Sitting Posture and it's Effects on Spine


 

For many people a great deal of time is spent sitting at work, at school, at home, or in a car.  The posture of the pelvis during sitting can have a substantial influence on our spine. 

So what really happens during a poor posture?

Three major changes occur during a poor posture and let's use the slouched posture as an example. 

1) FORCE

When our lumbar (back) spine is flexed forward as you can see in the picture, the upper cervical (neck) is forced into an extended position to maintain the horizontal gaze at the computer monitor.    

2) PRESSURE

Over time this pressure on L4-L5 & L5-S1 can deform the disc and cause non-specific low back pain.  

3) COMPENSATION 

Now that you have mastered the art of slouching, overtime the body gradually but surely will go into adaptive shortening in the small neck muscles and ligaments leading to stress and tension at the base of the spine and neck region.  Also, in this poor posture, the body places greater demands on the tissues that normally resist flexion of the lower trunk.

Solution: 
- Awareness of the dynamics and long term hazards related to poor posture
- Massage Therapy 
- Strengthening and stretching the appropriate muscles 
- Massage Therapy 
- Ergonomic seats and lumbar support 
- Massage Therapy
