When it comes to overhead sports, like baseball, swimming, or volleyball, athletes place tremendous strain on their upper bodies, often resulting in unique challenges like thoracic spine flattening. This condition, which involves a reduction in the natural curve of the thoracic spine, is increasingly recognized as a risk factor for several injuries in these athletes. Below, we’ll dive into the causes of thoracic spine flattening, the potential downstream injuries it may lead to, and effective strategies that can help athletes stay in top form.
Causes of Thoracic Spine Flattening
Thoracic spine flattening is often linked to the repetitive overhead motion seen in sports like baseball and swimming. When athletes extend and rotate their upper bodies frequently, they are prone to developing imbalances, especially in the thoracic spine. These movements, combined with high forces, can cause the spine to adapt to a flatter posture, reducing the natural curve (or kyphosis) that provides stability and shock absorption.
Poor posture plays a role here, too. Many athletes spend time in positions that exacerbate forward head and shoulder posture, limiting thoracic mobility. When these athletes transition to overhead activities, they’re starting from a restricted range of motion, which pushes the spine further out of alignment. Tightness in the shoulder and chest muscles also contributes to thoracic flattening, as tight pectoral muscles pull the shoulder blades forward, limiting the ability of the thoracic spine to maintain its normal curve.
Limited thoracic mobility creates compensations across the body. With reduced movement in the thoracic spine, the body may shift stress to other areas, like the shoulder joint or lumbar spine, setting the stage for future injuries.
Potential Injuries Linked to Thoracic Spine Flattening
1. Shoulder Injuries: As thoracic spine mobility decreases, it alters the movement mechanics of the shoulder blade and upper arm, increasing the risk of impingement or rotator cuff injuries. A lack of proper thoracic extension can also mean that the shoulders take on more force than intended, wearing down soft tissues over time. This compensatory movement puts an overhead athlete at high risk of conditions such as shoulder impingement and labral tears, which are common injuries in baseball and volleyball players.
2. Lower Back Pain: Flattening of the thoracic spine can lead to excessive lumbar lordosis (lower back arching) as the body seeks to balance its posture. This increases strain on the lower back, making it more prone to pain and injury, which could impact an athlete’s ability to perform and potentially lead to chronic lower back issues.
3. Scapular Dyskinesis: This condition occurs when the shoulder blade moves abnormally, often due to a lack of proper muscle recruitment. Over time, scapular dyskinesis affects shoulder stability and strength, increasing the risk of shoulder injuries. For athletes, these compensatory patterns are difficult to manage without targeted therapy, as they contribute to the repetitive stress and high injury rates associated with sports.
Our Approaches to Address Thoracic Spine Flattening
1. Restoring Thoracic Mobility
The first step in managing thoracic spine flattening is improving thoracic mobility through stretching and dynamic exercises. Techniques like the “cat-cow” stretch or forward thoracic rotations are effective for athletes as they increase the flexibility of the thoracic spine, allowing it to move naturally without compensation from the lower back or shoulders. Forward-reaching movements, paired with exhalation, help relax tight back and chest muscles, creating a more neutral spine position.
Another essential technique is the “squat bar reach,” which helps correct thoracic alignment by positioning the body’s center of mass more posteriorly, effectively countering the forward-leaning posture that often accompanies thoracic flattening. A combination of these movements, performed consistently, can improve range of motion in the thoracic spine and reduce the strain on neighboring joints and tissues.
2. Core Strengthening and Posterior Chain Activation
Strengthening the core and posterior chain (glutes, hamstrings, lower back muscles) is essential for athletes with thoracic spine flattening. Exercises like planks, deadlifts, and rows stabilize the spine and encourage proper alignment throughout the body. Glute recruitment exercises are particularly effective because they help balance the natural curve of the spine, relieving pressure on both the lower back and shoulders. As the posterior chain strengthens, it reduces the need for compensatory movement patterns, allowing the thoracic spine to maintain its optimal position.
3. Scapular Control and Shoulder Mobility
A lack of scapular control can worsen thoracic spine flattening, so physical therapists often focus on exercises that improve scapular stability. Activities like serratus anterior activation and subscapularis stability help athletes control the position of their shoulder blades, which reduces strain on the thoracic spine. Specific stretching, like the sleeper stretch or cross-arm stretch, can improve shoulder mobility, reducing pressure on the shoulder joints and allowing for smoother movement during overhead activities.
4. Breathing Techniques
Proper breathing techniques may not be the first thing you think of, but they can have a surprising impact on thoracic spine health. Deep, controlled exhalation exercises engage the core and relax the upper chest and shoulder muscles, effectively reducing thoracic stiffness. By teaching athletes to fully exhale and engage their diaphragm, physical therapists help release tension in the upper body, allowing the thoracic spine to adopt a more natural curve. Deep breathing techniques are an often-overlooked strategy but can be incorporated easily into pre- and post-training routines to keep the spine in optimal health.
5. Sport-Specific Rehabilitation
Finally, we work to integrate sport-specific movements to prepare athletes for return to play safely. These activities incorporate elements of the athlete’s sport, like throwing or swinging, but are modified to ensure that all those elements mentioned are in sync. This type of rehabilitation reduces the risk of re-injury by training the body to perform overhead movements without relying on compensatory patterns.
Thoracic spine flattening is a common but manageable condition for overhead athletes. With the right physical therapy interventions, athletes can restore thoracic mobility, improve posture, and reduce the risk of injuries in the shoulder, back, and beyond. While the repetitive demands of overhead sports may contribute to the issue, a combination of targeted stretches, strengthening exercises, and breathing techniques can help athletes maintain their performance and avoid injury. If you’re an athlete experiencing similar issues, working with a physical therapist who understands these specific demands can be invaluable in helping you to perform at your best.
