SportsMAP Advanced Upper Limb Rehab in Sport highlights
Highlights from SportsMAP Advanced Upper Limb Rehab in Sport, 30th Nov-1st Dec 2019
With a fair share of conferences covering injuries of the lower limb, the SportsMAP Advanced Upper Limb Rehab in Sport event provided a content rich weekend for those wishing to up skill in the management of shoulder, elbow and wrist injuries. Featuring some of the top clinicians in their field, the event did not fail to deliver, with the typical SportsMAP format of combining theory and practical sessions. This blog will present some of the key topics discussed throughout the weekend, and is by no means all the content covered over the 2 days!
Kicking the event off on Day 1 was Andrew McGough, Head Physiotherapist Diving Australia, with “The Sporting Shoulder”.
One of the recurring themes throughout the weekend was the importance of assessing the kinetic chain in athletes with injuries to the upper extremity: for a number of athletic actions (ie. throwing, hitting) the generation of force begins from the ground up. Neglecting to address issues further down the body may be the difference between failure and success in rehabilitating the athlete. Andrew used the case example of a 29 year old Strongman competitor with shoulder pain, who displayed poor trunk control.
“It must be realized that throwing is a whole body activity”
Andrew stressed the importance of both discussing with the athlete and then examining what they CAN and CAN’T do with their presenting complaint. “What can you do? Do that, What can’t you do? Modify that”
Examination of the throwing athlete
Physical examination of the athlete with shoulder pain should be comprehensive to address all potential contributions. This incorporates a full assessment of the kinetic chain. Andrew discussed some of the key tests that should form part of the examination:
When assessing flexibility, some tests that should be performed include:
Shoulder IR/ER range: total range 180 degrees
Lat dorsi/pec minor length
Thoracic extension/rotation range
Combined elevation test: should be able to get above ears
Knee to wall test
Hamstring/hip flexor/glut length
Active straight leg raise
Hip IR range (especially on lead leg)
Rubber duck test: get the athlete to close their eyes, squeeze a squeaky rubber duck and get them to touch it
Closed kinetic chain test
Upper limb Y balance test
Single leg squat (especially ability to load into trail leg)
Single arm wall push up
Side plank hold L vs R
Glut bridge single leg
Front plank hold
Int/ext rot in neutral: performed in standing, 3:2 ratio
Resisted ext and int rotation: can test at different ranges of external/internal rotation
Testing push and pulls at different positions and ranges
Following assessment, Andrew then discussed the possible intervention and rehab options that are available.
The Swimmers Shoulder
Session 2 saw Kylie Holt, Senior Sports Physio Swimming Australia, present on her area of expertise: the swimmer’s shoulder. Swimmers shoulder is a highly prevalent condition, occurring in 70% of swimmers and with no decrease in incidence in the last 36 years.
Kylie firstly clarified some of the potential contributors to the “swimmer’s shoulder”, with a number of often cited causes shown to be lacking in evidence, or with evidence to the contrary:
Absolute training volume: no studies linking absolute training volume
Limitation of ranges specific to swimming (internal rotation >40deg), external rotation (>93, <100): no difference in range with those with pain in Swimming Australia 70 swimmers Holt et al 2017. Not predictive of pain. Those with less humeral torsion were the higher level performers. Relatively antetorted bilaterally, not greatly different from the general population but different from throwing population.
Scapular dyskinesis: MacLaine 2018. Is important to assess. No necessarily strength related. Is dyskinesia secondary to pain?? Scapular upward rotation/ position is highly variable, don’t bother measuring just YES/NO
Strength imbalance: Boettcher et al 2019 in press: average ratio 3:2 Int/Ext, those with pain often maintain ratio but decrease strength in both. NOT predictive of pain. Using manual muscle testing to assess tendon health & monitoring.
Insufficient glenohumeral stability/laxity: vast majority of swimmers have laxity, but not classified as instability. They are just mobile. +ve sulcus sign in 82 of 84 (98%) shoulders examined. We want shoulder movement overhead, stop cueing down and back with shoulders.
Kylie then discussed her yet to be published research of the MRI imaging findings in 60 elite swimmers versus 22 aged matched controls.
Summary of the key findings from this study:
Tendinopathy is highly prevalent & major findings in swimmers
Anterior (subscap) and superior (supraspinatus) cuff affected equally: subscapularis (29.2% grade 3) and supraspinatus (30% grade 2) tendinopathic changes, with only 30% showing “normal” tendons in these regions
Biceps sheath effusion, labral pathology & lesser tubercle oedema not uncommon. 100% of all swimmers have swelling in the long head of biceps, leading to believe that this finding is “normal” in swimmers
AC joint pathology common
Subacromial bursa possibly less affected than thought: all subacromial bursa examined were within normal limits
Early phases of stroke most pain provoking
Single greatest predictor of tendinopathy in swimmers is years in squad training (especially for subscap tendinopathy).
Findings from this study are not consistent with an external impingement model: In the catch position the subscap is impinging with labrum, and the Supraspinatus is NOT in contact with the acromion. Subacromial external impingement probably less a factor than what previously thought, time for a new model?
