Usage Everyone using a computer are using their arms and hands for something else than the nature intended. Typing on the keyboard and controlling the computer mouse can be straining on the small muscles in the underarm, and many people suffer from muscle pain. The EXPAIN Change Arm is a wearable device that enables the user to remove the cause of their pain. The device attaches to the underarm with an elastic strap. It measure and analyze your muscle activity and vibrates when it detects a muscle activity pattern that might lead to pain. Sustained muscle activity for more than 60 seconds triggers the vibration. The vibration is a signal to take a micro-break or change your arm position. When you take a micro-break, the muscle relaxes and can recover from static or long-term activity. After a while you will change your habit and regularly start to take more micro-breaks. This will remove the cause of the pain, and the pain will be reduced and eventually go away. The device can also be used as a tool in making your workstation more ergonomic and detecting what activities during the day that cause your pain. The device is for everyone with muscle-related pain in the underarm.
