Elbow Pain, Could the Shoulder be to Blame?

by Julia Glick, PT

As therapists in a clinic located inside of a large tennis club, we are seldom surprised when a number of our patients each year present with lateral epicondylitis – or, as it is more commonly known, tennis elbow. Lateral epicondylitis pain usually occurs over the outside of the elbow where many of the forearm muscles attach, an area that experiences a lot of strain in tennis. However, even those of us who aren’t on the courts every week should be aware of it: it is also common in people who spend a lot of time at the computer or perform lots of gripping during their day. 

Despite the fact that lateral epicondylitis pain feels like it is centered in the elbow, it is important to look at the whole arm. Many people who come to us for tennis elbow have unsuccessfully tried exercises on their own that focus on the wrist and elbow, and are surprised when we turn our attention to the shoulder. Most specifically, the muscles that control shoulder blade position, such as the lower trapezius and serratus anterior, are crucial when treating the elbow, as the position of the whole arm is determined by the orientation of the shoulder blade. 

In fact, several research articles have come out in the past few years that focus on the role weakened shoulder blade stabilizers plays in lateral epicondylitis. Lucado et al. and Day et al. found that people with lateral epicondylitis had significantly weaker lower trapezius and serratus anterior musculature than people without any lateral elbow pain. In a case study performed by Bhatt et al., the research team only treated a woman’s shoulder blade stabilizers and were able to resolve her lateral epicondylitis. Essentially, these studies agree that the muscles that help pull the shoulder blade back and keep it stable also control the position of the arm and elbow: when it comes to prevention of elbow pain, shoulder blade strength and position matters.

Interested in finding some exercises that target the lower trapezius and serratus anterior to help maintain the shoulder blade in its optimal back position? I’ve included some below:

Easier Lower Trapezius

Lie on stomach and roll up a small towel under forehead and place hands on back of head/neck. Squeeze shoulder blades back and down toward opposite pants pocket and lift up elbows. Hold for 5 seconds and perform 5-10 repetitions.

Harder Lower Trapezius (Y)

Lie on stomach and roll up a small towel under forehead. Lift your arms up so they make a “Y” shape. Squeeze your shoulder blades back and down toward opposite pants pocket and lift your arms. Hold for 5 seconds and perform 5-10 repetitions. 

Serratus Anterior Wall Slides

Put your forearms on the wall and push your shoulder blades apart and into the wall. Keep this pressure into the wall and slide your arms up and down. Perform 5-10 repetitions.

Try these exercises and let us know what you think! If you do have pain that is persistent, please stop by to speak with one of our skilled clinicians, who can help you with your injury.

Swimmer's Shoulder: What You Should Know

by Stephanie Korso, PT

Swimming is a phenomenal way to improve cardiovascular fitness, burn lots of calories, strengthen muscles and prevent disease. As a non-contact sport, there is little risk for acute and catastrophic injuries, but there is still risk for injury. Prevention, early recognition and early treatment are key to managing swimming injuries and remaining active.

The most common swimming injury is swimmer's shoulder, which refers to any shoulder pain related to swimming. Up to 90% of swimming injuries involve the shoulder, and as many as 73% of swimmers may report shoulder pain during their career. The repetitive nature of swimming contributes to overuse and predisposes swimmers to shoulder injury.

Although swimmer's shoulder can involve any shoulder dysfunction, such as tendinosis or impingement syndrome, shoulder instability is the most common. This is because the same factors that improve swimming performance also contribute to shoulder instability:

Increased Shoulder Range of Motion
Increased shoulder range of motion helps reduce drag and allows for greater stroke length, both of which contribute to increased swimming speed. However, increased range of motion also contributes to increased ligament laxity and increased strain on rotator cuff muscles, which contributes to decreased stability.

Increased Shoulder Adduction and Internal Rotation Strength
Up to 90% of forward propulsion in swimming comes from the upper body. The pectoralis major and latissimus dorsi muscles, responsible for shoulder adduction and internal rotation, are the primary muscles that create the propulsive force needed in swimming. Increased strength in these muscles contributes to increased swimming speed, but it also leads to muscle imbalance and further instability.

Prolonged, Fatiguing Shoulder-Intensive Training
An experienced swimmer knows that swimming involves both shoulder strength and endurance. Training involves long work-outs that fatigue muscles. As rotator cuff and scapular muscles fatigue, shoulder instability increases.

The primary goals in management of swimmer's shoulder are to reduce inflammation, increase stability and return the athlete to full activity as soon as possible. Initially, the athlete will need to modify activity so that no pain is experienced. During this time, the athlete will implement exercises to decrease muscle imbalances, improve rotator cuff and scapular strength, and improve muscle endurance. The athlete may then gradually increase activity as pain decreases. Physical therapy is often helpful not only to guide progressions of strength exercises, but to also improve spine mobility and help release overworked pectoralis major and latissimus dorsi muscles.

As the saying goes, prevention is better than the cure. Therefore, incorporating exercises to strengthen the rotator cuff and scapular muscles into training regimens prior to onset of pain is optimal.
