The Influence Body Position and Axial Load on Spinal Stiffness

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03495843

Brief 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.

Condition or disease Intervention/treatment
Healthy Diagnostic Test: Spinal stiffness

Detailed 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.

Intervention Details:
  • Diagnostic Test: Spinal stiffness
    Spinal stiffness will be assessed with a device, which measures tissue compliance according to the concept of impulse-response

Primary Outcome Measures :
  1. Spinal stiffness [ Time Frame: Day one of the study ]

    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.

Secondary Outcome Measures :
  1. Pain during measuring spinal stiffness [ Time Frame: Day one of the study ]
    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.
