Cervicobrachialgia: Causes, Symptoms, and Physiotherapy

Cervicobrachialgia is a painful condition characterized by pain originating from the cervical spine and radiating down the arm, sometimes reaching the hand and fingers. It is the cervical equivalent of sciatica: while in sciatica the pain radiates from the lumbar region to the leg along the sciatic nerve, in cervicobrachialgia the pain follows the course of the nerve roots of the brachial plexus, from the neck to the arm.

It is estimated that cervicobrachialgia affects about 5-10% of the adult population at least once in their lifetime, with a peak incidence between 40 and 60 years of age. It is more common in people who perform sedentary computer work or activities that require repetitive movements of the neck and upper limbs.

The good news is that in the vast majority of cases, cervicobrachialgia responds positively to conservative treatment with physiotherapy and specific exercises, without the need for surgical intervention.

Anatomy: the Brachial Plexus

To understand cervicobrachialgia, it is necessary to know the brachial plexus, the complex of nerves that originates from the cervical roots and innervates the arm. The involved nerve roots emerge from the cervical intervertebral foramina:

• C5: innervates the shoulder and deltoid, allows elbow flexion (biceps)
• C6: innervates the outer side of the arm and forearm up to the thumb and index finger
• C7: innervates the posterior part of the arm and forearm up to the middle finger, controls elbow (triceps) and wrist extension
• C8: innervates the inner side of the forearm up to the ring and little finger, controls hand grip
• T1: innervates the inner side of the arm, contributes to the intrinsic muscles of the hand

When one of these roots is compressed or irritated, the symptoms follow the corresponding anatomical distribution, allowing the experienced clinician to identify the level of compression even before instrumental examinations.

Causes of Cervicobrachialgia

Cervical Disc Herniation

The most frequent cause in young and middle-aged patients is cervical disc herniation. The nucleus pulposus protrudes from the annulus fibrosus and compresses the nerve root in the intervertebral foramen. The most affected levels are C5-C6 and C6-C7.

Cervical Spondyloarthrosis (Cervical Osteoarthritis)

In patients over 50-60 years old, the most common cause is cervical spondyloarthrosis: the formation of osteophytes (bone spurs) and the thickening of ligaments reduce the space of the intervertebral foramen, compressing the nerve root. Disc protrusions and osteophytes often coexist.

Foraminal Stenosis

The narrowing of the intervertebral foramen (the bony canal through which the nerve root passes) can result from osteoarthritis, disc protrusions, ligamentous thickening, or a combination of these factors. It is a frequent cause of chronic cervicobrachialgia, analogous to lumbar spinal stenosis.

Other Causes

• Cervical trauma: whiplash, falls
• Thoracic outlet syndrome: compression of the brachial plexus in its passage between the scalenes, first rib, and clavicle
• Tumors: rare, but to be considered in the differential diagnosis

Symptoms

Radiating Arm Pain

The cardinal symptom is pain that radiates from the neck to the arm, following the distribution of the compressed nerve root:

Associated Symptoms

• Cervicalgia: neck pain, often localized to the side of compression
• Paresthesias: tingling, numbness, “pins and needles” sensation along the arm
• Weakness: difficulty performing specific movements (grasping, lifting, wrist extension)
• Cervical stiffness: limited neck movements, particularly extension and rotation towards the painful side
• Night pain: worsening of pain during the night, with difficulty finding a comfortable position

Aggravating Factors

• Neck extension (looking upwards)
• Neck rotation and inclination towards the painful side (Spurling’s maneuver)
• Coughing or sneezing
• Prolonged sitting position

Differential Diagnosis

The brachial plexus is a network of nerves originating from cervical spinal roots (C5-T1) that innervates the arm, with each root supplying specific shoulder, arm, and hand regions. Cervicobrachialgia must be distinguished from other conditions that cause arm pain:

Carpal Tunnel Syndrome

Carpal tunnel syndrome causes tingling and pain in the hand (thumb, index, middle finger), but the pain does not originate from the neck and does not worsen with cervical movements. The two conditions can coexist (double crush syndrome).

Shoulder Pathologies

Supraspinatus tendinitis, adhesive capsulitis, and other shoulder pathologies cause pain localized to the shoulder and proximal arm, but without tingling in the fingers and without correlation with cervical movements.

Epicondylitis

Epicondylitis causes lateral elbow pain, but the pain location is localized and does not radiate from the cervical spine.

Instrumental Diagnosis

• Magnetic Resonance Imaging (MRI): imaging of choice to visualize herniation, protrusion, stenosis, and radicular compression
• Electromyography (EMG): evaluates nerve root involvement and distinguishes cervicobrachialgia from peripheral neuropathy (carpal tunnel)
• Cervical X-ray: shows osteophytes, reduced disc spaces, curve alterations

Treatment

Acute Phase (0-3 weeks)

• Medications: NSAIDs, muscle relaxants, corticosteroids in short cycles (prescribed by your doctor or physical therapist)
• Soft cervical collar: only for 3-5 days in cases of very intense pain
• Relative rest: avoid activities that worsen symptoms, but not absolute rest
• Posture: sleep supine with a cervical pillow, avoid sleeping on the painful side

Physiotherapy

Physiotherapy treatment is the cornerstone of conservative therapy:

• Cervical manual therapy: joint mobilizations of the cervical vertebrae, foraminal decompression
• Neurodynamics: nerve gliding techniques (neural flossing) to reduce tension on the compressed root — the cervical equivalent of neurodynamic techniques used in sciatica
• Cervical traction: manual or mechanical, to increase foraminal space
• Muscle strengthening: cervical stabilization and scapular strengthening
• Postural re-education: correction of postural alterations that contribute to compression

Infiltrations

In resistant cases, the specialist doctor may propose cervical epidural infiltrations with corticosteroids to reduce radicular inflammation.

