when I got home from rehab it was the dead of winter and I had a hard time sleeping. I did not have alot of opportunity to exercise. I tied therabands to my bedroom door hinges and pulled on them every which way til I'd get tired. Long story short - exercise = sleep. FES doesn't count, the machine is doing the work.
Now that it's summer I push alot, fresh air and sunshine keep you awake (no napping) and use up energy... I realize it's harder in a power chair, but I believe exercise of any type (even Wii) helps sleep patterns, moods, depression, appetite, etc.
and only 2 starbucks a day! 8^]
