Rotator Cuff Exercises and When to See a Physio

Shoulder pain when you reach for a high shelf, put on a jacket or roll onto your side at night is often linked to the rotator cuff. These four small muscles do a lot of work, and they are a common source of shoulder pain in adults. This guide explains what the rotator cuff does, the problems that affect it, some gentle exercises to try, and the signs it is time to see a physio.

What Is the Rotator Cuff?

The rotator cuff is a group of four muscles (supraspinatus, infraspinatus, teres minor and subscapularis) that start on the shoulder blade and attach by tendons to the top of the upper arm bone. Together they hold the ball of the shoulder centred in its shallow socket while larger muscles move the arm.

Because the shoulder moves through such a wide range, the rotator cuff is working almost every time you reach, lift, push or throw. That constant demand is one reason rotator cuff pain is so common, especially in people over 40 and in jobs or sports that involve lifting or overhead work.

Common Rotator Cuff Problems

Rotator cuff pain is usually felt at the front or side of the shoulder and can spread down the outer upper arm. It is often worse when lifting the arm out to the side or overhead, and when lying on that shoulder. These are the most common causes.

Rotator Cuff Tendinopathy

Tendinopathy means the tendon has become painful and less able to handle load, usually after a change in activity such as a new job, a burst of renovation work or more time at the gym. It tends to build gradually. Strengthening is usually a central part of managing it.

Partial and Full Thickness Tears

Rotator cuff tears can happen suddenly, for example after a fall onto an outstretched arm, or develop slowly with age-related wear. Many people with tears on a scan have little or no pain, and many tears are managed with exercise. A large tear after an injury, especially with sudden weakness, may need a surgical opinion.

Pain Under the Shoulder Arch

Pain felt when lifting the arm between shoulder and head height is sometimes called impingement or subacromial pain. The rotator cuff tendons and bursa sit under a bony arch at the top of the shoulder, and they can become irritated with repeated overhead work. Improving rotator cuff and shoulder blade strength is a common focus of treatment.

Gentle Rotator Cuff Exercises to Try

The exercises below are commonly used early in rotator cuff rehab. They are general examples only, not a personalised program. If you have had shoulder surgery or a recent shoulder injury, follow the program your surgeon or physio gives you instead, as some movements need to wait while the shoulder heals. Start gently, move slowly, and stop any exercise that causes sharp or worsening pain.

Pendulum Swings

Lean forward and rest your good hand on a table, letting the sore arm hang down. Gently sway your body so the arm swings in small circles or forwards and back, keeping the shoulder muscles relaxed. This is often used to ease stiffness in the early stages.

Isometric External Rotation Holds

Stand side-on to a wall with your elbow bent to 90 degrees and tucked into your side. Press the back of your wrist gently into the wall, as if rotating your forearm outwards, without the arm moving. Hold for 20 to 45 seconds and repeat a few times.

Side-Lying External Rotation

Lie on your good side with a rolled towel between your elbow and your ribs. Keeping the elbow bent to 90 degrees and against the towel, slowly rotate your forearm up towards the ceiling, then lower it. Start with no weight and add a light weight only when this feels easy.

Resistance Band Rows

Loop a light resistance band around a door handle at chest height. Hold the ends, stand tall and draw your elbows back while gently squeezing your shoulder blades together, then return slowly. This works the muscles that support the shoulder blade, which helps the rotator cuff do its job.

How to Exercise Your Shoulder Safely

Some discomfort during rotator cuff exercises can be acceptable, but how your shoulder responds over the next day matters most. A few simple guidelines help you stay on the right side of that line.

• Keep pain during exercise mild, around 3 out of 10 or less, and settling soon after you finish
• If pain is worse the next morning, reduce the number of repetitions or the resistance next time
• Move slowly and with control, avoiding jerky or swinging movements
• Do not push through sharp, catching or pins-and-needles pain
• Increase difficulty gradually, changing only one thing at a time, such as resistance or repetitions
• Be consistent: little and often usually works better than one big session

When to See a Physio for Shoulder Pain

Mild shoulder aches often ease within a week or two. It is a good idea to see a physio when pain hangs around, keeps coming back, or limits what you can do. Signs it is worth booking an assessment include:

• Pain lasting more than two weeks, or getting worse despite rest and gentle exercise
• Pain that wakes you at night or stops you lying on that side
• Difficulty lifting your arm, reaching behind your back or doing up a seatbelt
• Shoulder pain affecting your work, especially in a physical or overhead job
• Recurring shoulder pain whenever you return to the gym or sport

If shoulder pain comes with chest pain, shortness of breath, sweating or nausea, call 000 straight away. Go to your nearest emergency department if the shoulder looks out of place, if pain follows a fall or accident and you cannot lift the arm, or if pain comes with a fever or you feel very unwell. See your GP promptly if shoulder pain comes with numbness, pins and needles or weakness down the arm.

How Physio Treats Rotator Cuff Problems

Your physio will ask how the pain started and what aggravates it, then assess how your shoulder moves, its strength and specific tests to narrow down the cause. They may also look at your neck and shoulder blade. This musculoskeletal care for shoulders starts with understanding what is driving your pain.

Treatment usually centres on a progressive exercise program, adjusted to your shoulder's response, combined with advice on modifying aggravating tasks for a while. Hands-on treatment or dry needling may be used, with the aim of making movement more comfortable. Your physio explains the possible side effects first, such as soreness or bruising after dry needling, and only uses a technique if you agree to it. Your physio will also let you know if a scan or a GP or surgical review would help.

Shoulder injuries are common in physical jobs. If yours happened at work, work injury physiotherapy may be covered once a WorkSafe Victoria claim is accepted.

Getting Help for Shoulder Pain

If shoulder pain is limiting your work, sleep or sport, a physio assessment can help you understand what is going on and whether a rehab plan may suit you. It can help to read about booking a first physio visit before you come in. Northern Physio's Epping clinic sees people from across Melbourne's north, including Lalor, Wollert, Mill Park, South Morang and Craigieburn.
