Parkinson’s disease (PD) is a common neurodegenerative disease, and its prevalence increases with age. At present, patients with PD in China mainly receive rehabilitation training in community rehabilitation centers or pension institutions, but due to the limitations of objective conditions, they often do not get timely and effective continuous rehabilitation treatment. Under the trend of “internet plus medical care”, in order to better guide rehabilitation training for patients with PD at home, it is necessary to develop an application software (APP) for rehabilitation training for patients with PD at home. This paper discusses the modules and function design of APP from five aspects of health education, rehabilitation training, home renovation, medical record and others, hoping to provide references for the design of related rehabilitation APP.
