Anatomical pedagogical device for use in e.g. healthcare establishment, has abdominal muscles with strap connecting lower part of sternum to pubis to shorten/extend muscles length for inducing hyperpressure and amplitude limitation

摘要

The device has a plastic vertebral column (1), and a posterior vertebral muscular chain including posterior strings (2) attached to a skull (3) and a sacrum (5), respectively, by upper hook-screws. A psoas muscle has anterior strings (6) attached to cervical and lumbar vertebrae and a femur, respectively. Abdominal muscles have an anterior strap (8) that connects a lower part of sternum to pubis to shorten or extend the length of the abdominal muscles using attachment hooks, length adjustable nodes (7) or a valve for inducing deformation, hyperpressure and articular amplitude limitation.
