The purpose of this paper is to discover the implication of the simulator into clinical trainee behaviour, medical education, and patient safety. At the other hand, a methodology of quantitative research design towards implementing Upper Limb Spasticity Simulator (ULSS) named BITA1.0 is discussed. The Descriptive Quantitative Research design is focused on formative clinical assessment with students of Master in Rehabilitation, Universiti Teknologi MARA as subjects with pre and post-response test. With the intention of implementing BITA1.0 into medical education, the result from The Descriptive Quantitative Research is essential.
