Introduction

A thorough assessment is vital for the effective management of any condition. The cervical spine is no different. In this course Shala Cunningham gives a step-by-step overview of the vital elements of a thorough assessment of the cervical spine. The assessment should broadly consist of a subjective assessment (history taking) and an objective assessment (observation and tests). A thorough assessment allows the clinician to classify the client's presentation. A classification system is discussed to guide the clinician for the successful management of the client's presentation.

Subjective Assessment

History

In this course the instructor suggests using the mnemonic L-M-N-O-P-Q-R-S-T to cover all the aspects of the history taking in the subjective assessment.

L:  Location of symptoms and level of functional impairment

This table gives a summary of the likely source of symptoms based on the area of symptoms.

Table 1. Likely source of symptoms based on area of symptoms

Area of Symptoms	Possible Source of Symptoms
Head / occipital region	Upper cervical spine
Localised pain without radiation / referral	Muscle pain Facet pain Facet impingement
Radiating pain	Nerve root irritation

M: Medical factors (medications) and mechanism of injury

In the assessment, be specific in finding out when and how the injury occurred, what forces were applied, and the position of the head at the time of the trauma. Also ask about neurological symptoms with the trauma. Red flags related to the mechanism of injury would be sudden onset of severe pain in the absence of an incident or accident.

N: Neurological symptoms

Establish if there are symptoms of numbness, tingling, burning or electrifying. Be specific about the location of these symptoms i.e. is the distribution of these symptoms dermatomal? The clinician should also note if the symptoms are constant or intermittent, and if they are associated with the position of the head.

O: Occupation including limitations

P: Palliating and provocating symptoms

Establish what increases and decreases the symptoms. Also note how long it takes the symptoms to calm down once aggravated. A red flag would be constant/unrelenting pain independent of position or activity.

Q: Quality of symptoms/pain

This would cover the description of the symptoms for example, sharp, dull, stabbing, aching or electric/shock-like description of symptoms.

R: Radiation of symptoms

Be specific about where the symptoms radiate to, how long do the radiating symptoms last, and are they constant or position/activity related. A red flag would be if the radiating symptoms cover multiple dermatomes.

S: Severity of symptoms

Note how the symptoms impact function and activity.

T: Timing of symptoms

Ask about the sequence and progression of symptoms. Red flags would be if pain is interrupting sleep, or constant/unrelenting pain.

Be sure to inclde questions about age, past history of neck pain, constitutional symptoms, dizziness, drop attacks and vertigo, parasthesia, numbness, weakness, or stiffness.

Red Flags

Red flags are symptoms that suggest the presence serious pathology. International guidelines recommend using red flags to identify serious pathology. Below are a list of red flags to screen for when assessing the cervical spine:

• Severe loss of range of motion (ROM) with sudden onset of symptoms
• Changes in balance/ gait
• Hypo/ hyper reflexia
• Constant pain
• Severe radiating pain
• Moderate to severe occipital headache
• Facial pain
• Psychological changes
• Cranial nerve symptoms
• Dizziness
• Horner syndrome
• Hemiparaesthesia
• Bowel and bladder change
• Ataxia
• Nystagmus
• Drop attacks
• Hemifacial parathaesia
• Dysphagia

The History Can Be Suggestive of Certain Conditions

History Suggesting Cervical Spondylosis

A history suggestive of cervical spondylosis would include a person over the age of 45 years with gradual, slow onset of symptoms (no specific incident). The pain is usually unilateral and radiates in a facet joint referral pattern. Pain usually increases with extension ('closing down' of the joint) and reduces with flexion ('opening' of the joint). The most commonly affected levels of the cervical spine are C5,C6, C7.

Facet Joint Referral Pattern

History Suggesting Disc Involvement

A history suggestive of cervical disc involvement would include a person under the age of 60 years, with sudden onset of symptoms (no specific incident). The pain is usually unilateral and radiates in a dermatomal referral pattern. Pain usually increases with flexion. The most commonly affected levels of the cervical spine are C5,C6.

Dermatomes of the Upper Limb

Outcome Measures

Useful outcome measures in the assessment of the cervical spine:

• Neck Disability Index (NDI)
• Patient Specific Functional Scale (PSFS)
• Fear-Avoidance Belief Questionnaire (FABQ)
• Numeric Pain Rating Scale (NPRS)

Objective Assessment

Observation

General observation of the posture, including the position of the head, neck, and shoulders should be done. Also observe for any signs of torticollis.

Instability Testing

The Sharp-Purser test is used to test the integrity of the transverse ligament, however there are concerns about the reliability, validity and safety of the test.

Vertebral Artery Testing

Symptoms of vertebral insufficiency include dizziness/vertigo, nausea/vomiting, inability to stand, blurred vision/diplopia, headache, facial parasthaesia/facial palsy/difficulty swallowing.

Following a thorough subjective assessment of the cervical spine, careful planning of the physical examination should be done together with consideration of any precautions and contraindications related to further examination of vertebral insufficiency.

International Framework for Examination of the Cervical Region for Potential of Vascular Pathologies of the Neck Prior to Musculoskeletal Intervention International IFOMPT Cervical Framework - Physical Examination

In addition to this the clinician should also reflect on their ability to perform certain tests and seek additional training if needed.

The following tests can be included for the assessment of vertebral artery insufficiency:

• Hautant test
• Cervical quadrant test
• Pre-manipulative position test

Canadian C-Spine Rules

The Canadian C-Spine Rule is a decision-making tool used to determine when radiography should be utilised in patients following trauma. The tool has a negative likelihood ratio of zero which means that if the test indicates that there is no need for radiographic investigation, then there is no need for an x-ray.

Functional Screening

Typically, a functional screen would include a chin tuck action, cervical flexion, extension and rotation, as well as shoulder movements.

Palpation

Palpation would include palpation of the relevant musculature of the cervical spine, as well as the spinous processes and facet joints.

Range of Motion

When assessing range of motion take note of symptoms associated with the movements. Generally, over-pressure is not applied when testing range of motion of the neck as the weight of the head is sufficient for testing.

Muscle Testing

A lack of endurance and ability to hold the neck in position due to weakness of the cervical deep neck flexors is related to neck pain. To assess the capability of the deep neck flexors, The Deep Cervical Flexion Test or Cranial Cervical Flexion Test, as well as neck flexor endurance testing can be performed.

Neurological Testing

A neurological screen will include testing of reflexes, spinal cord reflexes, dermatomal and myotomal testing. Also include a cranial nerve screen and upper limb tension tests.
