Cervical Radiculopathy - Neck Flexion Causing "Tearing Sensation" from Neck to Fingers

Which Nerves Are Involved

"Spondylosis, osteophytes, and disk herniations at the C4-C5 level can affect the C5 root... Pathology at the C5-C6 level can affect the C6 root and cause sensory changes in the first two digits and/or lateral distal forearm... Lesions at the C6-C7 level compressing the C7 root cause sensory changes in the index, middle, and/or ring fingers... The C5, C6, and C7 roots are the ones most commonly involved in cervical spondylosis."

• Bradley and Daroff's Neurology in Clinical Practice

The "Phone Neck" Connection (Text Neck / Cervical Flexion)

• The cervical neural foramina narrow further, increasing root compression
• The weight load on the cervical spine increases dramatically (from ~5 kg at neutral to ~27 kg at 45° flexion)
• Disc material is pushed posteriorly toward the nerve roots
• The dura and nerve roots are stretched, especially C6 and C7

Diagnosis

• Spurling's test - neck extension + rotation to the affected side + axial compression reproduces arm pain (opposite of your flexion trigger)
• Distraction test - lifting the head reduces pain (decompresses the foramen)
• Check for dermatomal sensory loss, muscle weakness, and reflex changes per the table above

• MRI cervical spine - first-line; identifies disc herniation, foraminal stenosis, cord compression. Must be interpreted alongside clinical findings as degenerative changes are common even in asymptomatic spines
• CT myelography - used when MRI is contraindicated (pacemakers, prior fusion hardware) or when distinguishing osteophytes from soft disc herniation

• EMG / Nerve conduction studies (NCS) - the classic pattern in radiculopathy is reduced compound muscle action potential (CMAP) amplitude but preserved sensory nerve action potential (SNAP), because the compression is proximal to the dorsal root ganglion. This helps distinguish radiculopathy from brachial plexopathy or peripheral neuropathy

Differential Diagnoses to Consider

• Cervical myelopathy - cord compression; presents with Lhermitte's sign, upper motor neuron signs (hyperreflexia, clonus, Hoffman's sign), gait disturbance - more serious, requires urgent surgery
• Thoracic outlet syndrome - compression of brachial plexus or C8/T1 roots, causing numbness in 4th and 5th digits
• Carpal tunnel syndrome - median nerve compression at the wrist (mimics C6 distribution)
• Brachial neuritis (Parsonage-Turner syndrome) - sudden severe shoulder pain followed by weakness and wasting
• Ulnar neuropathy - causes ring and little finger symptoms (mimics C8)

Treatment

Conservative (First-Line, Most Cases Improve)

Surgical (Reserved for Specific Indications)

• Progressive motor deficit due to nerve root compression
• Functionally limiting pain that fails to respond to conservative management
• Spinal cord compression (myelopathy)

• Anterior cervical discectomy and fusion (ACDF) - most common; removes disc and fuses the level
• Cervical disc arthroplasty (artificial disc replacement) - preserves motion; alternative to fusion in selected patients
• Posterior cervical laminectomy / laminoplasty - for multilevel disease or myelopathy

Note: The risk of radiculopathy or myelopathy at adjacent levels after fusion is approximately 3% per year and 26% per decade.

Practical Advice for the Patient

1. Reduce phone/tablet neck flexion - hold devices at eye level; use a stand or mount
2. Ergonomic workstation - monitor at eye level, chair with neck support
3. Avoid prolonged postures in neck flexion
4. Seek urgent evaluation if you develop: weakness in the hands/arms, loss of bladder or bowel control, bilateral symptoms, or progressive neurological changes - these may indicate myelopathy

Anatomy - C6 Nerve Root Path

Brachial Plexus - C6 Downstream Pathway

Physiotherapy Treatment Plan - Step by Step

Phase 1 - Acute/Pain Relief Phase (Weeks 1-2)

1. Postural Education (Most Important Step)

• Phone hygiene - hold device at eye level, not looking down
• Avoid prolonged neck flexion beyond 15-20°
• Ergonomic setup: monitor at eye height, chair with headrest support
• "Chin tuck" awareness to maintain neutral cervical curve

2. Cervical Traction

• Mechanical or manual cervical traction - opens the C5-C6 neural foramen, directly decompresses the C6 root
• Home cervical traction devices can be prescribed (over-door traction or inflatable collar)
• Applied at ~10-15° of flexion for 15-20 minutes
• Evidence: neural mobilisation was found no more effective than cervical traction for pain and disability reduction (Lascurain-Aguirrebebeña et al., Pain, 2024 [PMID 37870223])

