Isokinetic Profile of Ankle Joint Muscles in Chronic Non Specific Low Back Pain Patients
Egypt50 participantsStarted 2026-06-13
Plain-language summary
Chronic non-specific low back pain and its resulting infirmity have become a huge health and socioeconomic burden. Low back pain is reportedly associated with decreased activities of daily living and quality of life. Previous literature supports the presence of a link between CLBP and lower limb kinematics that can contribute to functional limitations and disability. For example, CLBP commonly coexist with postural and structural asymmetry. Ankle muscle performance of individuals with LBP during gait becomes more clinically important as it may provide insights into the mechanisms of ankle strategies. The isokinetic testing is an assessment method of high effectivity and trustworthiness that can be used to compare bilateral and agonist/ antagonist ankle muscles strength of normal subjects and athletes. It can be used to analyze muscular performance and differences in muscle performance between dominant and non-dominant limbs.

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 study seems to be measuring ankle muscle strength and movement rather than treating my low back pain — can you explain how understanding my ankle muscle profile could actually help my care, and whether participating would give me any direct benefit?
2Since this trial is listed as 'Phase NA,' which suggests it's an observational or measurement study rather than a treatment trial, does that mean I won't be receiving any new therapy, and should I still be pursuing standard treatments for my chronic low back pain at the same time?
3The study involves isokinetic testing of my ankle muscles on both my dominant and non-dominant sides — how physically demanding is that kind of testing, and are there any risks or discomforts I should know about before agreeing to participate?
4Could the data collected about my ankle torque, endurance, and position help my own doctors better understand what's contributing to my low back pain, or is the information mainly used for research purposes and not shared back with me in a clinically meaningful way?
5Are there other studies or treatment programs currently available for chronic non-specific low back pain that might be a better fit for me right now, compared to joining a study focused on measurement and profiling?

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
