Recently there has been an upsurge in vestibular fraud -- both testing and treatment. This is an inflammatory topic, because it involves billing and assessment of competence. In discussions like this, one inevitably ends up implying that certain groups are incompetent and/or unethical, and this invitably ends up generating some rather unfriendly emails. Nevertheless, we diffidently offer our opinions here. The author (Dr. Hain), is an emeritus professor at Northwestern University in Chicago, and does vestibular testing and treatment routinely. He competes with some of the groups being discussed here. Commentary sent to the email address above is gladly accepted but it may be added to the content of this page.

Fraud

Vague and misleading advertisement for VRT.

Advertisement for "KoreBalance" therapy that Dr. Hain scanned in from his local (Chicago) paper.

OK - so how do we know that this is fraud ?

At the top, it asks "do you suffer from ... tinnitus ... " There is no device that is effective for tinnitus or Meniere's disease. While this advertisement does not directly indicate that this device is useful for these conditions -- the implication is strong. There is also an implication that this device can treat vertigo, motion sickness and faintness. It seems very implausible to us that training administered for 30 minutes twice/week can treat any of these conditions.

Second, lets look at what actually is being advertised -- Korebalance is a trademark of SportKat. Because this device is computerized, this device can be operated by someone with the same general expertise as the person who operates the cash register at your local convenience store. This advertisement does not mention any supervision by a physician. The lack of detail is disturbing.

Groups that advocate this procedure are generally stand-alone physical therapy groups without medical supervision. The author of this page feels that use of this device is usually a good indication that there will be unrealistic promises, unethical marketing practices, and inexpert care. See our page about how to find a VRT provider.

This advertisement does not pass the "would you send a family member to this group" test. I would not send someone from my family to a group that implied that they could treat tinnitus with a computerized balance testing machine.

1. Fraudulent vestibular rehabilitation treatment.

In the Sunday paper here in Chicago, we saw several advertisements for treatment of dizziness. We have put one of them above. This advertisement is extremely misleading - -the device being marketed (not even shown in the ad) is not proven to work and in fact, here it is suggested that it could be effective for conditions involving hearing (tinnitus) !

Here, the potential for abuse is gigantic as these practices have no mechanism to sort out the numerous causes of dizziness, and deceptive advertising is permitted.

 

Gyrostim
Gyrostim device.

The "Gyrostim".

A chiropractic practice in Chicago recently installed a "Gyrostim" device (see below). This is a carnival ride type gadget, advocated by Dr. Carrick (a chiropractor), for nearly any type of dizziness. This device is also advocated for treatment of MdDs, and a physical therapy practice in Asheville NC, installed a device as well.

We are not seeing places like Harvard or Mayo install these devices. We are seeing out of the way practices in North Carolina and chiropractors put these devices into service. This is disturbing.

Oddly enough, although groups are buying these devices, there is ZERO SCIENTIFIC EVIDENCE that the Gyrostim helps anyone. Let me repeat -- as of today (4/14/2018), there are NO SCIENTIFIC PAPERS IN PUBMED on the Gyrostim.

What we do have though are papers on "pitch while rotating", which is the core part of this device. Pitch while rotating is a very powerful source of motion sickness (Raphan et al, 1983; Raphan et al,1999).

We have heard that taking a "ride" on this device is very costly. This makes some sense as putting a carnival ride in your medical clinic must be costly as well. There are substantial risks here, both for the patient (might be a waste of time and money), and for the clinic (expensive gadget, will it be profitable, will people get hurt and sue clinic ?)

Overall: The Gyrostim is an unproven method of treatment. It may help people through habituation. Unproven things are not always fraud, but the context here is disturbing. This is also very much a "buyer beware" situation. Unless you have money to burn, and don't mind vomiting that much, we think best to avoid this device.

2. Cerebellar "treatment" of dizziness by Chiropracters.

Here we refer to individuals - -mainly chiropracters -- who advocate and bill for a mixture of valid anatomy/physiology with irrational and ineffective treatments. Chiropractors often generate notes that are "word salad" -- they produce notes that seem to be randomly generated mixtures of medical words, that have no meaning at all. This often results in outrageous statements:

Chiropractic word salad

The above is copied from a chiropractic note from a local practice in Illinois. Lets deconstruct this paragraph. First sentence -- vague and meaningless, also ungrammatical. Second sentence -- "Proto-onco gene" -- onco-gene has to do with cancer. What on earth is this doing in a note about an inner ear problem ? Third sentence -- "We need to restore plasticity ... ". This is strange -- one treats BPPV with a physical maneuver. Next sentence -- "coupled manipulation ...". This is nonsense. Last sentence -- "We also need to some ...". Not grammatical, but it is true that actitity might help. So -- Chiropractic word salad.

Another example of this is the site http://www.askdrjohnson.com/dizziness.php -- where a "chiropractic neurologist", "Dr. Johnson", makes some very unreasonable claims.

On this site, "Dr Johnson" indicates that cerebellar disorders can be detected by tests of coordination - -this is true. However, he leaves out a large amount of critical information -- as only a small fraction of dizziness conditions are caused by cerebellar disorders. This in nearly all situations -- this observation that cerebellar disorders can be diagnosed by specific clinical procedures --- is irrelevant to almost all dizziness.

Then, "Dr Johnson" goes on to indicate that the cerebellum can be treated by (and I quote -- italics added to make it clear what is being quoted)

"Treatment of the cerebellar dysfunction may include:

One or all of the procedures may be employed to restore the cerebellum to its normal function."

These statements (even if they were relevant and they are not) are either false or simply extremely misleading, as none of the procedures "Dr Johnson" advocates are legitimate methods of making a durable change to cerebellar function.

For those patients with dizziness who chose to spend their personal cash on these types of procedures -- we wish them well, but we think their money could be better spent. There is a latin phrase -- caveat emptor (buyer beware).

Our suggestion regarding dealing with Chiropractic vestibular treatment fraud.

Irrational vestibular treatments

There are also many instances where the individuals proposing the treatments could be well intentioned, but the treatment advocated obviously will never result into anything useful.  One wonders why such devices manage to flourish in spite of their lack of reasonableness. One interpretation is that "hope springs eternal", but another possibility is simply that these projects are being funded by government grants. See this page for more.
