Overview
Shoulder impingement syndrome happens when soft tissue — usually the supraspinatus tendon or the subacromial bursa (a fluid-filled cushion under the tip of your shoulder blade) — gets pinched during overhead movement. This guide gives you a general, phase-by-phase path for calming things down and rebuilding pain-free movement.
The good news: research consistently shows that a well-structured exercise program works as well as or better than many other treatments for this condition (JOSPT systematic review update). This is not a shoulder that usually needs surgery first.
This guide is general education. A physiotherapist can confirm the exact structures involved and adjust the plan to your case.
Who This Guide Is For
- People diagnosed with shoulder impingement syndrome (sometimes called subacromial pain syndrome)
- People with pain reaching overhead, reaching behind the back, or sleeping on the affected side, who have had this confirmed by a health professional
Pair this guide with the shoulder impingement syndrome injury page for a full explanation of causes and symptoms.
Goals of Rehabilitation
- Reduce pain during overhead and reaching movements
- Improve the space and mechanics under the acromion (the bony bump on top of your shoulder blade)
- Strengthen the rotator cuff and shoulder blade stabilizers so the joint tracks correctly
- Correct posture and movement habits that contribute to pinching
- Return to sport, lifting, or overhead work without recurring pain
Phase 1: Early Stage
Typical timing: Weeks 0–3.
Goals:
- Calm irritated tissue and reduce pain
- Avoid positions that reproduce sharp pain
- Begin gentle motion to prevent stiffness
Exercises and stretches:
- Pendulum exercise — gentle passive motion with minimal muscle effort
- Isometric shoulder holds — builds early rotator cuff activation without joint movement
- Doorway pec stretch — eases tightness in the chest muscles that can pull the shoulder forward and narrow the space under the acromion
- Cross-body stretch — gentle mobility for the back of the shoulder, kept within comfortable range
A note on overhead-lifting exercises like the empty can raise: this is usually introduced later once pain has settled, and some people do better with the alternative "full can" arm position described on that page.
Criteria to move to Phase 2:
- Pain during daily activities is noticeably lower
- You can lift your arm partway overhead without sharp pain
- Resting pain and night pain are improving
Phase 2: Middle Stage
Typical timing: Weeks 3–8.
Goals:
- Strengthen the rotator cuff and scapular (shoulder blade) muscles
- Improve shoulder blade positioning and control during arm movement
- Gradually increase pain-free overhead range
Exercises and stretches:
- External rotation with band — strengthens the infraspinatus and teres minor, which help center the upper arm bone in the socket
- Scapular retraction row — builds mid-back strength that supports better shoulder blade position
- Wall slides — trains controlled overhead movement with support
- Serratus anterior punch — strengthens the muscle that rotates the shoulder blade upward during reaching
- Towel stretch — internal rotation — gently improves reaching-behind-the-back mobility
Criteria to move to Phase 3:
- Full or near-full pain-free overhead range of motion
- Noticeably stronger on resisted rotation and reaching tests
- Minimal to no pain with daily tasks
Phase 3: Late Stage / Return to Activity
Typical timing: Weeks 8–12+.
Goals:
- Build strength and control at higher loads and speeds
- Prepare for sport-, gym-, or job-specific overhead demands
- Prevent recurrence through lasting movement habits
Exercises and stretches:
- Prone Y-T raise — builds trapezius endurance for sustained shoulder blade control
- External rotation with band — progressed to heavier resistance and faster speeds
- Overhead triceps and shoulder stretch — maintains flexibility as load increases
- Posterior capsule stretch — supports healthy joint mechanics during high overhead demand
Criteria to consider yourself "returned":
- Full strength and pain-free motion under sport- or job-specific load
- No pain flare-up after a full training session or work shift
- Confidence performing the specific overhead task that originally caused trouble
Signs You're Progressing Well
- Overhead reach is getting easier week to week
- Pain no longer wakes you at night
- You need less modification during workouts or work tasks
- Strength on resisted tests is trending up
Signs You Should Slow Down or See a Professional
- Pain that spikes sharply during exercise and doesn't settle afterward
- New weakness, especially difficulty lifting the arm at all
- No improvement after 4–6 weeks of consistent, correctly performed rehab
- Numbness or tingling down the arm
If these occur, check in with a physiotherapist or physician rather than pushing through the plan as written.
