How to Fix a Right BC Pattern - Steps For Addressing Upper Body Asymmetry

Understanding the Right Brachial Chain

Introduction to the Right Brachial Chain

• The right brachial chain is a concept from the Postural Restoration Institute, focusing on the upper half of the left AIC pattern.

• This video aims to explain how this concept relates to our natural asymmetrical patterns and emphasizes that the pelvis and upper body are interconnected.

Asymmetrical Patterns and Body Mechanics

• Individuals tend to lean towards their right side, necessitating trunk rotation to the left for balance and stability while walking.

• Counter-rotation occurs in the spine, particularly around T8, allowing for a neutral center of mass. This helps prevent falling over to one side.

Scapular Positioning and Breathing Dynamics

• The right shoulder drops due to trunk rotation, causing internal rotation of the right scapula and external rotation of the left scapula. This creates an imbalance in shoulder positioning.

• The diaphragm is asymmetrical; it is larger on the right side but tends to facilitate air movement into the left chest wall, leading to further expansion on that side over time.

Muscle Tightness Due to Asymmetry

• Prolonged postural patterns lead to tightness in specific muscles:

• Right internal rotators (e.g., latissimus dorsi) become tight.

• Right pec minor may also tighten, pulling that shoulder forward.

• Left-side muscles like pec major can become restricted as well.

Identifying Right BC Pattern Through Testing

• Objective tests can confirm if someone exhibits a right BC pattern:

• Restricted internal rotation of the right shoulder indicates compression within that rib cage area.

• Conversely, there may be less external rotation available in the left shoulder due to similar compressive factors affecting mobility.

Understanding Shoulder Mechanics and Asymmetries

Importance of Shoulder Measurements

• The discussion begins with the significance of shoulder internal and external rotation measurements, alongside shoulder flexion and trunk rotation.

• Proper scapular movement is crucial for shoulder flexion; limitations arise when the scapula cannot rotate upward or glide smoothly on the rib cage.

Impact of Scapular Positioning

• Limitations in trunk rotation are often observed, particularly towards the right side, due to spinal orientation affecting rib cage movement.

• Compensatory rotations can hinder proper orientation; expanding specific areas of the rib cage is essential for effective trunk rotation.

Individual Variability in Asymmetry

• Not everyone requires perfect symmetry; some individuals may live without issues despite asymmetries, while others may experience significant problems.

• If asymmetry leads to discomfort or functional issues, targeted interventions can help restore balance effectively.

Focus on Rib Cage Expansion

• Emphasis is placed on achieving rib cage expansion to enhance breathing variability and facilitate trunk rotation.

• Creating space between the spine and scapula on one side while expanding the opposite chest wall aids in improving shoulder mechanics.

Muscle Engagement for Improvement

• Key muscles involved include internal obliques and transverse abs on the left side to promote pelvic posterior rotation and rib cage compression.

• On the right side, engaging serratus anterior helps maintain scapular positioning against winging during arm movements.

Exercises for Targeted Expansion

• Facilitating low trap and triceps engagement supports downward scapular rotation while maintaining stability during reaching motions.

• Specific exercises targeting these muscle groups will be introduced to enhance expansion capabilities within the rib cage.

Practical Application: All-Four Left Posterior Mediainal Expansion

• An exercise setup involves placing a 2-inch book under the left knee while ensuring proper alignment of knees under hips and hands beneath shoulders.

• Maintaining a neutral cervical spine is critical; participants should be able to speak comfortably in this position.

Movement and Breathing Techniques for Rib Expansion

Initial Positioning and Breathing Technique

• Trevor is instructed to slightly tuck his body and gently push the floor away, ensuring the sternum remains elevated. This positioning helps in maintaining proper rib alignment.

• Trevor exhales gently through his mouth, simulating fogging a mirror, which engages his side abs. He should feel tension in these muscles while inhaling through the nose.

Right Side Expansion with Left Arm Reach

• The exercise focuses on right-side lying apical expansion while incorporating left arm reach and left adductor activity. This aims to open up the right side of the body while compressing the left.

• The setup requires a hemi 90/90 position where the left hip is fully extended in line with other joints, allowing for optimal right side opening.

Engaging Muscles During Movement

• Trevor's right arm is positioned far out to facilitate leaning into it, enhancing the stretch on the right side while closing off the left.

• As he exhales, he pushes down with his right knee to engage his left oblique more effectively. Maintaining this engagement during inhalation promotes further stretching of the right oblique.

Adjustments for Optimal Engagement

• After achieving a suitable seat height (90-degree bend at knees and hips), Trevor rolls back his pelvis to feel both sit bones before exhaling and bending sideways to engage outer abs.

• Extending his right arm creates space between humerus and trunk, engaging tricep and lower shoulder blade muscles as he breathes deeply.

Standing Supportive Passive Drill

• The standing supportive passive drill emphasizes securing hips while training trunk rotation independently from lower body movement. A stable surface at waist height aids this process.

• Weight distribution is crucial; 80% of weight should be on the left heel while 20% rests on the inner edge of the right foot arch, promoting correct knee positioning during movement.

Final Movements for Effective Stretching

• As Trevor exhales gently through his mouth, he feels engagement in his left side abs while ensuring proper knee alignment for inner groin activation.

• He rotates slightly with controlled movements to avoid overextending into low back discomfort, focusing instead on expanding through inhalation.

Understanding Body Mechanics in Movement

The Interconnection of Upper and Lower Body

• Emphasizes the importance of maintaining proper alignment in both the left heel and right foot arch while allowing the right knee to move forward. This highlights a holistic approach to body mechanics.

• Stresses that one cannot separate upper body issues from lower body dynamics, indicating that effective movement requires addressing both simultaneously.

• Encourages viewers to consider how various exercises impact both upper and lower body functions, suggesting that many exercises are designed with this interconnectedness in mind.

• Suggests monitoring improvement through assessment results, reinforcing the idea that progress is measurable when considering the whole body's functionality.

• Highlights the significance of understanding joint, tissue, and fascia connections within the human body, advocating for a comprehensive approach to physical assessments and training.
