My mother is 82 years old and suffers from Parkinson's disease, resulting in her head drooping, Her doctor told her to get a neck brace to straighten out her neck and lift her head. We went to Walgreen's to try one on. Two and three inch ones were available. She tried on the two inch version. I told her we'd find one online. As soon as we got home, I found the Sammon's Preston two inch version. I ordered it and it arrived in a few days. She tried it on and was happy she selected the two inch brace. Last night, she told me it helps.
