A grip strength measurement method and system for animals. Said method comprises: controlling, by means of genome editing technology, the photosensitive protein of an experimental object (204) to express on nerve cells of a particular brain region; irradiating the photosensitive protein using light of a preset wavelength, so as to perform photostimulation on nerve cells of the particular brain region; and receiving, in real time, a grip strength generated by the experimental object (204) after receiving the photostimulation, and calculating a grip strength value.
