About this study

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.

Who can participate

Inclusion criteria

  • healthy

Exclusion criteria

  • Acute backpain (thoracal or lumbar)
  • History of significant backpain (thoracal or lumbar) or radiating pain down the leg
  • Contraindications to PA mobilisation/manipulation
  • Spinal fractures
  • Spinal tumors
  • Surgical intervention in the thoracic and lumbar spine
  • Local infections of the spine or the surrounding tissue

Treatment and study plan

Spinal stiffness

Diagnostic Test

Spinal stiffness will be assessed with a device, which measures tissue compliance according to the concept of impulse-response

Primary outcomes

  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 outcomes

  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.
