Q.Explain the causes and corrective measures of any three of the following postural deformities: Bow Legs, Flat Foot, Round Shoulders, Lordosis, Kyphosis, Scoliosis.

Postural Deformity Types – A First Look

Think about how you sit right now. Are your shoulders rolled forward? Is your lower back collapsed into the chair? Most of us, after a few hours of study or screen time, settle into a shape that is not quite straight. That is the seed of the idea: a postural deformity is a persistent deviation of the body from its normal, balanced alignment.

The key word is persistent. Everyone slouches sometimes, but when the body stays in that misaligned position even when you try to stand straight — when the muscles and bones have adapted to the wrong shape — that is a deformity. It is not a disease or an injury; it is a habit of the body that has become structural.

Why does it matter?

A well-aligned body distributes weight evenly through the skeleton, so muscles work efficiently and joints are not strained. A deformed posture forces some muscles to overwork and others to weaken, leading to pain, fatigue, and eventually to reduced mobility or even damage to the spine and joints. For a commerce or humanities student, the practical concern is this: long hours of desk work, carrying heavy bags, and poor sitting habits are the perfect recipe for developing these deformities. Knowing about them is the first step to preventing them.

The main types of postural deformity

There are several common patterns. Each has a distinct shape and a distinct cause.

Kyphosis (round back or hunchback)

This is an exaggerated forward curve of the upper spine. Imagine the letter C, with the opening facing forward. The shoulders roll inward, the chest caves in, and the head juts forward to compensate.

• Common cause: Sitting hunched over a desk or phone for years, weak upper back muscles, and tight chest muscles.
• What you might notice: A visible hump at the top of the back, difficulty standing up straight, and sometimes neck or shoulder pain.

Lordosis (swayback or hollow back)

This is an exaggerated inward curve of the lower spine. The abdomen protrudes forward, and the buttocks stick out. The pelvis tilts forward.

• Common cause: Weak abdominal muscles, tight hip flexors (from sitting too much), and sometimes pregnancy or obesity.
• What you might notice: A pronounced arch in the lower back, lower back pain, and a forward-tilted pelvis when standing.

Scoliosis (lateral curvature)

This is a sideways curve of the spine, often forming an S or C shape when viewed from behind. One shoulder may be higher than the other, or one hip may stick out.

• Common cause: Often unknown (idiopathic), but can be congenital or caused by muscle imbalances. It frequently appears during the growth spurt in adolescence.
• What you might notice: Uneven shoulders, a prominent shoulder blade on one side, an uneven waist, or one hip higher than the other.

Flat foot (pes planus)

The arch of the foot collapses, so the entire sole touches the ground. This can affect the alignment of the ankles, knees, and hips.

• Common cause: Weak foot muscles, improper footwear, or prolonged standing on hard surfaces.
• What you might notice: Pain in the arch or heel, ankles that roll inward, and fatigue in the feet and legs after standing.

Knock knees (genu valgum)

The knees touch each other when standing with the feet apart. The ankles remain separated.

• Common cause: Weak hip and thigh muscles, obesity, or rickets (vitamin D deficiency). It is normal in young children but should correct by age 6–7.
• What you might notice: Difficulty walking with a normal gait, knee pain, and an awkward appearance when standing. …
