Simplifying Exercise Prescription in Rehab

1/18/2018

0 Comments

 
While manual therapy and education may play a crucial role in injury rehabilitation, injuries and pain respond the best in the long-term to progressive loading through exercise.  In fact, exercise is said to be "the closest thing to a miracle cure" (1), and is widely accepted as the means through which you can attain complete recovery.

Prescribing exercise can be intimidating for some therapists, so I wanted to provide some facts and guidelines that may help make this easier!

Fitting the Diagnosis to the Injury

Attaining an accurate diagnosis CAN be difficult, but is often the first stage to developing a treatment plan, including exercise. 

1. Do we know the actual pathology/diagnosis?
An over-reliance on imaging and unreliable ‘special’ tests may mean that the true pathology (AKA reason for the client’s pain) may not fully be understood. 
A) Imaging typically looks at the injury site at a specific moment in time. To develop a true understanding of the pathology, this information must be examined along with the patient's subjective history and movement patterns. A common example in knee pain would be that an x-ray finding of moderate osteoarthritis of the patella is an additional finding, when the true reason for the patient's knee pain is trigger points in the quadriceps caused by suboptimal movement control.
B) Many Special Tests are not that special.  A special test should look to confirm suspicions of a specific diagnosis - they should not be used initially when developing a diagnosis.  We know that many special tests lack sensitivity and specificity, and as a result are not helpful in confirming the diagnosis (even with a proper history and objective exam). Nicklaus Biederwolf, a physiotherapist and researcher, has this to say about special tests specific to the shoulder: "A great lack of consistency with regard to how, when, and what special tests to use in clinical examination for shoulder differential diagnosis is evident" (2).
C) Different health care practitioners may develop different diagnoses that fit the information gathered during their assessment, and their bias.  It is important to do a comprehensive assessment (including the client's previous medical history, mechanism of injury, pattern of pain, global movement patterns, and a specific joint/tissue/nervous system/vascular assessment).

2. Without imaging, we depend on clinical patterns to develop an accurate diagnosis, however similar pathologies may behave differently in the clinical setting. For example a partial thickness supraspinatus tear (one of the shoulder's rotator cuff muscles) may behave differently in one client versus other clients - and this may be for a wide variety of reasons:
A) Anatomical variations: The acromion (a protrusion on our shoulder blade, under which the supraspinatus tendon glides) come in all shapes and sizes. The same applies to the rest of our bones, and muscles/tendons in our body - we are not as symmetrical and standardized as you may think!
B) Regional Interdependence: Canadian Physiotherapists are known as 'The Movement Specialists' (3), so keep connecting the dots to determine how one area of the body may be affecting another!  The thoracic spine, neck, scapula and all of its connecting muscles and ligaments alter the dynamic control and posture of the shoulder, which ultimately impact the supraspinatus tendon.
C) Variations in nociception (sensing pain): Fewer pain nerve endings near the injury site, previous injury to nerve or blood supply at the area, or differences in central nervous system perception of pain on a global level will affect how a patient feels potentially harmful stimuli.
D) Multiple injuries: A mechanism of injury that may tear the supraspinatus may also injure other tissues in the area.  For example, there could also be an injury of the labrum, chondral surface of the humerus, biceps tendon, pec major, or subacromial bursa.  It is nearly impossible to identify/distinguish all of these pathologies in the clinic without imaging... BUT does it really matter? Read on!

What To Do.. in a World of Unknowns?

It can all get quite confusing..
The items above paint a muddled picture: It can be quite difficult to come up with the correct diagnosis due to many(!!!) factors. Luckily, despite this fact, there are a few things we can do that will promote successful recovery. 

1. It may be more important to focus on movement deficits first.
Our bodies are exceptional at healing themselves.  In fact, the best athletes in the world are the ones that recover the quickest (from training, games, or injuries). Most of the time, the injured tissue will heal on their own, but will leave us with tight muscles and poor movement patterns as a result of compensation. This means that pursuing imaging and specialist appointments may just end up being a waste of  time, health care dollars, and stress.  To start, the patient shoulder obtain a couple of opinions (physician and physiotherapist) to determine whether medical testing may be needed.  Following these opinions, it is usually best to focus on improving flexibility and movement control.

