Origin & Insertion
['Origin: Transverse processes of vertebrae', 'Insertion: Junction of lamina and spinous process above']
Synergistic Muscles
['Multifidi', 'Semispinalis']
Joints
['Vertebrae (1–2 levels)']
Primary Actions
['Segmental spinal rotation', 'Proprioception']
Nerve & Spinal Segment
Dorsal rami of spinal nerves
Segmental innervation
Interesting
Smallest transversospinalis group, key for proprioception. [Moore's]
Reversal of Action
Stabilize vertebra while thorax rotates
Common Dysfunctions
Segmental stiffness, impaired spinal proprioception
How to Stretch
Spinal rotation stretches in seated or lying.
Trigger Points
How to Strengthen
Rotational isometric drills.
Concentric Action
Assist spinal rotation and proprioception
Applications:
Trains segmental control for mobility and injury prevention
Eccentric Action
Control small segmental movement
Isotonic Action
Controlled spinal rotation drills
Related Conditions
['Facet dysfunction', 'Spinal instability']
Isometric Action
Maintain midline during spinal twist
