Rotator cuff tear

Explanation of Diagnosis

A rotator cuff tear means one or more of the tendons that help lift and stabilize your shoulder have been stretched, partially torn, or fully torn. These tendons attach the muscles of the shoulder to the upper arm bone, helping you raise your arm and keep the shoulder joint moving smoothly. Tears often happen gradually from wear and strain, or suddenly after a fall, heavy lift, or sudden overhead movement. Common symptoms include shoulder pain (often worse with reaching or lifting), weakness, trouble raising the arm, and sometimes pain at night.

Specific Work Modifications

• Use a “belt buckle to shoulder” rule: keep frequent tasks at waist to chest height and avoid reaching overhead.
• Take mini-breaks every 30–45 minutes to lower the shoulder, relax your grip, and change positions.
• Limit lifting objects with the arm away from your body; bring items close to your torso when carrying.
• Avoid repetitive overhead work and sustained arm elevation; alternate sides or vary tasks when possible.
• If your job involves computer work, raise your chair/desk so your elbows stay near your sides and your keyboard/mouse are at comfortable height.
• For workdays with flare-ups, use lighter loads and slower movements for a few days rather than pushing through sharp pain.

Specific Activity Modifications

• Avoid or reduce overhead sports and drills until pain and strength are improving (examples include throwing, serving, swimming strokes with heavy overhead reach).
• Pause strengthening that causes pinching or sharp pain, especially exercises done with the arm fully overhead or with heavy resistance.
• Choose shoulder-friendly cardio like walking or stationary biking while keeping arms relaxed and avoiding arm-swinging that triggers symptoms.
• When playing or working out, replace wide-range reaches with shorter range movements, such as controlled, chest-height motions.
• Be cautious with activities that involve sudden pulling or catching (tug-of-war, heavy racquet swings, sudden yard tool lifting) and scale them back.
• If night pain worsens after a particular activity, reduce that activity and consider adjusting timing to avoid late-day flare-ups.

Recommended Supplements

• Omega-3 fish oil, typically 1,000–2,000 mg per day of combined EPA and DHA, may help support healthy inflammation response.
• Vitamin D3, commonly 1,000–2,000 IU per day, may be helpful if your levels are low (ask your clinician if testing is appropriate).
• Curcumin (turmeric extract), commonly 500 mg 1–2 times per day with food, may help some people with musculoskeletal discomfort.
• Collagen peptides, commonly 10 g per day, may support connective tissue health when paired with appropriate rehab exercises.

Recommended Nutrition and Hydration

Diet Recommendations

• Aim for adequate protein at each meal to support tissue repair, often by including a palm-sized portion of lean protein (or equivalent) most meals.
• Choose an overall anti-inflammatory pattern with fruits, vegetables, whole grains, beans, nuts, and olive oil most days.
• Limit added sugars and highly processed foods, especially during symptom flares, since they can worsen inflammation for some people.
• Include healthy fats and omega-3 sources such as salmon, sardines, chia, or flax if you tolerate them.
• Get enough vitamin C and minerals from foods like citrus, berries, peppers, leafy greens, and beans to support normal healing processes.

Hydration Tips

• Drink water regularly through the day, and consider slightly more with exercise or hot environments.
• If you use electrolyte drinks, keep them low-sugar and use them mainly when you sweat heavily.

Home Exercise Prescription

Perform these exercises 4 to 6 days per week, staying in a comfortable range and stopping if pain sharply increases.

1. Pendulum (Codman) swings: Lean forward with your non-painful arm supported on a table, let the sore arm hang, then make small gentle circles and side-to-side swings, 30–60 seconds each direction, 2–3 sets.
2. Scapular retractions: Sit or stand tall, gently pull your shoulder blades back and down without shrugging, hold 5 seconds, repeat 10–15 times.
3. Table or wall slides (assisted range): Face a wall or use a table, use your other arm to help as needed, slide the hand forward and back only as far as it stays comfortable, 8–12 repetitions.
4. Isometric external rotation: Elbow at your side bent to 90 degrees, press your hand outward lightly into a wall or a folded towel (there should be no sharp pain), hold 10 seconds, repeat 8–10 times.
5. Supported shoulder extension: With a light stick or towel behind your back, gently draw the sore arm backward within comfort (use your other hand to help), hold 5 seconds, repeat 8–10 times.
