POSTURE AND POSTURAL DEFECTS
Posture is the way the body is held while standing, sitting, and walking. It can be defined as the alignment of the body.
Postural defects refer to an abnormal curvature of the spine which is often associated with sickness (es) that has to do with postures.
There is a correct posture of the body for everything we do either standing, walking, running, sitting, or sleeping, and good posture gives us a smart appearance which shows we are sensitive and attentive.
Good posture is an erect position whereby there is neither forward nor backward bending of the spinal column
KINDS OF POSTURE
- Sitting posture
- Standing posture
- Walking posture
- Running posture
- Sleeping posture
CORRECT STANDING POSTURE
In standing properly:
- The positions should be easy, not forced.
- The head should be well up.
- The chin is slightly drawn inward.
- The back of the head and the knees should be in one straight line.
- The shoulder should be held back in their natural hopping position with the chest forward and the abdomen in and the heels together.
- The weight of the body should rest on the outer edges of the feet.
- The arms should hang easily at the sides with the palms turned inward and the fingers slightly bent.
EVALUATION
- Explain the meaning of posture
- Mention and demonstrate four kinds of postures
POSTURAL DEFECTS
This refers to an abnormal curvature of the spine which is often associated with sickness (es) that has to do with postures. There are different types of postural defects- these are:
- Kyphosis (humped back or rounded back)
- Scoliosis
- Lordosis (hollow back)
- Flat foot
- Knocked knees
- Bowed-legs
- Wry neck
1. KYPHOSIS (ROUND SHOULDER)
Definition: kyphosis is regarded as the round shoulders which involve the bones and muscles of the back to assume a haunch or humped condition.
- SCOLIOSIS (LATERAL CURVATURE)
Definition: scoliosis is the lateral curvature of the spine; that is, it is the sideway bending of the body. It involves one shoulder being elevated more than the other. It affects the spine column and the two shoulders.
- LORDOSIS (HOLLOW BACK)
Definition: lordosis is defined as the abnormal curvature of the spinal column. This is the backward bending of the spinal column of the body. The tommy or stomach is usually big. The person is usually huge or lanky to carry the weight of the big stomach.
- FLAT FOOT
Definition: A flat foot is a condition in which the arch of the foot is flattened which starts or stretches from the heel to the big toe. It involves the tearing of the ligaments supporting the arch of the foot. It is the most common kind of foot trouble. In the normal foot, only the heel, toes, and outer border of the foot touch the ground.
- BOWED LEGS (VARUS KNEE)
Definition: Bowed legs are a condition in which in which the legs appear “bow” to the outside. In a bowed-leg situation, the patella would fall to the outside of the anterior leg line.
- KNOCK-KNEE LEG/K-LEG (VALGUS KNEE)
Definition: The knock-knee leg is the opposite of the bowed legs. It is a deviation where the patella falls inside the anterior leg line. Bowed legs and knock-knee legs are usually the result of faulty skeletal development.
- WRY NECK: This is a condition that makes a person hold his or her neck at a tilt while the chin is pointed in the opposite direction.
