The tip of the spinous process of the L4 vertebra was located by palpation, confirmed with a longitudinal scan, and cross-sectional images of the multifidus
muscles on the left side of the L4 vertebra were acquired (Figure 1).

Ultrasound image-guided exercise programs targeting the multifidus
muscle have been found to improve low back pain.
of the thoracolumbar spine in the horse.
The local muscles are located deeper and include the multifidus
, TrA, and IO; these provide stability to the lumbosacral spine .
They observed that the surface EMG activities of the longissimus and multifidus
muscles during a maximal isometric lumbar extension together with shoulder isometric horizontal abduction were greater by 69% to 84% compared with the maximal isometric lumbar extension alone.
(16) Some authors suggest that the entrapment may be due to spasms of the paraspinal musculature, mainly the multifidus
, the scapular stabilizers including the rhomboid and trapezius, or impingement due to degenerative changes in the thoracic spine and/or thoracic herniated discs.
Influence of feedback schedule in motor performance and learning of a lumbar multifidus
muscle task using rehabilitative ultrasound imaging: a randomized clinical trial.
The training concentrated on creating neutral spine and activation of lumbar multifidus
and transversus abdominus muscles with abdominal bracing techniques at the beginning.
"There are numerous muscles that make up the core, the deeper stability muscles (transverse abdominis, multifidus
and the pelvic floor muscles) and the larger global muscles (obliques, rectus abdominis and gluteus maximus),' says Holly.
Es importante que el entrenamiento con ejercicios especificos para la musculatura de espalda y abdomen incluya el transverso abdominal multifidus
para disminuir el dolor y la discapacidad en pacientes con dolor lumbar cronico.
