New technologies are entering medical practice at an astounding pace. However, these technologies often cause to doctors learn and use difficulties. Then, doctors require assistance of a biomedical engineer. This is currently happening in a local hospital that has new technology to analyze biomechanical protocols in patients. Protocols are used to measure performances and identify changes in human body movements and muscles. Doctors are neither familiar with the concepts nor tools used, so biomedical engineers carry out descriptions of protocols rather than doctors. In this paper, we present the design of a domain-specific language that enables doctors to specify biomechanical protocols by addressing learning barriers (using design patterns). We also make doctors' descriptions compatible with the existing tools, and we also support legacy biomedical descriptions (combining meta-modeling and model transformations).
