I can do this test fine with my eyes open and pretty good on a flat surface, but on an incline, it can be pretty tough. However, my husband has a hard time with this one so I suspect somewhere down the road after many years of not wearing ear protection and his constant battle with tinnitus, he could have a slight balance problem himself. I practice this walk every evening. Lots of times I rely on my dogs to make sure all goes well.....don't trust them especially the 14 month old....
