Abstract

Cervical spondylosis represents a spectrum of age- and mechanically associated degenerative changes involving the intervertebral discs, vertebral bodies, facet joints, ligaments and surrounding soft tissues of the cervical spine. Although radiological degeneration may remain asymptomatic, clinically significant disease may manifest as axial neck pain, cervical radiculopathy, cervical myelopathy, or a combination of these manifestations. Radiculopathy primarily reflects compromise of cervical nerve roots, commonly through foraminal narrowing, whereas myelopathy results from dysfunction of the cervical spinal cord secondary to canal narrowing and static or dynamic compression.

Ayurveda does not describe cervical spondylosis as a direct equivalent of a single modern diagnostic entity. However, its conceptual framework of Vāta prakopa, dhātu kṣaya, asthi-majjā dhātu, snāyu, sandhi, māṃsa, srotoduṣṭi and mārga-āvaraṇa provides a potentially useful framework for interpreting different clinical phenotypes of degenerative cervical disease.

The present article proposes an integrative clinico-pathophysiological model in which the degenerative and mechanical components of cervical spondylosis are considered alongside Ayurvedic concepts of structural degeneration, altered tissue function, obstruction and Vāta dysfunction. A phase-wise Ayurvedic therapeutic strategy is proposed, consisting initially of rukṣa and svedana-oriented measures with selected decoctions and external applications, followed by snehana, nasya, basti and Vāta-pacifying interventions in the appropriate clinical phenotype.

The proposed model is intended to facilitate clinical reasoning and hypothesis generation rather than establish equivalence between modern neurological diagnoses and Ayurvedic disease categories. Patients with progressive neurological deficit, significant myelopathy or radiological spinal-cord compression require appropriate neurological/spinal evaluation and should not have potentially necessary surgical management delayed in favour of conservative therapy.

1. Introduction

Cervical spondylosis is a degenerative disorder involving multiple anatomical structures of the cervical spine. Disc degeneration, loss of disc height, osteophyte formation, facet arthropathy, ligamentous hypertrophy and changes in spinal alignment may progressively alter the dimensions of the intervertebral foramina and spinal canal. These changes may produce three major clinical phenotypes: axial neck pain, cervical radiculopathy and cervical myelopathy.

The clinical significance of cervical spondylosis therefore extends beyond local pain. Foraminal compromise may affect a cervical nerve root and produce radicular pain, paraesthesia, sensory alteration and motor weakness. Central canal compromise may affect the spinal cord and produce cervical myelopathy, characterized by upper-limb dysfunction, gait disturbance, impaired dexterity, hyperreflexia and other long-tract neurological manifestations.

From an Ayurvedic perspective, chronic degenerative disorders are frequently interpreted through the interaction of Vāta, tissue depletion and obstruction of physiological pathways. Nevertheless, a responsible integrative interpretation should not claim that cervical spondylosis is literally described in the classical texts as a modern anatomical diagnosis.

The objective, therefore, is not to establish a simplistic disease equivalence but to construct a clinically meaningful bridge between the two systems.

2. Modern Understanding of Cervical Spondylosis

2.1 Degenerative cascade

The degenerative process commonly begins with biochemical and structural alteration of the intervertebral disc. Progressive disc dehydration and loss of disc height increase mechanical loading on adjacent structures. Osteophyte formation, facet-joint degeneration, ligamentous changes and altered spinal biomechanics subsequently contribute to narrowing of the neural foramina and/or spinal canal.

Thus:

Disc degeneration → loss of disc height → altered biomechanics → osteophyte formation/facet degeneration/ligamentous changes → foraminal or canal narrowing → neural compromise

The radiological presence of spondylosis, however, does not automatically indicate symptomatic disease. Degenerative findings are common even among asymptomatic individuals.

---

3. Cervical Radiculopathy

Cervical radiculopathy refers to dysfunction of a cervical nerve root, generally caused by foraminal narrowing from disc degeneration, disc herniation, osteophytes or combinations of these factors.

Clinical manifestations may include:

• Neck pain radiating into the upper limb
• Dermatomal pain
• Paraesthesia or numbness
• Myotomal weakness
• Altered reflexes
• Provocative-test positivity
• Functional limitation of the upper limb

The pathological sequence may be represented as:

Foraminal narrowing → nerve-root compression/irritation → mechanical and inflammatory neural dysfunction → radicular pain and neurological symptoms

The natural history of cervical radiculopathy is often more favourable than that of established myelopathy, and many patients improve with conservative management.

---

4. Cervical Myelopathy

Cervical myelopathy represents dysfunction of the spinal cord caused by cervical canal compromise.

