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.
