I am not in the habit of endorsing products, and I have no relationship (financial or otherwise) with Jed-Med, but after performing more than 50,000 vestibular exams in the same exam chair, I gotta say, “This chair rocks!”
We find that the Jed-Med S-II chair is an excellent choice for ENG/VNG examinations, as the chair can be reclined quickly for positional testing, at a 30-degree angle for caloric testing, and elevated or lowered for better access to the patient for canalith repositioning (CRP). There is a removable head rest for performing the Dix-Hallpike test and CRP. It can be brought back quickly into the seated position from the reclined position for doing orthostatics (which requires a little bit of muscle).
This chair is problematic if one is attempting a barbecue roll for treatment of horizontal canal positional vertigo, and the Semont maneuver simply cannot be performed in the JedMed S-II chair. A standard examination table would be better suited for those tasks.
The only problem we have ever had involved a 400-pound patient. The weight caused a fracture of the metal plate connecting the chair to the pedestal. No one was injured and Jed-Med was very responsive. We sent them a picture of the cracked plate, they sent us a replacement with instructions of how it should be attached. That was five years ago, and we have had no additional problems.