The pathology is not simply mechanical compression. Static compression may be accompanied by repetitive dynamic trauma and vascular compromise, resulting in spinal-cord ischemia, demyelination and axonal injury.

Important clinical manifestations include:

• Loss of hand dexterity
• Difficulty with fine motor activities
• Weakness of the upper or lower limbs
• Gait imbalance
• Stiff or spastic gait
• Hyperreflexia
• Pathological reflexes
• Sensory disturbances
• Difficulty climbing stairs
• In advanced disease, bladder or bowel dysfunction

A particularly important clinical principle is that myelopathy is not merely an extension of neck pain. It represents neurological dysfunction and therefore changes the clinical risk profile.

Progressive or moderate-to-severe degenerative cervical myelopathy generally requires specialist spinal evaluation, and delaying appropriate surgical treatment can adversely affect neurological recovery.

---

5. Myeloradiculopathy

Some patients demonstrate simultaneous nerve-root and spinal-cord involvement.

This can be conceptualized as:

Cervical degeneration → foraminal stenosis + central canal stenosis → radiculopathy + myelopathy

Such patients may present with a mixture of:

• Radicular pain
• Sensory symptoms in a dermatomal distribution
• Hand weakness
• Loss of dexterity
• Gait disturbance
• Upper motor neuron signs

The term cervical myeloradiculopathy is therefore useful for describing this combined phenotype.

---

6. Diagnostic Evaluation

Diagnosis should integrate:

Clinical examination

• Pain assessment
• Cervical range of motion
• Dermatomal sensory examination
• Myotomal motor examination
• Deep tendon reflexes
• Upper motor neuron signs
• Gait examination
• Hand dexterity
• Coordination
• Balance

Imaging

MRI cervical spine is particularly important when neurological symptoms or myelopathic features are present because it demonstrates:

• Disc pathology
• Foraminal stenosis
• Central canal stenosis
• Cord compression
• Cord signal changes
• Soft-tissue pathology

MRI is particularly important in suspected cervical myelopathy.

Functional assessment

For research purposes, standardized neurological and functional measures should be incorporated, such as:

• Neck Disability Index
• Visual Analog Scale/Numerical Rating Scale
• Modified Japanese Orthopaedic Association score
• Nurick grade
• Grip strength
• Timed functional tests
• Cervical range of motion
• Neurological examination

7. Ayurvedic Conceptual Framework

7.1 Why a direct disease equivalence should be avoided

Cervical spondylosis is an anatomical-radiological diagnosis developed within modern medicine. Ayurveda organizes disease primarily through doṣa, dūṣya, srotas, agni, āma, samprāpti and clinical phenotype.

Therefore:

Cervical spondylosis ≠ a single classical Ayurvedic disease.

Instead, its manifestations may be interpreted through overlapping Ayurvedic principles.

The dominant conceptual components may include:

Vāta prakopa + dhātu kṣaya + asthi/sandhi/snāyu involvement + māṃsa dysfunction ± āma/kapha involvement + srotorodha/āvaraṇa

The relative dominance of these components should be assessed individually.

---

8. Vāta and Degenerative Change

Vāta is characterized by rūkṣa, laghu, śīta, khara, sūkṣma and cala qualities.

Chronic degeneration may be conceptually associated with:

• Rūkṣatā → tissue dryness/depletion
• Khara quality → structural irregularity
• Cala → abnormal movement/instability
• Śūla → pain
• Stambha → stiffness
• Suptatā → altered sensation
• Daurbalya → weakness

Thus, the chronic degenerative phenotype can be conceptualized as predominantly Vāta-associated dhātu kṣaya.

---

9. Asthi–Majjā–Snāyu–Sandhi Involvement

The cervical spine represents a complex anatomical relationship between:

Asthi + Sandhi + Snāyu + Majjā + Māṃsa

Modern cervical spondylosis involves vertebral structures, intervertebral discs, facet joints, ligaments, musculature and neural tissues.

An Ayurvedic interpretive model may therefore consider:

Modern component	Ayurvedic conceptual domain
Vertebral degeneration	Asthi dhātu
Facet/vertebral articulation	Sandhi
Ligamentous structures	Snāyu
Muscular dysfunction	Māṃsa
Neural/spinal-cord involvement	Majjā-oriented conceptual interpretation
Pain/stiffness	Vāta
Swelling/inflammatory phenotype	Kapha/Pitta association
Metabolic/inflammatory component	Āma, when clinically appropriate

These are conceptual correlations rather than anatomical equivalences.

