Clinical Significance

These exercises have significant impact on chronic low back pain . When pressure is placed on the posterior aspect of the lumbar vertebral with extension, disc herniation can occur. This is due to increased lumbar lordosis; lumbar lordosis would decrease by limiting the pressure placed on the posterior aspect of the lumbar vertebra. The decrease in pressure would improve by improving the flexion of the vertebral disc, leading to decreased disc herniation, thus reducing the incidence of chronic low back pain. The exercise open the intervertebral foramen to provide additional lumbar stability.[2]

When patients perform the exercises regularly.

  • it reduce pain,
  • improve the stability of the lower pelvis,
  • increase the range of motion.
