number one i think uh in general we like having patients with parkinson's have exposure to physical therapy one-on-one periodically and i think the idea there is what you've said for a couple reasons obviously one you want to make sure you're challenging yourself you want to make sure you're not hurting yourself but also you really are gaining kind of a tool set and feedback on what you need to be working on and it is as i said you you know getting the feedback to be accurate and problem solved to do it again better right and so you know you definitely want to progress and get better number one um and two you can kind of use those tool sets to you know apply now to a class which is so you're doing you know what your class but you kind of know what you need to be working on so i kind of like that that combination
