TAP OR PERCUSSION

TEST

​​• Test positioning

The client may sit or stand with the affected finger extended.

The therapist stands in front of the client.

​• Action

The therapist applies a firm tap to the end of the linger being tested.

As an alternative method to tapping the therapist may use a percussion hammer.

​

​• Positive finding

Pain at the site of injury indicates a fracture.

The vibration of tapping along the long axis of the bone will exaggerate pain at the fracture site.

​• Special considerations & comments

This test should not be performed if there is an obvious deformity.

The Tap or Percussion Test is influenced by the work of Dr. James Cyriax in orthopedic assessment, focusing on the evaluation of fractures and nerve compression injuries in the wrist and hand.
