Can a simple observation scale capture how back pain shows in the body?
NCT ID NCT06113185
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers translated the Pain Behaviour Scale into Turkish and tested how well it measures observable pain behaviors in adults with chronic nonspecific low back pain. About 102 adults aged 18 to 55 performed five standard movement tasks while two physiotherapists independently rated signs such as grimacing, guarding, and limping. The study checks whether different raters agree, whether the same rater stays consistent, and whether the scale relates to disability and fear of movement.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Turkish Pain Behaviour Scale assessment, a clinician-rated observational tool for scoring pain behaviors during physical tasks
- What this could lead to
- If the scale proves reliable and valid, Turkish clinicians and researchers could gain a standardized way to observe and score pain behaviors in adults with chronic low back pain.
- What could go wrong
- This is a small measurement study, so it cannot show whether the scale improves treatment or outcomes. Results may not apply to people with other back conditions or outside the study's age range.

Who is studied
Adults with chronic nonspecific low back pain were recruited using a non-probabilistic sampling strategy from physical therapy and rehabilitation outpatient clinics of private hospitals and a university-based physiotherapy and rehabilitation education and research laboratory. Eligible participants were aged 18-55 years and had chronic nonspecific low back pain lasting longer than 3 months.
