New research has found that a low-intense exercise program can reduce depression symptoms and boost physical therapy results in recovering stroke patients.

Scientists in Canada followed 103 recovering stroke patients who were all receiving regular, standard treatment in the hospital. About half were also enrolled in an additional, experimental program for upper limb recovery called Graded Repetitive Arm Supplementary Program (GRASP). Patients in this program spent an extra 35 minutes four times a week doing non-intense arm exercises as part of rehabilitation activities, such as pouring water in a glass, buttoning up a shirt, or playing speed and accuracy games.

In addition to improving arm and hand movements, the GRASP patients also reported less depressive symptoms and greater change in their outlook than those in the control group.

"The power of physical activity to raise the spirits of recovering stroke patients is stronger than anyone suspected," said Heart and Stroke Foundation researcher Jocelyn Harris, Ph.D.

It is estimated that between 23 and 72 percent of stroke patients suffer from depressive symptoms after a stroke.

Researchers say their findings are important for planning for the needs of the baby boomer generation who are currently poised to enter the high stroke risk stage.