---

10. Proposed Ayurvedic Samprāpti

A clinically useful integrative model may be expressed as:

Nidāna sevana

↓

Vāta prakopa ± Kapha/Āma association

↓

Agni dysfunction / metabolic disturbance

↓

Dhātu kṣaya and/or srotorodha

↓

Asthi–Sandhi–Snāyu–Māṃsa involvement

↓

Cervical structural degeneration and functional restriction

↓

Mārga-āvaraṇa / neural pathway compromise

↓

Śūla + Stambha + Suptatā + Daurbalya

↓

Radiculopathic phenotype

and, when central neural structures are involved:

Spinal-cord dysfunction / myelopathic phenotype

This model should be viewed as a hypothesis-generating Ayurvedic interpretation, not as a proven molecular mechanism.

---

11. Phenotype-Based Ayurvedic Assessment

Rather than treating every patient with cervical spondylosis identically, patients may be clinically stratified.

Phenotype A — Rūkṣa/Vāta-Kapha dominant

Features:

• Stiffness
• Heaviness
• Restricted movement
• Local tenderness
• Chronic pain
• Muscular tightness
• Possible inflammatory/congestive features

Phenotype B — Predominantly Vāta-kṣaya

Features:

• Chronic degenerative pain
• Dryness
• Stiffness
• Weakness
• Reduced tissue bulk
• Neurological symptoms without prominent inflammatory features

Phenotype C — Radiculopathic phenotype

Features:

• Radiating pain
• Paraesthesia
• Dermatomal symptoms
• Myotomal weakness
• Reflex alteration

Phenotype D — Myelopathic phenotype

Features:

• Gait dysfunction
• Hand clumsiness
• Hyperreflexia
• Long-tract signs
• Progressive weakness
• Balance disturbance

Phenotype D requires neurological/spinal evaluation and cannot be managed solely as a routine Vāta disorder.

---

12. Proposed Phase-Wise Ayurvedic Management

The proposed protocol is divided into two therapeutic phases.

Phase I — Rūkṣa–Śodhana/Śamana-oriented phase

Therapeutic objective

The first phase is intended for patients presenting with a relatively āma/Kapha-associated, heavy, stiff, congestive or inflammatory phenotype, where immediate intensive snehana may not be appropriate.

The objectives are:

• Reduce gaurava
• Reduce stiffness
• Improve local mobility
• Address āma/Kapha predominance when clinically present
• Reduce pain and local inflammatory burden
• Prepare the patient for subsequent snehana

Internal medicines

The proposed decoction-based options are:

1. Rasna Saptakam Kashayam

2. Rasna Sundhyadi Kashayam

Selection should be individualized according to the patient’s doṣa, āma, agni, pain phenotype and associated symptoms.

The Government of India’s Ayurveda Standard Treatment Guidelines for musculoskeletal disorders list Rasnasaptakam among the formulations used in cervical spondylosis, although this does not constitute high-level evidence for efficacy in cervical myelopathy.

---

External therapies

Rūkṣa Swedana

Rūkṣa swedana may be considered when heaviness, stiffness and Kapha/Āma characteristics predominate.

Rūkṣa Piṇḍa Sweda

A dry herbal powder bolus may be used as a localized fomentation procedure.

The Ministry of AYUSH/DGHS musculoskeletal guidelines include rūkṣa cūrṇa piṇḍa sweda among procedures described for cervical spondylosis.

Lepa

The following may be considered according to phenotype:

• Kolakulathādi Cūrṇa
• Kottamchukkādi Cūrṇa
• Nagarādi Cūrṇa

These may be applied as appropriate local lepa/upanāha-type interventions.

The Government of India’s musculoskeletal guidance specifically lists Kottamchukkadi Lepa and Nagaradi Lepana among external options for cervical spondylosis.

---

13. Phase II — Snehana and Vāta-Pacifying Phase

After adequate reduction of stiffness/heaviness and where the clinical phenotype is predominantly Vāta or degenerative, treatment may progress toward snehana and Vāta-pacifying measures.

Internal medicines

Proposed options:

1. Dhanwantharam Kashayam

2. Prasaranyadi Kashayam

The selection should be based on the patient’s presentation rather than automatically combining multiple decoctions.

---

14. Snehana

The second phase may incorporate:

Abhyanga

Appropriate medicated oils may be selected according to:

• Vāta predominance
• Muscle stiffness
• Neuromuscular weakness
• Chronicity
• Tissue depletion

Proposed oils include:

Dhanwantharam Taila

Karpāsāsthyādi Taila

Uttama Taila

Other oils may be selected according to the individual phenotype.

