Rotator cuff syndrome: causes, symptoms & treatment of the shoulder
What is the rotator cuff?
The rotator cuff is a group of four muscles and their tendons that stabilise and move your shoulder joint. They are:
- Supraspinatus
- Infraspinatus
- Teres minor
- Subscapularis
Together they make sure that the head of your humerus stays securely in the socket and that you can move your arm with control.
The shoulder is the most mobile joint in the body, but that is exactly what makes it prone to problems. The rotator cuff therefore plays a central role in the balance between stability and mobility.
What is rotator cuff syndrome?
Rotator cuff syndrome describes various problems in the area of this muscle-tendon structure, for example:
- Irritation or inflammation (tendinitis)
- Wear (tendinosis)
- Partial tears or complete tendon tears
These changes often arise in the so-called subacromial space, a narrow area under the shoulder roof where the tendons run. The supraspinatus is often especially affected.
Causes & risk factors
In most cases the problem does not arise suddenly, but over time through several factors:
Overload & repeated movements
- Overhead work (e.g. trades, nursing)
- Sports such as tennis, swimming or volleyball
Repeated movements can lead to small micro-injuries that add up over time.
Ageing
- From about the age of 40, the load capacity of the tendons decreases
- Poorer blood flow → less regeneration
Important: changes are common, even without pain.
Anatomical factors
- Narrow space under the shoulder roof
- Bone spurs or shape variants of the acromion
- Instability in the shoulder joint
Acute injuries
- Falling onto the arm
- Sudden pulling load
- → can lead to partial or complete tears
Muscular imbalances
- "Movement muscles" that are too strong (e.g. chest, shoulder)
- Stabilising muscles that are too weak
This leads to unfavourable loading in the shoulder joint.
Typical symptoms of rotator cuff syndrome
The symptoms often develop gradually:
- Pain when raising the arm (typically at 60–120°)
- Radiating into the upper arm
- Night pain (especially when lying on the shoulder)
- Loss of strength in the arm
- Restricted mobility
In everyday life, things like:
- Getting dressed
- Combing your hair
- Reaching overhead
become increasingly difficult.
The course: why early treatment is important
Without treatment, the symptoms can get worse:
- increasing pain
- restricted function
- possible tendon tears
Early therapy can influence the course clearly for the better and often avoid surgery.
What can you do yourself?
Acute: reduce pain
- Take the load off the shoulder (no overhead movements)
- Still: light movement in the pain-free range
- Cool for acute pain (15–20 minutes)
- Heat for chronic tension
Gentle mobilisation
Pendulum exercises:
Let your arm hang loosely and move it gently back and forth or in circles.
→ promotes blood flow & reduces stiffness
Adjust sleep & everyday life
- Don't sleep on the affected shoulder
- Support your arm when lying down
- Reduce overhead work
Exercises for rotator cuff syndrome
Targeted training is one of the most important building blocks of therapy.
Early phase (isometric)
- External rotation against a wall
- Internal rotation against a wall
- Press your arm lightly against resistance
- → hold for 5–10 seconds each, 10 repetitions
Build-up phase (with resistance)
- External rotation with a resistance band
- Internal rotation with a resistance band
- Lateral raise (light weight)
→ 2–3 sets of 10–15 repetitions
Whole-shoulder exercises (Y-T-W)
They train overall shoulder stability:
- Y position
- T position
- W position
→ especially effective for the rotator cuff and shoulder blade control
Mobility & stretching
Good mobility is crucial:
- Chest stretch (against a rounded back)
- Stretch for the back of the shoulder
- Shoulder circles
- Thoracic spine mobilisation
Goal: better biomechanics and less pressure on the tendons
Ergonomics & everyday tips
Small adjustments often make a big difference:
- Screen at eye level
- Elbows close to the body
- Regular breaks
- Avoiding overhead loading
- Carrying loads close to the body
Good posture takes an enormous load off your shoulder in the long term.
How can physiotherapy help?
Targeted physiotherapy is one of the most important building blocks for shoulder problems.
Goals of treatment

- Night pain
FAQ: frequently asked questions about the rotator cuff
What is rotator cuff syndrome?
A collective term for irritation, wear or tears of the shoulder tendons.
Can it heal on its own?
Mild symptoms can improve, but targeted training is usually decisive for a lasting solution.
Is pain during training normal?
Mild discomfort is okay, but severe pain should be avoided.
Do I always need surgery?
No. Many problems can be treated very well conservatively (without surgery).
How long does healing take?
Depending on severity, between a few weeks and several months.
