Martha recently posted about how exercise can help stroke patients recover. A new virtual reality program that is undergoing clinical trials in the UK and in Canada helps the recovery process a little more.

A researcher at Portsmouth University in the UK created a treadmill that's linked to a virtual reality system. The system helps people recovering from strokes, traumatic falls, and those living with osteoarthritis to build up their endurance, increase their range of motion, and improve their gate.

The system displays scenes -- cityscapes, forest trails, mountains, etc. As the patient is walking on the treadmill, the scenery changes. The system gives them the motivation to walk -- and it also encourages them to virtually pick up objects which aids in balance. In addition, the motion of the scenery is adjusted so the patients walk faster and more smoothly, almost without realizing it.