Government Ayurveda guidance for cervical spondylosis also describes medicated-oil applications including Dhanwantaram Taila and Karpasasthyadi Taila.

---

15. Nasya and Basti

The second phase may include Nasya and Basti when clinically appropriate.

Nasya

Nasya may be considered particularly when symptoms are predominantly located in the head, neck and upper cervical region.

The Ayurvedic rationale is based on the classical therapeutic concept of administering medicines through the nasal route for disorders involving structures above the clavicle.

Basti

Basti may be considered in chronic Vāta-dominant presentations.

Possible approaches include:

• Mātrā Basti
• Anuvāsana Basti
• Appropriate Niruha Basti according to the patient’s condition

The selection should be individualized rather than applying a fixed Panchakarma protocol to all patients.

Government Ayurveda guidance describes Nasya and Basti among Panchakarma options in musculoskeletal disorders including cervical spondylosis.

---

16. Proposed Two-Phase Treatment Algorithm

PHASE I

Clinical phenotype

Rūkṣa + Stambha + Gaurava + Kapha/Āma association

↓

Internal

Rasna Saptakam Kashayam
± Rasna Sundhyadi Kashayam

↓

External

Rūkṣa Sweda
Rūkṣa Piṇḍa Sweda

↓

Lepa

Kolakulathādi
Kottamchukkādi
Nagarādi

↓

Goal

Reduce stiffness, heaviness and pain
↓
Prepare for Snehana

---

PHASE II

Clinical phenotype

Vāta dominance + chronic degeneration + weakness/stiffness

↓

Internal

Dhanwantharam Kashayam
± Prasaranyadi Kashayam

↓

Snehana

Dhanwantharam Taila
Karpāsāsthyādi Taila
Uttama Taila

↓

Panchakarma

Nasya
Basti

↓

Goal

Vāta śamana + functional rehabilitation + tissue support

---

17. Integrative Interpretation of the Two Phases

The two-phase approach can be conceptually represented as:

Phase I: Reduce obstruction / stiffness

Āma-Kapha ↓
Gaurava ↓
Stambha ↓
Local inflammatory burden ↓
Mobility ↑

↓

Phase II: Restore Vāta balance / support function

Vāta ↓
Snehana ↑
Musculoskeletal function ↑
Neuromuscular rehabilitation ↑

This sequence is conceptually attractive because it follows the Ayurvedic therapeutic principle of avoiding indiscriminate snehana when āma and Kapha predominance are clinically evident, followed by Vāta-pacifying measures after the initial phase.

However, this proposed sequence requires prospective clinical validation.

---

18. Modern–Ayurvedic Integrative Model

A useful conceptual bridge is:

Degenerative disc disease
↓
Disc-space reduction / altered biomechanics
↓
Osteophyte + facet + ligamentous changes
↓
Foraminal narrowing
↓
Nerve-root dysfunction
↓

Radiculopathy

AND/OR

Central canal narrowing
↓
Static + dynamic cord compression
↓
Vascular compromise + neural injury
↓

Myelopathy

The Ayurvedic interpretive overlay can be:

Chronic Nidāna

↓

Vāta prakopa ± Kapha/Āma

↓

Dhātu kṣaya / Srotorodha

↓

Asthi–Sandhi–Snāyu–Māṃsa involvement

↓

Śūla + Stambha + Suptatā + Daurbalya

↓

Radiculopathic / myelopathic clinical phenotype

The two pathways should be regarded as parallel explanatory models, rather than claiming that one is a literal translation of the other.

---

19. Rehabilitation

Ayurvedic intervention should not be considered complete without rehabilitation.

Once acute pain and neurological irritability are controlled, an individualized rehabilitation program may include:

• Cervical posture correction
• Deep cervical flexor training
• Scapular stabilization
• Thoracic mobility
• Ergonomic correction
• Progressive strengthening
• Balance training when appropriate
• Hand-function rehabilitation
• Gait rehabilitation in selected patients

In myelopathy, rehabilitation should occur under appropriate neurological/spinal supervision.

---

20. Red Flags and Referral Criteria

An integrative Ayurvedic protocol must clearly define situations where referral takes priority.

Immediate specialist evaluation should be considered in patients with:

• Progressive limb weakness
• Progressive gait disturbance
• Hand clumsiness
• Hyperreflexia or pathological reflexes
• Significant balance impairment
• New bladder or bowel dysfunction
• Severe or rapidly progressive neurological symptoms
• Evidence of significant spinal-cord compression on MRI
• Cord signal abnormality
• Severe canal stenosis with neurological manifestations
• Acute trauma with neurological deficit

Degenerative cervical myelopathy can progress unpredictably, and established moderate or severe neurological disease may require surgical decompression.

