My daughter was in that study last summer for 10 weeks. For anyone considering it, you must have RSD in one limb/side only so that they can use the other side for comparison. They will do a lot of testing on you and they are very thorough. All of this is free to you so it is a wonderful opportunity for those with limited or no insurance.
The staff is very nice there as well. We were able to stay at the Marriott right down the street which took the per diem rate and included parking in it as well.
