Impact is an activity tracking device that aims to help women who were once athletic, but have now suffered a leg or foot injury and are stuck on crutches.
When you have a leg or foot injury and are forced to use crutches, there is a tendency to use the crutches incorrectly or not use them at all. Many people experience armpit pain as well as muscle compensations as your activity levels drop lower than before.
Impact's function encourages proper usage of crutches by gently vibrating when you don't put your complete upper-body weight on the handle (this is the proper use of the crutch). This helps ease any pressure off of your armpits and eliminates soreness. There is also a distance tracking feature with the option to set distance goals for improvement. According to users, goal setting and distance tracking is the best motivation to keep using crutches.
