People who have suffered debilitating strokes often have to cope with impaired muscles that do not work properly. Even a simple act such as standing up from a chair and walking a few steps can become extremely difficult. Stroke victims often have to rely on wheelchairs, sticks, walking frames and other "orthotic" devices to move about.

Can electricity cause
cancer In a society that literally runs on electric power, the very idea seems
preposterous. But for more than a decade, a growing band of scientists and

qualified support from the U. S. Environmental Protection Agency. In the
executive summary of a new scientific review, released in draft form

{{B}}Youth Emancipation in
Spain{{/B}} The Spanish Government is so worried about the number
