Dr. Tom Walters, an orthopedic physical therapist, shares four exercises that may help individuals with shoulder pain, particularly those experiencing issues with their rotator cuff. The focus is on addressing pain that occurs on the outside of the shoulder and may extend down the arm, often due to the supinatus muscle and its tendon.

The first exercise emphasized is the active assisted range of motion. This technique is beneficial for those who have trouble lifting their arm unaided due to pain. The exercise involves using a tool like a broomstick or a golf club to assist the affected arm with movement, aiming to reduce pain while maintaining mobility. Dr. Walters suggests performing this exercise four to five times a day and completing 10 to 15 repetitions each time.

Two-way isometric exercises are recommended for individuals with acute symptoms who need to activate the rotator cuff without actual movement. These exercises include two positions: external rotation and abduction, typically performed against a wall or doorway with a 30 to 45-second hold, repeated five times throughout the day.

Position the elbow at a 90-degree angle and press the back of the hand into a doorway, simulating an external rotation. The goal is to engage the rotator cuff muscles using moderate resistance, keeping the discomfort level mild.

In the third phase, focus shifts to strengthening through sideline external rotation exercises. This can be accomplished lying on the side of the non-affected arm with a weight, like a dumbbell or household item. The exercise involves slow, controlled movements to reinforce the external rotation, aiming for three sets of 8 to 15 repetitions.

The final exercise, scaption, targets the rotator cuff more intensively. Using a dumbbell, lift the arm in a V-shape aligned at a 45-degree angle with the thumb up, called the full can position. Perform three sets of 8 to 15 repetitions with a weight that avoids intense pain, to gradually increase shoulder strength.

"Isometrics not only help build strength but may also reduce tendon pain."

Dr. Walters concludes with a note on safe practice, suggesting these exercises can be performed daily as long as the pain remains manageable.