2. Zoom out; Broaden your perspective!
Often we warn patients against performing certain exercises, based on the fact that they have a certain pathology (e.g. with an acute partial tear of the supraspinatus tendon, stay away from dips or deep bench press).  Take a step back and look at global movement patterns - are there any other restrictions / dysfunctions that you could work on first? In our case example: Do you need to work on thoracic mobility, activating scapular upward rotators, releasing scapular downward rotators, activating deep neck flexors, releasing posterior rotator cuff, releasing adhesions at the interface of pec major / supraspinatus / long head of biceps? Maybe a further step back would even suggest asymmetries in lower body, lower back, or neck strength/mobility.

3. Prescribing the exercise.
Suggesting that the patient does a specific exercise is not enough.  Ensure that the correct exercise is performed correctly; Spend time on coaching form and don’t expect that your client knows how to do the exercise properly.  Lastly, discuss the importance of correct exercise:
    1. Volume
    2. Intensity
    3. Rest
    4. Tempo
By changing these four variables, we can ultimately train the tissue work for its intended purpose and improve
A) Muscular endurance
B) Muscular power
C) Muscular reactivity (plyometrics)
D) Tendon loading capacity

4. Test, and Re-Test
If you've taught the exercises well, allow adequate time for a beneficial result to occur, and re-test the client's functional deficits.

5. Lastly, a client’s most effective exercises may change overtime due to movement quality, tissue quality, perceived effort/challenge, ability to recover quickly, or the applicability to sport and life specific challenges.  Follow up a few weeks or months down the road to provide the best possible care to your client.

Preventing Injuries in the Mountain Athlete

3/15/2016

0 Comments

 
The Great Outdoors.  It is there for you to enjoy, to push your limits, and develop fortitude.  For some people, going outdoors can be synonymous with developing injuries, but there are steps you can take to mitigate future injuries from taking place.

The Right Fitness Level

Greater fitness leads to a better understanding of your limits, as well as the ability to achieve greater feats. A physical assessment by a good therapist or strength and conditioning coach can help you sort through the thousands of exercises out there to know which ones are relevant to your needs.

      - Slow, gradual increases in exercise and specific training are necessary (months and/or years).  Our bodies adapt well to gradual stresses, but if too much load is placed on it at once, expect failure and injuries.  It takes great dedication to yield great results. Most outdoor athletes peak in their 30s and 40s as they build cardiovascular endurance,  muscular endurance, and a resistance to injury.
      - Outdoor athletes often suffer overuse / over-training.  It is important to consider whether you have proper body mechanics during training and outdoor pursuits.  Have knowledgeable therapists, coaches and other athletes watch your form and provide suggestions. It is also important to include adequate cross-training, regular body maintenance (physiotherapy, massage, rolling), proper nutrition, and adequate rest.
      - As a general rule there are certain joints which must be stable (strong ligamentous and muscular support around the joint, which prevents excess joint motion) and others which must have good mobility (the joint is built to be very flexible, however the muscular support around the joint must be able to control this increased range).  As pertaining to lower body exercise, the core must be stable, hips must be mobile, knees must be stable, and the ankles must be mobile (Cook, Burton & Kiesel, 2010).


Try adding the following 20-minute routine into your regular workouts, three days a week.  It is a small corrective exercise program built to help the user become more aware of hip / knee / ankle positioning during single leg stance.  It is not meant to replace regular strength training.  Rather, it should enforce the principles of joint alignment, feeling posterior chain engagement and will allow good transfer to outdoor pursuits. 
 
A) Dynamic stretching. Perform dynamic stretching prior to exercise for 30 seconds per muscle group. A few lower body ideas include front/back and side-to-side leg swings, quick quadriceps stretches, quick piriformis/glute stretches, and hopping.
 
B) Airplane. At first you may need to hold onto something for balance, but eventually you should be able to progress to no hands.  Goal = 10 reps per side.

