This study aimed to estimate the score of motor FIM (Functional independence measure) of stroke inpatients, which is used as a clinical indicator in rehabilitation medicine, using wearable data recorded in a convalescent rehabilitation ward. We recorded the electrocardiogram and acceleration data of 192 stroke inpatients over a day. To estimate the score of motor FIM, we trained neural network using the wearable data and basic information of inpatients such as weight, height, sexuality and age, and then, performed five-fold cross validation. In the result, the coefficient of determination between estimated FIM by neural network and ground truth scored by therapists showed 0.73 and it was significant (p < 0.001), suggesting the possibility of estimation of motor function of stroke inpatients using activity record obtained with wearable devices.