Ayurvedic treatment should therefore be complementary to, and not a substitute for, appropriate neurosurgical/orthopaedic evaluation when myelopathy is clinically significant.

---

21. Discussion

The major strength of an Ayurvedic interpretation of cervical spondylosis lies not in attempting to reproduce modern anatomical terminology, but in providing a multidimensional assessment of the patient.

Modern medicine excels in identifying:

• Structural pathology
• Neural compression
• Neurological localization
• Radiological severity
• Surgical indications

Ayurveda contributes a different clinical language involving:

• Doṣa predominance
• Dhātu status
• Agni
• Āma
• Srotas
• Bala
• Chronicity
• Individual constitution and response

An integrative model may therefore be particularly useful in patients with chronic axial pain, stiffness and functional limitation, provided that neurological compromise has first been appropriately evaluated.

The distinction between radiculopathy and myelopathy is especially important. Radiculopathy may often have a favourable conservative course, whereas progressive myelopathy represents spinal-cord dysfunction and carries a different risk profile.

Therefore, Ayurvedic management should be phenotype-driven rather than diagnosis-label-driven.

---

22. Limitations

Several limitations must be acknowledged.

First, there is currently no universally accepted one-to-one mapping between cervical spondylosis and a classical Ayurvedic disease entity.

Second, the proposed samprāpti represents an interpretive model and should not be presented as established biological equivalence.

Third, evidence supporting specific Ayurvedic formulations and procedures for cervical radiculopathy and especially degenerative cervical myelopathy remains limited compared with the evidence base for modern neurological and surgical management.

Fourth, formulations, dose, duration, route and Panchakarma procedures should be individualized by a qualified Ayurvedic physician after clinical assessment.

Finally, patients with significant myelopathy should not be enrolled in conservative treatment studies without appropriate neurological assessment and predefined referral criteria.

---

23. Future Research Directions

The proposed model provides several opportunities for clinical research.

A prospective study could evaluate:

Population: MRI-confirmed cervical spondylosis with radiculopathy, without urgent surgical indication.

Intervention: Phase-wise Ayurvedic protocol.

Primary outcomes:

• Neck Disability Index
• Pain score
• Radicular pain score
• Neurological examination

Secondary outcomes:

• Cervical range of motion
• Grip strength
• Quality of life
• Functional hand tests
• Sleep disturbance
• Analgesic requirement

For patients with myelopathy:

• mJOA
• Nurick grade
• Gait parameters
• Hand dexterity
• Neurological progression

MRI findings should be used primarily for structural characterization rather than assuming that symptomatic improvement necessarily means reversal of anatomical degeneration.

A well-designed prospective controlled study would be required before the proposed phase-wise Ayurvedic protocol can be considered an evidence-based treatment standard.

---

24. Conclusion

Cervical spondylosis represents a spectrum of degenerative structural changes that may produce axial pain, radiculopathy, myelopathy or combined myeloradiculopathy. Modern medicine explains these manifestations through degenerative disc disease, osteophyte formation, foraminal stenosis, central canal narrowing and consequent neural compression, ischemia and neurological dysfunction.

Ayurveda provides a complementary conceptual framework in which chronic degeneration may be interpreted predominantly through Vāta, dhātu kṣaya, Asthi–Sandhi–Snāyu involvement and, depending upon the phenotype, Kapha, Āma and srotorodha.

A phase-wise approach may therefore be conceptualized:

Phase I:
Rūkṣa-oriented measures + Swedana + selected Kashaya + Lepa

Phase II:
Snehana + Nasya/Basti + Vāta-pacifying Kashaya + medicated oils + rehabilitation

Within this framework, Rasna Saptakam and Rasna Sundhyadi Kashayam may be considered in the initial phenotype-appropriate phase, while Dhanwantharam and Prasaranyadi Kashayam may be considered during the subsequent Vāta-oriented phase. External interventions may progress from Rūkṣa Sweda/Rūkṣa Piṇḍa Sweda and selected Lepa to Snehana using oils such as Dhanwantharam Taila, Karpāsāsthyādi Taila and Uttama Taila.

The central principle, however, is not to treat the MRI report alone, nor to treat cervical spondylosis simply as a Vāta disorder. Treatment should be based on the clinical phenotype, neurological status, structural severity, doṣa-dūṣya assessment and response to therapy.

Most importantly, progressive neurological deficit and clinically significant cervical myelopathy require timely specialist spinal evaluation. An integrative Ayurvedic approach should complement appropriate modern neurological and surgical care rather than delay it.
