Towards evidence based emergency medicine: Best BETs from the Manchester Royal Infirmary. BET 2: Leg crossing to prevent syncope.

A short cut review was carried out to establish whether leg crossing prevents transient loss of consciousness in patients known to have orthostatic hypotension. 9 papers presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that leg crossing can help reduce the incidence of transient loss of consciousness in patients with orthostatic hypotension.
