I googled standardized response means and found a whole mess of orthopedic papers that use the term. Here's one that defined it and gave a reference: http://www.biomedcentral.com/1471-2474/4/10 The definition: "Responsiveness was calculated as standardized response mean (SRM). SRM is defined as mean score change divided by the standard deviation of that score change [18]. An SRM >0.8 is considered large." The reference (18) is in the paper.
