Following my injury, I could not even do the first opening move of the T'ai Chi form, even from my wheelchair. I have made little gains, gradually leading to larger gains in developmental progress. Many inspirational teachings, teachers, and therapists continue to help me along the way. I would like to spark their enthusiasm to persevere, make daily progress, practice with patience, even developing patience with impatience. These qualities are invaluable, regardless of one's physical condition, and T'ai Chi is but one way to learn them.
Physical challenge covers a wide range of situations.
Focus on what you can do, even if there is no physical movement possible. Just the act of visualization has many benefits. Slow, relaxed movement like T'ai Chi engages a different part of the nervous system than more vigorous exercise does. Many injuries, traumas, or illnesses cause blocks that can thus be worked out and relieved. This point is related to the body's center of gravity.
