![]() Those treated with the Epley maneuver were six times more likely than those treated with the sham maneuver to test negative for BPPV in the follow-up Dix-Hallpike tests. The improvements were evident in the patients diagnosed with objective BPPV (vertigo and nystagmus) in the initial Dix-Hallpike test. They were also asked whether their vertigo had cleared up completely or not. ![]() At the follow-up visits, held a week, a month, and a year after treatment, the patients were administered the Dix-Hallpike test and asked to rate the severity of their vertigo on a scale of 1 to 10. The doctors responsible for assessing the patients did not know whether they had been treated with the Epley or the sham maneuver. All the patients were additionally prescribed betahistine, which is the main drug used to treat BPPV worldwide. The study was a clinical trial in which 134 patients with subjective and objective BPPV were randomly assigned to be treated with either the Epley maneuver or a sham procedure designed to mimic this maneuver. Our team designed a study to test whether family physicians could successfully use these two simple maneuvers to diagnose and treat BPPV after just a 2-hour training session. ![]() One of the reasons why the Dix-Hallpike and Epley maneuvers are not routinely used in these settings is that most studies to date have analyzed their use in specialized settings equipped with instruments to aid detection of nystagmus. Many patients with BPPV therefore are not properly diagnosed or treated. ![]() This repositioning technique is known as the Epley maneuver and is explained in the following video.Īlthough the Epley maneuver is very simple and highly effective (almost 100% of patients recover after undergoing the procedure up to 4 times), it is not routine practice in either primary healthcare or hospital emergency settings, which is where most of these patients are seen. The purpose of the maneuver is to reposition the dislodged calcium crystals in the semicircular canals. When nystagmus is not observed but the patient experiences vertigo, a diagnosis of subjective BPPV is made.īPPV can also be treated with a very simple physical maneuver that takes just 2 minutes and can be also by performed by family physicians. These movements explain why the patient feels that everything around him or her is spinning. This maneuver is called the Dix-Hallpike test and is shown in the following video.Ī diagnosis of typical or objective BPPV is made when the Dix-Hallpike test causes both vertigo and repeated, uncontrolled eye movements known as nystagmus. The posterior canal is the most frequently involved of the three canals.īPPV can be diagnosed using a simple physical maneuver that can be performed by a family physician without the need for specific equipment or for blood tests, X-rays, or other tests. Their sensitivity is altered by the displacement of calcium carbonate crystals normally attached to another part of the inner ear into the canals, triggering the symptoms of BPPV. These canals help control balance and contain a gelatinous substance known as endolymph. Although 50% to 70% of patients with BPPV improve within a month (with or without treatment), the condition can last for months or even years.īPPV is caused by a problem in the semicircular canals, which are three tiny tubes located in the inner ear. BPPV also has a considerable impact of quality of life, with two out of every three patients either stopping work or cutting back on hours. In addition, it is often accompanied by nausea and even vomiting.Ĭoncerned about this unpleasant and often frightening condition, patients tend to seek emergency care. The sensation is short-lived, but it returns as soon as the patient attempts to move again. ![]() The most common form of vertigo is posterior canal Benign Positional Paroxysmal Vertigo (BPPV), which can cause considerable anxiety as simple movements like turning over or getting out of bed can send the room spinning. Patients with vertigo feel as if the things around them or they themselves are spinning. Dizziness is the main symptom described in up to 5% of all outpatient consultations and the most common cause is vertigo. Patients who experience vertigo, which is typically described as a dizzy feeling, often seek emergency care at their local hospital or primary healthcare center. ![]()
