This study introduces a therapeutic exercise for postural asymmetry, specifically the Left Anterior Interior Chain (AIC) pattern. The technique aims to improve lumbopelvic-femoral alignment, function, and reduce pain, showing promising results in case studies.
Area of Science:
- Orthopedics
- Sports Medicine
- Physical Therapy
Background:
- Lumbopelvic-femoral conditions are frequently linked to musculoskeletal and respiratory asymmetries, often manifesting as a Left Anterior Interior Chain (AIC) pattern.
- This pattern involves trunk, rib, spine, pelvis, and hip joint asymmetries, leading to a tendency to bear weight on the right leg and shift the center of gravity rightward.
- Associated impairments include a tight left posterior hip capsule, weakened left adductors, internal obliques (IO), and transverse abdominus (TA), alongside shortened right-sided anterior outlet muscles and a decreased diaphragmatic zone of apposition (ZOA).
Purpose of the Study:
- To introduce and describe a therapeutic exercise technique for addressing impairments associated with the Left Anterior Interior Chain (AIC) postural asymmetry.
- To highlight the potential benefits of this exercise in improving lumbopelvic-femoral alignment, function, and pain reduction.
- To provide a foundation for future research into this novel therapeutic intervention.
Main Methods:
- The study describes the "Right Sidelying Left Respiratory Adductor Pull Back" exercise, a therapeutic technique designed to correct postural asymmetries.
- This exercise targets the left posterior ischiofemoral ligament, ZOA, right anterior outlet, and left anterior inlet muscles.
- It aims to activate and shorten left adductors and left IO/TA muscles while inhibiting and lengthening paraspinals.
Main Results:
- The exercise is utilized by physical therapists, physical therapist assistants, and athletic trainers for "repositioning" the lumbopelvic-femoral region.
- Four published case studies using similar exercises reported a 100% improvement in function and pain intensity for individuals with a Left AIC pattern.
- These findings suggest significant potential for this exercise in managing related impairments.
Conclusions:
- The described exercise technique is an effective initial intervention for improving lumbopelvic-femoral alignment in patients with a Left AIC pattern.
- Clinical observations and preliminary case studies indicate substantial improvements in function and pain reduction.
- Further research is warranted to validate the efficacy and long-term effects of this therapeutic exercise.

Mechanism of Breathing III: The Accessory Muscles
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
