Abstract
In this study we analyzed reports of accidents occurring during physical therapy, through factor analysis of the accidents. We also reviewed the practical approaches to risk management control on the occurrence of accidents and patients' altered physical condition. From the analysis of 50 cases, we attempted to make a improvement in the risk management system. The problems of the risk management system were divided into 4 topics, medical equipment maintenance, staff education, system construction and routine arrangements, and studied the potential problems. Physical therapists need to perform immediate procedures (basic life support) when a patient's physical condition alters and system procedures putting life-saving first need to be adopted.