3. Electrophysical Modalities

• TENS (Transcutaneous Electrical Nerve Stimulation) over the cervical region - pain gate mechanism
• Ultrasound therapy over C5-C6 paravertebral area - reduces local inflammation
• Heat pack (moist heat) to cervical paraspinals before exercise - relaxes muscle guarding
• Ice pack after exercises if there is local soreness

4. Soft Cervical Collar

• Short-term use (1-2 weeks, not continuous) during activities that provoke symptoms
• Limits cervical flexion that compresses the C6 root

Phase 2 - Mobilization & Neural Gliding Phase (Weeks 2-4)

5. Neural Mobilisation / Nerve Gliding (Median Nerve Bias - C6)

1. Sit upright, arm at side
2. Slowly depress shoulder + extend elbow + supinate forearm + extend wrist + extend fingers
3. At first onset of sensation, stop and return
4. Perform 10-15 gentle oscillations
5. Do NOT push into pain - this is a slider, not a tensioner

6. Manual Therapy - Cervical Joint Mobilisation

• Maitland Grade I-II mobilisations at C5-C6 (oscillatory, gentle, below pain threshold)
• Reduces joint stiffness and reflex muscle guarding around the compressed foramen
• Manual physical therapy shows consistent benefit for neck disorders (Reynolds et al., J Man Manip Ther, 2025, PMID 39607420)
• Avoid high-velocity manipulation in the acute phase with radiculopathy

7. Soft Tissue / Myofascial Release

• Release of cervical paraspinals, upper trapezius, scalenes (which can secondarily compress the brachial plexus)
• Levator scapulae and suboccipital release
• RCT evidence supports myofascial release for reducing pain in unilateral cervical radiculopathy (Bali & Bayram, Explore, 2024, PMID 38296722)

Phase 3 - Strengthening & Stabilisation Phase (Weeks 4-8)

8. Deep Cervical Flexor Strengthening

• Chin tuck exercise (craniocervical flexion) - the most evidence-based exercise for cervical radiculopathy
• Activates longus colli and longus capitis (deep stabilisers)
• 10-second holds × 10 repetitions, 2-3 sets daily
• Reduces mechanical load on posterior elements including C5-C6 foramen

9. Cervical Range-of-Motion Exercises

• Gentle active rotation, lateral flexion, extension - within pain-free range
• Avoid sustained neck flexion as an exercise
• Progress to resisted rotation with Thera-Band

10. Scapular Stabilisation

• Scapular retraction exercises (rows, shoulder blade squeezes)
• Lower trapezius activation: "Y" and "T" exercises in prone position
• Strengthens the periscapular muscles that support the cervicothoracic junction and reduce upper-extremity strain

11. Upper Limb / Biceps-Focused Strengthening (C6 targets)

• Light resistance bicep curls (C6 motor = biceps, brachioradialis)
• Wrist extension with Thera-Band (ECRL/ECRB = C6)
• Start with low load to avoid Valsalva-type pressure that worsens radicular pain

12. McKenzie Method

• Cervical retraction (chin tucks) and extension exercises
• Particularly useful when symptoms have a directional preference (less pain in extension than flexion)

Phase 4 - Functional Return & Maintenance (Weeks 8-12+)

• Progressive strengthening with full range of motion
• Sport/work-specific movements
• Ergonomic reassessment
• Home exercise program for long-term maintenance
• Education on avoiding repetitive/sustained neck flexion

Recovery Timeline

For mild cervical radiculopathy (your case), the natural history is very favorable. Most patients improve significantly within 4-8 weeks of physiotherapy. Complete symptom resolution (especially the finger tingling) may take 3-6 months as the nerve heals.

• Harrison's Principles of Internal Medicine, 22nd Ed.

• Starting physiotherapy early
• Correcting the posture trigger (phone use) immediately
• No motor weakness (mild = better prognosis)
• Younger age
• Soft disc herniation (vs. hard osteophyte)

Red Flags - Seek Urgent Medical Attention

• Weakness develops in the hand or arm
• Symptoms spread to both arms or legs
• Bladder or bowel changes appear
• Symptoms worsen significantly with physiotherapy
• You develop balance problems or walking difficulty (suggests myelopathy)

Summary: The Key Points

1. Nerve involved: C6 root (C5-C6 disc level) - travels to thumb and index finger
2. Cause: Disc herniation or foraminal narrowing at C5-C6, aggravated by neck flexion
3. First physiotherapy priority: Stop the trigger - raise phone/device to eye level TODAY
4. Most effective physiotherapy: Cervical traction + neural mobilisation (median nerve gliding) + deep cervical flexor strengthening
5. Recovery: 4-8 weeks for significant improvement; full nerve recovery 3-6 months
