Explain any five common postural deformities.
✓
Answer
Various types of postural deformities are discussed below:
Spinal Curvature: This type of deformity is related to the spine. This deformity is caused by carrying excessire weight beyond one's capacity. In other words, we can say that weak muscles cause the formation of spinal curvature. The normal lumbar spine is characterised by a moderate anterior hyperextension curve, when viewed laterally. There is no absolute standard for the determination of the degree or extent of the anterior convexity of the normal lumbar curve. There are three types of spinal deformities.
Kyphosis.
Lordosis.
Scoliosis.
Flatfoot: Our feet act as the base of support for the body while standing, walking, running and jumping. Flatfoot is commonly found among newborn babies but it becomes a postural deformity if it still persists during later childhood. The children with flatfoot deformity cannot become efficient sportspersons. Such children feel pain in their feet when they run. They face problem while standing and walking. It is easy to observe whether a person has flatfoot deformity or not. Dip your feet in water and walk on the floor. If there is not a proper arch of footprints on the floor then you have the deformity of flatfoot. In fact, there should be proper arch of the feet for healthy feet.
Knock-knees: Knock-knees is one of the major postural deformities. In this deformity, both the knees-knock or touch each other while in normal standing position. The gap between the ankles goes on increasing. The individual faces difficulty in walking and running. He cannot walk or run in a proper manner. Owing to this deformity, people cannot be good players and may not be selected in defense services.
Bow Legs: Bow legs is also a postural deformity. It is opposite to knock knees position. If there is a wide gap between the knees when standing with feet together, the individual has bow legs or genu varum. In this deformity, knees are wide apart. There remains a wide gap between knees when a bow legged person keeps his feet together. This deformity can be observed easily, when an individual walks or runs.
Round Shoulders: In this postural deformity, the shoulders become round and sometimes they seem to be bent forward.
