Physical Therapy Treatments for Shoulder Pain

When you begin physical therapy for shoulder pain, your doctor or physical therapist will use a combination of targeted techniques to relieve pain, restore function, and strengthen the shoulder joint. These evidence-based treatments are designed to improve motion, reduce stiffness, and prevent future injuries.

Range of Motion (ROM) Exercise

Gentle, controlled movements—both active (performed by you) and passive (assisted by your therapist)—help reduce stiffness and increase flexibility in the shoulder joint. These movements are essential for restoring motion, particularly in patients with frozen shoulder or limited mobility after an injury or surgery.

Your therapist may guide you through pendulum swings, where you gently swing the injured arm while leaning forward slightly, or assisted stretches using the opposite hand to gently pull the arm across the body.

Strengthening Exercises

Once your initial pain and stiffness improve, your therapist will introduce strengthening exercises for the rotator cuff, deltoids, and scapular stabilizers. These exercises help support the shoulder blade, rotator cuff tendons, and surrounding muscles to improve shoulder stability and prevent future injuries.

Examples include external rotations with a resistance band or controlled arm lifts to shoulder height, where you will be asked to slowly raise and slowly lower your arm.

Flexibility and Stretching

To restore balance and improve posture, stretching exercises target tight muscles in the chest, back, and shoulders. An example of a chest stretch would be to stand facing a doorway with your arms stretched out against the wall on either side. As you lean into the doorway, you will feel the strength in your chest.

Joint Mobilization

Your therapist may use gentle, hands-on techniques to move the shoulder joint, shoulder blade, and collarbone through their natural motions. These small, precise adjustments help increase joint flexibility, reduce stiffness, and improve the shoulder’s overall range of motion. This approach is particularly beneficial when scar tissue or frozen shoulder has limited your mobility.

Soft Tissue Mobilization / Massage

This hands-on treatment targets tension in the muscles and connective tissues around the shoulder and neck. By addressing muscle tightness and spasms, soft tissue mobilization promotes relaxation, increases blood flow, and supports recovery. It can also help improve posture and relieve discomfort in the upper body, especially after repetitive shoulder injuries.

Pain-Relief Modalities

In addition to exercise and manual therapy, your therapist may use several pain-relief modalities to enhance healing and comfort during therapy sessions:

  • Heat and Cold Therapy: Heat helps relax tight muscles, while cold reduces inflammation and swelling in the shoulder joint.
  • Electrical Stimulation (TENS): Gentle electrical pulses stimulate muscles and nerves to reduce pain and promote healing.
  • Therapeutic Ultrasound: Deep heat produced by sound waves encourages tissue repair and reduces stiffness around the shoulder blades and rotator cuff tendons.
 

Each of these modalities complements your personalized treatment plan, allowing your doctor or physical therapist to adjust your care as your shoulder heals. Over time, these methods help relieve shoulder pain, restore functionality, and prevent future injuries.

Physical Therapy Exercises for Knee Pain

Physical therapy for knee issues aims to improve motion, reduce stiffness, and prevent future injuries. Effective physical therapy exercises for knee pain include:

  • Straight leg raises: Lie on your back with one leg bent (so the thigh muscles are relaxed) and the other leg straight. Tighten the quad and slowly lift the straight leg toward the height of the bent knee.
  • Hamstring curls: Stand (holding a chair for balance), slowly bend one knee to bring your heel toward your buttocks. Strengthening the hamstring muscles supports the knee joint.
  • Leg extensions and other strengthening exercises: Use a slight bend in the knee, keep heels flat, and work under control to protect the knee joint.
  • Half squats: With knees bent slightly, perform shallow squats to build strength gradually. This helps reduce strain on the knee joint and stabilizes muscles, reducing risk of future injuries.

Post-Surgical Physical Therapy

Post-surgical physical therapy is crucial for a full recovery. The American Association of Orthopaedic Surgeons recommends exercising for 10 to 15 minutes, 2 or 3 times a day in the early phase. Your orthopaedic surgeon or physical therapist will inform you of which exercises are appropriate for you.

