Mouse Elbow, Tennis Elbow

The development of tennis elbow can often be traced to the way of using the forearm muscles. The "overload" of tendons is commonly seen in someone who plays more tennis than usual, however a weekend of hedge clipping, excessive use of a screwdriver, hammer, computer mouse, or performance of other activities requiring constant squeezing or gripping can lead to this problem.

Your muscles control your hand and wrist movements and are attached to tendons that connect to only two small points of bone just above your elbow, one on the outer side, and the other on the inner side. The muscles connected to the outer side of your elbow are responsible for, straightening your fingers, bending your wrist upwards, and rolling your forearm into a palms-up position. The muscles connected to the inner side of your elbow are responsible for: bending your fingers, bending the wrist downwards and rolling your forearm into a palms-down position. Article
