2. 2 FOREGROUND Question for Today Is early discharge of stroke patients followed by outpatient rehabilitation more efficient as compared to hospital care?

3. 3 FQ 2 Background Questions  Definition of stroke  Physical therapy, rehabilitation (in general)

4. 4 Background Questions Merck Manual of Diagnosis and Therapy  World widely used medical textbook  Publication is searchable http://www.merckmanuals.com Search  stroke +rehabilitation

5. 5 Stroke - definition  Stroke occurs when an artery to the brain becomes blocked or ruptures death of an area of brain tissue (cerebral infarction) and causing  Sudden symptoms: muscle weakness, paralysis, abnormal or lost sensation on one side of the body, difficulty speaking, confusion, problems with vision, dizziness, and loss of balance and coordination.

6. 6 Stroke - rehabilitation  Intensive rehabilitation can help many people overcome disabilities after a stroke  The exercises and training of rehabilitation encourage unaffected areas of the brain to learn to perform functions that were done by the damaged area.  Also, people are taught new ways to use muscles unaffected by the stroke to compensate for losses in function.  After discharge from the hospital, rehabilitation can be continued on an outpatient basis, in a nursing home, in a rehabilitation center, or at home.

7. 7 Answering Foreground Questions  Foreground questions can be more difficult to answer than background questions;  They require sources that synthesize a wide range of knowledge.