"Swimmers Shoulder" Tendinopathy- Anterior superior internal impingement (ASII) and Posterior superior internal impingement (PSII)
Normal physiological internal contact in high degrees of elevation and internal rotation
Elite training volume potential to drive pathological response
Tendinopathy caused by mixed loading ie tensile, compressive & intra-substance shear
This ASII and PSII explains pathoanatomical findings i.e. subscapularis, biceps, supraspinatus & intra-articular changes
Things to keep in mind for management of the “Swimmers shoulder”:
Tendinosis is highly prevalent in swimmers
Changes in load therefore likely to be an issue (ACWR rather than absolute)
In many situations not a case of "here now- gone tomorrow"
Monitor and strengthen the muscle/tendon unit
Scapular upward rotation likely to be important
Avoid hyper elevated position where possible (i.e. kickboard kicking, chin-ups)
Are bursal injections as necessary as once thought?
Keeping with the SportMAP mix of theory and practical, it was time to get moving with a breakout into practical workshops.
First up Bruce Rawson, Head Physiotherapist Australian Baseball, took attendees through a throwing rehab workshop. Attendees were fortunate to have former Major League Baseball player, Brad Harman assist in this workshop, giving his unique experience of playing in the majors.
Again reiterating what was taught in the earlier theory session, attendees were reminded that throwing is:
Whole body activity
Therefore, when presented with an injury in the throwing athlete, important to address the 2 above factors.
Fundamentals are important in throwing, and one must not overlook the grip in throwers: if this is not right, then everything else can follow. The correct grip on a ball is 2 fingers on top thumb UNDERNEATH. A common error seen in throwers is the thumb coming up near the index finger, which tends to create a sideways movement when throwing. It is also important to have a gap between the ball and hands.
Other key aspects of throwing techniques examined in this workshop were:
Have the body is squared up side on to target
Step towards the target not off to the side.
Ensure that the arm does not winding back before lifting the front leg: they should be simultaneous to help with energy storage.
Follow through with the thumb down and across the body NOT just across the body
The second workshop with Andrew McGough saw attendees split into small groups and get creative with finding suitable rehabilitative exercises for case studies of 2 injured athletes. What was interesting to observe in this workshop was that all groups came up with different exercises, which demonstrates the multitude of rehabilitative options we have for the injured athlete.
The second day started with Bruce Rawson discussing rehabilitation of the shoulder and elbow in the throwing athlete. In late stage rehab & conditioning it’s important to consider both:
General conditioning AND
Throwing specific conditioning
Bruce then discussed some of the key exercises which should be part of a throwers rehabilitation program:
Power (again remember that throwing is from the ground up!):
Throwing creates 1-1.5x body weight distraction force through the shoulder, therefore the value of exercises like heavy carries and deadlifts can not be underestimated.
To address trunk rotation some potential exercises that can be used include:
Medicine ball throw: under arm, over arm focusing more on push
Tornado ball twist: standing or sitting on floor
Swinging ball on rope above head
To progress a throwing athlete through throwing progressions, simply increase resistance by increasing distance. Athletes need to “earn the right” to throw hard and often.
Focusing on the injured shoulder is not enough, you must assess the whole chain
Don’t forget the kinetic chain of developing force in the throwing athlete: Each body segment starts accelerating when the previous reaches its peak. Those injured will often have incorrect timing in linking these segments.
Ask the athlete when does their shoulder hurt?
Before release/cocking phase/acceleration: result = reduced velocity of throw. Check ER ROM
Release after the throw (velocity OK). Check IR ROM, strength (posterior cuff & capsule)
Bruce then discussed injuries to the elbow in the throwing athlete.
For suspicion of UCL injury at the elbow, it’s important to determine if the ligament is torn or not:tears don’t tend to heal often need surgery.
What protects the UCL? biceps and forearm flexors. Will often see tenderness in distal biceps and forearm as a sign of overload at the elbow.
When assessing the UCL, the standard tests don’t stress the UCL highly enough in throwers, so Bruce uses the “bounce test” in the cocking position. Look for pain reproduction in this position. Additionally, another test that can be used is getting them in the cocking position and then flexing and extending the elbow, again looking for pain reproduction.
This session then lead into another practical workshop with both Bruce and Andrew demonstrating some of the key exercises that can be used for the throwing athlete.
Next up Phil Cossens, Senior Sports Physio Rowing Australia, explored the unusual wrist & elbow presentations in the athlete.
Posterolateral instability of the elbow
Can be traumatic and acute or develop over a period of time
Posterior subluxation of the radial head
Rotation of ulna/olecranon in fossa
Severe cases can click
Mild cases associated with other conditions
Clinical assessment should include:
Table top test: (click here to view)
Palpate and feel for radial head moving posterior
Positive test is reproduction of their symptoms
Posterolateral rotatory instability test (pivot shift of elbow) (click here to view test)
Flex and extend the elbow, feel for movement or reproduction of symptoms.
Osteochondritis dissecans of the capitellum
Be aware of niggling soreness
This is a diagnosis that should not be missed
MRI is essential
Clicking & locking indicates a worse prognosis
Weight bearing (ie gymnastics) or throwing
Palpating capitellar WB surface: flex the elbow (to expose the weight bearing aspect of joint) and you can palpate it
May have small loss of flexion
Palpating for swelling in Elbow joint: elbow extended, palpate in olecranon fossa
Management: conservative management does work, but expect 6-12months
Hyperextension induced posterior impingement
Thickening of triceps tendon
Thickening of ulnar collateral ligament