Key elements of post-surgical physical therapy include the following:

  • Pain relief and protection: In the early phase of recovery, your physical therapist focuses on reducing pain, swelling, and inflammation using methods like ice therapy, heat therapy, electrical stimulation (TENS), and therapeutic ultrasound. These techniques help protect the injured area while promoting circulation and comfort.
  • Motion restoration: Once your pain is under control, gentle range of motion (ROM) exercises begin. Your therapist may help you gently move the injured arm or leg, bent at the joint, to prevent stiffness and scar tissue buildup. For the shoulder, this may include pendulum swings to reduce tightness, while for the knee, controlled straight leg raises and leg extensions. These exercises restore flexibility and prevent frozen shoulder or joint stiffness.
  • Strength rebuilding: As healing progresses, targeted strengthening exercises are introduced to support the muscles around the joint. These may include half squats, hamstring curls, or resistance band work to build stability in the upper body and lower body. The goal is to help you gradually increase strength and restore functionality without overloading the injured shoulder or knee.
  • Functional return: In the final stage, therapy shifts toward restoring your ability to perform everyday activities like reaching, walking, or climbing stairs. Your therapist will integrate specific exercises that mimic real movements, helping you slowly return to your normal routine, improve coordination, and prevent future injuries.

When to Start Physical Therapy

The timing of your physical therapy really matters. Starting physical therapy sooner rather than later can significantly affect your outcome. In the context of shoulder pain, waiting too long can lead to a frozen shoulder, increased scar tissue, and more complex rehabilitation.

Here’s a quick guide:

  • If you’ve just had an injury or surgery: Start as soon as your surgeon or physical therapist clears you. This is often within days or weeks.
  • If you are managing shoulder pain without surgery: If daily activities are significantly impacted (raise your arm, use the injured arm for everyday tasks) or the pain is persistent, contact a physical therapist.

What to Expect from a Physical Therapy Appointment

Your first physical therapy appointment will generally follow these steps:

  1. Evaluation: The physical therapist asks about how you injured your shoulder or knee, what your pain is like, how your upper body or lower body movement is restricted, and what your goals are (return to everyday activities, sports, work).
  2. Assessment of motion and strength: They will check your range of motion (shoulder height, shoulder blades movement), look at your knee joint and leg muscles (thigh muscles, hamstring muscles), and test strength in arms, hips, upper body, and legs.
  3. Treatment plan development: They will create your own treatment plan, including specific exercises, stretching routines, mobilization, and home exercises.
  4. Hands-on and active work during the session: You might start with gentle swing or pendulum movements for the shoulder, or half squats, or leg bent exercises for the knee, depending on your condition. You’ll learn how to do them safely.
  5. Home exercise prescription: The therapist will show you home exercises (for the injured shoulder or knee) and explain how to perform them, how often, and what to monitor (pain, stiffness, swelling).
  6. Progress monitoring and goals: As you complete therapy sessions and home exercises, expectations for return to normal motion, improved strength, reduced pain, and prevention of future injuries will be discussed. The goal is not only to fix today’s injury but also to prevent future injuries.

FAQs About Physical Therapy

How long does physical therapy for shoulder pain usually take?

A dislocation typically causes immediate severe pain, deformity, and inability to move your arm. A strain may be painful, but usually does not cause the shoulder to look visibly out of place.

Seek medical help immediately. Avoid trying to push the joint back in yourself. Use an ice pack to reduce swelling while waiting for care.

Most patients wear a sling for a few weeks, depending on the severity of the injury and whether there was a complete dislocation.

No. Many cases improve with closed reduction and physical therapy. Surgery is usually recommended only for repeat dislocations or when there is significant tissue damage.

Yes, especially with targeted exercises aimed at strengthening shoulder muscles, improving stability, and preventing future dislocations.
