A recent province-wide survey (Alberta, Canada) suggests that clinicians' beliefs about soft lumbar bracing for low back pain (LBP) vary substantially. Approximately 50% of clinicians (MDs, DCs, PTs) find back braces "useful" for acute back pain while the remaining half report that bracing causes muscle atrophy. While previous studies suggest bracing for acute low back conditions can reduce pain and does not cause atrophy, no prior study has assessed back function after bracing using self-reported and objective measures within the same cohort.
