The Importance of Shoulder Internal Rotation for Optimal Health and Function

Dec 4, 2023


Shoulder internal rotation is a crucial movement that allows you to perform various daily activities with ease. Lack of mobility in this area can negatively impact your overall health and function, leading to discomfort, limited range of motion, and potential injuries. At IAOM-US, our team of highly skilled chiropractors and physical therapists specializes in improving shoulder internal rotation to help you achieve optimal health and wellness.

The Role of Shoulder Internal Rotation

Shoulder internal rotation refers to the movement of your arm bone inward towards your body. This movement allows you to perform essential tasks such as reaching behind your back, scratching your back, or tucking your shirt into your pants. It is a fundamental component of functional movement and is involved in various everyday activities.

Impact on Health

Proper shoulder internal rotation is essential for maintaining good posture, balance, and overall musculoskeletal health. When this movement is limited, it can lead to compensatory motions, potentially causing strain or discomfort in other areas of the body.

Individuals with limited shoulder internal rotation often experience difficulty with activities that involve reaching or lifting objects overhead. This limitation can also affect sports performance, hindering the ability to throw, swing, or serve with optimal power and accuracy.

Moreover, restricted shoulder internal rotation may contribute to the development of postural imbalances, such as rounded shoulders or a forward head posture. These imbalances can lead to muscle imbalances, joint dysfunctions, and increased susceptibility to injuries.

The Role of Chiropractors and Physical Therapists

At IAOM-US, our team of chiropractors and physical therapists are experts in assessing and treating limited shoulder internal rotation. They utilize a holistic approach, combining manual therapy techniques, specific exercises, and patient education to help restore proper shoulder mobility.

Chiropractors, with their expertise in spinal alignment and joint manipulation, can identify any structural or biomechanical issues contributing to limited shoulder internal rotation. By adjusting the spine and mobilizing the affected joints, chiropractors can help alleviate restrictions and improve overall function.

Physical therapists, through their extensive knowledge of the musculoskeletal system, can design personalized exercise programs to target the underlying causes of limited shoulder internal rotation. These exercises aim to increase flexibility, strengthen supporting muscles, and improve joint stability. Additionally, physical therapists can provide education on proper body mechanics and posture to prevent future limitations and injuries.

Exercises to Improve Shoulder Internal Rotation

Here are some effective exercises that you can perform to improve shoulder internal rotation:

  1. Doorway Stretch: Stand in a doorway with your arm out to your side and bent at a 90-degree angle. Place your forearm on the doorframe and gently lean forward, feeling a stretch in the front of your shoulder. Hold for 30 seconds and repeat on the other side.
  2. Underhand Towel Stretch: Hold a towel behind your back with one hand over your shoulder and the other hand behind your lower back. Gently pull the towel upward with your lower hand, feeling a stretch in your shoulder and upper arm. Hold for 30 seconds and repeat on the other side.
  3. External Rotation with Resistance Band: Attach a resistance band to a doorknob at waist height. Hold the band with your elbow bent at a 90-degree angle and close to your side. Rotate your forearm outward against the resistance of the band, then slowly return to the starting position. Perform 10-15 repetitions on each side.
