Likely Cause

Head is laterally flexed / tilted to one side

• Short neck lateral flexors (and/or long OS neck lateral flexors)
• Compressed vertebrae
• Pelvis is elevated
• Arch is collapsed
• Spine is laterally flexed
• Occipital condyles are different size
• Hearing difficulties OS
• Short spine rotators (consider same side and opposite side rotators) – spine is rotated to OS and/or legs are rotated (SS leg is laterally rotated and OS leg is medially rotated)
• Torticollis
• Scapula is elevated

Spine is laterally flexed to other side

• Scoliosis
• Short spine lateral flexors (especially QL) on concave side
• Bigger hemipelvis
• Longer leg
• Habitually sitting with same side foot tucked under
