Karena is called upon by Dr. Primas to treat patients with these inner ear problems. Treatments are done at the office of ActiveCare Physical Therapy, but most oftentimes in home visits are required secondary to the severity of symptoms. Medication is typically given by Dr. Primas for motion sickness during his visit. Karena then applies a physical maneuver which is required to reduce the vertigo (to return the crystals into the appropriate position). The maneuvers are specific to the structure in the inner ear most affected. The two therapies work in conjunction with one another and typically reduce the symptoms quickly and most efficiently. Karena has advanced training in Vestibular Rehabilitation.
