About this trial
This is an interventional treatment trial for Low Back Pain focused on measuring Low back pain, Unstable shoes, Gait, Balance
Eligibility Criteria
Inclusion criteria:

5. Study Description
Brief Summary
Some physicians, physiotherapists and nurses use or even suggest unstable shoes in cases of low back pain. No studies on the real effects of these shoes on low back pain in health care professions have been carried out and therefore as yet there is no real evidence of their effectiveness. Thus the investigators assume that wearing unstable shoes over a period of six weeks could reduce low back pain and functional disability due to the changes of the gait and posture and may increase the quality of life.
The purposes of this study are:
To evaluate the modifications of pain level, functional capacity and quality of life among individuals with moderate level of non-specific chronic low back pain after wearing unstable shoes.
To quantify biomechanical modifications of gait and posture.
