Here’s a mouse that rests on your table, but it doesn’t function as a pointer, rather, it functions as an Electrical Muscle Stimulator. The Muscle Mouse from Thanko is a regular USB optical mouse that attaches to a connector where a wired set of EMS (Electrical Muscle Stimulator) pads can be plugged in. Whenever your vital muscles are stressed, you could immediately attach the pads to your sore body parts and get instant relief through the special side buttons on the mouse which controls the stimulation levels.
If you’re bit of a medical freak, you should know that the EMS is also known as neuromuscular electrical stimulation (NMES) or electromyostimulation and it can be used either for training or as a therapeutic tool. Work with simultaneous massage should be fun! Just make sure you have a label for both your mouses.
