Question

What is the best position to carry an object to decrease the pressure on the spine and lower back according to biomechanics? Explain and give references

Answer 1

When our back is in its ideal position, with us standing straight up or lying flat, we're placing the least amount of pressure on the discs between vertebrae. When we sit down and cause the back to curve, we add close to 50 percent as much pressure to these discs as when we're standing.

Overview

• Good posture involves training your body to stand, walk, sit, and lie in positions where the least strain is placed on supporting muscles and ligaments during movement or weight-bearing activities.

• If any of the following guidelines causes an increase of back pain or spreading of pain to the legs, do not continue the activity and seek the advice of a doctor or physical therapist.

The spinal curves

• Your spine has natural curves that form an S-shape. Viewed from the side, the cervical and lumbar spines have a lordotic, or a slight inward curve, and the thoracic spine has a kyphotic, or gentle outward curve.

• The spine's curves work like a coiled spring to absorb shock, maintain balance, and to facilitate the full range of motion throughout the spinal column (see Anatomy of the Spine).
