Have you ever been dizzy?
Benign Paroxysmal Positional Vertigo (BPPV) is a common cause of dizziness and accounts for 20% of all dizziness symptoms. As BPPV appears to be related to bone density, incidence increases with age and accounts for 50% of dizziness complaints in those over 60 years of age. BPPV is also the most common disorder of the peripheral vestibular system (the sensory system in our inner ear which contributes to balance). Primary complaints of BPPV are poor balance and vertigo (sensation of spinning), as well as lightheadedness, difficulty walking, nausea, or even visual changes which are made worse with activities such as rolling bed, reaching for an object on the floor or overhead or washing your hair. Treatment for BPPV can be quite effective in a relatively short amount of time (a few visits). Studies have reported an efficacy between 70-95% resolution for the maneuvers used to treat BPPV. Depending on the location and type of dysfunction, therapists utilize a series of positions to restore more normal function of the vestibular organ in your ear. While these positions often will provoke dizziness symptoms, they typically lead to considerable symptom relief.
Physical therapy is also appropriate for symptoms of dizziness or unsteadiness that are not described as vertigo. Multiple systems in our body are responsible for balance, coordination and effective function. In addition to your inner ear, your visual system as well as the joint receptors and sensation in your legs and feet all must analyze information harmoniously to maintain your balance. Some studies even suggest that the cervical spine plays a role in our nervous system’s ability to stabilize our balance. Dysfunctions to any of these systems (inner ear, eye, sensation, cervical spine, etc.) potentially could be related to an altered state of balance. If you, or someone you know, complains of dizziness or changes in balance/stability, contact your physician or physical therapist and see if you are appropriate for care.
