Cervical Osteoarthritis

Cervical osteoarthritis is a degenerative condition of the cervical spine, leading to pain, stiffness and potential nerve compression. Once seen as purely degenerative, it is now recognized as an active process that can be managed. It becomes more prevalent with age, especially in women over 50, contributing to chronic neck pain, one of the most common musculoskeletal complaints.

Beyond pain, it affects proprioception, motor function and muscle balance, potentially leading to headaches, brachalgia and gait disturbances. Addressing sensory deficits, neuromuscular coordination and joint stability is key to effective management.

 

How Nerve Compression Worsens Joint Instability and Pain?

It also involves neuromotor dysfunction, affecting muscle control, nerve responses and movement coordination, leading to chronic pain and instability.

• Neuromotor Dysfunction - nerve compression disrupts muscle activation, increasing joint instability and pain.
• Cervical Spine Vulnerability - loss of disc height and ligament weakening worsen degeneration and can impact other joints.
• Muscle & Nerve Involvement - muscle imbalances and proprioceptive deficits impair movement control, sometimes leading to chronic pain syndromes.

Shifting from a degenerative view to a neuromotor focus can improve rehabilitation, reducing pain and enhancing mobility. 

 

Neuromotor & Proprioceptive Aspects of Cervical Osteoarthritis

Cervical osteoarthritis disrupts joint sensory input, leading to pain, dizziness, instability and impaired movement.

• Joint Sensory Receptors - dysfunctional mechanoreceptors affect pain, proprioception and postural control, contributing to vertigo and muscle fatigue.
• Pain & Instability - inflammation lowers mechanoreceptor thresholds, prolonging pain and reducing joint stability.
• Sensorimotor Dysfunction - impaired proprioception affects posture, balance, gait and eye movement, worsening chronic pain.
• Ligament Laxity & Neurological Symptoms - weak ligaments cause excessive motion, nerve irritation, vertigo, tinnitus and paresthesia.
• Muscle Imbalances - chronic neck pain leads to muscle fatigue, imbalance and impaired joint position sense.
• Balance & Gait Issues - proprioceptive deficits increase postural instability, dizziness and fall risk.

Assessing and managing proprioceptive deficits is key to reducing pain, improving function and preventing joint degeneration.

Physiotherapy Management of Cervical Osteoarthritis 

Physiotherapy plays a crucial role in it's management by reducing pain, improving mobility, strengthening muscles and enhancing function. This comprehensive management approach includes physical modalities, manual therapy, exercise therapy, neuromuscular techniques and lifestyle modifications.

1. Patient Education

Educating patients about the nature of COA, its progression and the role of physiotherapy is fundamental to improving compliance and outcomes.

• Explain the degenerative nature of osteoarthritis and emphasize the importance of maintaining movement.
• Advise on postural correction (e.g., maintaining a neutral spine while sitting, using a lumbar roll for support).
• Provide guidance on ergonomic modifications, such as adjusting desk height, using supportive pillows and avoiding prolonged flexed neck positions [Binder, 2007].
• Encourage activity modification to reduce excessive strain on the cervical spine while maintaining an active lifestyle [Côté et al., 2008].

2. Pain Management Techniques

A. Manual Therapy

Manual therapy is effective in reducing pain, improving joint mobility and addressing soft tissue restrictions.

• Soft tissue release for cervical and upper trapezius muscle tightness [Falla et al., 2012].
  
• Joint mobilizations (Grade I-II) to reduce stiffness and improve movement [Gross et al., 2015].
  
• Cervical traction (manual or mechanical) to relieve nerve compression and disc pressure [Moeti & Marchetti, 2001].
• Post-isometric relaxation (PIR) techniques to reduce muscle tension and improve range of motion [Jull et al., 2008].

B. Modalities

Physical modalities help reduce pain and inflammation and prepare tissues for exercise.

• Heat therapy (hot packs) to relax tight muscles and improve circulation [Kumar et al., 2019].
• Cryotherapy (cold packs) for acute inflammation or pain relief [Malanga et al., 2015].
• Therapeutic Ultrasound to reduce deep tissue inflammation and improve tissue healing [Ebadi et al., 2014].
• TranscutaneousElectrical Nerve Stimulation (TENS) for pain modulation and reduction in radicular symptoms [Nnoaham & Kumbang, 2008].
• Low-powerlaser therapy (LPL) for reducing pain and improving function in COA [Kulekci et al., 2013].
• Pulsed Electromagnetic Field (PEMF) Therapy to improve pain, ROM and functional status.

