To perform Cozen's test, the therapist stabilizes the patient's elbow in 90 degrees of flexion with one hand while palpating over the lateral epicondyle.

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]

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]

Sensitivity and specificity has not yet been determined.
