I want to share with you a question both of the patients asked me during our private sessions.
Many healthcare providers who rely solely on the common literature related to BPPV will tell the patient that if there is no observable nystagmus, then they do not have BPPV. If the patient gets symptoms during the BPPV test, they often explain to the patient that they are experiencing symptoms caused by a “conditioned response.”
Years ago, when I attended the first offering of the Advanced Vestibular Rehabilitation course offered by the Neurological Specialty Section of the American Physical Therapy Association, I learned for the first time about “symptomatic BPPV.”
The recommendation at that point is to perform the appropriate treatment for BPPV crystals in the canal that is being tested, and then see if that improves their symptoms.
For both of the patients I saw today, they did not have any eye movement in the BPPV test position but they had uncomfortable symptoms during the BPPV test and they had a history of complaints consistent with BPPV.
So I assessed them as having “symptomatic BPPV.”
When we did the treatment for BPPV crystals in the specific canal that I was testing for, their symptoms resolved to zero.
Symptoms caused by a conditioned response will only improve over a matter of weeks with repeated exposure to the testing position through exercises that desensitize the brain to its conditioned response.
Identifying and treating “symptomatic BPPV” is absolutely critical to optimal outcomes because head movements while BPPV crystals are still loose only cause agony for the patient, but head movement after BPPV crystals have been treated or ruled out completely is therapeutic in order to eliminate any remaining motion sensitivity or “conditioned response.”
