Various types of postural deformities are as follows:
- Spinal Curvature
- Flat Foot
- Knock Knees
- Bow Legs
- Round Shoulders
- Spinal Curvature: This type of deformity is related to spine. This deformity is caused by carrying excessive weight beyond capacity. In another way, 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. Although 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:
(a) Kyphosis (b) Lordosis (c) Scoliosis
- Flat Foot: Our feet act as the base of support for the body in standing, walking, running and jumping. Flat-foot is commonly found among newly born babies but it becomes a postural deformity if it still persists during lateral childhood. The children with flat-foot deformity cannot be efficient sportspersons. Such children feel pain in feet. They face problem in standing and walking. It is easy to observe whether a person has flat-foot 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 flat-foot. In fact, there should be proper arch of the feet.
- Knock Knees: Knock knees is one of the major postural deformities. In this deformity, both the knees knock or touch each other in normal standing position. The gap between 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, they cannot be good players and even they are not selected in defence services.
- Bow Legs: ‘Bow legs’ is also a postural deformity. Approximately, it is opposite to knock-knees position. If there is wide gap between the knees when standing with feet together, the individual has bow legs. In this deformity, knees are widely 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: ln this postural deformity the shoulders become round and sometimes they seem to be bent forward.
