Acromioclavicular Crossover (Cross Body Adduction) Test

Acromioclavicular Crossover Test

Acromioclavicular Crossover (Cross Body Adduction) Test – The Acromioclavicular Crossover test is used to detect acromioclavicular joint pathology. This test is also known as the cross-body adduction test and the horizontal adduction test. With the patient in the standing position and the elbow fully extended, support the shoulder and lift the arm to 90 degrees of shoulder flexion and then horizontally adduct it as far as possible. This maneuver compresses the acromioclavicular joint of the involved arm. Pain produced at the acromioclavicular joint constitutes a positive test indicating acromioclavicular joint pathology.

No Sound?  If you’re playing a video and the sound isn’t working, it may be because the sound is off. When playing a video from a desktop computer, you will see a series of vertical bars at the bottom right corner of the video. When the vertical bars are blue, it means the sound is on (see image 1 below). If the vertical bars are grey, it means the sound is off (see image 2). To turn on the sound of a video, click on each vertical grey bar until all the bars become blue. On smaller devices such as a tablet or a phone, simply increase the volume of the device to be able to hear a video.