Surgery

Surgical intervention is reserved for cases with:

• Progressive motor deficit
• Intractable pain after 6-12 weeks of conservative treatment
• Cervical myelopathy

Exercises for Cervicobrachialgia

Exercises must be performed under the guidance of your physical therapist, who will establish the progression based on the recovery phase and pain tolerance. Fundamental rule: no exercise should increase radiating arm pain.

Phase 1 — Decompression and Mobilization

Chin tuck

The fingers of one hand are placed on the chin as a guide. Lateral view showing the horizontal direction of movement and the straightening of the cervical curve.]

Lateral inclination towards the healthy side

[IMAGE: Person sitting with a straight back gently tilting their head towards the non-painful side (healthy side), bringing the ear towards the shoulder. The arm on the painful side hangs along the hip with the hand reaching towards the floor to accentuate decompression. Front view showing head tilt and arm position.]

Phase 2 — Neurodynamics

Median nerve neural gliding

[IMAGE: Person standing with the arm on the painful side slightly abducted 30 degrees from the body, elbow extended, palm facing the ceiling. The wrist slowly flexes (fingers towards the floor) while the head tilts towards the arm side. Then the wrist extends (fingers towards the ceiling) while the head tilts towards the opposite side. Two positions shown. Front view.]

Ulnar nerve neural gliding

[IMAGE: Person standing with the arm on the painful side along the hip. The elbow flexes, bringing the hand towards the shoulder, with the wrist in flexion and fingers forming a circle (like binoculars) around the eye. The movement alternates elbow flexion with hand to eye and elbow extension with arm along the hip. Two positions shown. Lateral view.]

Phase 3 — Strengthening and Stabilization

Cervical isometric strengthening

[IMAGE: Person sitting with a straight back pressing the palm of the hand against the forehead, resisting movement without moving the head. The neck muscles contract isometrically. Four directions shown: forehead (flexion), back of the head (extension), right temple (right lateral inclination), left temple (left lateral inclination). Front view.]

Scapular retraction with resistance band

[IMAGE: Person sitting or standing with a therapeutic resistance band stretched between both hands, arms extended forward at shoulder height. Hands pull the band towards the chest, elbows bend to the sides of the body, shoulder blades move closer to the spine. Posterior view showing scapular movement.]

Cervical stabilization in neutral position

[IMAGE: Person lying supine with a small rolled towel under the back of the neck supporting the cervical lordosis. Knees are bent with feet on the ground. The person gently presses the back of the neck against the towel while maintaining the chin tuck. Lateral view showing cervical alignment and pressure on the towel.]

Standing chin tuck with resistance

[IMAGE: Person standing with their back and the back of their head against the wall. A small folded towel is between the back of the head and the wall. The person presses the back of their head against the towel while maintaining the chin tuck, performing an isometric contraction of the deep cervical flexors. Lateral view showing alignment and direction of pressure.]

Recovery Times

The prognosis is generally good: over 80% of patients with cervicobrachialgia achieve significant improvement with conservative treatment within 3 months.

Prevention

• Correct posture: maintain the head in a neutral position, avoid cervical protraction
• Ergonomics: monitor at eye level, lumbar support, regular breaks
• Cervical and scapular strengthening: regular exercises for cervical spine stability
• Stretching: maintain flexibility of cervical and shoulder girdle muscles
• Adequate pillow: a cervical pillow that maintains spinal alignment
• Physical activity: swimming, pilates, yoga — activities that keep the cervical spine mobile and strong

Frequently Asked Questions (FAQ)

Frequently Asked Questions

What is the difference between cervicobrachialgia and cervicalgia?

Cervicalgia refers specifically to pain localized in the neck region. Cervicobrachialgia, however, involves pain originating from the cervical spine that extends beyond the neck, radiating down the arm, often reaching the hand and fingers. This distinction highlights the presence of nerve root involvement in cervicobrachialgia.

Can cervicobrachialgia cause tingling in the fingers?

Yes, cervicobrachialgia can indeed cause tingling sensations in the fingers. This symptom typically arises from the compression or irritation of nerve roots in the cervical spine, which supply sensation to the upper limb and digits. The specific fingers affected can provide clues about the involved nerve root.

How to distinguish cervicobrachialgia from carpal tunnel syndrome?

Distinguishing cervicobrachialgia from carpal tunnel syndrome involves identifying the pain’s origin and distribution. Cervicobrachialgia pain originates in the neck and radiates down the arm, whereas carpal tunnel syndrome typically causes pain, numbness, and tingling primarily in the hand and wrist. A thorough clinical evaluation by a healthcare professional is essential for accurate diagnosis.

How long does it take to recover from cervicobrachialgia?

Recovery times for cervicobrachialgia can vary significantly depending on the underlying cause, severity, and individual response to treatment. Most cases respond well to conservative management, with improvement often seen within several weeks to a few months. A physical therapist can provide a personalized prognosis and treatment plan.
