The American Heart Association held the 2010 International Stroke Conference in San Antonio, Texas, February 24 - 26, 2010. The results of a study led by Gustavo Saposnik, MD and conducted at St. Michael's Hospital in Toronto were presented. This poster presentation explained the objective of this study as " to evaluate feasibility, safety, and efficacy of VR using Nintendo Wii gaming technology on motor function during stroke rehab." Readers may view the abstract of this poster beginning on page 3 of this link.
The outcome of this research is detailed in the chart accompanying the abstract found at that link.
Several news writers have summarized the results. In the Bloomberg Businessweek summary, Dr. Saposnik is quoted as saying, "Basically, we found that Wii therapy produced a 30 percent better improvement than recreational therapy in the time it took for the Wii patients to execute a task, and in how well they were able to execute a task."
In this study, the group assigned to recreational therapy preformed activities such as playing with cards and manipulating blocks in the game 'JENGA'. The intervention group participated in Wii activities including Wii Sports tennis and Wii Cooking Mama tasks.
Those participants in the intervention group demonstrated that "VR using Wii is a novel, safe and feasible strategy to facilitate motor function after sroke."
