The Throwing Motion and Its Impact on Performance
Can understanding the mechanics of the throwing motion help to understand why it may cause shoulder pain, the symptoms of a shoulder problem, the diagnosis, and the treatment options available?
Throwing a Ball and Shoulder Pain
The throwing motion is a complex shoulder movement that requires the mechanics of muscles, tendons, joints, ligaments, and bones. They all must move in a synchronized and stable pattern to move the shoulder joint. When these mechanics are interrupted or altered, inflammation can result in pain symptoms. (Wardell M., Creighton D., & Kovalcik C., 2022)
Throwing Motion
Distinct phases characterize the throwing motion:
- The wind up
- Cocking
- Acceleration
- Follow-through
- Deceleration
- The rotator cuff and shoulder muscles sequentially guide the movements for effective throwing mechanics. (Wardell M., Creighton D., & Kovalcik C., 2022)
- The labrum stabilizes the ball in the socket of the shoulder.
- The shoulder blade rotation coordinates with the arm to ensure mobility. (Itoigawa Y. et al., 2023)
The throwing motion generates high torque and acceleration forces acting on the shoulder joint and the surrounding muscles, ligaments, and tendons.
Causes of Pain
Pain when throwing can come from the:
- Shoulder blade
- Shoulder joint – cartilage and labrum
- Rotator cuff muscles and tendons
- Nerves that control the muscles’ function
The shoulder blade is attached to the upper back by ligaments, muscles, and tendons. The various muscles and tendons that control the movement of the shoulder blade impact movements. Abnormalities of any area can lead to shoulder dysfunction and pain when throwing. (Wardell M., Creighton D., & Kovalcik C., 2022) The most common is the tightness of the posterior shoulder capsule, causing a loss of normal internal rotation of the shoulder. If this is causing pain, individuals may notice that they can’t reach up as high on the side with the painful shoulder when reaching behind their back.
Symptoms
Whether an athlete or playing catch in the backyard, shoulder function abnormalities can cause significant pain. Some symptoms include.
Aching Pain
- Often deep in the shoulder or extending down the upper arm.
Dead Arm
- Lack of strength in the throwing motion.
Pain at Night
- Pain can awaken you from sleep.
Diagnosis
Finding a healthcare provider familiar with sports injuries can be helpful. They can best determine if a structural abnormality needs to be addressed. (American Academy of Orthopaedic Surgeons, 2021)
Treatment
Most can improve with nonsurgical treatments. The earliest phase of treatment is resting the joint and reducing inflammation. Treatments can include:
- Ice
- Anti-inflammatory medications
- Cortisone injection
Once the inflammation has subsided, the source of the discomfort can be addressed.
Physical Therapy
Therapy can include:
- A structured shoulder stretching and strengthening program will help.
- The physical therapist will focus on scapular mobility when managing shoulder joint problems.
Exercises may include: (American Academy of Orthopaedic Surgeons, 2024)
- Stretching to improve internal rotation or any other lost motion can help allow a more normal throwing motion.
- Strength exercises are often aimed at the rotator cuff, as these muscles initiate proper shoulder movements and stabilize the shoulder joint.
- Maintaining flexibility and strength of the periscapular muscles (muscles that attach to the scapula bone) is important to ensure that the scapular movements are coordinated with the throwing motion.
Suppose improvements are not made within three months of therapy, or individuals can’t return to competitive sports within six months. In that case, the individual may need to return to their healthcare provider or see an orthopedic specialist who may recommend surgery. (American Academy of Orthopaedic Surgeons, 2024)
