HYPEREXTENSION

TEST

​• Test positioning

​The client sits or stands with the elbow fully extended and the forearm supinated.

The therapist grasps the distal humerus at the areas of the medial and lateral epicondyles with one hand, while the other hand grasps the distal forearm of the client.

​• Action

The therapist passively extends the elbow until no further motion is available.

​• Positive finding

​Elbow extension beyond 0 degrees is considered hyperextension.

A positive finding of hyperextension may be attributed to a torn or stretched anterior capsule of the elbow.

​• Special considerations & comments

​Assessing this motion should always be done bilaterally to determine the normal range of motion for the individual client. 

Hyperextension findings may vary depending on the type of end feel noted.

The Hyperextension Test is influenced by the work of Dr. James Cyriax in orthopedic assessment and Dr. Don O'Donoghue, whose contributions to understanding joint hypermobility and instability have been crucial.
