Between one-half and two-thirds of people experiencing shoulder pain are diagnosed with shoulder impingement, a repetitive strain injury that compresses the rotator cuff tendons and surrounding tissue.
Although this condition can affect individuals of any age, it’s common in those who frequently lift their arms overhead or support weight with their upper body.
Over time, repeated stress – especially when combined with poor posture or improper technique – can narrow the space at the top of the shoulder joint. This area, called the acromion, begins to place pressure on nearby tendons and soft tissue.
What Is Shoulder Impingement?
Shoulder impingement is a type of repetitive motion injury that develops when the bones of the shoulder press against the soft tissue and ligaments of the rotator cuff. This repeated compression irritates the tendons and bursa, causing inflammation and swelling. As the space within the joint narrows, these structures can become pinched between the humerus, scapula and clavicle, a condition known as subacromial impingement syndrome.
Recurring load-bearing activities are a major contributing factor. Even lifting weights overhead can strain the joint if muscles are weak, fatigued or improperly conditioned.
Individuals at higher risk include:
- Athletes without a consistent warm-up routine
- Weightlifters who increase resistance too quickly
- Baseball pitchers, tennis players and golfers
- Volleyball players and swimmers
- Manual laborers, including construction workers, painters and warehouse employees
In some cases, shoulder impingement may also occur due to:
- A fall or direct injury to the shoulder
- Bone structure differences that reduce joint space
- Osteoarthritis
- Muscle weakness or imbalance
- Tight connective tissue or thickened ligaments
Common symptoms include:
- Limited ability to raise the arm overhead or out to the side
- Pain when lifting, reaching or throwing
- Shoulder discomfort while sleeping, especially on the affected side
Without treatment, ongoing irritation can lead to more serious conditions like bursitis, tendonitis or a rotator cuff tear. For this reason, it’s important to seek medical attention if your shoulder pain persists.
How Physical Therapy Helps Shoulder Impingement
Physical therapy is often one of the first treatments recommended before considering injections or surgery. Sessions focus on restoring proper movement patterns, reducing inflammation and strengthening the muscles that support the shoulder joint.
Most care plans include a combination of evaluation, guided exercise, hands-on therapy and education.
Evaluation and Assessment
Your physical therapist will begin with a detailed assessment to understand how your shoulder moves and where limitations exist. This evaluation helps identify muscle imbalances, joint restrictions and movement patterns causing pain. Your therapist may:
- Observe your ability to lift and rotate your arm
- Compare strength between both shoulders
- Perform hands-on mobility testing
- Ask you to describe when and where pain occurs
You’ll also discuss your daily activities, including work tasks, sports and hobbies, to better understand how your shoulder is being used.
Targeted Exercises
Exercise is a central part of physical therapy for shoulder impingement. Your therapist will guide you through movements designed to restore strength, mobility and balance while reducing strain on the joint. Your program may include:
- Range of motion exercises to improve flexibility and restore natural shoulder mechanics
- Strengthening exercises for the shoulder blade, rotator cuff and surrounding muscles
- Postural training to correct rounded shoulders and reduce joint compression
- Functional movement training to improve lifting, reaching and overhead activities
These exercises begin under supervision in our clinic and gradually transition into a home program to support continued recovery.
Manual Therapy and Pain Management Techniques
In addition to exercise, physical therapists use hands-on and supportive treatments to reduce pain and improve joint mobility. These may include:
- Manual therapy, where the therapist gently guides the shoulder to improve movement
- Soft tissue techniques to release muscle tension
- Ice, heat or other modalities to reduce inflammation
- Education on posture and movement habits to prevent further irritation
These treatments help create a safer environment for healing while improving your daily comfort.
Preventing Long-Term Shoulder Problems
One of the most important benefits of physical therapy is learning how to protect your shoulder moving forward. Your therapist will help you identify movement patterns, posture habits or strength deficits that contributed to your injury.
With proper strengthening, mobility work and movement training, many patients can return to their normal activities without pain.
