Cervical Manipulation Request with Transient Neurological Symptoms
A 41-year-old woman presents 3 weeks after a rear-end motor vehicle collision with neck pain and headache. She asks for 'the neck manipulation my friend had.' She describes two episodes of transient dizziness, diplopia, and nausea when looking up while reversing her car. She has a history of migraine but no other medical conditions. Examination shows restricted cervical rotation, paraspinal tenderness, and no neurological deficit. Blood pressure is 128/82 mmHg. She is otherwise well and has no gait disturbance. She works as a primary school teacher and is anxious about missing work. The referring general practitioner has written 'please manipulate cervical spine' on the referral.
1. Identify the red flags and explain whether high-velocity cervical manipulation is appropriate.

The red flags are transient dizziness, diplopia, and nausea provoked by cervical extension and rotation. These suggest possible vertebral artery insufficiency or posterior circulation ischaemia, even though symptoms resolved. Migraine may lower the threshold for concern but does not explain diplopia.
High-velocity cervical manipulation is not appropriate while these symptoms are unexplained. The presence of diplopia and nausea with neck movement is a warning sign for vertebrobasilar insufficiency or dissection. Pre-manipulation positional tests have poor predictive value and cannot rule this out. The GP's request does not override the clinical finding. Refer for urgent medical assessment before any cervical manual therapy.
2. Describe the informed consent discussion, including what you would document.

Explain that her symptoms raise concern about blood flow to the brain and that manipulation could be dangerous. State clearly that you will not perform high-velocity manipulation today. Discuss the uncertainty, the need for medical review, and alternative options.
Document:
- The specific symptoms, their duration, and provoking movements.
- Why manipulation was declined and that the GP was informed.
- The referral made and urgency.
- That the patient understood and agreed to the alternative plan.
- If she insists on manipulation, record the risks explained and offer a second opinion. Do not proceed merely because the patient or referrer requests it.
3. Outline an alternative, evidence-based management plan and when you would refer.

Offer gentle cervical mobilization within a pain-free range, soft-tissue treatment, postural education, and a graded neck exercise programme. Avoid end-range rotation and extension. Reassure her that most whiplash-associated disorders improve, and provide work advice.
Refer urgently to emergency or neurology if she develops new neurological signs, severe headache, visual loss, slurred speech, or gait disturbance. Refer to her GP for vascular assessment given the transient diplopia. Reassess before progressing to any rotational manual therapy, and only after medical clearance.
