Lumbar Kinematics in People With the Low Back Pain

The Effect of Lumbar Disc Herniation on the Kinematics in Lumbo-pelvic Region During Daily Living Activities.

This study evaluates the effect of lumbar disc herniation on kinematics in the lumbopelvic region during daily living activities.

Lumbar disc herniation (LDH) is one of the causes of low back pain and contributes to increasing the socio-economic problem. Depending on the reason for the dysfunction, various classifications describing the level of advancement are used. The literature on the subject commonly uses the division into protrusion and extrusion of the intervertebral disc, as approved by the American Society of Neuroradiology.

The lumbopelvic kinematics, including gait and daily living activities, can be affected by the LDH: protrusion or extrusion. This pathology may be different due to the direction of disc migration: centre, left, right or all mentioned. Therefore, we believe that from the different direction of the disc migration the different symptoms can be observed.
