Enjoy Fun and Engaging Rehab Games at Home with Gemgem 400! ■ Who is it for? Our game is designed for individuals with limited movement on one side of the body or those who need fine motor rehabilitation. ■ Why “400”? Because performing 400 voluntary movements a day helps activate neuroplasticity in the brain, encouraging the formation of new neural pathways. ■ How effective is it? The key is quantity and autonomy! In other words, encouraging people to move more, on their own, is what really matters. In fact, both caregivers and developers were amazed at the changes experienced by users who consistently played GemGem 400. ■ What kinds of games are included? Jump, run, pop! We offer a variety of adventures that everyone can enjoy — with new content being added regularly. With the valuable feedback of caregivers, our service continues to improve every day. ■ Our goals are to: 1. Grow with joy through gaming 2. Build self-confidence 3.
