To evaluate the improvement of vertigo in patients diagnosed with BPPV in the ED.The objectives to be determined in this study are as follows: conventional therapy in ED patients who present with vertigo. The purpose of this study is to compare the efficacy of vestibular rehabilitation vs. Several reviews of the management of vertigo have shown that no medication in current use has well established curative or prophylactic value or is suitable for long-term treatment. This method of treatment has had questionable success. It is presently common for ED physicians to treat these patients mainly with benzodiazepines, antihistamines, and anticholinergic medications, especially if the history and physical is consistent with BPPV. Common practice by ED physicians is to rule out serious medical causes for their symptoms. It was first described by Barany in 1921, and later described in more detail by Dix and Hallpike in 1952. Condition or diseaseĭrug: Meclizine Other: Epley Maneuver Drug: Lorazepam Drug: Diphenhydramine Drug: Ondansetronīenign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, accounting for 20% of all vertigo cases. The hypothesis of this study is that vestibular rehabilitation will allow for resolution of symptoms without the use of conventional medication therapy in the acute management of BPPV in the emergency department patient. All patients enrolled into this study are emergency department patients who have been diagnosed with BPPV via a positive Dix-Hallpike Maneuver. Patients will be randomized to receive the more common conventional medication therapy versus the canalith repositioning technique.
It is the purpose of this study to evaluate and examine two methods of treatment. The importance of early diagnosis and treatment can lead to a much improved quality of life for patients afflicted by this ailment. Why Should I Register and Submit Results?īenign Paroxysmal Positional Vertigo (BPPV) is a common complaint of emergency department patients.The dizziness of BPPV can make you unsteady, which may put you at greater risk of falling. ComplicationsĪlthough BPPV is uncomfortable, it rarely causes complications. A head injury or any other disorder of the balance organs of your ear may make you more susceptible to BPPV. BPPV is also more common in women than in men. Risk factorsīenign paroxysmal positional vertigo occurs most often in people age 50 and older, but can occur at any age. This causes the semicircular canal to become sensitive to head position changes it would normally not respond to, which is what makes you feel dizzy.
When they become dislodged, they can move into one of the semicircular canals - especially while you're lying down. These otolith organs contain crystals that make you sensitive to gravity.įor many reasons, these crystals can become dislodged. Other structures (otolith organs) in your ear monitor your head's movements - up and down, right and left, back and forth - and your head's position related to gravity. It includes three loop-shaped structures (semicircular canals) that contain fluid and fine, hairlike sensors that monitor your head's rotation. Inside your ear is a tiny organ called the vestibular labyrinth. BPPV also has been associated with migraines. Less common causes of BPPV include disorders that damage your inner ear or, rarely, damage that occurs during ear surgery or long periods positioned on your back, such as in a dentist chair. When there is a known cause, BPPV is often associated with a minor to severe blow to your head. These sensory hair cells help you keep your eyes focused on a target when your head is in motion. Semicircular canals and otolith organs - called the utricle and saccule - in your inner ear contain fluid and fine, hairlike sensors. The signs and symptoms listed above may signal a more serious problem. Seek emergency careĪlthough it's uncommon for dizziness to signal a serious illness, see your doctor immediately if you experience dizziness or vertigo along with any of the following:
Generally, see your doctor if you experience any recurrent, sudden, severe, or prolonged and unexplained dizziness or vertigo. Some people also feel out of balance when standing or walking.Ībnormal rhythmic eye movements usually accompany the symptoms of benign paroxysmal positional vertigo. Episodes of BPPV can disappear for some time and then recur.Īctivities that bring about the signs and symptoms of BPPV can vary from person to person, but are almost always brought on by a change in head position. The signs and symptoms of BPPV can come and go and commonly last less than one minute. A sense that you or your surroundings are spinning or moving (vertigo).The signs and symptoms of benign paroxysmal positional vertigo (BPPV) may include:
