“Doctor, I’ve recently been unable to raise my shoulder, and even putting on clothes has become difficult. Is this frozen shoulder?” This is one of the most common complaints heard in orthopedic or sports medicine clinics. Many people mistakenly think shoulder pain is just from a stiff neck or fatigue, but in reality, injury to the shoulder’s rotator cuff muscles is often the main cause of shoulder weakness and limited mobility.
What is the rotator cuff, and why is it so important?
The rotator cuff is composed of four muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles and their tendons work together as a stabilizing system, wrapping around and supporting the shoulder joint. They allow us to perform precise movements such as lifting, rotating, and raising the arm.
When these tendons experience chronic wear and tear, acute strain, or inflammation and tearing from repetitive use, the following symptoms may occur:
• Shoulder pain (especially when lifting the arm or putting on clothes)
• Night pain that affects sleep
• Limited range of motion, especially difficulty raising the arm overhead
• Shoulder weakness and tendency to drop objects
These symptoms are often mistaken for frozen shoulder or shoulder bursitis, which can delay proper treatment.
Who is at high risk?
• Middle-aged adults over 50: Tendons degenerate with age, increasing the risk of inflammation
• People with repetitive upper limb use: Teachers, laborers, homemakers
• Athletes and fitness enthusiasts: Those engaged in badminton, swimming, tennis, or strength training
• Individuals with poor posture: Chronic shoulder and neck tension, rounded shoulders, and slouching can also be triggers
What are the traditional treatment options?
Most people initially try rest, oral painkillers, hot compresses, or electrotherapy. However, if the pain persists for more than two weeks or begins to interfere with daily life, further evaluation is recommended, such as:
• Ultrasound examination: Real-time assessment of tendon tears or fluid buildup
• MRI (Magnetic Resonance Imaging): Evaluates the severity of damage and assists in determining whether surgery is needed
When diagnosed with rotator cuff inflammation or partial tears, conservative treatment is usually the first line of care, including:
• Physical therapy (deep heat therapy, electrotherapy)
• Anti-inflammatory injections
• Rehabilitation exercises and muscle strengthening
Advanced Treatment Options: Precision Diagnosis + Functional Reinforcement
At the Sports Medicine and Intelligent Recovery Center of the Tri-Service General Hospital, we integrate high-tech equipment with a multidisciplinary team to provide more comprehensive and precise treatment strategies for rotator cuff injuries:
• Ultrasound-Guided Injections
Using real-time imaging guidance, hyaluronic acid or prolotherapy agents are accurately injected into the injured area, minimizing the risk of leakage or accidental injection into nerves or blood vessels. This approach enhances both safety and effectiveness.
• Electromyography (EMG) Functional Analysis
Assesses the coordination of shoulder and surrounding muscle groups to identify hidden imbalances, thereby reducing the risk of recurrent inflammation.
• Movement Control and Therapeutic Exercise
Physical therapists design individualized programs focusing on scapular stability, core strengthening, stretching, and flexibility to lower the chance of reinjury.
• Luna EMG System and Shoulder Training Equipment-Assisted Rehabilitation
Combining the Luna EMG biofeedback system with lat pulldown shoulder training devices, this approach provides real-time muscle strength monitoring and stable resistance training. It helps enhance muscle control, improve movement coordination, increase rehabilitation precision, and support patients in gradually restoring shoulder function while reducing the risk of reinjury.
When Should Surgery Be Considered?
If the tendon is completely torn, conservative treatment fails after 3 to 6 months, or shoulder function is severely limited, the physician may recommend surgical repair. Nowadays, minimally invasive arthroscopic surgery is commonly performed, offering smaller incisions and faster recovery.
Active rehabilitation is essential within 6 to 12 weeks after surgery, or else there is a high risk of joint adhesions and limited mobility. At this stage, systematic and personalized training and follow-up provided by a sports medicine center are especially important.
Doctor’s Reminder: Early Diagnosis + Proper Training Are Key!
Rotator cuff injuries are not as obvious as fractures and are often overlooked or delayed. However, with early professional assessment and targeted rehabilitation training, most patients can avoid surgery and regain shoulder mobility and quality of life.
Shoulder stiffness and pain when lifting your arm are not minor issues. If you experience similar symptoms, we encourage you to visit a Sports Medicine Center for further evaluation. Let our expert team help identify the problem, design a personalized training plan, and restore healthy movement!
