Muscles with their tendons run from the hand via the wrist to the elbow - 5 muscles on each side of the elbow.
The purpose of these muscles is to enable the fingers, the metacarpus, the wrist, but also the forearm and the elbow joint to perform many different movements and functions.
Many people experience pain, inflammation, tears in the tendon insertions and overloading at or in the area of the elbow, resulting in epicondylitis (tennis elbow, golfer's elbow, mouse elbow)
