Before Impingement Happens Shoulder impingement occurs when soft tissues get pinched during arm elevation. It does not happen suddenly. Mobility restrictions and movement patterns create conditions for impingement over time. Recognizing risk allows intervention before damage occurs. These five signs indicate elevated impingement risk. The 5 Signs 1. Pain When Raising Arm Overhead A painful arc during arm elevation, typically between 60-120 degrees, indicates structures being compressed. This is the classic impingement pattern. Pain with overhead movement is the earliest warning sign. 2. Rounded Shoulder Posture Forward-rounded shoulders narrow the subacromial space where impingement occurs. The worse your shoulder posture, the less room exists for soft tissues. Rounded posture mechanically increases impingement risk. 3. Decreased Overhead Reach Full overhead reach requires shoulder mobility and thoracic extension. Restricted reach indicates compensation patterns that increase impingement likelihood. If overhead movement has declined, risk has increased. 4. Clicking or Catching During Shoulder Movement Sounds during shoulder movement indicate structures not tracking smoothly. Clicking or catching suggests tissues are being pinched or displaced during movement. These sounds precede impingement symptoms. 5. Weakness With Arm Elevated Difficulty maintaining strength with arm overhead indicates rotator cuff compromise. The muscles may be irritated or partially impinged. Overhead weakness signals structures under stress. Start your 14-day free trial for shoulder health programs. Impingement Prevention Exercises Shoulder CARs JME 186 Sitting in your chair, extend one leg forward. Then, extend your upper body over that leg and hold for a stretch. Thoracic Extension JME 171 Sitting in your chair, raise one leg up and in front of you. Then, bend at your knee to find 90 degrees and then return to a straight position. Shoulder Mobility JME 189 *Desk Required: With one hand on your desk, bend your upper body forward while maintaining the position of your hand on the desk. Feel a gentle stretch in your forearm and then return to the start. Reducing Impingement Risk Impingement prevention requires improving shoulder mobility, thoracic extension, and rotator cuff function. Address posture that narrows subacromial space. Create room for structures to move without compression. Start your 14-day free trial and protect your shoulders with simplmobility.
