A simple method is desired that can evaluate the function of the aged against tumbling. This paper proposes a toe-gap force measurement as an evaluation of the lower-limb function for this purpose. The effectiveness of the method is examined from the viewpoints of anatomy, EMG and general physical strength. In the proposed method, the clipping toe-gap force is measured between the great-toe and the digitus secundus. The toe-gap force in this situation, is generated by the collaboration of the flexor-tensor muscles of the lower-limb, which are supposed to have roles in the effort against tumbling. The measurement device has a structure similar to the dynamometer, and the toe-gap force is displayed by a mechanical structure. As to the physical strength against tumbling, 153 examinees were tested and the results were compared to the indication of the proposed device. It is seen that the measured toe-gap force is closely related to the physical strength of the lower-limb examined by the general examination. It is thus concluded that, the proposed method can be a practically useful method for evaluating quantitatively the function of the lower-limb of the aged against tumbling.
