No healthcare intervention is zero risk. The useful question is whether an option is appropriate for the individual and whether the expected benefit justifies the relevant risks and alternatives.
Some people experience temporary soreness, stiffness, tiredness or a short-lived increase in symptoms after manual treatment. These effects are usually mild, but you should report anything that concerns you.
Serious complications reported after spinal manipulation are uncommon, but they can be severe. The true frequency of some events is difficult to establish. Safety should never be presented as guaranteed or risk-free.
Cervical artery dissection can cause stroke and may initially present with head or neck pain. Research has not resolved every question about causation. A clinician must consider the history, symptoms, examination, alternatives and the person’s preferences before recommending a neck technique.
Risk management includes a careful history, examination, recognition of warning signs, referral when indicated, explanation of material risks and alternatives, and adapting or avoiding a technique. Lower-force or non-manipulative options may be discussed where appropriate.
Call 999 for possible stroke symptoms such as facial droop, speech difficulty, sudden weakness or numbness, collapse, severe dizziness or a sudden severe headache. Use NHS 111 if you need urgent advice and are unsure what to do.
