【Introduction】We present examples of home rehabilitation for cases with diabetic complications and analyze and discuss the challenges and problems in implementing physical therapy for physical therapy management science in such cases. 【Definition of physical therapy management science】In this paper, physical therapy management science is defined as "a discipline that studies the management of physical therapy so as to provide appropriate services efficiently and safely." There are five viewpoints of physical therapy management science: (1) multidisciplinary management, (2) risk management, (3) infectious disease management, (4) clerical management, and (5) educational management. 【conclusion】As disease patterns change, physical therapists will likely have more opportunities to cater to people with lifestyle-related diseases, especially diabetes. Labeling diabetes as a national disease is not an exaggeration, as it will continue to increase. Establishing comprehensive community care systems will require multifaceted "management" of the knowledge and skills in physical therapy, which is one of the modalities used for treating diabetes.
