Erector spinae muscles

0

The Erector spinae muscles (also known as extensor spinae) are a bundle of muscles and tendons, running more or less vertically throughout the lumbar, thoracic and cervical regions of the vertebral column.

They are part of a large and complex group of muscles that work together to support the spine, help hold the body upright and allow the trunk of the body to move, twist and bend in many directions.

The extensor muscles are attached to the posterior (back) of the spine and enable standing and lifting objects.  These muscles include the large paired erector spinae muscles, which help hold up the spine, and the gluteal muscles.

Unless these muscles are specifically exercised, back muscles and abdominal muscles tend to weaken with age.  Also, any episode of lower back pain that lasts for more than two weeks can lead to muscle weakness (since using the muscles hurts, the tendency is to avoid using them).  This process leads to disuse atrophy (muscle wasting), and subsequent weakening, which in turn causes more back pain because the muscles of the back are less able to help hold up the spine.

Physical therapy and back exercises to treat back pain in the lower spine usually focus on strengthening the flexor, extensor and oblique muscles to help reinforce support of the spine and in turn, reducing low back pain and sometimes eliminating the need for surgery.

Extensor muscle strength and flexibility are essential to maintaining a neutral spine position.  An unhealthy posture results when the curve is overextended called lordosis or swayback.  Proper posture corrects muscle imbalances that can lead to low back pain by evenly distributing weight throughout the spine.

The Role of the Erector Spinae in the Golf Swing

Poor spinal posture affects your golf swing much more than you would think.  When your spine is not able to move forward (flexion) and backward (extension) easily, this has a negative influence on the mobility of your shoulder blades and pelvis through the muscle connections between your spine and these body areas.  When your hips and pelvis become limited in their range of motion, your potential for injury is greatly increased, and the likelihood of improving your swing technique is greatly reduced.
