Shoulder Impingement

A pinch or catch when you lift your arm overhead, reach behind your back, or sleep on the affected side often comes back to shoulder impingement. We sort out what is getting squeezed at our Burlington clinic and treat the full range of cases.

When the Space Up Top Gets Tight

The shoulder has a small bony arch on top, formed by the underside of the acromion. Several structures pass through the narrow channel underneath: the rotator cuff tendons, the long head of the biceps, and the subacromial bursa. Shoulder impingement is when one or more of those structures gets compressed or irritated as the arm moves through the space.

The clinical world has moved away from “impingement” as the sole label, partly because most cases involve a rotator cuff that has lost some of its capacity to control the joint. The newer term is subacromial pain syndrome. Same condition, broader explanation.

Impingement sits on a spectrum, from bursal irritation and a catching tendon at the mild end through thickened tendon tissue, partial tearing, or persistent bursitis. The shoulder pain we see day to day in the clinic often falls into this category, and most of it responds well to a properly structured treatment plan.

Why the Subacromial Space Runs Out of Room

The space under the acromion has limited room. Anything that reduces that space, or asks the structures inside to work harder than they can handle, can produce impingement symptoms.

Overhead work in trades like painting, drywall, and electrical
Sports with repeated overhead reaching, including swimming, tennis, and volleyball
Heavy pressing in the gym, particularly with poor shoulder blade control
Repetitive reaching above shoulder height across long shifts

Weakness in the rotator cuff that lets the upper arm bone ride higher in the socket
Stiffness or poor coordination of the shoulder blade
Forward-shoulder posture and tightness through the chest from desk work
Anatomical variations in the shape of the acromion that narrow the space

Mapping What Hurts and What Moves

The assessment starts with the story: where the pain sits, what brings it on, whether it builds through the day or catches with one movement, and whether sleep is being interrupted. Impingement overlaps with rotator cuff tendinopathy, biceps tendon problems, and frozen shoulder, so the story matters as much as any single test.

Hands-on testing follows. The Neer test lifts your arm forward with the shoulder blade stabilized. The Hawkins-Kennedy test rotates the shoulder inward at a bent-elbow position. The painful arc test asks where in your overhead range the pain shows up. None is perfect alone, but together with range, strength, and shoulder blade movement they anchor the diagnosis.

Imaging plays a supporting role. X-rays sometimes show a hooked acromion, but plenty of people with that anatomy never develop symptoms. Ultrasound and MRI are reserved for suspected tendon tears, cases not progressing as expected, or a surgical consult. We also rule out frozen shoulder, biceps tendon problems, and referred neck pain, since each has a different treatment path.

Opening the Door, Then Strengthening Around It

Why Strength Beats Rest for the Subacromial Space

The historical advice for impingement was rest, ice, and avoid overhead movement. Current evidence is much closer to the opposite. Loaded rehab targeting the rotator cuff and shoulder blade muscles is the most consistent way to reduce symptoms and keep them away.

In the irritable phase, we settle things down with manual therapy on the shoulder joint, shoulder blade, and upper back. Active Release Technique addresses the muscles guarding around the joint, usually the upper trap, pec major, and posterior cuff. Laser therapy and acupuncture help during the early weeks. Sleep position adjustments and modifying the obvious aggravators like overhead pressing usually bring symptoms down.

The middle and late stages are where the work that changes the picture happens. Strengthening the rotator cuff pulls the upper arm bone down into a better position in the socket, functionally opening up the subacromial space. The lower trapezius and serratus anterior restore the upward tilt of the shoulder blade that the cuff relies on. We progress from isometrics to bands to dumbbells, then back to the movements that originally aggravated the shoulder. You can’t go wrong with strong.

Stubborn cases sometimes benefit from shockwave therapy or a short-term cortisone injection. Subacromial decompression surgery has fallen out of favour because the research has not supported it over a good rehab program. Mild cases settle in four to eight weeks, established impingement in two to three months, and long-standing cases or partial tears in three to six months.

