) or a rib that is out of place. That therapist has been pounding on that pelvis or relocating that rib 1x per week for 52 weeks and has that patient convinced that they need more visits.

These are the outlier PT’s (I’m not speaking for other professions so don’t try to sucker me in) that are loud on social media but don’t necessarily represent the majority.

You see, the majority are trying to do it correctly (at least I think they are). The young PT that is 2-5 years out only sees those outliers as a challenge to his/her practice and is trying to yell at them. When in reality, you’re speaking to the minority, the group that barely exists.

You should be speaking to everyone else. The ones on social media that have taken a middle-of-the-road approach. They are doing their best, are on facebook looking for advice and busting their butts in the clinic.

They are limited by resources, time and updated knowledge. These are the people hungry to learn but are stuck somewhere in the 3 categories above.

These therapists are the ones you should be trying to chat with. You recognize that your vast experiences can help them.

It’s when you have this breakthrough that I think you’re ready to enter that last growth phase. You’re confident in your practice and willing to share. You speak to other groups, you publish clinical research, and you review research papers for journals.

To me, this is the utmost level and should be where most of the PT’s strive to get. Your knowledge continues to grow as you read. Each patient experience and interaction is another mental data point that sharpens your practice. These data points will blend in with your research readings and produce a so-called ‘expert’.

I invite you to challenge yourself by aligning with a clinician or group that produces clinical research, reviews journals and stays on top of the literature. Until then, don’t talk the talk unless you can walk the walk.

Some will think I’m being harsh, but I think you’ll have the realization, like I did back in the day, that our PT profession is bigger than us. Control what you can control and keep the ultimate goal in mind- THE PRIORITY IS TO GIVE THE BEST CARE FOR OUR PATIENTS, ALWAYS!

I’ve written about this before…about empowering the patient and keeping them in the driver’s seat. Check it out here.

I’d love to hear your comments. Please share with your friends, new grads and experienced PT’s. Social media has given many a voice but the loudest voices are not always the wisest voices!
