My wife has had PD for 9 years with Postural Instability and Gait Disorder (PIG-D). No perceptible tremor, but problems with stiffness, gait, balance, falling, etc. She had PPN-target DBS early in 2011 in Toronto and that has led to a good deal of improvement. This has mostly been sustained since the surgery with periodic tweaking of the DBS settings.

A problem that still has to a great degree is an inability to sit up straight in a chair for any extended period of time. Sometimes if she is more fatigued the sliding can occur after even a few minutes sitting up. She ends up sliding down in the seat until she has slid to almost a reclining position and then will pull herself up only to have it happen again.

Has anyone on the list experienced this symptom? Are you aware of anything that can be done? Her doctor thought it had to do with core strength and might respond to exercise. I just don't know and have been unable to find anything on the internet that helps me understand the problem better or whether anything can help at all. Any ideas would be appreciated.

thanks in advance,

Howard
