A neuromuscular disease evaluation device that is less invasive, highly sensitive, quantitative and objective, and capable of easily evaluating neuromuscular diseases. A device for evaluating motor functions related to neuromuscular diseases, comprising: a memory unit storing a reference value for evaluating a predetermined movement, which is calculated based on a position of at least one body part; an analysis unit for identifying a position of a body part of the user by analyzing information based on an image captured of the predetermined movement, including the user's body; and an evaluation unit for evaluating the motor function based on the numerical value calculated based on the position of the body part of the user and the reference value.
