♨️ PAINFUL ARC SYNDROME♨️
Painful Arc Syndrome refers to shoulder pain that occurs within a specific arc of arm elevation, typically between 60° and 120° of abduction. Outside this range, movement is usually less painful or pain-free.
---
🎯 Common Causes:
1. Supraspinatus tendinopathy or partial tear
2. Subacromial bursitis
3. Shoulder impingement syndrome
4. Calcific tendinitis
5. Acromioclavicular (AC) joint pathology (pain > 160°)
---
📌 Clinical Features:
Pain during active shoulder abduction, especially between 60°–120°
No pain during passive abduction
Pain subsides after 120°
Often worse with overhead activities
May have night pain or difficulty sleeping on affected shoulder
---
🧪 Diagnosis:
Observation during shoulder abduction
Hawkins-Kennedy test, Neer’s impingement test
MRI or ultrasound may reveal rotator cuff or bursa involvement
---
🧠 Differential Diagnosis:
Rotator cuff tear
Frozen shoulder (adhesive capsulitis)
Labral tear
AC joint arthritis (if pain at >160° abduction)
---
💪 Physiotherapy Treatment:
✅ Acute Phase:
Rest and avoid painful arc movements
Ice therapy 🧊
Anti-inflammatory medications (if prescribed)
✅ Subacute to Chronic Phase:
Postural correction
Strengthening exercises for rotator cuff and scapular stabilizers
Stretching of tight shoulder muscles
Manual therapy techniques to reduce subacromial pressure
Therapeutic modalities (ultrasound, TENS, laser)
---
✳️ Electrotherapy:
TENS for pain
Ultrasound to reduce inflammation
IFT to stimulate blood flow
---
🎯 Exercise Examples:
Pendulum exercises
Wall crawls
Isometric rotator cuff strengthening
Scapular setting exercises
✅ Physio Masud
❗ Important Note:
If untreated, painful arc syndrome can progress to chronic rotator cuff tear or frozen shoulder.
