Study Overview

Brief Summary

The main purpose of this study is to investigate if improvements in patient self-reported pain, symptoms, function and quality of life 12 months after Lumbar spinal fusion among patients that have good projected prognosis differ from those among patients with a poor projected prognosis.

The secondary purpose is to explore the underlying factors of the physiotherapists projected prognosis to identify objective and possible modifiable candidate prognostic factors for recovery.

Detailed Description

Background:

Over recent decades, an increasing number of patients with Chronic Low Back Pain (CLBP) undergo surgical lumbar spinal fusion (LSF). For many of the patients LSF is their last resort in the hope of a better life with less pain, disability and use of medication. Unfortunately, several reports show, that the pain level remains the same after LSF for many patients, and that consumption of medication remains unchanged in almost 50 % of the patients.

Knowing that characteristics such as maladaptive coping strategies, fear avoidance beliefs and pain catastrophizing seem to be predictive of worse outcome in pain, function and quality of life after surgery. It is important to assess how these individual factors in the postsurgical rehabilitation can be addressed.

The single physiotherapists have an essential role in mobilizing the LSF patient post-operatively. In clinical practice it is not enough for the physiotherapists to use their biomechanical understanding of LSF material and heeling processes, it is also essential to use a so-called "silent knowledge" of experience and personal interaction with the patient.

It remains unknown if this "silent knowledge" is a reliable predictor of the outcome of LSF surgery. If the physiotherapist can predict the outcome, it is important to explore which factors the physiotherapist rely their prognosis upon in order to identify objective and possible modifiable candidate prognostic factors for recovery.

Outcomes

Primary Outcomes

Oswestry Disability Index

Time Frame: 1 year

Disability will be measured using the Oswestry Disability Index. ODI is a validated measure of condition-specific disability originally developed for patients with LBP. The ODI consists of ten items regarding pain intensity, personal care, lifting, walking, sitting, standing, sleeping, sex life, social life, and traveling. For each item the patient chooses one of six answers, with 0 representing no difficulty in the activity and 5 representing maximal difficulty.

Secondary Outcomes

  • Health outcome and quality of life(1 year)
  • Questionnaire regarding postoperative rehabilitation(1 year)
  • Patient reported movement capacity(1 year)
  • Back Pain(1 year)
  • Leg Pain(1 year)
