Do posture correctors actually work?

The consensus across the reviewers we read is nuanced: braces and smart trainers can provide short-term relief and act as reminders to sit upright, but physical therapists quoted across communities like r/adhdwomen and r/Posture caution against long-term reliance, noting it can weaken the core and back muscles that maintain posture naturally. Most reviewers recommend using any corrector for limited daily sessions alongside strengthening exercises.
