The articles in this month's PTJ demonstrate documentation of effectiveness of current physical therapy interventions, proposed novel interventions, and the application of knowledge to different patient populations. As you listen to this month's Craikcast, keep in mind that—as illustrated in the article by Wiles, Matricciani, Williams, and Olds—in 1945, the typical paper in PTJ was anecdotal, authored by 1.4 US authors who worked in hospitals, and consisted of 4 pages and 4 references. In 2010, the typical paper used a cross-sectional survey or randomized controlled trial design, with 4.6 authors working in universities across the globe, and consisted of 12 pages and 49 references.
