Stressed Grip Test for tennis elbow, golfer's elbow (epicondylitis, epicondylosis)

Be sure to ask about how it felt after each repetition, and if they had pain, where the pain was located.
Test Procedure:
- Take bilateral grip measurements in standard position
- Re-take bilateral measurements in stressed position:
- Tennis elbow-shoulder flexed to 90° with elbow extended, and forearm pronated
- Golfer’s elbow-shoulder flexed to 90° with elbow extended, and forearm supinated
- Therapist should not support the weight of the dynamometer; use hydraulic dynamometer
- Dial of the dynamometer should be by the client’s thumb in all positions
Positive results:
- More pain and less strength in stressed position vs. standard position. (Weakness and pain in standard grip position is a sign of more severe tennis/golfer’s elbow. Weakness and pain only in stressed grip position is a sign of mild-moderate tennis/golfer’s elbow.)
Negative Results:
- No weakness, no pain in stressed position; pain in extensor muscle bellies indicates Radial tunnel
Implications of positive test result:
- Tennis or golfer’s elbow (depending on which position)
