Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–65 with clinically or radiologically diagnosed lumbar disc herniation and at least 3 months of low back pain who can walk independently and understand the procedures.
✕Probably not a fit
Individuals with a history of lumbar spine surgery, certain neurological or vestibular disorders, severe balance impairment, rheumatologic disease, pregnancy, or acute conditions preventing assessment may not benefit from this study.

What this trial studies
This study examines the relationship between fear of movement and physical function in adults with lumbar disc herniation. Participants will be 18 to 65 years old with clinically or radiologically confirmed disc herniation and at least 3 months of low back pain. The research explores how psychosocial factors, like fear-avoidance beliefs, correlate with measures of trunk muscle endurance, balance, and functional impairment. No specific interventions are described; the study is observational and aims to better understand factors associated with persistent disability. Conducted at Istinye University in Istanbul, the investigation seeks to inform future approaches to improve outcomes for working-age adults with this condition.
Why it matters
Potential benefit: Findings may help tailor interventions by addressing fear-related barriers to activity, potentially improving function and quality of life.
How similar studies have gone: Previous work supports the relevance of fear-avoidance and psychosocial factors in low back pain outcomes, but specific links to lumbar disc herniation function require further observational data.
