Cervical Radiculopathy

Spine

Overview

Cervical radiculopathy is a condition characterized by nerve root compression in the cervical spine, resulting in pain, weakness, and sensory disturbances radiating into the upper limb. The condition commonly arises from disc herniation, osteophyte formation, or foraminal stenosis and typically affects one nerve root. Clinical presentation varies depending on the affected nerve root level, with C5-C7 being most commonly involved.

Pathophysiology

Cervical radiculopathy develops when mechanical compression or inflammatory irritation of a cervical nerve root occurs within the intervertebral foramen or along its course. Common causes include posterolateral disc herniation causing direct compression, spondylotic osteophytes narrowing the foramen, facet joint hypertrophy, or ligamentous thickening. Inflammatory mediators from the intervertebral disc (phospholipase A2, TNF-alpha) contribute to nerve root irritation. The compressed nerve root experiences demyelination, impaired axonal transport, and local ischemia, leading to characteristic radicular pain that follows dermatomal and myotomal distributions. Secondary muscle guarding and postural dysfunction often perpetuate the condition.

Typical Presentation

Site

Unilateral upper limb pain following dermatomal distribution (commonly C5, C6, C7, or C8); pain may originate from the neck and shoulder region; less commonly bilateral

Quality

Sharp, burning, or lancinating pain with possible associated numbness, tingling, or 'pins and needles' sensation; may describe as electric or shooting quality

Intensity

Highly variable, ranging from mild to severe (VAS 2-9/10); often fluctuates throughout the day

Aggravating

Neck extension, ipsilateral rotation toward affected side, Spurling's maneuver, overhead activities, prolonged sitting with poor posture, coughing or straining, neck compression

Relieving

Neck flexion or contralateral rotation, arm elevation or support (hand behind head), rest, anti-inflammatory medications, ice or heat application

Associated

Neck stiffness and reduced cervical range of motion, weakness in myotomal distribution (C5: shoulder abduction/external rotation; C6: wrist extension/elbow flexion; C7: wrist flexion/elbow extension; C8: intrinsic hand muscles), reduced or absent reflexes corresponding to nerve root level, possible headache, scapular dysfunction, postural abnormalities including forward head posture

Orthopaedic Tests

Spurling Test (Cervical Compression Test)

Procedure

Patient seated or standing. Examiner extends the cervical spine, laterally flexes toward the affected side, and applies gentle axial compression through the head. A positive test can also be performed with the addition of rotation toward the affected side.

Positive Finding

Reproduction of radicular pain (sharp, shooting pain radiating into the arm/hand in the distribution of the involved nerve root)

Sensitivity / Specificity

50–60% / 95–99%

Tong et al., 2007, Spine; Hegedus et al., 2013, BJSM

Interpretation

High specificity suggests cervical radiculopathy when positive; low sensitivity means a negative test does not exclude the condition. Most useful as a rule-in test when positive.

Cervical Distraction Test

Procedure

Patient supine or seated. Examiner cradles the patient's head and neck, gently applying longitudinal traction (lifting upward) to decompress the cervical spine and intervertebral foramina.

Positive Finding

Reduction or abolition of radicular arm pain with traction; relief typically occurs within 5–10 seconds of applying traction

Sensitivity / Specificity

50–60% / 80–95%

Tong et al., 2007, Spine; Hegedus et al., 2013, BJSM

Interpretation

When positive, suggests mechanical nerve root compression (disc herniation or osteophyte). Negative test does not exclude radiculopathy. Useful as a complementary test to Spurling.

Upper Limb Tension Test (ULTT) / Brachial Plexus Provocation Test

Procedure

Patient supine. Examiner abducts the arm to 90°, externally rotates the shoulder, extends the elbow, and extends the wrist. The cervical spine is then extended and laterally flexed away from the tested side, or contralateral cervical flexion is applied.

Positive Finding

Reproduction of radicular symptoms (pain, tingling, or numbness in arm/hand) that is relieved when cervical spine is flexed toward the affected side (sensitizing maneuver)

Sensitivity / Specificity

60–70% / 50–60%

Wainner et al., 2003, JOSPT; Hegedus et al., 2013, BJSM

Interpretation

Helpful for differentiating nerve root involvement from other causes of upper limb pain. Lower specificity; should be used alongside other tests. May also implicate peripheral nerve involvement.

Neurodynamic Upper Limb Test Sequence (combining ULTT variants)

Procedure

Standardized sequence of upper limb tension tests performed in order (median, radial, ulnar nerve bias). Each test uses shoulder abduction, external rotation, elbow extension, wrist/finger extension, and cervical contralateral flexion.

Positive Finding

Reproduction of radicular symptoms with asymmetry between sides; relief with contralateral cervical flexion or scapular depression confirms neural bias

Sensitivity / Specificity

70–80% / 60–70%

Wainner et al., 2003, JOSPT; Rubinstein et al., 2015, Cochrane Database Syst Rev

Interpretation

More comprehensive than single ULTT. Better for identifying specific nerve root tension patterns. Sensitive but not highly specific; requires integration with other clinical findings and imaging.

