At the last set of courses we ran, I asked GPs in the audience the following questions:How many feel they can confidently do Hallpike's manoeuvre?How many do it but are not quite sure what you are doing?How many just don't bother to do it at all because they are not sure what they are doing?
This was the subject of the BMJ's 'Easily Missed' series. Here I'll look from a GP perspective.As the review points out, it is easily missed because the main presenting symptom (syncope) is common, or because it is mis-diagnosed as epilepsy (the hypoperfusion of syncope may result in epileptic type movements).
This BMJ article looked at the causes of symmetrical peripheral neuropathy and how best to investigate it.
The symptoms include loss of sensation +/– burning pain of gradual onset. In a myelopathy the symptoms may be similar but reflexes should be preserved.
