Introduction Myofascial lines are chains of interconnected anatomical structures that functionally direct the basic motion patterns of the musculoskeletal system. They have previously been dissected in humans, where they describe the overall spinal motion of flexion, extension, lateral flexion and axial rotation. They are believed to play a role in functionality, connection, and balance of the body. The aim of this study was to investigate whether similar myofascial lines could be identified in the horse. Methods Five myofascial kinetic lines were dissected in 22 horses euthanized for unrelated reasons. The lines were the Superficial Dorsal Line (SDL), Superficial Ventral Line (SVL), Lateral Line (LL), Spiral Line (SL), and Functional Line (FL). Results SDL included hind limb flexors and the errector spinae group, which extend the hip and spine. SVL included hind limb extensors, abdominal muscles, and ventral neck muscles, which are structures with antagonistic functions to SDL. LL followed myofascial tissues along the side of the abdomen and produced latero-flexion of the spine. FL and SL formed helical lines concerned with spinal axial rotation. FL connected the front limb to the contralateral hind limb by crossing over the midline at the thoraco-lumbar level dorsal and ventral on the trunk. SL connected one side of the neck with the contralateral front limb and ipsilateral hind limb by a helical course around the body crossing over at the cervico-thoracic and lumbo-sacral junctions. Conclusions The SBL, SVL and LL complete a functional anatomical ring, which balances the dorsal, ventral and lateral motion patterns of the horse.

Myofascial lines are chains of interconnected anatomical structures that functionally direct the basic motion patterns of the musculoskeletal system. They have previously been dissected in humans, where they describe the overall spinal motion of flexion, extension, lateral flexion and axial rotation. They are believed to play a role in functionality, connection, and balance of the body. The aim of this study was to investigate whether similar myofascial lines could be identified in the horse.


Methods

Five myofascial kinetic lines were dissected in 22 horses euthanized for unrelated reasons. The lines were the Superficial Dorsal Line (SDL), Superficial Ventral Line (SVL), Lateral Line (LL), Spiral Line (SL), and Functional Line (FL).


Results

SDL included hind limb flexors and the errector spinae group, which extend the hip and spine. SVL included hind limb extensors, abdominal muscles, and ventral neck muscles, which are structures with antagonistic functions to SDL. LL followed myofascial tissues along the side of the abdomen and produced latero-flexion of the spine. FL and SL formed helical lines concerned with spinal axial rotation. FL connected the front limb to the contralateral hind limb by crossing over the midline at the thoraco-lumbar level dorsal and ventral on the trunk. SL connected one side of the neck with the contralateral front limb and ipsilateral hind limb by a helical course around the body crossing over at the cervico-thoracic and lumbo-sacral junctions.


Conclusions

The SBL, SVL and LL complete a functional anatomical ring, which balances the dorsal, ventral and lateral motion patterns of the horse. The helical FL and SL determine the spinal axial rotation. With minor exceptions all lines mirrored the human lines.
