How the core and shoulder function relate in people with chronic low back pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study compares people with chronic low back pain to healthy controls to see how core muscle function, especially TrA involvement, relates to upper-extremity reach and scapular stability. It uses ultrasound and clinical assessment to evaluate core capacity and movement control during functional tasks. The goal is to understand whether impaired core stability is linked to poorer upper-extremity performance in this population. No intervention is described; the study focuses on measurement and comparison. Eligible participants are adults aged 18–45 with or without chronic low back pain.
