Objective: Exercise is an effective intervention for depressed individuals, but adherence is often poor. Exergaming may be useful for stimulating motivation and adherence with physical activity. This study piloted the use of the Nintendo(®) "Wii™ Fit" (Nintendo of America, Inc., Redwood City, CA) as part of cognitive behavioral treatment (CBT) for soldiers.
Subjects and methods: Male soldiers with depression (N=3) were treated in a military treatment facility using a case-controlled research design. Patients were loaned a "Wii Fit" during five of 10 CBT treatment sessions and asked to exercise at least 20 minutes/day.
Results: Rates of compliance and minutes of exercise were no different during the periods with and without the "Wii Fit." All three patients reported a reduction in depression severity following treatment.
Conclusions: This study provides important lessons learned for future studies of exergaming for patients with depression. Exergaming software is typically not designed for clinical populations, and certain characteristics of the game may decrease the likelihood of use. Researchers should consider the characteristics of various available exergaming platforms and select one that represents a clinical and cultural fit for their patient population.
