I have had a very good experience working with Feldenkrais, however, the quality of the instructors varies which is quite normal. Try to find a teacher that is familiar with PD. I found that my awareness of my body in space, how it moves and particularly how to move with less effort and how to walk with less effort to be very helpful. My gait improved and my posture improved dramatically. A simple excercise combining a pelvic tilt and neck movements which can be done on a chair or on the floor immediately straight- ens out my spine. I have also found yoga to be extremely helpful as well as very reasonable. Also, if it is difficult to get out, these practitioners will come to your home and if you can get a small group together you can all benefit from the instruction and share the cost. I have found these therapies to be a great bang for the buck.
