The Xtensor Rehab Glove

For people that experience arm pain due to repetitive tasks such as typing, the Xtensor glove may help relieve it with a bit of exercise. The product focuses on the muscles that rarely get any attention. Most people use their hands and fingers by squeezing and pushing, in other words, flexion gets all the work. Hence extension is rarely exercised, and that is what the company believes needs to be improved upon. The Xtensor glove provides that tension and may help folks train their pain away. Hopefully the company is right. Can anyone let us know about their experience with this device?