How We Treat Shoulder Impingement in Burlington

Chiropractic Treatment

Our chiropractors evaluate how the shoulder joint, the shoulder blade, and the upper back are moving together, since restrictions in any of those areas tend to feed impingement symptoms. Active Release Technique addresses the soft tissue tightness that builds up around the joint, particularly the posterior cuff, pec major, and upper trap. Graston Technique helps when chronic tissue changes have developed in cases that have been hanging around for months.

Massage Therapy

Our massage therapists work on the muscle tension that builds up when a shoulder has been compensating for weeks or months. Releasing the posterior cuff, deltoid, and upper trapezius makes it easier to load the shoulder through full range without protective guarding. Acupuncture is often added during the irritable phase for pain control and to support sleep.

Physiotherapy

Our physiotherapists build the loading program that does most of the long-term work. Rotator cuff strengthening, shoulder blade control, and progressive overhead loading form the core of every plan. Shockwave therapy is used for stubborn cases that have not responded to loading alone, particularly when calcific deposits are part of the picture. Laser therapy supports healing during the early irritable phase.

What Impingement Recovery Looks Like

Trying to skip from a sore shoulder back to full overhead training is the most common reason cases drag on.

Calming the Joint

We work on bringing irritation down with manual therapy, soft tissue work, and modalities. The most obvious aggravators are modified while sleep, daily reach, and general conditioning stay protected.

Reclaiming Control

Once symptoms are predictable, we start rebuilding rotator cuff and shoulder blade control with isometric holds, light resistance band work, and movement retraining. The goal is restoring the basic mechanics the shoulder relies on under load.

Loading the Cuff

Progressive resistance work loads the rotator cuff and the shoulder blade muscles directly. Eccentric and end-range training prepare the shoulder for the kind of loads that will show up in sport, work, or the gym.

Back to Overhead

Overhead, pressing, and pulling tasks return step by step. We test the shoulder under realistic conditions before clearing the demands that caused the problem in the first place.

Shoulder Impingement: Questions We Hear in the Clinic

These answers reflect the patterns we see day to day. Every shoulder presents differently, and a proper hands-on assessment is the most reliable way to know what is happening with yours.

Is shoulder impingement the same as a rotator cuff problem?

They overlap heavily but are not identical. Impingement describes a mechanism, where structures under the acromion get compressed during arm movement. The rotator cuff is the most common structure involved, but the bursa and the long head of the biceps are often part of the picture too. Many cases of impingement are rotator cuff tendinopathy presenting with the classic painful arc pattern.

How long does shoulder impingement take to heal?

A mild case caught early can settle in four to eight weeks. Established impingement with tendon changes usually takes two to three months of consistent rehab. Long-standing cases or those involving partial rotator cuff tears often need three to six months before the shoulder feels reliable through full overhead range.

What exercises should I avoid?

The exercises that consistently bring symptoms on are the ones to modify, not necessarily eliminate. Overhead pressing, upright rows, lateral raises past shoulder height, and bench at an aggravating angle are the common culprits. Most of these can be reintroduced once rotator cuff and shoulder blade strength have caught up.

Do I need surgery for impingement?

Almost never as a first step. Subacromial decompression surgery has fallen out of favour for most impingement cases because the research has not shown it to outperform a good rehab program. Surgery is more often considered for full thickness rotator cuff tears with significant functional loss, younger patients with high physical demands, or cases that have not progressed despite consistent rehab.

Will I need an MRI or X-ray?

Not always. Most cases are diagnosed clinically through pain pattern, range testing, and the standard impingement tests. X-rays sometimes show acromial shape that contributes to the picture but are not required for diagnosis. MRI or ultrasound becomes useful when we suspect a significant tendon tear or when symptoms are not progressing as expected.

Can I still train while it recovers?

Usually yes. We modify the aggravators and keep the rest of your training intact. For most lifters that means temporarily reducing overhead pressing volume, changing the angle of certain exercises, and adding rotator cuff and shoulder blade work to the warm-up. Total rest tends to weaken the muscles the shoulder needs most, which slows recovery.