Cervical Radicular Examination Cluster (combining Spurling, Distraction, and Ipsilateral Cervical Flexion)

Procedure

Perform Spurling test, cervical distraction test, and test reproduction/relief of symptoms with ipsilateral cervical lateral flexion. A positive cluster is typically defined as two or more of these maneuvers reproducing or relieving radicular pain.

Positive Finding

Two or more tests positive (Spurling reproduces pain, distraction relieves pain, or ipsilateral flexion relieves pain)

Sensitivity / Specificity

72–90% / 87–95%

Wainner et al., 2003, JOSPT; Cleland et al., 2007, Spine

Interpretation

Combined clinical cluster shows significantly improved diagnostic accuracy compared to individual tests. More reliable for ruling in cervical radiculopathy when multiple findings are consistent.

Nerve Root Palpation (C5–C8 Foramen Tenderness)

Procedure

Patient supine or seated. Examiner palpates the lateral cervical spine at the level of suspected nerve root compression (C5–C8 levels), applying gentle pressure to the foraminal region. Patient rotates head toward the affected side to further open the foramen.

Positive Finding

Reproduction of radicular pain, increased tenderness, or radiation of pain down the arm when palpating the affected foramen

Sensitivity / Specificity

See current literature / See current literature

Interpretation

Palpatory finding that may support clinical suspicion of foraminal stenosis or nerve root involvement; correlates with imaging findings in some cases. Limited evidence for diagnostic accuracy; best used as adjunct to other tests.

Osteopathic Techniques

Region

Cervical spine (ipsilateral to radiculopathy)

Technique

HVLA

Rationale

Cervical HVLA applied contralateral to symptoms can reduce foraminal stenosis and decompress the affected nerve root by increasing intervertebral foramen diameter. Evidence supports its efficacy in acute cervical radiculopathy with careful patient selection and contraindication screening. Immediate improvements in range of motion and pain may occur.

Region

Cervical spine (symptomatic levels)

Technique

MET

Rationale

Muscle energy techniques targeting cervical musculature reduce protective muscle guarding and normalize vertebral segmental mobility. MET is particularly effective for improving cervical rotation and flexion-extension asymmetries that contribute to foraminal compression. Safe and patient-controlled approach suitable for acute presentations.

Region

Upper cervical, cervicothoracic junction, and shoulder girdle

Technique

Soft Tissue

Rationale

Soft tissue techniques address secondary myofascial restrictions in the upper trapezius, levator scapulae, sternocleidomastoid, and cervical paraspinals that perpetuate postural dysfunction and nerve root irritation. Reduces muscle tension contributing to foraminal narrowing and improves neurovascular supply to compressed tissues.

Region

Intervertebral foramina and cervical nerve roots

Technique

Functional

Rationale

Functional osteopathic technique positions the spine in directions of ease, reducing mechanical stress on the compressed nerve root and allowing tissue healing. Particularly beneficial in acute presentations where direct mobilization is contraindicated; allows gentle restoration of mobility.

Region

Thoracic spine and thoracic outlet

Technique

HVLA

Rationale

Thoracic spine restrictions commonly contribute to cervical radiculopathy through mechanical and neurophysiological mechanisms. Addressing thoracic hypomobility relieves compensatory cervical loading and improves upper limb neurodynamics by reducing thoracic outlet syndrome components.

Region

Cranial and cervicothoracic fascia

Technique

Lymphatic

Rationale

Cervical lymphatic drainage and fascial release techniques reduce neurogenic inflammation around the compressed nerve root. Improves lymphatic clearance of inflammatory mediators and edema contributing to symptoms; supports parasympathetic nervous system engagement for pain modulation.

Add-On Approaches

Chinese Medicine

Traditional Chinese Medicine approaches often treat cervical radiculopathy as obstruction of Qi and Blood flow through cervical meridians (primarily Gall Bladder, Triple Burner, and Small Intestine channels). Acupuncture at local points (GV14, GV15, SI12) and distal points according to affected dermatome may reduce pain and neurogenic inflammation. Moxibustion over stagnant areas and herbal remedies addressing Qi stagnation and blood stasis (e.g., Du Huo Ji Sheng Tang) complement manual therapy.

Chiropractic

Chiropractic management typically involves cervical spine adjustments (often contralateral to symptoms) to reduce foraminal stenosis, combined with postural correction and ergonomic counseling. Diversified or Gonstead technique applied to cervical vertebrae aims to restore normal biomechanics. Cervical traction may be utilized to decompress nerve roots. Rehabilitation and lifestyle modification are emphasized.

Physiotherapy

Physiotherapy emphasizes active rehabilitation including postural education, cervical stabilization exercises targeting deep neck flexors and extensors, scapulothoracic control, and neural mobilization techniques (e.g., upper limb neurodynamic sequences). Progressive strengthening, range of motion restoration, and ergonomic modification form the foundation of long-term management. Manual therapy combined with exercise demonstrates superior outcomes.

Remedial Massage

Remedial massage addresses myofascial restrictions in the cervical, shoulder, and upper thoracic regions. Soft tissue release of upper trapezius, levator scapulae, and cervical paraspinals reduces protective guarding. Trigger point therapy targeting referral patterns to affected upper limb can provide symptomatic relief. Lymphatic drainage techniques support tissue healing by reducing localized inflammation.
