...Stephen L. Demeter, MD, MPH There is an association between obesity and restriction on pulmonary function testing when relying on the forced vital capacity (FVC) as the defining parameter for restriction. Body mass index (BMI) may not be the best measure of obesity, but it is the most commonly used...

An impairment rating does not directly equate to a permanent disability rating and does not solely determine compensation. The AMA...
