Cervical repetitive neck strain (CRNS) is a common condition caused by repeated overuse or awkward positioning of the neck. Over time, tiny injuries accumulate in muscles, ligaments, tendons, and joints of the cervical spine (neck), leading to pain, stiffness, weakness, and reduced range of motion. Understanding CRNS in plain, simple language can help you recognize early signs, seek timely treatment, and prevent long-term complications.
Anatomy of the Cervical Spine
Structure & Location
Vertebrae (C1–C7): Seven small bones stacking from the base of the skull to the top of the thoracic spine.
Intervertebral Discs: Cushion-like pads between vertebrae that absorb shock.
Facet Joints: Small joints at the back of each vertebra guiding motion.
Muscles & Ligaments: Support and move the head.
Nerves: Thirty-one pairs exit the spinal cord; eight cervical nerves control sensation and movement in the neck, shoulders, arms, and hands.
Origin & Insertion of Key Neck Muscles
Sternocleidomastoid
Origin: Sternum (breastbone) and clavicle (collarbone).
Insertion: Mastoid process (behind the ear).
Trapezius (upper fibers)
Origin: Occipital bone, nuchal ligament.
Insertion: Lateral third of clavicle, acromion of scapula.
Levator Scapulae
Origin: Transverse processes of C1–C4.
Insertion: Superior medial border of scapula.
Scalenes (anterior, middle, posterior)
Origin: Transverse processes of C2–C7.
Insertion: First and second ribs.
Splenius Capitis
Origin: Spinous processes of C7–T3.
Insertion: Mastoid process and occipital bone.
Semispinalis Capitis
Origin: Transverse processes of C4–T6.
Insertion: Occipital bone.
Blood Supply
Vertebral Arteries: Run through the transverse foramina of C1–C6, supply spinal cord and brainstem.
Ascending Cervical Artery: Supplies muscles and ligaments.
Deep Cervical Artery: Branches nourish posterior neck structures.
Nerve Supply
Cervical Nerve Roots (C1–C8): Exit above corresponding vertebrae (except C8 exits below C7).
Dorsal Rami: Innervate the muscles and skin of the back of the neck.
Ventral Rami: Form the brachial plexus (C5–T1) for arm control.
Functions of the Cervical Spine
Support: Holds head upright (approx. 4.5–5 kg).
Protection: Shields spinal cord and nerve roots.
Flexion: Bending head forward.
Extension: Bending head backward.
Lateral Flexion: Tilting head side to side.
Rotation: Turning head left and right.
Types of Cervical Repetitive Neck Strain
Postural Strain: From sustained poor posture (e.g., “text neck”).
Occupational Strain: Repetition at work (e.g., assembly-line tasks).
Sports-Related Strain: Repetitive movements in sports (e.g., swimming).
Load-Carrying Strain: Frequent heavy backpacks or headgear.
Whiplash-Type Strain: Repeated micro-movements after head trauma.
Computer-Vision Strain: Prolonged computer or mobile device use.
