Rotator Cuff Tendinopathy & Partial Tears

Overview

The rotator cuff is a group of four muscles whose tendons wrap around the top of the upper arm bone and hold the ball of the shoulder joint centred in its socket. They lift the arm, rotate it, and keep it stable while the bigger muscles do heavy work.

Tendinopathy means the tendon has become painful and less able to cope with load, usually because demands on it have outpaced its capacity to recover. Over time the tendon structure can change and small, partial tears may appear. Partial tears are extremely common on scans — many people over 40 have them without any symptoms — so a tear on an image does not automatically mean it is the cause of your pain.

The classic sign is a "painful arc": lifting the arm out to the side is fine at first, hurts through the middle of the range (roughly 60–120 degrees), then eases again near the top. Reaching into the back seat of a car, putting on a coat and lying on the shoulder at night are typical triggers.

Most rotator cuff pain responds well to a structured loading programme, though it can take a few months of consistent work.

Causes and risk factors

• Sudden increases in gym volume, especially overhead pressing and bench press
• Overhead sports (swimming, tennis, badminton, climbing) and overhead jobs (painting, hairdressing)
• Age over 40, as tendons become less tolerant of load
• Poor shoulder blade control or a rounded, forward-head posture
• Weak rotator cuff relative to the chest and upper trapezius
• A fall onto an outstretched arm, which can cause a partial tear
• Smoking and diabetes, which affect tendon health

How we may be able to help

Assessment comes first. We test each cuff tendon separately, look at how your shoulder blade moves, and check your neck, because neck problems can mimic shoulder pain. If there has been a significant injury or your arm is clearly weak, we can arrange an online GP consultation for an ultrasound scan or MRI and a specialist opinion.

The core of treatment is physiotherapy with a progressive loading programme: starting with isometric holds that calm the tendon, then building to resisted rotation and controlled overhead work. Evidence suggests this kind of graded exercise is the most important part of recovery. Around this we use hands-on techniques — joint mobilisation, IASTM and cupping for the tight muscles that develop in the upper trapezius and chest — and kinesiology taping to support better shoulder blade position while you retrain it.

For stubborn, long-standing tendinopathy, focused shockwave therapy may help stimulate the tendon's repair response. Therapeutic ultrasound and interferential therapy can be useful for pain in the early stages. Our posture scan can show how your shoulder sits relative to your spine, which helps guide the exercise plan.

What you can do at home

• Reduce — do not stop — the activities that hurt; cut overhead pressing volume rather than avoiding the gym entirely
• Keep the arm moving through pain-free ranges several times a day
• Try an isometric hold: press the back of your hand gently against a wall for 30–45 seconds, a few times a day
• Sleep on your back or the other side, with a pillow under the sore arm
• Avoid carrying heavy bags on the affected shoulder for now
• Check your desk set-up so your shoulders are not hunched toward your ears
