Shoulder Injuries In Dancers

By: Texas, Grace, Sam & Megan

Our Main Curiosity

An exploration into typical dance related shoulder injuries. Using somatic theory to find appropriate ways of releasing tension whilst also finding strengthening exercises for shoulder dislocation.

Our Main Curiosity

LOWER EXTREMITY INJURIES ARE MORE COMMON!

The Shoulder

'If all the bones involved in the shoulder girdle were extended laterally , we wouldn't be able to walk through a door!'

(Olsen, 1998)

The Shoulder

Key concepts:

Mobility/stability

Force couples

•Upper/lower body connection

Key Anatomical Features

The bones of the shoulder complex include the:

• 2 scapulae

• 2 clavicles

• 1 sternum

• 2 humerus bones

Other Important Features:

  • Labrum
  • Rotator Cuff
  • Deltoid Minor and Deltoid Major
  • Biceps Tendon
  • (Haas, n.d.)

Key Joint Motions

Specific Movement

Glenohumeral Joint

(Where the head of the humerus meets glenoid cavity)

A ball and socket joint with a shallow cavity

There a THREE planes of movement

1) Sagittal 2) Frontal 3)Transverse

Capability of: Flexion, Extension, Abduction, Adduction & Internal and External Rotation

Scapulothoracic Joint

(Where the scapula meets the thoracic spine)

Not a true anatomical joint- considered an articulation

Slides freely over the back of the rib cage (scapula)

Capabiliy of: Elevation, Depression, Protraction,

Retraction & Upward and Downward Rotation

Strengthening

Strengthening exercises are key in the rehabilitation of a dislocated shoulder.

Strengthening

Some examples of strengthening exercises are:

  • Wall Presses
  • Stabilizer
  • Scapular Setting

Stabilizer

• Fill ¾ of a 1.5 l water bottle with water.

• Pick up the bottle with your right hand and stretch your arm straight out in front of you.

• Make sure your hand is at the height of your shoulder and your arm is straight. Now try to hold the bottle steady.

• Hold this position for 30 to 60 seconds, then switch sides and repeat the exercise. Do three sets per side.

Stabilizer

Scapular Setting

Scapular

Setting

• Lie on your stomach with your arms by your sides.

• Place a pillow under your forehead for comfort, if required.

• Gently draw your shoulder blades together and down your back as far as possible.

• Ease about halfway off from this position and hold for 10 seconds.

• Relax and repeat 10 times.

Common Injuries

In Dance

Rotator Cuff Tendonitis and Impingement:

-This injury can become common in dancers due to the overuse of raising the arms.

Shoulder Dislocation

-This injury occurs when the humerus is completely or partially out of the glenoid. When this is only partial, it is known as a subluxation.

Rotator Cuff Tear

-This injury occurs when the rotator cuff tendons are fully or

partially torn.

Types Of Injuries

What Injury We Are Looking At

Shoulder Dislocation

What Injury We Will Look At

Anterior and Posterior Dislocations

1) In BOTH types of dislocation there is usually a severe bone defecton on the humeral and glenoid side

2) Ususally only present with mild pain but significant loss of motion

3) CAN casue signifcant bone & cartilage deconstruction as well as scar formation in soft tissues

4) Lead to instability which causes repeated dislocations

Role of the Glenohumeral Joint in dislocation and sublaxtion

-Large range of motion but limited stability- shallow socket

-Reliance on capsule & ligament structures as well as the rotator cuff group (for stability)

Somatic Practices

In Brief...

Somatic Practice

Many somatic practices to help with shoulder tension, mending and release.

Can stretch from simple breathing exercises, floor work, own movement analysis and functional integration.

Each practice has a different approach to helping shoulders.

Functional integration is good for bringing awareness to anatomy of the shoulders & discovering how tight/loose they are.

Breathing exercises are very good for releasing tension.

Putting Theory Into Action

ADDRESSING OUR CURIOSITY...

Theory into

Practice

Using 2 methods as a way of building strength and bringing awareness to the shoulder girdle.

Exercise 1) Feldenkrais & Functional Integration

Exercise 2) Wall Press

Aware that releasing tension is not suitable when dealing with a dislocation, we still undertook the exercise based on the

fact dancers hold unnecessary tension.

It is not useful to push through muscle tension ,

it will only generate more tension

(Olsen, 1998)

Exercise 1:

Feldenkrais

Excercise

1

Feldenkrais. Including own awareness of movement and functional integration.

One person on their side on the floor, the other in full control of their shoulder joint.

The person in control of the shoulder joint will move the shoulder around, the person laying on the floor discovers how much mobility/ tension they have.

An addition to this is to feel around the person's shoulder blade, the person laying down can locate where that is too.

Exercise 2:

WALL PRESS

Excercise

2

An important part of treating instability and reoccurring dislocations is through retraining the scapula

ISOMETRIC SHOULDER EXERCISES ARE KEY TO RECOVERY

1) This particular exercise is a form of isometric flexion

2) Muscles are worked without moving the joint- static exercise

3) These muscles include the deltoid major and minor- an important adductor

4) Important in the prevention of sublaxtion and dislocation due to a high role of stabilizing the joint.

5) Avoidance of elevation subsequent to recent dislocation

6) Involves protraction and retraction which in favour

prevents scapular winging

Conclusion

Feldenkrais has helped in the past.

Our shoulders feel a lot less tense, we are a lot more aware of the positioning of our shoulders.

Wall presses are helpful in the rehabilitation of a dislocated shoulder and can help to build strength in the joint to prevent further injury.
