The force used to pick up an object with one upper extremity after picking up a heavy object contralaterally -The influence of the force for the unilateral picking up of an object on the force used on the opposite side-

This research is a re-investigation of the "Generation of excess grip force after picking up a heavier object with the contralateral hand" which was conducted by Noda[1]. Noda[1] reported that information on the weight when picking up an object with the thumb and index finger influences information on the weight when picking up an object with the contralateral arm. The results we obtained in this study agreed with Noda\u27s study[1]. From our study,we confirmed that information on the weight of objects when picking up influenced information on the weight when picking up an object on the opposite side
