Purpose[edit | edit source]
The purpose of Cozen's test (also known as the "resisted wrist extension test" or "resistive tennis elbow test") is to check for lateral epicondylalgia or "tennis elbow".
Patient Position[edit | edit source]
The patient should be seated, with the elbow extended forearm maximal pronation, wrist radially abducted, and hand in a fist.
Examiner Position[edit | edit source]
The therapist should stabilise elbow while palpating lateral epicondyle, other hand placed on the dorsum of the hand.
Technique[edit | edit source]
The patient is asked to move the wrist to dorsal flexion and the therapist provides resistance to this movement, in the position described above.[1] The test is positive if pain on the lateral epicondyle is elicited.

Helpful Tips[edit | edit source]
To reduce the likelihood of finding pathology at the origin of extensor digitorum, keep the patient’s fingers flexed during resisted wrist extension. During isometric wrist extension, the counter-force should be applied on the dorsoradial aspect of the fist to reduce involving extensor carpi ulnaris and thus obtaining a false-positive finding if there is pathology within this muscle/tendon.[2]
Evidence[edit | edit source]
A study that analyzed the diagnostic accuracy of provocative tests for lateral epicondylitis indicated that Cozen's test has a sensitivity of 84% and specificity of 0%,[3] indicating a high probability of detecting lateral epicondylitis in individuals who have the condition but a poor probability of determining the absence of disease in disease-free individuals.