C) Step-ups. Face a mirror and line up the hips and knees on the working leg to be approximately 90 degrees.  Ensure that during the exercise, your knee tracks straight (not allowing it to collapse inwards or outwards).   Lean forward, try to feel your glutes and hamstring fire on the upper leg then push through the heel on the working leg as you step up (this will help you to activate the posterior chain). Goal = 10 reps per side, with 2 times the expected weight of your backpack and gear.


D) Single leg star balance. Reach as far in each of the four directions as possible, while bending the stance leg at the hip and knee during the reaching phase (this leg should remain straight in line from the hip to the foot).  Goal = 10 reps for each leg.  1 rep = a full cycle of the four directions.
 
Side note: Work to create symmetry in this test, as evidence suggests that a difference of more than 4 cm between left and right legs in ‘the forward reach’ component can help predict whether an athlete is at risk of injuring the leg (Smith, Chimera & Warren, 2014).  Tip: Place masking tape on the ground and mark the distance in centimeters.


E) Piriformis rolling and pigeon stretch.  1 minute rolling, 1 minute stretch per side.

F) Lateral Quadriceps rolling and stretch.  1 minute rolling (focus on the outside of the leg), 1 minute stretch per side.


Other Important Considerations

Start With The Right Intel
- Create specific training goals: How many days/hours, what gear do I need to use, am I familiar with the terrain?
- Become efficient and effective in your skill-set by learning the best decision making skills and techniques via free resources (friends, books, videos), and progressing to courses or hiring a guide.
 


The Right Gear
- Hiking poles take up to 25% of stress off your knees during descent (Schwameder, et al., 1999) help your legs save energy, and improve your balance on technical terrain.
- Boots that fit well can prevent crushed toes, and rolled ankles.
- Bring microspikes, mountaineering gear and/or avalanche gear if you expect snowy conditions.

7 Exercises Unfit For Your Workout

10/15/2014

2 Comments

 
When it comes to exercising, there are a lot of choices to be made; How often do I work out? Which body parts should I exercise? How much cardio, core, stretching, etc.. etc.. should I do? How many sets/reps/minutes? The list goes on and on… I’m about to make the exercise selection part of your workout a bit easier.  The following list describes 7 exercises that are best left OUT of your work out.  Read and enjoy! If you have any comments or questions feel free to leave them in the comment section or contact me personally!

1) Behind The Head Lat Pull Down

Picture
This is a great exercise to focus on mid and lower trap development as well as general lat development. You’ll see some of the strongest body builders in the gym doing it, and I only hope that they know it may be harming their neck and shoulders. Because of the head forward (neck protraction) position, you are likely to see muscles like the sternocleidomastoid (SCM), levator scapulae, and upper fibers of the trapezius (traps) tighten up.  These muscles are common sources of neck pain, reducing functional neck range of motion, as well as encouraging scapular downward rotation, which can create or further exacerbate shoulder dysfunctions.  Additionally, the position of extreme horizontal abduction and external rotation of the shoulder can cause a host of problems that are not limited to shoulder impingement syndrome, rotator cuff strains, labral irritation/tears, AC Joint compression, and ligamentous laxity.

2) Upright Row

Picture
The upright row focuses on strengthening the middle and posterior delts, rhomboids and upper traps.  It can certainly achieve this goal, however it comes with the risk of shoulder impingement.  I personally do not recommend this exercise to many people, but if I do it is always with the limitation of not bringing the elbows up above the shoulder level (as seen in the above picture).

3) Traditional Sit-ups, Crunches and Machines that Simulate Sit-ups

Stuart McGill would die and then roll over in his grave if I didn’t mention these exercises. Essentially, yes, these exercises can pack on some muscle and definition to the rectus abdominua, iliopsoas, rectus femoris, and the obliques… However to include these exercises in a regular exercise program is not worth the risk of injury.
Going back to basics for a moment- the core is essentially meant to create spinal stability.  Another way for me to say this is that the core musculature is meant to functionally operate as an anti-mover for the spine, contracting isometrically.  When you do a sit-up you are concentrically contracting the anterior core muscles. Additionally, Stu McGill’s research shows that each intervertebral disc in the lumbar spine has a finite number of spine bends (flexion) that it can tolerate. Due to the structure of the discs, repeated flexion (think rounding the back) is one of the worst motions for lumbar spine health. Crunches, sit-ups, and most abdominal machines in the gym FLEX the spine! So ..stop it!.. and stick to planks, and other exercises that keep the back in a neutral stable position.


