Years ago i attended a conference on treating chronic pain. A family practice doctor presented a session on non-pharmaceutical approaches to pain control. Exercising was high on the list of treatment modalities -- especially walking.
"But what about our patients who are wheelchair bound?" Questioned one of the doctors in the audience.
In response the speaker made an enthusiastic pitch for chair exercises.
Years later, I experienced for myself how effective chair exercising can be. Now something new: Yesterday the morning exercise here at Hill House included a session on chair tai chi. I was a bit sore later and slept quite well last night. I now am a believer in the effectiveness of chair tai chi.
