Definition

Unconscious adjustment of the tone of muscle accompanying every movement is called posture. It is the position in which someone holds their body when standing or sitting. It is a significant element of your long-term health. Making sure that you hold your body the right way, whether you are moving or still, can prevent pain, injuries, and other health problems.

Purpose – Making movement smooth and accurate and maintain the equilibrium.

Maintenance

Your spine has three natural curves – at your neck, mid back, and low back. Correct posture should maintain these curves, but not increase them. Posture is maintained by the integrative action of –

  • Spinal cord,
  • Brain stem,
  • Cerebellum,
  • Cerebral cortex

Proper posture:

  • helps decrease the abnormal wearing of joint surfaces that could result in arthritis.
  • prevents the spine from becoming fixed in abnormal positions.
  • prevents strain or overuse problems.
  • prevents a backache and muscular pain.

Proper posture requirements:

  • Good muscle flexibility
  • Strong postural muscles
  • A balance of muscles on both sides of the spine
