• The infrasternal angle determines which muscles are deficient when a rib flare is present and therefore determines the appropriate treatment direction. — Rib Flares, Posterior Thorax Expansion, and Movement Screen Assessment
• In narrow infrasternal angle individuals, the internal obliques and transversus abdominis are the deficient muscles failing to pull the rib cage inferiorly. — Rib Flares, Posterior Thorax Expansion, and Movement Screen Assessment
• In wide infrasternal angle individuals, the external obliques are the deficient muscles failing to draw the rib cage down. — Rib Flares, Posterior Thorax Expansion, and Movement Screen Assessment
• Treatment arm direction for rib flares must be matched to infrasternal angle presentation: forward reach for narrow, overhead reach for wide. — Rib Flares, Posterior Thorax Expansion, and Movement Screen Assessment
• This exercise is specifically designed for individuals who have a narrow infrasternal angle. — Normalize Spinal Position With a Narrow Infrasternal Angle
• The exercise is especially appropriate when there is no flexion limitation present. — Normalize Spinal Position With a Narrow Infrasternal Angle
• The infrasternal angle is measured bilaterally, with approximately 90 degrees total as a working reference norm, and asymmetry exists when one side significantly deviates from 45 degrees. — Asymmetrical Infrasternal Angle, SI Joint Testing, and Imaginary Lat Syndrome
• The infrasternal angle is measured at the xiphoid process by tracing the costal margins bilaterally with the thumbs, with a clinical target of approximately 90 degrees total. — Neck Strength, Infrasternal Angle, and Joint Displacement: Clinical Realities
• The narrow ISA represents the furthest progression from the normal state, while the wide ISA is an intermediate stage in the biomechanical continuum. — Asymmetrical Infrasternal Angle, SI Joint Testing, and Imaginary Lat Syndrome
• Treatment for asymmetrical ISA should begin with the prolonged sigh on the narrow side to avoid worsening the narrow angle before both sides are more dynamic. — Asymmetrical Infrasternal Angle, SI Joint Testing, and Imaginary Lat Syndrome
