Nausea/dizziness caused by orthoses?

Hi everyone,

Was wondering if anyone can shed some light on a patient Im currently treating. She presented with bilateral painful HAV. She's 30 and in good health. No relevant medical history. As well as a stretching programme she was issued a pair of cad cam orthoses. She has been wearing them for 4 weeks and is experiencing acute nausea and dizziness when she wears them. These symptoms take aprox 1 hour to subside after removing the insoles.

Could this be an inner ear problem? All suggestions are most welcome.

Thanks

 

Hi,
An inner ear infection or a viral infection may be the cause. Has the patient a history of vertigo? If she had the bending down to insert and remove her orthoses would cause her to experience those type of symptoms. I would suggest that it is unlikely that her symptoms are the result of her foot orthotics. I don't know of any research in this area. Get her to vist her M.D for an assessment. He may prescribe Serc.
Hope this helps

 

Hi Clover

Sounds like Reverse Rothbarts effect!!!!!!!

Thanks Conmerchant,

Ive never heard of this before. From what I can gather, this is an insoles developed by professor Rothbart issued to improve the proprioception therefore improving posture. I cant find any info on this or any other device causing dizziness or nausua. Can you shed any more light on this, including how to procede with the patient. Im at a loss!

Me thinks Cornmerchant was being facetious. Try this: give your patient some flat 2-3mm eva insoles and get her to put them in and out of her shoes as she would the CAD/ CAM devices. This will at least expose whether it is the bending down that is causing the problem as foot soldier suggested. If this does not reproduce her symptoms, then you know that it is something specific about the devices, though I could not tell you what that could be. I have experienced this with a patient once before. The patient in question was somewhat nervous and excessively cautious in habituating to the devices- she took ages to get up to a normal daily wear pattern, but is ok now as far as I know. To be honest, I just thought that particular patient was a bit "out there", but perhaps there is something in reflexology.......

 

Apologies Clover, just being very tongue in cheek, no offence intended.

Simon offers very good advice.

Hi Clover,
no research only personal experience (which is of very limited value).

Have you looked at her standing on 1 foot with eyes open and eyes shut as a test for proprioception? If this is weak, balance exercises may improve her symptoms.

I experienced extreme motion sickness when trying on the rocker style shoes and the negative heel shoes available. I attributed my symptoms to my poor proprioception / balance.
