Postural disorders
Pelvic tilt relates to the rotational position of the pelvis, with misalignment posing risks to posture, movement and nerve damage (Healthdor, 2024).
Anterior pelvic tilt occurs with frontal rotation of the pelvis, raising posteriorly, causing excessive curvature of lumbar vertebrae (lordosis). Resulting in muscular imbalance, weakened gluteal muscles, tight hip flexors, and increased spinal pressure.
Conversely, posterior tilt occurs with pelvic rotation raising anteriorly and lowering posteriorly, decreasing lumbar curvature, increasing anterior vertebral pressure. Also resulting in tightened hamstrings and weakened abdominals.
Improper Lifting techniques
Continuous activities namely heavy lifting, apply strain on the spine. Overtime this pressure weakens disc tissues, increasing vulnerability of slipping or bulging (Fausel, n.d.).
Vertebral discs comprise of nucleus pulposus; a soft jelly-like substance located in the annulus fibrosus, between the vertebral body endplates. Supporting impact and movement absorption.
Herniation's occurs when the nucleus pulposus protrudes or ruptures the annulus, resulting in myelopathy from compression of spinal nerves (Dydyk, 2023).
Approximately 90% of all herniation occur in the lower back with a posterior bulge between L4 and L5 vertebrae (trunk flexion and extension)(NEMSON, n.d.).
