Dear AJPM&R readers,
The personal and socioeconomic burden of musculoskeletal disorders is known to be quite significant. This issue of the AJPM&R includes four Research Articles related to this topic, including two studies using experimental models of osteoarthritis. In addition, two articles report on the negative consequences of obesity in persons with disabilities. Because of the increase in both populations, this topic requires attention. Let me conclude with a reminder to the reader that very interesting content is now published online only, including Visual Vignettes and special video submissions.