 

3. Exercise Therapy

Exercise is the cornerstone of cervical osteoarthritis rehabilitation, focusing on mobility, strength and postural correction.

A. Mobility & Stretching Exercises

• Neck Rotations - maintains cervical mobility and prevents stiffness.
• Neck Side Bends & Forward/Backward Bends - improves flexibility.
• Upper Trapezius & Levator Scapulae Stretch - reduces muscle tightness [Jull et al., 2008].
• Pectoral Stretch - opens up the chest to counteract forward head posture.

B. Strengthening Exercises

• Deep Neck Flexor Strengthening (e.g., Chin tuck isometrics, supine head lifts) [Falla et al., 2007].
• Scapular Strengthening (e.g., Scapular retractions, rows) [Waling et al., 2000].
• Isometric Neck Strengthening - gentle resistance exercises for flexion, extension, and lateral movements [Ylinen et al., 2010].
• Resistance Band Exercises - strengthens upper back and neck stabilizers [Gross et al., 2015].

C. Postural Training

• Wall Angel Exercise - improves upper back and cervical posture.
• Postural Awareness Drills - using a mirror or kinesio-taping techniques to maintain proper alignment [Lee et al., 2017].

 

4. Neuromuscular Techniques

Neuromuscular re-education plays a key role in improving motor control and reducing pain.

• Electroacupuncture and Acupuncture - modulates pain and improves neuromuscular activation [Vickers et al., 2012].
• Neuromuscular Electrical Stimulation (NMES) - improves muscle recruitment and reduces atrophy [Hains et al., 2010].
• Proprioceptive Neuromuscular Facilitation (PNF) - enhances motor control, flexibility and strength through functional movement patterns [Sharman et al., 2006].

Research-Backed Approaches in Physiotherapy

Proprioceptive Neuromuscular Facilitation (PNF) - it enhances motor learning and control using functional movement patterns.

Techniques:

• Combination of isotonics
• Rhythmic stabilization
• Dynamic reversals
• Hold-relax techniques

Focus is on strengthening through pain-free movements while avoiding fatigue.

Manual Therapy (MAN.T) Based on Kaltenborn-Evjenth Approach - focus on restoring normal joint play and improving segmental motion.

Techniques Used:

• Joint mobilization (flexion, extension, coupling movements)
• Post-isometric muscle relaxation
• Cervical traction & mobilization
• Isometric exercises for neck muscles
• Grade III gliding therapy

PNF provides long-term benefits even after 3 months, while manual therapy results are often short-lived. Patients undergoing PNF reported higher post-treatment quality of life.

 

5. Functional Training & Ergonomics

Functional retraining ensures the patient can maintain improvements in daily life.

• Workplace Ergonomics - adjusting screen height, chair support and keyboard positioning [Côté et al., 2008].
• Sleeping Position Adjustments - using a cervical pillow to maintain a neutral spine [Kumar et al., 2019].
• Lifting Techniques - proper head and neck positioning while carrying objects to prevent excessive strain.

 

6. Balance & Proprioception Training

For patients with cervical proprioceptive dysfunction, dizziness, or balance issues, the following techniques may be beneficial:

• Gaze Stability Exercises - improves head and eye coordination [Hall et al., 2010].
• VestibularRehabilitation - beneficial for patients with associated dizziness or vertigo [Reid et al., 2017].

 

7. Lifestyle Modifications & Home Program

Encouraging an active lifestyle and self-management strategies is crucial for long-term outcomes.

• Low-impact aerobic activities (e.g., walking, swimming, cycling) improve circulation and reduce stiffness.
• Avoid prolonged static postures (e.g., looking down at a phone for long periods).
• Stress management techniques (e.g., diaphragmatic breathing, meditation) help reduce muscle tension [Goyal et al., 2014]. 

Long-term management of cervical osteoarthritis requires monitoring for mechanoreceptor and proprioceptive deficits, as symptoms may not always correlate with radiographic findings. Minimizing opioid and corticosteroid use is essential, with a focus on non-pharmacological treatments like physiotherapy, exercise and manual therapy.
