Cervical Radiculopathy
Introduction
- Cervical radiculopathy includes cervical radicular pain and/or radiculopathy, with disc herniation being the most common cause.
- Radicular pain involves ectopic discharges from a dorsal root, while radiculopathy involves conduction block along a spinal nerve or its roots
Epidemiology
- Mechanical compression of the nerve root by factors like hypertrophied facet joints, disc protrusion, or spondylotic spurring leads to radiculopathy.
- Incidence: Annual incidence of 82.3 new cases per 100,000 people, with males (107) more affected than females (64); C7 nerve root most commonly affected.
Clinical Picture
-
Signs & symptoms include varying degrees of arm pain, paresthesia, sensory loss, motor weakness, and decreased reflexes, often with neck pain of lesser intensity.
Examination
- Tests include Upper Limb Tension Tests, Spurling’s Test, Cluster of Wainner, Cervical Distraction Test, Shoulder Abduction Sign, Valsalva Maneuver, Arm Squeeze Test, and Neck Tornado Test.
- Neurological examination focuses on assessing hyporeflexia, hypoesthesia, and paresis using Upper Limb Deep Tendon Reflexes and dermatome/myotome testing.
Treatment
- Treatment aims to address modifiable negative prognostic factors and educate patients about the benign course of cervical radicular syndrome.
- Physiotherapy interventions focus on pain reduction, disability management, and improving range of motion and joint mobility.
- Manual therapy, neck and upper limb strengthening exercises, thoracic manipulation, neural tissue management, and nerve gliding exercises are effective treatments.
- Cervical traction may be considered, especially when added to other physiotherapy procedures, for pain reduction.
- Surgical treatment may show more rapid improvement in the short term but yields similar long-term results to physiotherapy alone, suggesting physiotherapy should precede surgery.
