Anatomy & Body Systems
The shoulder comprises multiple joints working together:
GLENOHUMERAL JOINT:
- Ball-and-socket joint
- Greatest range of motion in body
- Static and dynamic stabilizers
ACROMIOCLAVICULAR (AC) JOINT:
- Connects clavicle to acromion
- Allows scapular rotation
SCAPULOTHORACIC JOINT:
- Scapula on chest wall
- Essential for shoulder function
Four muscles providing dynamic stability:
SUPRASPINATUS:
- Initiates arm abduction
- Most commonly impinged
- Located above spine of scapula
INFRASPINATUS:
- External rotation
- Located below spine of scapula
TERES MINOR:
- External rotation
- Smallest rotator cuff muscle
SUBSCAPULARIS:
- Internal rotation
- Largest rotator cuff muscle
ACROMION:
- Part of scapula
- Forms "roof" of shoulder
- Three types: flat, curved, hooked
SUBACROMIAL BURSA:
- Fluid-filled sac
- Reduces friction between tendons and bone
- Becomes inflamed in impingement
CORACOACROMIAL ARCH:
- Formed by acromion, coracoid, ligament
- Creates space through which tendons pass
During overhead movement:
- Greater tuberosity elevates toward acromion
- Soft tissues compress in subacromial space
- Normal: adequate space maintained
- Impingement: inadequate space, tissue compression
In Ayurveda, shoulder impingement relates to Vata Dosha aggravation:
- Vata : Governs movement and joints
- Vata-Asthi : Vata affecting bones and joints
- Ama : Metabolic toxins contributing to inflammation
Treatment focuses on pacifying Vata through warm therapies, anti-inflammatory herbs, and lifestyle modifications.
Types & Classifications
EXTERNAL (SUBACROMIAL) IMPINGEMENT:
- Most common type
- Soft tissues impinged beneath acromion
- Can be primary or secondary
INTERNAL IMPINGEMENT:
- Posterior impingement
- Common in overhead throwers
- Posterior supraspinatus and infraspinatus affected
PRIMARY IMPINGEMENT:
- Due to bony anatomy
- Curved or hooked acromion
- Osteophyte formation
- Less space available
SECONDARY IMPINGEMENT:
- Due to soft tissue dysfunction
- Rotator cuff weakness
- Scapular dyskinesia
- Muscle imbalances
- Instability
STAGE 1 (MILD):
- Pain only with strenuous overhead activity
- Minimal inflammation
- Often reversible
STAGE 2 (MODERATE):
- Pain with daily overhead activities
- More persistent inflammation
- May require formal treatment
STAGE 3 (SEVERE):
- Pain at rest
- Significant dysfunction
- May involve tendon degeneration or tearing

FAQ
Q: Can shoulder impingement heal on its own? A: Mild cases may improve with rest and activity modification. However, most cases require targeted treatment to address underlying causes and prevent recurrence.
Q: How long does it take to recover from shoulder impingement? A: Most patients improve within 8-12 weeks with appropriate treatment. Chronic cases may take longer. Early intervention leads to faster recovery.
Q: What is the best exercise for shoulder impingement? A: Pendulum exercises and rotator cuff strengthening are typically recommended. A physiotherapist can provide a tailored program based on your specific condition.
Q: Should I use heat or ice for shoulder impingement? A: Ice is generally recommended in the acute phase (first 72 hours) to reduce inflammation. Heat may help with chronic stiffness and muscle tension.
Q: Can I still exercise with shoulder impingement? A: You should modify activities to avoid pain. Low-impact exercises and specific shoulder exercises prescribed by a physiotherapist are generally safe and beneficial.
Q: Is surgery required for shoulder impingement? A: Most patients improve with conservative treatment. Surgery is reserved for severe cases that don't respond to 6-12 months of conservative care.
Q: What happens if shoulder impingement is left untreated? A: Untreated impingement can lead to chronic pain, progressive weakness, rotator cuff tears, and decreased function. Early treatment leads to better outcomes.
Q: Can shoulder impingement cause arm pain? A: Yes, pain can radiate from the shoulder down the upper arm. Numbness or tingling suggests more advanced involvement or nerve irritation.
Q: How can I prevent shoulder impingement from recurring? A: Maintain rotator cuff strength, practice good posture, use proper technique in sports and work, and address any muscle imbalances.
Q: Is shoulder impingement the same as a rotator cuff tear? A: No, they are related but different. Impingement is compression of tendons; a tear is an actual rupture. Impingement can lead to tears if untreated.
