Repetitive stress leads to tendon overload and micro tearing of the tendon. Over time and with continual stress the tendons can no longer repair the micro tears and degeneration and inflammation occur. Medial epicondylitis is associated with repetitive:

• Concentric Wrist Flexion
• Eccentric wrist flexion
• Pronation

It is common with pitches or golfers secondary to the valgus stressed placed on said activities. Professions such as electricians, plumbers, contractors, laborers are more prone to developing medial epicondylitis.


Tenderness over medial condyle and flexor/pronator muscles. Positive Medial epicondylitis test/golfers test, and elbow flexion test. ROM may or may not be decrease. Decrease grip and wrist flexion strength.

Differential diagnosis:

• C6-7 radiculopathy    
• Ulnar and medial nerve entrapment  
• Ulnar collateral nerve stability   
• ULTT 1, 2A and 3
• Valgus test
• Cervical screen
