On a daily basis, practitioners in orthotics and prosthetics collect hundreds of pieces of data that can be integrated into clinical research studies. A well-written research proposal guides investigators through the research process. It describes questions or hypotheses to be studied, the purpose of the study, a review of the literature, how the study will be conducted and how data will be analyzed. The proposal also may include estimates of equipment, supplies, and human and financial resources. The process of research is relevant to the orthotic and prosthetic practitioner's roles as clinician, manager and educator. It should not disrupt the daily routine but should facilitate practice and improve models for service delivery
