Sternohyoid muscle spasm refers to involuntary tightening or cramping of the sternohyoid muscle—a thin, strap-like muscle in the neck. This article explains the anatomy of the muscle, the possible causes and symptoms of its spasm, how it can be diagnosed and treated (both with and without medication), and preventive measures. We also include answers to common questions to help you better understand the condition.

Anatomy of the Sternohyoid Muscle

Understanding the structure and function of the sternohyoid muscle is essential for grasping why spasms occur and how they affect the body.

Structure and Location

• Location: The sternohyoid muscle is located in the anterior (front) part of the neck. It is one of the infrahyoid muscles, meaning it lies below the hyoid bone.

• Shape: It is a long, flat, strap-like muscle that runs vertically.

Origin and Insertion

• Origin: The muscle originates from the manubrium of the sternum (the upper part of the breastbone).

• Insertion: It attaches to the inferior border of the hyoid bone, a U-shaped bone in the neck that supports the tongue.

Blood Supply

• Primary Blood Vessels: The blood supply comes mainly from branches of the superior thyroid artery and sometimes contributions from the inferior thyroid artery.

Nerve Supply

• Nervous Control: The sternohyoid muscle is innervated by the ansa cervicalis, a loop of nerves derived from cervical spinal segments (usually C1–C3).

Key Functions

1. Depressing the Hyoid Bone: Helps lower the hyoid bone during swallowing.

2. Stabilizing the Larynx: Provides support to the voice box during speech and swallowing.

3. Aiding in Swallowing: Works with other muscles to move food through the throat.

4. Facilitating Breathing: Plays a minor role in the control of the upper airway.

5. Contributing to Neck Movement: Assists with subtle movements of the neck and throat.

6. Supporting Posture: Helps maintain the alignment of neck structures.

Types of Sternohyoid Muscle Spasm

While the concept of “types” of sternohyoid spasm is less defined than for some other conditions, spasms can be broadly categorized based on their underlying causes or patterns:

1. Primary (Idiopathic) Spasm: Occurs without a clear cause.

2. Secondary Spasm: Triggered by underlying conditions such as stress, injury, or neurological issues.

3. Acute Spasm: Sudden onset, often related to an immediate trigger (like muscle strain).

4. Chronic Spasm: Persists over a longer period and may be related to repetitive strain or chronic conditions.

5. Activity-Related Spasm: Occurs during or after activities that stress the neck muscles.

6. Postural Spasm: Linked to poor neck posture over time.

Causes of Sternohyoid Muscle Spasm

Muscle spasms in the sternohyoid can arise from various factors. Here are 20 potential causes:

1. Muscle Overuse: Prolonged or repetitive strain from speaking, singing, or heavy lifting.

2. Poor Posture: Sitting or standing with an improper neck alignment.

3. Stress: Physical and emotional stress can lead to muscle tension.

4. Fatigue: Overworked muscles may cramp.

5. Dehydration: Lack of fluids can disturb muscle function.

6. Electrolyte Imbalance: Low levels of potassium, calcium, or magnesium.

7. Injury: Trauma to the neck region from accidents or sports injuries.

8. Neck Strain: Sudden, awkward movements or lifting heavy objects.

9. Infection: Infections causing inflammation in the throat or neck.

10. Thyroid Disorders: Conditions such as hyperthyroidism can affect neck muscles.

11. Nerve Irritation: Irritation of the nerves (e.g., from cervical disc problems).

12. Cervical Spondylosis: Age-related wear and tear of the neck vertebrae.

13. Anxiety: Chronic anxiety can manifest as muscle tension.

14. Spinal Cord Issues: Problems affecting the cervical spine.

15. Myofascial Pain Syndrome: Trigger points in the muscle can cause spasms.

16. Medication Side Effects: Some drugs may contribute to muscle cramps.

17. Autoimmune Conditions: Disorders like rheumatoid arthritis.

18. Local Inflammation: Inflammatory conditions of the soft tissues.

19. Repetitive Microtrauma: Minor injuries from repeated motions.
