Today, we will discuss Supraspinatus, a crucial muscle that plays an essential role in shoulder joint stability and movement.
Have you ever felt discomfort or pain when lifting your arm? If so, dysfunction of the Supraspinatus could be the cause!
📌 What is the Supraspinatus? Where is it located?
The Supraspinatus originates from the supraspinous fossa of the scapula and attaches to the greater tubercle of the humerus. It is one of the four muscles that make up the Rotator Cuff, which plays a vital role in shoulder stability and movement.
✅ Anatomical Features of the Supraspinatus
(Source: Netter's Atlas of Human Anatomy, Gray's Anatomy)
- Location: Posterior surface of the scapula, within the supraspinous fossa
- Origin: Supraspinous fossa of the scapula
- Insertion: Greater tubercle of the humerus
- Innervation: Suprascapular nerve (C5–C6)
The Supraspinatus is essential for shoulder stability and movement.
📌 What is the function of the Supraspinatus? Why is it important?
The Supraspinatus plays a vital role in shoulder joint movement:
✅ Shoulder Abduction: Responsible for initiating the first 15 degrees of arm elevation away from the body
✅ Shoulder Joint Stability: Helps stabilize the shoulder joint and prevent dislocation

These functions make the Supraspinatus crucial in daily activities that involve lifting and reaching.
📌 What happens when the Supraspinatus is damaged or tight?
If the Supraspinatus becomes tight or injured, the following issues may arise:
❌ 1. Shoulder Pain and Restricted Movement
Tightness or injury in the Supraspinatus can cause pain in the upper shoulder and limit the ability to lift the arm.
❌ 2. Shoulder Instability
Weakness in the Supraspinatus can decrease shoulder joint stability, increasing the risk of dislocation.
❌ 3. Impingement Syndrome
Because the Supraspinatus passes underneath the Acromion, excessive friction or compression in this area can lead to shoulder impingement syndrome.

📌 How to Keep the Supraspinatus Healthy! Simple Stretching and Strengthening Techniques
To maintain Supraspinatus function, regular stretching and strengthening exercises are essential:
✔️ 1. Supraspinatus Stretching
🔹 Steps
1️⃣ Sit or stand comfortably.
2️⃣ Extend one arm in front of your chest and hold the elbow with the opposite hand.
3️⃣ Gently pull the extended arm toward the chest to stretch the back of the shoulder.
4️⃣ Hold for 20–30 seconds, then return to the original position.
👉 Repeat 2–3 times daily for best results.

✔️ 2. Supraspinatus Strengthening Exercise (Empty Can Exercise)
🔹 Steps
1️⃣ Hold a light dumbbell or water bottle in your hand with your arm positioned next to your body and your elbow bent at 90 degrees.
2️⃣ Move your arm 30 degrees forward from your torso.
3️⃣ Slowly lift your arm until it reaches shoulder height.
4️⃣ Gradually return to the starting position.
👉 Perform 10–15 repetitions for 3 sets.

📌 Conclusion: Keeping the Supraspinatus Healthy is Key to Shoulder Health!
The Supraspinatus is essential for shoulder stability and movement. If you experience pain or movement restrictions when lifting your arm, it is important to check the condition of this muscle.
✅ Maintain proper posture throughout the day
✅ Perform regular stretching and myofascial release techniques
✅ Seek professional consultation if persistent pain occurs
⚠️ However, not everyone with Supraspinatus dysfunction will experience problems. Individual differences in body structure, lifestyle habits, and muscular balance should be considered, and professional diagnosis may be necessary.
