Here is a wearable device that relies on music to help you during your rehab. MusicGlove is an FDA approved music-based rehabilitation device that uses music and gaming to make therapy fun. The device has a glove with sensors to track the user’s hand movements and relies on therapy-based games to motivate the user to make intensive and functional movements that can lead to improvements in hand function.
The device senses when you make different grips, so you can play games and make your hand function better. It gives you direct feedback on your performance and motivates you to keep going. There is a lot to like here. You can get started with MusicGlove for $99 a month.
