Should the Spine Be Straight?

Every spine has 4 natural curves

We have two primary kyphotic curves:

• Thoracic

• Sacral

And two secondary lordotic curves:

• Cervical

• Lumbar

How are these curves developed?

When a baby is born, their spine has a natural C-shaped curve (kyphosis), which includes the thoracic and sacral curves.

As they develop more muscle strength in the neck and begin to lift their head independently, the cervical lordotic curve starts to form.

Later, when they learn to sit, crawl, and stand, the lumbar lordotic curve develops.

What are the functions of these curves?

These natural spinal curves play a crucial role in absorbing impact from activities such as walking, running, and jumping.

They act as shock absorbers, distributing forces evenly throughout the body to reduce strain on the joints and muscles.

Additionally, these curves provide the flexibility and mobility needed for essential movements like bending forward and backward, rotating, and twisting.

What is the neutral degree of these curvatures?

The natural curvature of these curves ranges between 30 to 35 degrees.

When the curve deviates beyond this range—either exceeding or falling below it—imbalances begin to develop in the body. This uneven distribution of weight places excessive strain on certain areas, making the person more susceptible to fatigue, energy depletion, stiffness, and pain and even during routine activities.

Why is it important to maintain these natural curves?

Maintaining a balanced gait—the way we walk—is essential for overall musculoskeletal health.

When the spine's natural curvature is well-aligned, gait remains smooth and efficient, allowing for even weight distribution across both legs. However, when spinal curves become exaggerated or diminished, the body compensates with altered movement patterns.

These compensations may include uneven step length, excessive lateral sway, or increased impact on one side of the body. Over time, these irregularities can lead to muscle imbalances, joint stress, fatigue, and even pain in the lower back, hips, knees, or feet. Proper spinal alignment and core stability play a significant role in maintaining an efficient, pain-free gait.
