Shoulder Rehab for Rotator Cuff Injuries

Phase 1: Pain Management and Protected Motion (Weeks 0-6)

After rotator cuff repair, the tendon needs time to heal to bone. You will wear a sling for 4-6 weeks, and movement is limited to passive range of motion. Goals include managing pain and swelling, preventing frozen shoulder, and maintaining elbow, wrist, and hand mobility.

• Pendulum swings: leaning forward, letting the arm swing in gentle circles
• Passive forward flexion using a pulley or the other arm
• Passive external rotation with a stick
• Scapular squeezes and retraction exercises

Avoid lifting anything heavier than a coffee cup. For conservative (non-surgical) management, this phase is shorter and active motion can begin earlier.

Phase 2: Active Motion (Weeks 6-12)

Once the sling is removed, active range of motion begins. The rotator cuff muscles now start moving the arm under their own power, but without resistance. Goals include active forward flexion to at least 140 degrees and active external rotation to at least 40 degrees. Isometric rotator cuff exercises begin to gently activate the healing tendons. Scapular stabilization exercises including wall slides, serratus punches, and low rows ensure proper shoulder blade mechanics.

Phase 3: Strengthening (Weeks 12-20)

Strengthening begins with light resistance and progresses gradually. This is where the rotator cuff muscles rebuild strength for daily activities and sport demands.

• External rotation with resistance band (cornerstone of rotator cuff strengthening)
• Internal rotation with resistance
• Side-lying external rotation with light dumbbell
• Prone horizontal abduction (I, Y, T exercises)
• Progressive shoulder flexion and abduction with increasing resistance

Increase resistance only when you can perform 3 sets of 15 repetitions with good form and no pain.

Phase 4: Advanced Strengthening and Return to Activity (Months 5-9)

The final phase targets return to full function including overhead activities and sport. Exercises progress to overhead pressing, plyometric ball tosses, sport-specific progressions, and full-body exercises like cable chops and push-up variations. Return to sport or heavy labor typically occurs between 6-9 months post-repair.

When to Push, When to Rest, and Non-Surgical Rehab

Use the 24-hour rule: if your shoulder is no worse 24 hours after exercise, the load was appropriate. Sharp pain at the surgical site or compensatory movement means you are doing too much. Many rotator cuff tears are managed without surgery — studies show 60-80% of patients achieve satisfactory outcomes with physical therapy alone. Conservative rehab moves faster since there is no repair to protect.
