Posture Syndromes: Summary

Pelvic Crossed Syndrome (Kyphosis-Lordosis Posture):

- Postural Assessment: Forward head, hyperextended cervical spine, abducted scapulae, increased thoracic kyphosis, increased lumbar lordosis, anterior pelvic tilt, flexed hips, slightly hyperextended knees, and slight plantarflexion of ankles.
- Weak Muscles: Neck flexors, upper erector spinae, external obliques, and hamstrings (potentially).
- Strong Muscles: Neck extensors, hip flexors, and lumbar erector spinae.
Swayback Posture:
- Characterized by a weak anterior chain and a strong posterior chain.

Lateral Imbalance Posture:
- Characterized by tightness in leg muscles.
- Postural Assessment: Slightly extended cervical spine, slight thoracolumbar curve convex to the right, higher pelvis on the left, left hip adducted and slightly medially rotated, right hip abducted, left leg appears longer due to postural adduction.

- Weak Muscles (Left Side): Tensor fasciae latae (TFL), hip abductors, fibularis longus and brevis.
- Strong Muscles: One-joint hip flexors.
Upper Crossed Syndrome (Forward Head Posture + Rounded Shoulders):
- Characterized by tightness in specific muscles and weakness in opposing ones.
- Tight Muscles: Upper trapezius (UFT), levator scapulae, pectoralis major, and pectoralis minor.
- Weak Muscles: Rhomboids, serratus anterior, lower trapezius (LFT), and deep neck flexors.
