NOTE

POSTURE AND POSTURAL DEFECTS

 Posture refers to the position and alignment of the body parts in relation to each other and to the surrounding environment. It involves the arrangement of bones, muscles, joints, and connective tissues that support the body's stability and balance in both static (stationary) and dynamic (moving) situations.

Factors that influence posture

Several factors can influence posture, including:

  1. Muscular strength and flexibility: Weak or tight muscles can affect posture by pulling the body out of alignment.
  2. Body mechanics: The way we move, sit, stand, and lift objects can impact posture.
  3. Ergonomics: The design of workspaces, furniture, and equipment can influence posture during activities like sitting at a desk or using a computer.
  4. Genetics: Some individuals may inherit structural characteristics that predispose them to certain postural tendencies.
  5. Injury or trauma: Previous injuries or trauma to muscles, joints, or bones can alter posture.

Characteristics of good posture

Good posture is characterized by:

  1. Alignment: Proper alignment of the spine, shoulders, hips, and limbs, maintaining a neutral position without excessive curves or deviations.
  2. Balance: Equal distribution of weight across the body's support structures, minimizing strain on any particular area.
  3. Stability: Firmness and control of the body's position, achieved through activation of core muscles and proper engagement of supporting muscle groups.
  4. Comfort: Feeling relaxed and at ease while maintaining the posture, without undue tension or discomfort.

Postural defects

Postural defects refer to abnormalities in the alignment of the body while standing, sitting, or moving. Common types include:

  1. Kyphosis: Excessive outward curvature of the spine, often causing a hunched or rounded back.
  2. 2. Lordosis: Excessive inward curvature of the spine, leading to a swayback appearance.
  3. Scoliosis: Sideways curvature of the spine, resulting in an S or C shape.

EVALUATION: 1. Define posture

  1. Identify 5 factors that influence good posture.
  2. Mention 4 characteristics of good posture.
