Common Questions About Shoulder Impingement Answered

Shoulder impingement is a common cause of shoulder pain, affecting many people, especially athletes and those with repetitive overhead movements. It happens when soft tissues like tendons and muscles are pinched in the shoulder joint, causing pain, weakness, and stiffness. The condition can often be treated without surgery, and 70-90% of cases improve with conservative care, such as physical therapy and lifestyle changes.

Key Points:

• Symptoms: Pain when lifting your arm, weakness, stiffness, and nighttime discomfort.
• Causes: Repetitive motions, aging, or a naturally narrow shoulder structure.
• Treatment Options: Ice, physical therapy, and in severe cases, surgery.
• Prevention Tips: Maintain good posture, strengthen shoulder muscles, and avoid repetitive overhead activities.

If you’re experiencing shoulder pain, early diagnosis and treatment are crucial to recovery. Read on to learn about symptoms, treatment options, and exercises to help you manage and prevent shoulder impingement.

Shoulder Impingement Causes and Treatment

Understanding Shoulder Impingement

Shoulder impingement happens when soft tissues get pinched between bones during movement. This occurs in the subacromial space - a small area (1.0–1.5 cm / 0.4–0.6 inches wide) located above the shoulder's ball-and-socket joint and under a bony projection called the acromion.

Think of it like a sliding door: when everything works properly, tissues move smoothly. But with impingement, they get trapped and cause pain.

Common Signs and Symptoms

Here are some typical signs of shoulder impingement:

• Sharp pain when lifting your arm overhead or reaching behind your back
• Weakness in the shoulder, especially when lifting
• Reduced range of motion due to pain and stiffness
• Pain at night, particularly when lying on the affected side
• Symptoms that worsen over time if left untreated

These issues often stem from anatomical differences and repetitive movements.

Common Causes

Shoulder impingement can be caused by a mix of physical structure and repetitive activities.

Anatomical Factors:

• A naturally narrow subacromial space
• Structural changes in the shoulder due to aging

Activity-Related Triggers:

• Athletes like swimmers, volleyball players, or handball players
• Professionals such as painters, carpenters, and hairdressers
• Manual labor involving frequent heavy lifting

Other risk factors include:

• Age (most common in people in their 60s)
• Jobs requiring frequent overhead movements
• Lifestyle choices like smoking or the use of fluoroquinolone antibiotics
• Previous shoulder injuries or ongoing instability

This condition is responsible for 44% to 65% of all shoulder complaints treated by healthcare providers.

Diagnosis and Treatment Methods

Getting the right diagnosis is key to effective treatment.

How Doctors Test for Impingement

Doctors use specific tests to check your shoulder's range of motion and pinpoint areas of tenderness:

• Neer Sign Test: The doctor moves your arm overhead to assess for discomfort.
• Hawkins-Kennedy Test: Your arm is raised to shoulder height and rotated inward.

Medical Imaging: X-rays can identify bone-related issues, while MRIs provide a closer look at soft tissue damage like tendon or ligament injuries.

"A pinching sensation in the shoulder when reaching the arm up may indicate impingement. However, the only way to know for sure is with a diagnosis, which requires a visit to a health care provider." - Brian Lee, MD, Orthopedic Surgeon

The combination of physical tests and imaging results helps doctors develop a treatment plan tailored to your needs.

Treatment Without Surgery

Most cases of shoulder impingement improve with non-surgical approaches.

Quick Pain Relief:

• Apply ice for 15 minutes, three times a day.
• Use heat for 15 minutes to improve blood flow.
• Take over-the-counter pain relievers like acetaminophen or ibuprofen.

Physical Therapy: A therapist will guide you through exercises designed to improve shoulder strength, mobility, posture, and scapular movement.

"Effective nonsurgical treatment for shoulder impingement focuses on relieving your pain and inflammation. This is followed by using various therapeutic methods to restore your shoulder joint motion. It also focuses on restoring the strength and coordination of your affected shoulder." - Saint Luke's Health System

When to Consider Surgery

If non-surgical treatments don’t provide enough relief, surgery may be the next step. These procedures are often done arthroscopically, using small incisions.

Common Surgical Options:

• Subacromial decompression to create more space for tendons.
• Bursectomy to remove inflamed tissue.
• Rotator cuff repair if necessary.

Post-surgery recovery includes:

• Wearing a sling for 1–2 weeks.
• Participating in a structured rehab program.
• A full recovery period ranging from 2–4 months, though it can take up to a year in some cases.

Surgery is typically considered only after other treatments haven’t worked.

Exercises and Prevention

Pain Relief Exercises

Certain exercises can help ease shoulder pain and improve movement. Here are a few that target pain relief:

Rotator Cuff Strengthening:

• External Rotation Exercise: Stand next to a resistance band anchored at elbow height. Keep your elbow close to your body, bent at 90 degrees. Rotate your forearm outward against the band's resistance. Do 10-15 repetitions.
• Side-Lying Exercise: Lie on your uninjured side with your affected arm on top. Hold a light weight with your elbow bent at 90 degrees. Slowly rotate your forearm toward the ceiling. Complete 10-15 repetitions.

Posture Improvement:

The Wall Angel exercise can help improve shoulder alignment:

• Stand with your back against a wall, ensuring your head, upper back, and hips stay in contact.
• Raise your arms to shoulder height and slide them up and down.
• Perform 5-10 repetitions.

Shoulder Blade Control:

The Scapular Push-up enhances shoulder mechanics:

• Start with your arms straight.
• Squeeze your shoulder blades together, then push them apart while maintaining control.
• Perform 10 repetitions.

Daily Prevention Steps

In addition to exercises, making small changes to your daily habits can protect your shoulders from further strain. Consider these tips:

Workspace Adjustments:

• Raise your computer screen to eye level to avoid slouching.
• Sit with your shoulders back and your neck straight.
• Take regular breaks to do shoulder blade squeezes.

Activity Modifications:

Activity Type	Prevention Strategy
Exercise	Start slow and gradually increase intensity.
Computer Work	Maintain good posture and take frequent breaks.
Overhead Tasks	Keep your elbows close to your sides when possible.
Recovery	Apply ice for 20 minutes after physical activity.

Training Tips:

• Warm up properly before any shoulder activity.
• Focus on balanced muscle development to avoid imbalances.
• Stay hydrated to support joint health.
• Allow enough recovery time between workouts.

Movements to Avoid Until Cleared by a Doctor:
