Clinical Trial Summary

The objective of this study is to examine the influence of body position and additional axial load on spinal stiffness in young healthy adults.

Description:

Spinal stiffness plays an important role in the assessment of the spine in the clinical daily routine. It is often performed as a manual PA-pressure test in the prone position. The spinal stiffness is the result of the resistance from the active, passive and neurological subsystems, like muscles (active), ligaments, joint capsule and the skin (passive). Further research had shown, that the spinal stiffness depends also from other factors. It is increased by axial compression. A better understanding of spinal stiffness leads to novel insights into spinal stabilization mechanisms.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Spinal stiffness	posterior-to-anterior spinal will be assesd in prone and upright body position and in upright body position with additional axial.; The device measures tissue compliance according to the concept of impulse-response. A force of exact 80 Newton will be applied from the device to the process spinous. The expected impulse-response (result) will be between 40 Newton and 70 Newton.	Day one of the study
Secondary	Pain during measuring spinal stiffness	Visual Analogue Pain Rating Scale will be used if the particepants feel any pain during the measurement.The participant will be asked to rate his pain intensity on a straight line (100 millimeter) with two endpoints.	Day one of the study
