FOUR TYPES OF POSTURAL ALIGNMENT

FOUR TYPES OF POSTURAL ALIGNMENT

Normal spinal curves consist of a forward convex curve in the neck (cervical region), a curve that it is convex backward in the upper back (thoracic region) and a convex forward curve in the lower back (lumbar region). These can be described as a slight extension of the neck, a slight flexion of the upper back, and a slight extension of the lower back. When there is normal curvature in the lower back, the bony protrusions in the front of the pelvis are in a neutral position, as indicated by the anterior-superior iliac spines and pubic symphysis in the same vertical plane. In a bad postural position, the pelvis can be tilted anteriorly, posteriorly or laterally. Any tilt of the pelvis involves simultaneous movements of the lower back and hip joints. In anterior pelvic tilt, the pelvis is tilted forward, decreasing the angle between the pelvis and thigh anteriorly, resulting in flexion of the hip joint; the lower back arches forward, creating a greater forward curve (lordosis) in the lower back. In the posterior pelvic tilt, such as the pelvis is tilted back, the hip joints are extended, and the lower back is flattened. In lateral pelvic tilt, one hip is higher than the other, and the vertebral column curves convexly on the underside.

Head: neutral position, not tilted forward or backward.

Cervical spine: normal curve, slightly convex anteriorly. Shoulder blades: As seen in the photograph, they appear to be well aligned, flat against the upper back.

Thoracic back: normal curve, slightly convex on the back.

Lumbar spine: normal curve, slightly convex anteriorly.

Pelvis: neutral position, anterior-superior spines on the same vertical plane as the pubic symphysis.

Hip Joints: Neutral position, neither flexed nor extended. Knee joints: neutral position, neither flexed nor hyperextended.

Ankle joints: neutral position, leg vertical and at right angles to the sole of the foot.

In the lateral view, the anterior and posterior muscles attached to the pelvis keep it in ideal alignment. Previously,

the abdominal muscles are lifted and the hip flexors are lowered. Subsequently, the back muscles are lifted and the hip extensors are lowered. Therefore, the extensor muscles of the hip and anterior abdomen work together to tilt the pelvis back; The hip and lower back flexor muscles work together to tilt the pelvis forward.

Go ahead.

Cervical spine: hyperextended.

Shoulder blades: abducted.

Thoracic spine: increased flexion (kyphosis).

Lumbar spine: hyperextended (lordosis). Pelvis: anterior tilt.

Hip Joints: Bent.

Knee joints: slightly hyperextended.

Ankle Joints: Slight plantar flexion due to backward tilt of the leg.

Stretched and weak: neck flexors, upright spine, external oblique. The hamstrings are slightly stretched

but it may or may not be weak. The rectus abdominis is not necessarily elongated, because the depressed position of the chest compensates for the effect of the anterior pelvic tilt. The hip flexors are in a shortened position in both sitting and standing lordotic positions. However, the lower back muscles may or may not be tense. When sitting, your back may flatten. this combination

of the circumstances is related to the fact that the shortening of the lumbar muscles is less frequent than the shortening of the hip flexors

in this type of posture. Short and strong: neck extensors and hip flexors. The lower back is strong and may or may not develop

Lack

Head: neutral position.

Cervical spine: normal curve (slightly anterior).

Thoracic spine: normal curve (slightly posterior)

Lumbar spine: hyperextended (lordosis). Pelvis: anterior tilt.

Knee joints: slightly hyperextended.

Ankle Joints: Slightly plantar flexed.

Stretched and Weak: Front abdominals. The hamstrings are somewhat stretched, but they may or may not be

weak. Short and strong: lower back and hip flexor muscles. Head: forward.

Cervical spine: slightly extended.

Thoracic spine: upper part, greater flexion; below, straight.

Lumbar spine: flexed (straight).

Pelvis: posterior tilt. Hip Joints: Extended.

Knee joints: extended.

Ankle joints: slight plantar flexion.

Stretched and weak: hip flexors of a joint.

Short and strong: hamstrings. The abdominal muscles are often strong. Although the back muscles are slightly stretched when they are normal

the previous curve is eliminated, they are not weak. Sometimes the knees are slightly bent rather than exaggerated;

lying together with the flat back posture.
