Paxino's test

Purpose

To detect the presence of acromioclavicular joint pain.[1]

Technique[1]

  • With the patient sitting and the symptomatic arm by the side, the examiner's thumb is placed under the posterolateral aspect of the acromion and the index and middle fingers of the same (or contralateral) hand are placed superior to the mid-clavicle
  • The examiner provides pressure to the acromion in an anterosuperior direction with the thumb, while also applying pressure an inferior direction to the mid-clavicle with the index and middle fingers
  • If pain is elicited or increased in the region of the acromioclavicular joint, the test is considered positive
