Eccentric shoulder abduction trains the muscles that lift the arm sideways by making them control it on the way down. You get the arm overhead the easy way, by bending the elbow to bring the hand to your shoulder and pressing it straight up. Then you turn the arm so the little finger is on the outside and lower the straight arm slowly out to the side. The lowering is the exercise.

How to do the eccentric shoulder abduction

Stand with your feet hip width apart and your arms by your sides.
Bend the working elbow and bring the hand up to the front of your shoulder.
Push the hand straight up until the arm is straight above your head.
At the top, turn the arm so your palm faces forward and your little finger is on the outside edge, the edge that leads on the way down.
Lower the straight arm slowly out to the side and down to your hip, with the shoulder relaxed and your body upright. Then bend the elbow and press up again for the next one.

What you should feel

Work at the top and outside of the shoulder that builds as the arm comes down, most of all around shoulder height.

Common mistakes

Lifting the straight arm up the side instead of using the bent-elbow press to get overhead.
Letting the arm fall quickly through the middle of the range.
Shrugging, or leaning away from the arm, as it lowers.
Bending the elbow on the way down.

How often

Many programs use 2 to 3 sets of 8 to 12 lowerings, taking about 3 to 5 seconds over each one, once a day or a few days a week. Your physio will adjust this.

Stop and check with your physio if

A sharp pain or a painful catch at the top of the shoulder as the arm lowers.
Pain, pins and needles or numbness spreading down your arm or into your hand.
Pins and needles in your arm or hand that do not go away after you stop, or part of your arm or hand goes numb. Get medical advice the same day. If one side of your face or body suddenly goes numb or weak, or your speech becomes slurred or muddled, call emergency services, even if it goes away.
A sudden pop or tearing feeling in the shoulder that brings sharp pain, new weakness or trouble lifting the arm. Stop and contact your surgical team the same day, or get medical advice the same day if you have not had surgery.
The shoulder feels as if it has slipped out of place, looks a different shape or suddenly locks so you cannot move the arm, or your hand turns cold, pale or blue. Go to an emergency department straight away, without driving yourself, and do not try to put the shoulder back in yourself.

From the clinic

Pressing up with a bent elbow keeps the arm short and close to your head, so getting overhead takes far less effort than lifting a straight arm sideways. That lets you practice the controlled way down even while the lift itself is still hard. Take the lowering slowly, especially between head height and shoulder height, where the arm feels heaviest.

The voice guide says you can add some weight. If your physio agrees, a light dumbbell or a small water bottle of about 0.5 to 1 kg (1 to 2 lb) is a common way to start. The lateral raise works the lift as well as the lowering, and side lying dumbbell abduction loads the first part of the sideways lift. If you have high blood pressure, breathe steadily through every repetition and never hold your breath.

After shoulder surgery, including a rotator cuff repair, or after a shoulder fracture or dislocation, follow your surgeon's or physio's plan, and do only the movements and range they have cleared. Many plans allow only passive movement at first, where the arm is moved for you and its muscles stay relaxed. Taking the arm overhead and lowering it under its own control, with or without a weight, usually comes late in the plan after a cuff repair, so ask when it can start. If your shoulder has dislocated before or feels loose, check with your physio first, because overhead and out to the side with the arm turned out is where an unstable shoulder is most at risk.
