Immediate Effect of Hamstring Stretching in Patients With Chronic Low Back Pain
France90 participantsStarted 2020-07-03
Plain-language summary
Thigh muscles flexibility deficits contribute to handicap in chronic low back pain patients. The study aims to evaluate the immediate effect of thigh muscles stretching in patients with chronic low back pain. The investigation team suppose that flexibility improvement could be detected by instrumented clinical measurements and such difference could be related to psycho-social factors evaluated by questionnaires.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial tested the immediate effect of hamstring stretching on people with chronic low back pain — do you think tight hamstrings could be contributing to my back pain, and is that worth assessing before I try any stretching program?
2The trial measured flexibility using something called the Active Knee Extension test — is that a test you could do in the office to see where I stand, and would the results actually change how you approach my treatment?
3Since this study only looked at the immediate effect of stretching, not long-term outcomes, what evidence do we have that regular hamstring stretching would give me lasting relief rather than just a short-term change?
4Given that this trial is now completed, have the results been published or shared anywhere, and would reviewing them change your recommendation about whether stretching should be part of my treatment plan?
5Are there other treatments for my chronic low back pain — like physical therapy, core strengthening, or pain management — that have stronger long-term evidence compared to hamstring stretching alone, and should I be considering those first or alongside stretching??

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