4) Leg Press

Picture
I love the fact that you can really load up this machine and focus on leg strength, however there are three main flaws I see to using it:
1) The back and feet are planted and impacts the proper knee arthrokinematics (the movement of the joint surfaces) of the tibiofemoral joint to take place.  Typically as you straighten the knee, there is a conjunction external rotation of the tibia on the femur.  It is hypothesized that this machine will affect this conjunct movement.
2) The back is flexed and thus it experiences high levels of stress placed on the discs (especially at the lumbosacral junction).
3) The exercise does not have a lot of functional carry-over to sport or daily life – Have you ever known anyone to sit down and push 400 lbs of weight? 
My recommendation – Train functionally in an upright position!

5) Knee Extensions

Picture
This machine is great for building quad mass, but is not great for the:

1) Patellofemoral Joint Arthrokinematics:
(A) The way that the patella (knee cap) moves on the femoral condyles changes depending on whether you are performing an open or closed-chain exercise.  Powers et al. (2003) found that the patellofemoral joint kinematics during non-weight-bearing (open chain) exercises could be characterized as the patella moving on the femur, while the kinematics during weight-bearing (closed chain) exercises could be characterized as the femur rotating underneath the stable.  The latter of the two conditions provides the least amount of stress placed on the patellofemoral joint.
(B) There is often additional stress placed on the patellofemoral joint because the load that you must push with your shin is anterior to the knee joint, whereas during a squat, the load is often through the knee joint or posterior to the knee joint.

2) Tibiofemoral Joint Arthrokinematics:  For the same reason as explained in the leg press example above (#1), pushing your shin against the machine prevents some of the conjunct external rotation of the tibia on the femur, meaning that the joint mechanics may be dysfunctional and can lead to joint damage.


6) Back Extensions

Picture
This may be a good exercise to put on some erector spinal bulk, but over facilitation of this muscle group is already a common occurrence. Classically this facilitation occurs because of poor spinal stability via inhibited/weak deep core muscles (most significant = the multifidus muscles in this scenario). Performing this exercise may result in increased facilitation of the already facilitated erector spinae muscles.

7) Almost All Seated Exercises

Picture
Avoid almost all seated exercises, and especially ones that cause repeated lumbar rotation.  The worst ones to avoid include exercises like the seated torso rotation machine, or any machines that force you into lumbar flexion (as mentioned above in #3). Remember Stuart McGills advice from above? The lumbar spine should be able to move dynamically, but have static stability when loaded. What i mean by this is that when the spine is not under any stress, we should have full range of motion through flexion, extension, rotation and side flexion. However, when loaded, the core muscles should provide stability and should remain static. If the spine moves when it is under load, additional shear and compression forces will occur, resulting in wear-and-tear on the spine.

Lastly, when we must engage other muscle groups from a seated postion, we do not harness the stability and strength of the core.  As a result we likely are weaker in that exercise, and we could be placing our body at risk for injury.  Why? Because most sitting inhibits our ability to contract some of our core muscles (i.e. when sitting, the anterior abdominal cavity is compressed which inhibits the diaphragm from contracting), and some of our peri-core muscles (i.e. the glutes, hamstrings multifidi, erector spinae, etc. are lengthened and thus unable to contract as forcefully from the seated position).


Concluding Remarks

This is an interesting take on mobility that has helped me greatly: Always think about the body in terms of what should be mobile or stable. The following list will help to provide you with an understanding, and if applied correctly will help guide your training and any injury rehabilitation:   Ankle — Mobile Knee — Stable Hip — Mobile Lumbar Spine — Stable Thoracic Spine — Mobile Scapula — Stable Glenohumeral — Mobile Remember that each joint should have full ROM regardless of its main purpose. Read more about this approach from Gray Cook’s book, 'Movement',
