For elders hand rehabilitation, an interesting game would enhance effectiveness through interacting with both muscles and brain. According to Physiopedia, elders above the ages of fifty would have chances of suffering from deteriorating hand movement. Thus, by training the muscles and nerves of our hands, such symptoms could be ameliorated. Combining fun games with therapy could benefit the relationship between families and also improve physical health.
