Also known as lateral epicondylalgia → irritations of tendon of extensor carpi radialis brevis muscle that attaches to the outside of the elbow
Due to overuse of finger and wrist extensors with grip intensive activities such as gardening, typing, cooking and tennis
Occurs during tennis when you follow through with the racquet, controlling the wrist and slowing it down.
Wrist extensors are slowing the wrist as it bends putting tension on the upper forearm tendons
Occurs when the tension is used with high force or at high volume or from repetitive overuse if the finger extensors are constantly opening the hand
Signs/symptoms:
Pain along the outside of the elbow that increases with finger and wrist extension (bending wrist toward arm)
Dull/achy, may be sharp
Weakness in hand and forearm
Typing on a keyboard or opening, closing or squeezing hands
